These organs are the most susceptible to cancer and should be protected when they are 40 years old.

I believe that you often hear about lung cancer, liver cancer, gastric cancer and breast cancer, but rarely hear about cardiac cancer, brain cancer and small intestine cancer.

Isn't that strange? Next, the health headline (micro signal: baojiandaifu) asks the oncologist to tell you why. Knowing this can better prevent cancer.

This is how cancer cells grow.

Our body is made up of many cells. When it needs to grow, a single cell will split into two cells, two cells into four, four cells into eight, and so on, and the division will gradually increase. The external manifestation of cell division is the development and enlargement of body tissues and organs.

Under normal circumstances, cell division will be controlled by genes and will not increase uncontrollably. But when the gene guidance is out of control, cells will divide and grow uncontrollably, and eventually form tumors.

And with the increase of cell division times, gene guidance is more likely to get out of control. This is why cancer becomes common when people are over 40 years old.

Organs with strong regenerative ability are more prone to cancer.

The regenerative capacity of different organs in the body is different, such as liver, lung, intestine and skin.

What do you mean by strong regenerative ability?

Take the liver as an example. Studies have shown that it usually takes three weeks for mice to recover after 75% liver resection, while it only takes four months for humans to recover. But after the brain, heart and other organs are destroyed, it is difficult to repair even if there is enough time.

Of course, strong regenerative ability means that cell division is in a vigorous state, and there are many times of division, which increases the possibility of "mistakes" in gene guidance. Therefore, organs with strong regenerative ability such as liver and lung are more likely to become cancerous.

Organs in contact with the outside world are more likely to get cancer.

Lung, kidney, gastrointestinal tract, etc. Often contact with the outside world, more vulnerable to harmful substances and viruses, such as:

The lungs are often injured by tobacco and air pollution;

The esophagus is often burned by spirits and high-temperature food;

The stomach is often hurt by salty food, barbecue and processed meat products (such as sausages and bacon). ) and helicobacter pylori;

Skin is often damaged by ultraviolet rays;

The large intestine is often invaded by toxins in feces;

The cervix is often destroyed by human papillomavirus;

.

These harmful stimuli will increase the cancer risk of the corresponding organs. The heart and brain are hidden in the body and are rarely directly damaged by harmful stimuli, so the risk of cancer is relatively reduced.

In order to prevent cancer, we should have regular physical examinations and stay away from harmful stimuli.

Seeing this, I believe everyone understands: lung, large intestine, stomach, kidney, liver, esophagus, bladder and lymph. These organs are more prone to cancer, so we should pay more attention to protection.

1. Regular physical examination, early detection of cancer

It is a long process from early single cancer cell to late cancer, not a day or two or a month or two, usually measured in years.

Therefore, friends over 40 should pay more attention to the physical examination of lungs, large intestine, stomach, kidney, liver, esophagus, bladder and lymph.

If you have cancer unfortunately, early detection and treatment through physical examination can greatly improve the treatment effect. If it is already late when it is found, it will be passive to go to treatment.

Stay away from harmful stimuli

Tobacco, spirits, hot food, salty food, barbecue, processed meat products, etc. It is a harmful stimulus that increases the risk of cancer, so try to avoid it.
