Cancer surgery is one of the common methods used in diagnosing and treating cancer. Surgery is often combined with other methods such as chemotherapy, radiation therapy, and more. The choice of the most suitable treatment methods depends on the type and stage of cancer, as well as the patient’s overall health. The goal of cancer surgery is to remove all of the cancer from the body whenever possible. To achieve this, the surgeon removes the cancer and some surrounding healthy tissue. The surgeon may also remove some lymph nodes from the same area. These lymph nodes are examined to check for cancerous cells. If the cancer has reached them, it is likely that the cancer has spread to other parts of the body.
