Stomach cancer, also known as gastric cancer, is a tumor originating in the cells of the stomach. It occurs when the healthy cells lining the stomach walls grow out of control and become cancerous, forming a tumor. The different types of stomach cancer are:


  • Adenocarcinoma: This is the most common type of stomach cancer where the tumor starts in the gland cells in the inner lining of the stomach.
  • Carcinoid Cancer:This begins in the hormone-producing cells of the stomach.
  • Lymphoma:This affects the body’s immune system.
  • Gastro-intestinal Stromal Cancer (GIST): This originates in specific cells of the nervous system.

Treatment Overview


Gastro-intestinal cancers are complex diseases as they behave differently in different people. Therefore, a personalized treatment plan is necessary for each patient. The common options for gastric cancer treatment include surgery, radiation therapy, chemotherapy, immunotherapy and targeted therapy.


  • Surgery: It is very common during the treatment of gastric cancer. It involves removal of a part of the stomach containing the tumor and the surrounding lymph nodes and healthy tissue. This procedure is known as gastrectomy.


  • Radiation Therapy: High-energy X-rays are used to destroy the cancer cells and alleviate some of the symptoms associated with gastric cancer.


  • Chemotherapy: A medical oncologist administers drugs to end the ability of the cancer cells to multiply.


  • Immunotherapy: The body’s natural defence system is strengthened to enable it to fight the cancer effectively.


  • Targeted Therapy: It is a treatment that targets the specific genes, proteins and the tissues that aid in the spread and survival of cancer.


  • Palliative Care: Such treatments are intended to reduce the pain in patients with extremely advanced cancers.
