Stomach Cancer


Stomach cancer (also called gastric cancer) is now much less common than it was around 30 years back. It usually affects men and is common among those people who are above the age of 55.
The organ that connects the duodenum and the oesophagus is the stomach. It plays a role in digesting the food eaten, absorbing the nutrients into the body. This is done by contracting the stomach muscles for breaking down solid food particles.


Types of Stomach Cancer

There are many kinds of stomach cancer, adenocarcinoma being the most common one. Lymphoma is a lesser common kind of stomach cancer. It occurs in the lymphatic tissue. Sarcoma is another type of stomach cancer, which grows in the connective tissues in the wall of the stomach. It is advised to diagnose and treat the condition as early as possible, as there are high chances of it spreading into the liver, pancreas and the gullet.

Due to this reason, in many cases the condition gets quite developed by the time it’s diagnosed and the treatment is started. It is essential to get the symptoms checked as early as possible.

Family history – a person is very likely to get stomach cancer if any close member of his/her family is affected with it.
Having any other type of cancer – cancer in other parts of the body like the gullet or the non-hodgkin’s lymphoma raise the risk of getting afflicted by stomach cancer.
Medical conditions – certain medical condition that may result in stomach cancer are:
