See a doctor, breast cancer

Most malignant tumors of the breast come from epithelial tissues of the breast (breast cancer), and a few can come from various non-epithelial tissues of the breast (all kinds of sarcomas), and occasionally mixed carcinosarcoma. The incidence of breast cancer is increasing year by year, and the population incidence is 23/65438+ 10,000. It accounts for 7 ~ 10% of all kinds of female malignant tumors.

What causes breast cancer?

The etiology of breast cancer is not completely clear, and some confirmed pathogenic factors are still controversial. Premenopausal and postmenopausal estrogen is an obvious factor to stimulate breast cancer. In addition, genetic factors, dietary factors, external physical and chemical factors and some benign breast diseases are all related to the occurrence of breast cancer.

What are the symptoms of breast cancer?

The earliest manifestation of breast cancer is a single, painless and progressive small lump in the breast. The most common mass is located in the outer upper quadrant, followed by nipple, areola and inner upper quadrant. Because there are many unconscious symptoms, the lump is often found by the patient unintentionally (such as taking a shower and changing clothes). A few patients may have different degrees of tenderness or irritation and nipple discharge. Tumors grow faster, and invading surrounding tissues will cause changes in the shape of breasts and a series of signs will appear. Such as: skin depression on the tumor surface; The cancer adjacent to the nipple can pull the nipple towards the cancer; Nipple invagination etc. If the cancer mass is large, it can make the whole breast tissue contract and the mass protrude obviously. Cancer cells continue to grow, forming a so-called "orange peel" change. These are all important signs of breast cancer.

Breast cancer invades superficial skin in the late stage, which can lead to skin induration and even skin ulceration. The cancer invades deeply, which can invade the thoracic fascia and chest muscle, causing the mass to be fixed on the chest wall and difficult to push.

Lymphatic metastasis of breast cancer is mostly manifested as ipsilateral axillary lymph node enlargement, which is scattered, painless and hard at first, and the number is small, which can be promoted; After that, the swollen lymph nodes increased, adhered to each other, and attached to the skin or deep tissues of the armpit to be fixed. A few patients may have contralateral axillary lymph node metastasis.

When the distant metastasis of breast cancer reaches the lungs, chest pain, shortness of breath and hydrothorax may occur; When vertebrae are transferred, the affected part is severely painful and even paraplegic; When liver metastasis occurs, jaundice and hepatomegaly may occur.

It should be noted that some special forms of breast cancer (such as inflammatory breast cancer and papillary eczema-like cancer) have different development laws and clinical manifestations from general breast cancer.

What tests does breast cancer need to do?

Biopsy is of great significance in the differential diagnosis of breast masses with unknown nature and highly suspicious cancers.

How to treat breast cancer

There are many treatment methods and measures for breast cancer, including surgery, radiotherapy, chemotherapy and endocrine therapy. At present, comprehensive treatment based on surgery is widely used.

1. Surgical treatment: Radical mastectomy has a history of 100 years, and it is still the main treatment method for breast cancer, with the most satisfactory curative effect for early breast cancer without axillary lymph node metastasis.

2. Radiotherapy: usually used after surgery to prevent local recurrence. Radiotherapy for advanced breast cancer can shrink the tumor, and some even can transfer breast cancer that is not suitable for surgery to operable resection. It has a certain palliative effect on isolated local recurrence and bone metastasis of breast cancer. However, for patients with early breast cancer without lymphatic metastasis, conventional radiotherapy is not necessary to avoid damaging human immune function.

3. Endocrine therapy: For primary advanced breast cancer that is not suitable for surgery or radiotherapy, estrogen receptor positive patients can receive endocrine therapy alone or in combination. The drugs and methods used vary according to menstrual conditions.

4. Chemotherapy: Chemotherapy is a necessary systemic adjuvant therapy (cyclophosphamide, lomustine, chlorambucil).

Incidence and population

Breast cancer is the most common and important breast disease, with an incidence rate of 23/65438+ 10,000. The main clinical manifestation is milk lump. This disease mostly occurs in women aged 40-60, that is, before and after menopause. The occurrence of this disease may be related to the disorder of sex hormones. Breast cancer can also occur in men, often secondary to male breast hyperplasia. Surgical treatment is still the main treatment of this disease, so early diagnosis and early surgical treatment are the key.

clinical picture

1. Painless lump appears in the breast, which increases rapidly, local skin can be sunken or "orange peel-like" changes, and nipples can be raised or invaginated.

2. The lump is hard and not smooth. Can be fixed with skin or pectoralis major.

3. The axillary lymph nodes on the same side can be enlarged.

Diagnostic basis

1. Breast painless lump, hard and not smooth.

2.x-ray molybdenum target assisted diagnosis.

