One of the that cancer can be a serious disease is its ability to spread to other parts of the body beyond the location of the primary tumour. When cancer cells spread to distant lymph nodes, tissues or organs, it is called metastatic cancer
Gastric cancer is a disease in which cancer cells form in the lining of the stomach. Almost all gastric cancers are adenocarcinomas, a cancer that begins in glandular tissue. Gastric cancer is often in an advanced stage when it is diagnosed. At this stage, it can often be treated, but rarely cured.
