Once breast cancer patients are diagnosed, they usually have to consider whether they want to do breast-conserving surgery or mastectomy. On the one hand, breast-conserving surgery is to preserve the beauty of women, but on the other hand, breast-conserving surgery is more prone to recurrence, while mastectomy is a simple and straightforward way to cut the tumor, thinking that there is nowhere to regenerate. What are the characteristics of these two surgical methods? 1. Breast-conserving surgery means removing the lump and part of the breast gland, but keeping the whole or most of the breast. Breast-conserving surgery is suitable for patients who have the will to preserve breast, the breast tumor can be removed completely, the tumor size is in the right proportion to the breast, and the pectoral muscle and skin are not invaded. Among them, there are many indications to be considered. In general, it means that the lump is smaller and isolated, the lump is far from the center such as areola, and the size of female breast is moderate. 2. Mastectomy, too, has different types of procedures. At present, the more used one is modified radical mastectomy for breast cancer, which means removing the breast (skin, subcutaneous tissue, breast gland and nipple-areola complex), clearing the axillary lymph nodes and removing the pectoralis major muscle fascia, but will preserve or partially preserve the pectoralis major and pectoralis minor muscles. In terms of treatment outcomes, the overall five-year survival rates for breast-conserving surgery and total excision are similar. However, the results of surgery without breast conservation are better than those of breast conservation surgery. The absolute recurrence rate of patients after breast-conserving surgery is a little higher compared to those without breast-conserving, about 2-5% higher. For patients with large preoperative lumps, metastatic lymph nodes, poor staging, and family history, the recurrence rate after breast-conserving surgery may be higher. What should I pay attention to after breast cancer surgery? Breast cancer is treated clinically by surgery; what should be paid attention to after breast cancer surgery? 1. After breast cancer surgery, you should keep your spirit happy and avoid emotional excitement or depression. 2. After breast cancer surgery, you should ensure sufficient sleep, do some activities within your ability and perform post-operative physical exercise. Patients should move the affected upper limb as soon as possible, choose to stand on the wall, hold the affected limb on the wall and climb up as much as possible, then gently press forward by weight, from light to heavy slowly. And massage the affected limb with the hand on the healthy side. When the function of the affected limb is restored, the patient should insist on strengthening the body with exercises such as tai chi. 3.After surgery, you should go to the hospital for regular review, once every quarter in the first year, once every six months in the second year, and once every year thereafter, and chemotherapy and endocrine therapy should be carried out as planned. 4.After breast cancer surgery, you should eat reasonably, mainly small amount and many meals, drink more water, which can relieve stomach discomfort, choose high-calorie, high-protein, high-fiber and easy-digestible food according to your preference, and avoid sweet, fried and high-fat diet.
