Indentation can gradually return to normal after mastectomy of a breast nodule. The cavity will be left after the breast nodule is removed, and the indentation will appear after the pressure bandage. This is because the blood vessels and fibrous tissues around the nodule will self-repair through proliferation after the removal of the nodule and form a scar, resulting in indentation and hardening of varying degrees. In most cases, the scar will gradually soften and return to normal within six months. If the lump is particularly large and superficial, a large cavity will remain after excision, and there may be a small amount of oozing in the middle of the cavity at an early stage, but the patient does not have to worry about it, as the normal tissues will gradually fill up the cavity, and most of them will return to normal within one year. After mastectomy, patients should pay attention to keep the incision site clean and clean, and pay attention to its changes. Avoid excessive fatigue in life, combine work and rest with appropriate activities, and maintain emotional stability. After mastectomy, the dimples can gradually return to normal, patients do not need to worry too much, and should be regularly rechecked. If there is any discomfort during the recovery process, consult a doctor in time to avoid delaying the condition.