3. Diagnosis can be made by needle aspiration cytology or biopsy.

Medication principle

1. Chemotherapy is a necessary systemic adjuvant therapy, which can kill cancer cells that spread in the blood circulation, which cannot be achieved by surgery or radiotherapy. Therefore, for all stages of breast cancer, a variety of drugs can be combined for anti-cancer treatment, and the drug restriction is mainly "A".

2. For breast cancer patients with bone metastasis or estrogen receptor positive, hormone therapy should be supplemented. The drug restriction is mainly "B", and advanced patients can choose "C" drugs.

accessory examination

1. Check box "A" is the main item for patients with early breast cancer;

2. Patients with advanced stage need to know the distant metastasis, and the examination items may include "A", "B" or "C".

Curative effect evaluation

1. cure: after modified radical resection, the incision healed without complications.

2. Improvement: palliative resection of tumor, wound healing, no complications, or after non-surgical treatment, the mass shrinks.

3. Non-union: the tumor has not been removed, and the mass has not shrunk after non-surgical treatment.

Can breast cancer be inherited?

There are genetic and non-genetic types of breast cancer. Generally, postmenopausal unilateral breast cancer is non-hereditary, while premenopausal bilateral breast cancer is often hereditary. If only breast cancer occurs, it is generally polygenic inheritance. In this case, the risk of their offspring suffering from this disease is 7-8 times that of ordinary people, and the incidence rate is 10%. If you have not only breast cancer, but also soft tissue sarcoma, then your offspring have a chance of getting this disease above 50%.

The older generation suffered from breast cancer when they were young, so the next generation may have a higher risk of breast cancer than others, but to accurately predict the genetic risk, we should also consider the diseases of other members of their family and the medical history of the older generation. At present, it is impossible to test whether someone may have breast cancer through medical examination. However, modern medicine has advanced diagnosis and treatment methods for breast cancer, and has developed the habit of self-examination and breast detection. It often goes to regular hospitals for regular examination to find and eliminate risk factors early. And pay attention. Because many girls have sunken nipples, it may be breast cancer.

(Traditional treatment): At the beginning, it is appropriate to soothe the liver and relieve depression. You can take Shen Xiao Fructus Trichosanthis powder, Ru Yan Fang, Huang Xi Pill, or Huang Xi Pill and Milk Soup alternately in the morning and evening. 6 toad venom for external use. One opens his belly every morning and evening, puts the skin on the wound and detoxifies it. Change it once a day. There is no cure.

Dietary therapy for breast cancer

Dietary principles of breast cancer ● Be flexible in treatment. Breast cancer patients should try to eat and supplement nutrition before and after operation. During radiotherapy, the patient's diet should be light and palatable, and it is not advisable to eat more thick and greasy products.

● Reasonable arrangement and skillful cooking. After completing the treatment plan, it is very necessary for breast cancer patients to choose foods that are beneficial to breast cancer prevention and treatment.

Eat more seafood: seaweed, kelp, jellyfish, sea cucumber, mussels, oysters and so on.

Beans: mung beans, red beans, mung bean sprouts, etc.

Dishes: taro, water chestnut, water bamboo, wax gourd, mushrooms, Hericium erinaceus, mushrooms, tomatoes, etc.

Fruits: oranges, apples, hawthorn, fresh kiwifruit, etc.

Others: tortoise, soft-shelled turtle, snakehead, coix seed, fungus and other foods.

● White ginseng or American ginseng should be taken according to the condition during treatment. After treatment, you can still supplement ginseng for every winter.

● Diet should be moderate and not excessive. Overnutrition and obesity have adverse effects on the treatment of breast cancer. In the long-term life after treatment, breast cancer patients should adhere to the principle of moderate diet on the premise of ensuring nutritional needs. In the dietary arrangement, it is necessary to know the total amount of calories, fat and sugar consumed every day to avoid overeating.

Prognosis of breast cancer

There are many factors affecting the prognosis of breast cancer, the most important of which are the tumor infiltration range and pathobiological characteristics.

(A) the scope of tumor invasion

1. tumor size: in the absence of regional lymph node metastasis and distant metastasis, the larger the primary focus, the more serious the local infiltration and the worse the prognosis.

2. Axillary lymph node metastasis: the prognosis of axillary lymph nodes is good when there is no metastasis, but poor when there is metastasis. And the more metastases, the worse the prognosis. The metastatic site is high and the prognosis is poor.

