Breast lumps are a common symptom and sign of breast cancer, usually single, variable in shape and hard and tough. The most common symptom of metastasis is enlarged axillary lymph nodes, and a few supraclavicular and cervical lymph nodes may also be enlarged. When breast cancer reaches advanced stage, most of them can show symptoms such as wasting, anemia, lethargy, poor appetite and weakness. Diagnosis There are two methods commonly used for X-ray examination H, mammography and dry plate photography. In addition, breast ultrasonography, which can reveal irregular mass shadows; LCD and infrared thermography, which can reveal high-temperature areas of masses with abnormal vascular images. Treatment Surgical treatment should be considered for all those who can be surgically removed. For stage I and II cases, radical surgery should be performed, and for those who have no lymph node metastasis confirmed by postoperative pathology, endocrine therapy and herbal medicine can be used; for those who have axillary lymph node metastasis, radiotherapy or adjuvant chemotherapy should be performed after surgery, and endocrine therapy and herbal medicine should be used at the same time. For stage III patients, radical surgery should be strived for. For stage III patients who cannot undergo radical surgery or stage IV patients with distant metastasis, palliative surgery should be strived for. Endocrine therapy and chemotherapy should be given to stage IV patients with distant metastasis and advanced patients with recurrence of metastasis, together with traditional Chinese medicine and supportive therapy, and palliative resection or palliative radiotherapy is feasible for limited metastatic lesions. If preventable Self-prevention of breast cancer should try to avoid worrying and depression, prevent emotional changes, use psychotherapy to make yourself mentally stable and cheerful. For various diseases of the breast, we should actively prevent and treat them. Advise mothers to breastfeed themselves to prevent breast lesions. The woman should eat more vegetables, avoid eating female pork, old nest squash, and eat less raw onion and garlic. How to self-examine Breast self-examination is best arranged 3 to 7 days after the end of menstruation, because at this time the breasts are less engorged, softer and easier to feel for lumps. You should first look for bilateral breast symmetry, abnormal shape, inflammatory skin changes and cellulite-like edema, etc. Then check the right breast with your left hand and the left breast with your right hand. The order of touch is from the upper inner quadrant of the breast, followed by the lower inner quadrant, lower outer quadrant, upper outer quadrant, areola area, and finally the axillary area. You should not use your hands to grasp and squeeze the breast, otherwise you will easily mistake the normal breast tissue for a lump. Afterwards, squeeze the nipple with your fingers to see if there is any abnormal overflow. Finally, touch the lymph nodes in the armpit and clavicle area with the left and right hands to see if there is any enlargement and painful redness. If a lump of uneven tissue, lumpy or granular, with a sense of elasticity, ranging in size from a few millimeters to 1 centimeter, is touched during breast self-examination, it is probably a normal lobular lump, usually larger before menstruation and smaller after menstruation, sometimes with tenderness, and should not be taken as a tumor.
