Breast cancer is a scary disease for most women. Out of the fear of cancer, many senior breast cancer patients often pursue “radical treatment” and ask doctors to remove the entire breast and even the pectoralis major muscle and lymphatic tissue together, thus leaving a “hole” in the breast. The “hole” created by breast removal surgery poses a great threat to the patient’s psychology and marriage, and reduces the patient’s quality of life. In fact, the results of a standard breast-conserving surgery are identical to those of a traditional mastectomy, and long-term survival can be achieved as well. ”Breast-conserving surgery is called “local excision of the tumor plus axillary lymph node dissection or sentinel lymph node biopsy, followed by radiotherapy”. It has strict indications and mainly depends on the relative size of the tumor and the breast volume. If the tumor is too large for breast conservation, neoadjuvant treatment can be performed first and then breast conservation can be performed after the tumor shrinks. Currently, more than 50% of breast cancer patients abroad undergo breast-conserving surgery, i.e. local excision with radiotherapy. This method can not only eradicate the tumor, but also preserve the shape of the breast, and there is no significant difference in the long-term survival rate and local recurrence rate compared with radical surgery. However, in China, patients often desire “cure” and refuse breast-conserving surgery. Breast-conserving surgery is mainly suitable for early-stage breast cancer patients, while breast cancer in China is usually found in the middle and late stages, so women should be more aware of breast health and actively participate in breast cancer screening. Currently, using molybdenum and palladium photography, ultrasonography, MRI and hollow needle aspiration or vacuum-assisted biopsy and other localized biopsy techniques, breast cancer can be diagnosed at very early stages, even when there are only a few cancer cells. The overall level of breast cancer treatment in China is relatively backward, with a wide span of treatment philosophies in different hospitals and wide differences in the treatment views of different doctors in the same hospital. There is no significant difference between standard breast-conserving surgery and modified radical surgery in terms of local recurrence and long-term survival after treating breast cancer patients. Whether breast cancer is curative or not does not depend mainly on the surgical procedure, but mainly on the early stage of the disease and biological classification as well as the effectiveness and adequacy of systemic treatment. The incidence of breast cancer increases with age and its causes are not yet fully understood, but many risk factors for breast cancer are obvious: gender, age, family history, breast cancer on one side, ductal or lobular carcinoma in situ, atypical hyperplasia of the breast, early menarche, late menopause, obesity, low dose of breast cancer, and the risk of breast cancer. late menopause, obesity, low-dose radiation exposure, etc. According to him, the prevention of breast cancer is mainly to pay attention to high-risk factors and correct poor lifestyle habits and practices, such as smoking, diet high in animal-derived foods, being unmarried, not having children or having the first full-term pregnancy after the age of 30, and not breastfeeding. For young women under the age of 40, Dr. Chiu recommends regular clinical examinations combined with B-ultrasound. Women older than 40 years of age should have annual molybdenum and palladium exams, and after age 50, every two years. High-risk patients can start mammograms earlier than 35 years old, and consider adding MRI if necessary. Women should avoid bad habits as much as possible. From the reproductive point of view, the first full-term pregnancy before the age of 30 and insisting on breastfeeding for more than six months, using less or no estrogen and progestin drugs, minimizing chest radiation exposure and regular checkups can effectively reduce the incidence of breast diseases. Women should fully understand the high-risk factors of breast cancer, detect breast cancer early, carefully choose a treating doctor and carry out standardized and individualized treatment. Women generally should not have molybdenum palladium radiography before the age of 40 Breast cancer threatens women’s health and necessary examinations cannot be missed. Women before the age of 40 should generally not have molybdenum palladium radiography, as repeated radiation exposure may be harmful to the breast. Age, gender, family history, breast cancer on one side, early menarche, late menopause, obesity, low-dose irradiation and mental stress are all high risk factors for breast cancer, among which family history is important. Generally speaking, breast cancer is very rare before the age of 20, uncommon before the age of 30, and the incidence increases significantly from the age of 35. Lifestyle habits such as first full-term pregnancy over 30, not breastfeeding, eating excessive food of animal origin, being overweight after menopause, and long-term estrogen use are also risk factors for developing breast cancer. Early detection of breast cancer is important to ensure clinical efficacy. The main methods of early detection are: self-examination + clinical examination + mammography and ultrasound. Zhao recommends that women between the ages of 18 and 39 should have a clinical breast examination or a combination of ultrasound every 2 to 3 years, women older than 40 should have a mammography every 1 to 2 years, and after the age of 50, every 2 years. He emphasized that women before the age of 35 should generally not receive mammography, as the diagnosis of breast cancer is low at this time due to dense glands and may be harmful to the breast, and repeated irradiation increases the risk of breast cancer. If the mammogram result is BIRADS grade 1 or 2, there is usually no need to go to the doctor, which means that no suspicious breast cancer is seen on the mammogram.
