Stomach cancer surgery is a surgical intervention performed with the aim of removing or controlling cancerous tissue in the stomach region. The type of surgery is determined based on the stage of cancer, its location, and the overall health of the patient. A procedure called gastrectomy is commonly used, where either the entire stomach or the affected portion is removed, and sometimes surrounding lymph nodes are also taken out. In some cases, stomach cancer surgery can be done with a stomach-preserving procedure, where only the tumor and its immediate surroundings are removed. In the post-operative period, patients may need to make changes in their diet and lifestyle. Stomach cancer surgery is a step towards eliminating cancerous cells and improving the overall health of patients. It is performed by a specialist surgeon, and other stages of treatment, such as chemotherapy or radiotherapy, may be used additionally when necessary. It is important for patients to follow their doctor’s instructions both before and after the surgery.
