Recently, I have met many patients who came to the clinic for checkups because they heard that others had breast cancer, which is a sign that the majority of women have improved their self-health. However, when it comes to breast enlargement and breast cancer, most of them look nervous. With the experience of long-term breast disease treatment, I think it is necessary to talk about the general knowledge of common breast diseases. The breast is an important organ of women. In addition to the practical functions of lactation and breastfeeding, it is also an important manifestation of female beauty and maternal characteristics. As women’s lifestyles change and their participation in social activities increase, the beauty of the breast has become an important part of women’s image and self-confidence, and the beauty of the breast has become an important role of the breast, and the impact on women’s quality of life is becoming more and more prominent. Therefore, once breast diseases appear, especially when breast cancer is mentioned, women will immediately get nervous. In fact, breast disease is not a terrible disease, we must first understand it correctly in order to better overcome it. Breast cancer is one of the most common diseases among women, and there is a trend of increasing year by year, and the age of onset is relatively younger. People generally think that cancer is incurable and there is no hope if you have cancer, and some patients even refuse treatment, which is an extreme misconception. Breast cancer is a common disease and can be cured by early detection and early treatment. Through systematic and comprehensive treatment, the effect of intermediate and advanced breast cancer is also very good, and the survival period can reach more than seven years or even longer. Therefore, a correct understanding of breast cancer and confidence is the key to overcome it. What kind of conditions in the breast should be taken seriously? There are three major symptoms of breast cancer, which are pain, lump and nipple overflow. Breast pain does not necessarily mean breast cancer. Periodic breast pain is closely related to endocrine and can often be relieved by itself, mostly as a manifestation of breast hyperplasia. The pain caused by breast cancer usually does not change with menstrual cycle, so non-periodic breast pain should be paid more attention to the possibility of breast cancer, even if it is not breast cancer, it should be paid attention to because cystic hyperplasia of breast can also appear as non-periodic breast pain, and cystic hyperplasia is considered by some as precancerous lesion, which should also be treatment. Nipple discharge is mostly physiological and a few are pathological. Generally, unilateral, spontaneous, intermittent bloody discharge is considered to be a possible case of intraductal papilloma or breast cancer, while a large amount of thin, watery discharge, although rare, is more likely to be breast cancer. Therefore, for nipple discharge, ductoscopy or smear cytology should be performed to clarify the diagnosis. Breast lumps are one of the most important clinical manifestations of breast cancer, and some may be the only clinical manifestation of breast cancer patients. Therefore, once a breast lump is found, it should be taken seriously and a specialist should be consulted for further diagnosis. In fact, clinically, we found that many breast lumps found by self-examination are not really breast lumps, but most of them are mistaken as lumps due to incorrect examination technique. Therefore, learning the correct self-examination method can reduce a lot of unnecessary worries and panic. The key to improve the treatment effect of breast cancer is early detection and early treatment, how can early detection be achieved? Numerous studies have proven that screening is the key to effectively reduce mortality. The combination of mammography and clinical examination is the most reasonable screening method at present. Screening should focus on high-risk groups, which can advance the diagnosis of breast cancer by 2-4 years. At present, it is believed that women should have a monthly breast self-examination from the age of 20 and a clinical breast examination by a specialist every 3 years; a baseline mammogram should be performed over the age of 35 as a control material to judge the disease later, and a mammogram should be performed annually for women over the age of 40. For women with a family history of BRCA1 and BRCA2 mutations, they should also have a clinical examination every 6-12 months and a mammogram every 12 months, starting at age 25-35. Breast self-examination is best done in a lying position, with the index, middle and ring fingers together, using the fingertips to make circular pressure movements, from the armpit – upper outer – lower outer – lower inner – upper inner – areola – supraclavicular lymph nodes in a continuous check, not missing any part of the breast. Once a suspicious problem is found, seek further examination by a specialist. In this way, early diagnosis and treatment can be achieved for good results. Once you have breast cancer, some people are so desperate and desperate that they refuse to treat it. In fact, the treatment of breast cancer is a sequential and comprehensive treatment, which requires a specialist to make an individualized treatment plan according to the patient’s different stages, risk level, immunohistochemistry results, etc. It is never an unordered superposition of surgery, radiotherapy, chemotherapy, endocrine therapy and biological targeted therapy, but different treatments in sequence. If patients can receive regular comprehensive treatment, the treatment effect of breast cancer is very good and can achieve long-term disease-free survival, even without affecting life and labor. Even if you have advanced breast cancer, you can still receive neoadjuvant radiotherapy first, and then wait until a certain time to remove it, and you can achieve satisfactory results. For young women, once they have breast cancer, they may be reluctant to receive treatment for fear of losing their breasts. Breast cancer does not necessarily require removal of the breast, or even axillary lymph node dissection. If the breast cancer lump is far from the areola and the lump does not fight, radical breast cancer surgery can be performed to preserve the breast. If the axillary lymph nodes are negative and the sentinel lymph node biopsy is negative, axillary lymph node dissection can be avoided to better preserve the function of the upper limbs. Even if patients must have their breasts removed, they can undergo immediate postoperative breast reconstruction by transferring abdominal fat and some muscles to the breast area, which can remove abdominal fat and reshape the breasts, as well as achieve aesthetic results. Therefore, having breast cancer is not a scary thing, the key is to face it squarely. It is neither incurable nor hopeless, and as long as the right methods are used, we can overcome it with a reasonable combination of all means and return beauty and health to women.