3. Distant metastasis: the death exceeds 1 year.

(II) Pathological type and differentiation degree of tumor Pathological type and differentiation degree of tumor, invasion of tumor and host's immunity to tumor are important factors affecting prognosis. The prognosis of special breast cancer is better than that of non-special breast cancer, non-invasive cancer is better than invasive cancer, and well-differentiated tumor is better than poorly differentiated tumor. Some tumors are highly malignant, and necrosis can occur when they grow rapidly. Severe tumor necrosis indicates that the tumor is aggressive and has a poor prognosis.

(3) Clinical staging TNM staging is familiar to clinicians, with high staging and poor prognosis. However, two things need to be recognized. First, the cases belong to the same stage in staging, and whether axillary lymph nodes metastasize is more important than tumor size; Second, there are often errors in clinical axillary lymph node examination for metastasis.

(4) Determination of steroid hormone receptors and prognosis The determination of steroid hormone receptors can be used not only as a reference for selecting hormone therapy, but also as an index for estimating prognosis. The prognosis of patients with positive receptor is better than that of patients with negative receptor, and the difference between them is about 10%, especially in patients with positive lymph node metastasis. Among estrogen receptor and progesterone receptor, progesterone receptor is more important, and the prognosis of those who are both positive is better than those who are both positive or negative. There are many statins that affect the prognosis of breast cancer, and the relationship between them is very complicated. All factors should be integrated to estimate the prognosis of patients.

There are many statins that affect the prognosis of breast cancer, and the relationship between them is very complicated. All factors should be integrated to estimate the prognosis of patients.

The main factors affecting the prognosis are as follows:

(1) Clinical difficulties;

(2) Age: It is generally believed that young patients have rapid tumor development, high lymph node metastasis rate and poor prognosis;

(3) Primary focus size and local infiltration: In the absence of regional lymph node metastasis and distant metastasis, the larger the primary focus, the more serious the local infiltration and the worse the prognosis;

(4) Lymph node metastasis;

(5) Pathological type and differentiation degree of tumor;

(6) Steroid hormone receptor;

(7) cell proliferation rate and DNA content;

(8) Oncogenes.

The cause of breast cancer has not been solved, so the means that can really be used for primary prevention are extremely limited. However, we can cautiously put forward several measures to reduce the risk of breast cancer, such as properly controlling the fat and protein intake of animals in adolescence, increasing physical activity, encouraging breast-feeding babies, avoiding the use of estrogen for menopausal women, appropriately increasing physical activity after menopause, controlling the total calorie and fat intake, and avoiding unnecessary radiation exposure.

Surgical treatment of breast cancer has a long history, and the scope of surgical operation is also different. In recent years, due to the new concept of breast cancer development, some people think that breast cancer is a systemic disease from the onset. At the same time, in order to preserve the appearance and upper limb function of the breast, a variety of operations smaller than total mastectomy were performed, and radiotherapy and chemotherapy were used comprehensively. In Europe and America, the application of radical surgery or modified radical surgery is decreasing day by day. The cases of local excision and radiotherapy have reached 20% ~ 30% of breast cancer patients, and breast reconstruction is also considered. At present, in the diagnosis and treatment of breast cancer, it is not only satisfied with whether it is a malignant tumor or not, but also requires providing reference data for postoperative treatment and prognosis estimation, such as observing vascular and lymphatic infiltration, determining receptors, detecting DNA content and distribution in each phase of cell cycle by flow cytometry, and applying monoclonal antibodies for diagnosis and treatment. In recent years, with the deepening of oncogene research, many genes related to the prognosis of breast cancer have been found. It is expected that in the near future, people can judge the prognosis of patients through various tests, and then choose appropriate adjuvant treatment for cases with high recurrence risk to improve the cure rate. There are the following aspects:

(1) Clinical difficulties;

(2) Age: It is generally believed that young patients have rapid tumor development, high lymph node metastasis rate and poor prognosis;

(3) Primary focus size and local infiltration: In the absence of regional lymph node metastasis and distant metastasis, the larger the primary focus, the more serious the local infiltration and the worse the prognosis;

(4) Lymph node metastasis;

Breast cancer staging

Clinical staging of breast cancer refers to the growth and spread of tumor, and the staging is mainly determined according to clinical manifestations, such as the spread range of tumor, the spread along lymph and blood channels, detailed medical history, physical examination and a series of other examinations. The clinical stages of breast cancer are summarized as follows:

TNM international staging method

Staging of primary tumor (t):

Tx primary tumor unknown (resected).

T0 Primary tumor is untouchable.

Tis carcinoma in situ (including lobular carcinoma in situ and intraductal carcinoma), Paget's disease is confined to nipple, and no mass is touched in breast.

T 1 The maximum diameter of tumor is less than 2Cm.

