Types Of Stomach Cancer

Adenocarcinomas

About 90 to 95% of stomach cancers are adenocarcinomas. Most of the time, these type of cancers develops from your gland cells in the innermost lining of your stomach. If your doctor says that you have gastric or stomach cancer, it will be adenocarcinoma.

Moreover, other types of cancer may begin in your stomach, such as neuroendocrine tumors, gastrointestinal stromal tumors (GISTs), and Lymphomas. 

Neuroendocrine tumors involving carcinoids

Neuroendocrine tumors start in cells in your stomach and other organ or parts of the digestive tract, this may act like nerve cells in various ways and like hormone-making cells.

It is essential to know that survival rates are estimated and based on previous results. The relative survival rates have been shown below in three groups such as:

  • 1. The number of people found with cancer with no sign that cancer has been developed or spread outside your stomach is about 70%. 
  • 2. When cancer has been developed or grown over the stomach’s outer layer to near lymph nodes or structures, the survival rate is around 32%. 
  • 3. If cancer has spread to different parts of your body, like the liver, the survival rate is about 6%.
