Cancer surgery is a medical procedure aimed at removing cancerous tumors and surrounding tissue from the body. It is often one of the first treatments considered for various types of cancer, depending on the stage and location of the disease. The goal is to eliminate as much of the cancer as possible, which can help improve the chances of recovery. In some cases, cancer surgery may also involve removing nearby lymph nodes to check for the spread of cancer. This type of surgery can be performed using traditional open techniques or minimally invasive methods, such as laparoscopy, which uses small incisions and specialized instruments.
