What causes breast cancer? Many factors

There are many factors that lead to the occurrence of breast tumors, the most common of which are viral factors and endocrine factors, especially endocrine factors. Many women with breast tumors have endocrine disorders. Frequent depression can also easily cause breast diseases, so good care is required.

1. What causes breast tumors?

1. Virus factors (30%):

Virus particles can be transmitted through breastfeeding, causing the disease. This has been confirmed by many animal experiments. Therefore, some scholars speculate that the cause of breast tumors may be viruses, but there is currently insufficient epidemiological evidence and further research is needed.

2. Endocrine factors (30%):

Endocrine disorders may also cause breast tumors. Due to the long-term abnormal stimulation of endocrine hormones on the breast, breast tissue may become tumorous. Among them, estrogen and progesterone are the two endocrine hormones most closely related to breast malignancy. This has been confirmed by many clinicians, pathologists and physiologists.

3. Genetic susceptibility (20%):

Clinical data from family history surveys show that genetic factors are also one of the important causes of this disease. Especially for women with bilateral breast tumors and those who develop the disease at a young age, the risk of these women developing the disease is 9 times that of ordinary women. This may be related to genetic factors, which make them more susceptible to breast tumors.

Tumor susceptibility and internal causes of the disease.

4. Other factors (20%):

The body's anti-tumor immune function is low, which suppresses the immune function of anti-tumor factors; and traumatic stimulation of the breast and radiation damage are all factors that predispose to breast tumors.

2. Breast cancer care

1. Exercise regularly: Recently, a research report published in the Journal of the American National Cancer Society pointed out that exercise can reduce the incidence of breast cancer in women before and after menopause by 60%. A Norwegian research institute conducted a survey of 25,624

A survey of women found that those who exercised at least 4 hours a week had a 37% lower risk of breast cancer.

2. Control your weight: Exercise can prevent breast cancer. The fundamental reason is that it can control body weight gain. A Harvard University study reported that women who gain weight rapidly after the age of 18 have a lower risk of developing obesity than those who maintain a normal weight for a long time.

Compared with obese women, their risk of developing breast cancer after menopause is almost doubled.

3. Don’t drink alcohol: American experts believe that if you drink alcohol once a day, your risk of breast cancer increases by 11%; if you drink twice a day, the risk is 24%; if you drink more than twice a day, the risk is 10%.

The risk increases to 40%. Therefore, ladies who like to drink are advised to drink no more than three times a week and drink in moderation.