The maximum diameter of T 1a tumor is less than 0.5cm.

The maximum diameter of T 1b tumor is 0.5 ~ 1cm.

The maximum diameter of T 1c tumor is 1 ~ 2 cm.

The largest diameter of T2 tumor is 2 ~ 5 CrN.

The maximum diameter of T3 tumor is more than 5 cm.

T4 tumor of any size directly invades the chest wall and skin.

T4a tumor directly invaded the chest wall.

T4b Skin edema on breast surface (including orange peel edema), skin ulcer or satellite nodule around tumor, but not more than ipsilateral breast.

T4c includes T4a and T4b.

T4d inflammatory breast cancer.

Regional lymph node (n) staging:

There are no palpable regional lymph nodes.

The lymph nodes in Nx area are unknown (previously removed).

N 1 ipsilateral axillary lymph nodes are swollen and movable.

N2 ipsilateral axillary lymph nodes are swollen, fused with each other, or adhered to other tissues.

N3 ipsilateral internal mammary lymph nodes have metastasis.

Distant metastasis (M) stage:

Whether Mx has distant transfer is unknown.

M0 has no distant metastasis.

M 1 distant metastasis (including ipsilateral supraclavicular lymph node metastasis).

Clinical staging: According to the above different TNM, different clinical staging can be formed:

0 phase TisN0M0

The first stage T 1N0M0

T0n1m 0 in phase Ⅱ a; ; T1n1* m0 (* n1has the same prognosis as N0); T2N0M0

Phase Ⅱ b T2n1m 0; ; T3N0M0

ⅲa t0n2m 0； ; t 1n2m 0； T2N2M0T3N 1，2M0

Iibt4, any n, m0; Any t, N3M0

Ⅳ any t, any n, M 1

At this stage, Tis can only have paget's disease confined to nipple, other cancers in situ can't be diagnosed clinically, and N3 (internal mammary lymph node metastasis) can't be touched clinically.

Breast cancer prevention

Starting from eating "blocking" breast cancer, we must be willing to "eat delicious food"

There is a joke that the incidence of breast cancer in Shanghai is "thriving" with the weight of Shanghainese. Someone is going to ask, what is the relationship between weight and breast cancer? It's a big relationship. Just look at this set of data: if the standard weight is 70 kg, the incidence of breast cancer will increase by 20% for every increase of 10 kg, while the risk of breast cancer will increase by 80% for women around 60 years old. This number is still very scary!

Why is Shanghai the national champion of breast cancer incidence? In my opinion, it is largely related to the improvement of living standards of Chinese residents and the change of food structure. Statistics show that the proportion of fat in the dietary structure of urban residents in Shanghai was 9.5% in 1959, rose to 24.2% in 1982, and reached 3 1.2% in 1992, exceeding the limit of 30% recommended by the World Health Organization and approaching. Although there is no statistics now, this data is definitely higher. Too much fat in the human body can be converted into estrogen-like, which can stimulate breast tissue proliferation. Needless to say, the result. In addition, a large intake of fat will also lead to a decline in the body's immune function, thus giving cancer an opportunity. From the perspective of preventing breast cancer, it is necessary for lesbians to maintain the traditional habit of eating low-fat and high-fiber diet.

For "fat" lesbians, I suggest that they eat less meat and high-fat food, and go to the hospital for regular check-ups. Many people are reluctant: "If you don't eat this, you won't eat that. What's the point of living! " I told them that if they can't bear this "delicious food", there is another way, and that is to exercise more and exercise regularly for a long time. In all walks of life, athletes have the lowest incidence of breast cancer. They do a lot of exercise every day, consume excess fat, have no fat, and keep estrogen at a low level in their bodies. Of course, they will not be "infected" with breast cancer. Some people abroad have done statistics. Women of childbearing age take an average of 4 hours of physical exercise every week, and the risk of breast cancer will be reduced by 60%.

Avoid drinking: For women, drinking is much more harmful than men. Women who drink alcohol have a higher risk of breast cancer than those who rarely drink alcohol. People who drink 1 cup or more every day have a higher risk of breast cancer than those who rarely drink, which is most significant among premenopausal women. At present, it is believed that alcohol can stimulate the secretion of prolactin in the anterior pituitary gland, and prolactin is related to the breast.

Cancer is related. Therefore, women, especially those before and after menopause, should give up drinking or drink less.

Drink less coffee: coffee, cocoa, chocolate, these foods contain a lot of caffeine, xanthine can promote breast hyperplasia, and breast hyperplasia is related to breast cancer. If women, especially premenopausal women, eat too much of this kind of food, with the intake of caffeine, the risk of breast cancer will greatly increase. Therefore, women, especially those over middle age, should drink less coffee and eat less chocolate.

