It has been proven that a combination of good breast self-examination habits and formal physical examinations is the best method for early detection of breast cancer. The American Cancer Society recommends that breast clinical examinations be performed every three years for ages 20 to 40, annually for ages 40 and older, and annually for mammograms for ages 50 and older. Because of this surveillance mechanism, the United States has one of the highest early diagnosis rates of breast cancer in the world. Women with early menarche and late menopause should be vigilant. Numerous studies have found that risk factors for breast cancer include menarche before the age of 12 or menopause after the age of 55, celibacy, late marriage and high age of first birth, obesity, precancerous lesions such as atypical hyperplasia of the breast or papillomatosis in the breast duct, long-term supplementation of exogenous estrogen after menopause, preference for high-fat and high-protein diet, long-term mental tension and excessive psychological stress, etc. If people develop good habits in daily life, try to avoid risk factors, and carry out proper treatment and standardized monitoring of some high-risk lesions of the breast, the risk of breast cancer will be greatly reduced. Breast cancer detection instruments are not a panacea Breast examination for suspicious people, together with auxiliary examinations such as B-ultrasound and mammography, and finally lump puncture or excisional biopsy to obtain pathological diagnosis are the basic diagnostic methods of breast cancer. However, there is a common problem that people often use ultrasound, CT, MRI or other instruments to replace breast examination by clinicians. In fact, there is a certain rate of misdiagnosis regardless of the instrumentation. Sometimes, some breast cancers are not detected by instruments and are detected by physical examination alone. In addition, clinical examination can provide an important reference for the judgment of the instrumentation results, and the emphasis on instrumentation rather than physical examination may lead to some breast cancers being missed. In addition, even women who have annual physical examinations should pay attention to the changes of their breasts to see if there are painless lumps, nipple depressions, nipple deviation to one side and other problems. Breast cancer treatment is a combination of chemotherapy, surgery, endocrine, radiotherapy and molecular targeted therapy. One of the misconceptions in breast cancer treatment is the supremacy of surgery. Many people still believe that surgery is the main treatment for breast cancer, while chemotherapy and endocrine therapy, which are very important treatments, are arbitrarily discarded or not applied in a standardized way. Do not blindly believe in “partial prescription”, “secret formula” or “anti-cancer Chinese medicine” for breast cancer treatment. Chinese herbal medicine can improve the general condition of breast cancer patients, increase immunity and reduce the side effects of chemotherapy and radiotherapy, but its effect on killing tumor cells is not exact. In my clinical work, I have seen some patients blindly relying on “secret Chinese medicine recipes” and avoiding scientific and effective methods such as chemotherapy and surgery, which led to delayed treatment and caused tragedies that should not happen.
