Experts refute that breast cancer is getting younger: only 8% of patients are under 35.

Most breast cancer occurs in women, and a small number of men will also suffer from breast cancer. Breast cancer is a malignant tumor that occurs in glandular epithelial tissue of breast, which has great influence on women's physical and mental health. The incidence of breast cancer is not low. Some women around me are very young and think that breast cancer has a tendency to be younger. Is that so?

1, the average age of onset of breast cancer

On March 6th, Professor Shao Zhimin, a well-known domestic breast cancer expert and director of breast surgery in Fudan University Cancer Hospital, said in an interview with The Paper (www.thepaper.cn) that the average age of onset of breast cancer in big cities in China is still around 45 years old, which is about 10 years younger than that in developed countries in Europe and America, and the breast cancer population under 35 accounts for about 8%.

Shao Zhimin also said that after1990s, breast cancer has been in the forefront of female malignant tumors, and this trend continues to this day, becoming the first female malignant tumor, whether in China or in Europe and America. With the progress of medicine and the gradual popularization of screening methods, breast cancer is not a terminal disease in China. Early breast cancer can be completely cured, and intermediate patients can live with tumors for a long time. It can be said that breast cancer is the malignant tumor with the highest survival rate after thyroid tumor, and this treatment level has reached the level of developed countries in Europe and America.

Professor Qin Shihuang, director of the Prevention Department of the Cancer Hospital affiliated to Fudan University, suggested that the screening age should be advanced to 35 years for high-risk groups with family history of breast cancer, "dink" or not breastfeeding, except for women over 40 who need regular checkups. "Existing research has clearly pointed out that timely delivery and breastfeeding can effectively reduce the incidence of breast cancer."

Breast cancer is no longer a "terminal disease"

According to the 20 17 Report on Cancer Status and Trends in China released by the National Cancer Center, breast cancer ranks first among women in China.

The 8-year follow-up data of Prevention Department of Cancer Hospital affiliated to Fudan University (2008-20 16) showed that the number of breast surgery patients in this hospital increased by 157% in the past 8 years, with an average annual growth rate of 12.6%.

Previously, the famous singer Bella and Taiwan Province female artist Asan both died of breast cancer, and there was a saying that "breast cancer is younger" in the society. Shao Zhimin retorted, "The average age of onset of breast cancer in big cities in China is still around 45 years old, which is about 10 years younger than that in developed countries in Europe and America. There is no trend of breast cancer rejuvenation that has been flooding in society, and breast cancer people under the age of 35 only account for about 8%. "

Shao Zhimin said that according to the 8-year survival rate report of breast cancer patients released by the hospital prevention department, the average age of inpatients in breast surgery is 50.8 years old, and the proportions of premenopausal women and postmenopausal women are 565, 438+0.8% and 48.5% respectively. In recent years, the proportion of clinical postmenopausal patients has increased.

"This is different from countries such as Europe and America. In foreign countries, more than 70% of breast cancer patients are postmenopausal patients, while in China, this proportion accounts for half. " Shao Zhimin said.

According to the statistics of Qin Shihuang, from 2008 to 20 15, a total of 20085 patients with stage 0-III breast cancer were discharged from the hospital, and the 5-year disease-free survival rate was 85.5%.

"Breast cancer is no longer a' terminal disease' in people's eyes. Early breast cancer can be completely cured. Patients in the middle and late stage can also achieve long-term survival with tumors through targeted therapy and endocrine therapy. It can be said that breast cancer is the malignant tumor with the highest survival rate after thyroid tumor. " Shao Zhimin said.

According to the existing statistics, the 5-year overall survival rate of carcinoma in situ can reach 97.9%, and it can be completely cured only by surgery without subsequent radiotherapy and chemotherapy. The average 5-year survival rates of stage II and III patients were 75% and 665,438+0%, respectively. "Obviously, with the increase of tumor staging, the survival time of breast cancer patients has obviously declined." Qin Shihuang said.

Women over 40 need regular check-ups.

Different disease spectra also lead to different screening methods and screening accuracy. Shao Zhimin said that B-ultrasound and mammography are two ways to screen breast cancer. Generally speaking, molybdenum target examination is more effective and accurate for postmenopausal people. He also suggested that premenopausal people should choose both B-ultrasound and molybdenum target examination methods to improve the accuracy of screening.

Will this test lead to overtreatment?

Shao Zhimin said that breast cancer, as a tumor of superficial organs, can be detected early through self-examination and screening. Although medical technology has greatly improved the curative effect of breast cancer, generally speaking, medical technology for advanced breast cancer can only improve the curative effect by 30%. Compared with patients with early breast cancer, the risk of recurrence may increase by 50%, so early diagnosis is extremely important.

"From the current investigation and study, screening can effectively detect and treat breast cancer early, reducing the risk of breast cancer death by 30%. Overtreatment is more significant than mortality. Women over 40 years old are currently at high risk of breast cancer, so they should be screened regularly. " He said.

Qin Shihuang also said that in addition to women over the age of 40 who need regular checkups, high-risk groups with family history of breast cancer, "dink" or not breastfeeding need to advance the screening age to 35. "The existing research has clearly pointed out that timely delivery and breastfeeding can effectively reduce the incidence of breast cancer."

As for the self-examination method of breast cancer, experts believe that this self-examination method is not scientific, but it can improve people's attention to this high-incidence disease of breast cancer and provide the possibility for early detection of breast cancer, so experts do not object to this self-examination method.
