Mastectomy wounds take about 2 to 4 weeks to heal, but the exact recovery time is related to a number of factors, such as the individual’s physical condition and post-operative care. Mastectomy is more traumatic to the breast tissue and requires a certain amount of time to recover. If an individual is in good physical condition and there is no fluid formation under the breast skin or other abnormalities after the surgery, he or she will be fine in about 2 to 3 weeks. If the individual is not in good health and there is fluid under the breast skin after surgery, or there is poor local healing and infection, the wound recovery time after mastectomy will be longer, perhaps 3~4 weeks or longer. Complications such as skin necrosis and localized accumulation of fluid may occur after mastectomy. After the surgery, you need to pay more attention to observing the condition of your breasts, and if there are any abnormalities, you need to go to the hospital in time for medical treatment.
