After breast nodule surgery, patients with benign breast nodules need to rest for about 1 week after surgery, and patients with malignant breast nodules need to rest for 4 to 6 weeks. The details are analyzed as follows: 1. Benign breast nodule: it usually shows clear boundary, regular shape and good mobility. This kind of breast nodule can be treated by ultrasound-guided minimally invasive rotational excision or open surgery, and usually 1 week of rest is enough. 2. Malignant breast nodule: usually with blurred boundary, irregular shape, poor mobility and signs of lymphatic metastasis. If this kind of breast nodule meets the indications of surgery, it is usually necessary to take modified radical mastectomy for breast cancer, and the wound is large after surgery. If lymphatic metastasis is present, lymphatic dissection should be performed at the same time, and patients usually need to rest for at least 4 to 6 weeks after surgery. After breast nodule surgery, patients are advised to take more rest, do not do heavy physical labor, eat a light, high protein, high vitamin-based diet, and develop good and healthy eating habits.