Eat more Chinese cabbage and bean products: Chinese cabbage contains a compound, accounting for about 1% of the weight of Chinese cabbage, which can help decompose estrogen. Soybean products contain isoflavone, which can effectively inhibit the occurrence of breast cancer. In addition, corn, edible fungi, seaweed, garlic, tomatoes, oranges, berries and other fruits and vegetables also have a role.

Eat more fish: According to relevant reports, women who eat less fish in the United States, Switzerland, Canada and New Zealand have a higher incidence of breast cancer, while women who eat more fish in Japan have a lower incidence of breast cancer. Experts say that fish contains a fatty acid that can inhibit the proliferation of cancer cells. Eating more fish regularly and in moderation is very beneficial to prevent breast cancer.

Don't eat health care products indiscriminately

Now that everyone's living standard is high, many women who love beauty are worried about their "premature death" and often take some female health products. Especially after entering menopause, when symptoms such as insomnia and mental stress appear, they are even more panicked. Relatives and friends often give them health care products as gifts for the purpose of concern. As everyone knows, if you don't do well, you will "spend money to suffer" and "do bad things with good intentions." Not long ago, I met a female patient in her forties. She usually pays great attention to her diet and has no family history. She said she didn't believe she had breast cancer. She said, "I have been taking XX brand oral liquid for six months. Will I still get sick? " I immediately told her, "That's the problem. Nine times out of ten, this problem is caused by health products. "

What I said is well founded. Many female health products on the market now, including many well-known brands, contain a certain amount of estrogen. Estrogen is a "double-edged sword", which can indeed prolong the "puberty" of women, but it also brings about the proliferation and even canceration of mammary duct epithelial cells. So don't believe in advertisements. The choice of health care products should vary from person to person. If you can't eat, try not to eat, you must eat, and you must know the ingredients. If you are not sure, ask a doctor more, take it under the guidance of a doctor, take it for granted, and be careful not to regret it.

Don't be too late.

Many urban women are unwilling to give birth or postpone giving birth after the age of 30 in order to keep fit because of the tight work rhythm, which is very unacceptable. Because this is likely to make them lose an opportunity to enhance their ability to resist breast cancer. Why do you say that? Women's first full-term pregnancy can lead to a series of changes in mammary epithelial cells and make them mature, which makes epithelial cells more resistant to gene mutation and produces a lot of progesterone. Progesterone is very useful for protecting breast health and is the "rival" of estrogen. Estrogen makes breast tissue proliferate, and progesterone comes out to "reduce swelling". Therefore, although pregnancy, childbirth and breastfeeding are hard, they not only bring lovely next generation to female compatriots, but also greatly enhance women's disease resistance. The sooner you get this ability, the better it will be for preventing breast cancer.

The Singapore Cancer Research Center conducted a survey and found that the risk of breast cancer among childless women is much greater than that of women who have given birth. This risk increases with age. The risk of breast cancer in women who give birth after the age of 30 is 2 to 5 times higher than that in women who give birth to their first child before the age of 20. The incidence of female breast cancer in eastern and western Germany is obviously different. The incidence of breast cancer among women in the former East Germany was much lower. Later, it was found that the main reason was that women in the former East Germany generally gave birth earlier, with an average of 3 to 5 children. Therefore, I suggest that lesbians should take this into account when choosing whether or not to have children and when to have children.

Start with dolls.

Seeing this title, some people may say that I have made a mountain out of a molehill, but I want to seriously warn everyone that this issue must attract enough attention from parents. Breast cancer is mainly an adult disease, but it has shown a trend of younger age. The youngest patient I have treated is only 15 years old. How did you get this disease when you are so young? I was surprised at first, too After careful understanding, it is found that she is a typical precocious puberty with menarche age of 1 1. Usually, grandparents, grandparents and parents are very loving, and she has been eating nutrients and supplements. I told them that your "baby" child didn't help, and the disease may be related to eating too many supplements and too many sex hormones. Parents are stupid when they listen!

Children nowadays are generally only children. Parents naturally regard it as the apple of their eye and try their best to increase nutrition for their children. A high-fat and high-calorie diet doesn't count. They also blindly buy children's food from the market to supplement their health. Many supplements contain hormones, which can accelerate the growth and development of girls. According to statistics, the age of menarche of Shanghai girls is advanced from 16 to 13. The beginning of menarche indicates that children begin to develop sexually, and estrogen begins to act on breast tissue. The prolonged menstrual history of women means that the longer the breast tissue is exposed to estrogen, the greater the possibility of getting sick.
