Do you know what is the most prevalent malignancy in the world? The answer is only three words: breast cancer!
Although breast tissue is found in both men and women, 99% of breast cancer patients are women. Even so, the incidence of breast cancer in 2021 also surpassed lung cancer, becoming the most common malignancy in the world, and the most common malignancy in women.
Although mainland women pay more and more attention to breast health, many women also have the habit of regular physical examination.
However, there are still many women who do not realize the importance of breast health, so that in mainland China, many breast cancer patients have entered the development stage when they are diagnosed, or even entered the middle and late stages, and the prognosis effect is not ideal.
Therefore, the clinic has always emphasized the importance of preventing breast cancer, and high-risk women should be screened for breast cancer regularly. So the question is, which women are more likely to have breast cancer?
1. Menstrual abnormalities
A large number of studies have confirmed that the incidence of breast cancer is closely related to endocrine, and abnormal manifestations of menstruation in women may increase the chance of future cancer.
For example, women with menarche are less than 12 years old, and the risk of breast cancer will increase by about 2.2 times compared with women with menarche at normal age. If a woman's menopause exceeds the age of 55, or even over 60, the risk of breast cancer increases by 1 times. Therefore, in the clinical view, late passage and premature menarche are the main risk factors for breast cancer;
2. Marriage and childbearing
While everyone has the right to choose whether to marry, have children and breastfeed, these factors can have an impact on women's health.
Relevant data studies show that fertility and breastfeeding have a certain protective effect on women's mammary glands, especially women who have full-term production and breastfeeding before the age of 30, compared with women who are married and do not breastfeed, infertile women, the risk of breast cancer is about 2 times lower;
3. Contact with radiation
Breast tissue and thyroid tissue are similar and are sensitive to the carcinogenic activity of ionizing radiation. Especially in young women, the mammary glands themselves are in the stage of mitosis activity and are relatively sensitive to ionizing radiation.
If a woman is exposed to low doses of ionizing radiation for a long time, or if she receives a large dose of ionizing radiation at one time, the likelihood of breast cancer increases;
4. Genetics
From the moment of birth, some people are doomed to have a higher cancer rate than others in the future, which is mainly related to genetics. Relevant data surveys show that if the mother has bilateral breast cancer before menopause, the risk of future breast cancer is 9 times that of other women.
Not only that, but what is even more frightening is that the second generation of breast cancer patients, the age of breast cancer, is about 10 years earlier than other groups;
5. There is cystic hyperplasia of the breast
This is a type of pathological hyperplasia, according to epidemiological research surveys, breast cystic hyperplasia patients have a chance of breast cancer in the future, about 2-4 times that of normal people.
Of course, not all cystic hyperplasia will occur cancerous, whether it will be malignant, mainly related to the degree of hyperplasia of the ductal epithelium, if the patient in the cystic hyperplasia at the same time, but also accompanied by epithelial atypical hyperplasia, especially severe epithelial atypical hyperplasia patients, the probability of future cancer is relatively large, belongs to the clinical precancerous lesion stage.
6. Unhealthy eating habits
The incidence and mortality of breast cancer are related to per capita digested fat. Even related studies have shown that due to obesity caused by dietary factors, long-term maintenance of "high calorie, high fat" eating habits, the incidence of breast cancer will be greatly improved;
Finally, I would like to remind everyone that the incidence of breast cancer is not simply the result of a factor. In clinical view, any outbreak of cancer is the product of a multi-factor combination of factors. However, it cannot be denied that the above groups of people are indeed at high risk of breast cancer, so it is still very necessary to conduct regular targeted anti-cancer screening of the breast.
