Lymphedema is triggered by different causes, some of which can be cured and some of which cannot. For example, lymphedema caused by local soft tissue injury can be cured. Lymphoedema caused by tumor cells invading lymphatic vessels generally cannot be cured completely. 1. Local soft tissue injury: If there is local soft tissue injury, which leads to the leakage of lymphatic fluid after the breakage of capillary lymphatic vessels and constantly stimulates the local lymphatic tissues, it will cause lymphedema. It is recommended that under the guidance of professional doctors, appropriate ice compresses, combined with local pressure bandage, and anti-infection and edema-lowering treatments, such as amoxicillin, furosemide, etc., can cure lymphedema. 2. Tumor cells invade lymphatic vessels: if tumor cells invade lymphatic vessels, affecting the normal return of lymphatic fluid, it will cause lymphedema. This situation is more serious, even if timely surgical treatment, such as removing the primary tumor or clearing the lymph nodes, can not completely cure lymphedema. If lymphedema occurs, it is recommended to go to a regular hospital as soon as possible to find the cause as soon as possible, and take targeted treatment plan in time, so as not to delay the condition.
