Gastric Cancer Causes
Gastric cancer is also recognized as stomach cancer. Gastric cancer may occur at different sites of the stomach. After diagnosis, if your doctor says that you are undergoing a stomach cancer, obviously you may wonder about your gastric cancer causes. Doctor seldom understands why this cancer develops in one person and not in other.
Majority (about 85 percent) of gastric cancer cases occurs in the inner lining of the stomach and is referred as adenocarcinoma. About 40 percent of cases develop in the lower part of the abdomen. At the onset, your gastric cancer may develop in the lining, further it may get metastasized in the nearby organs such as the small intestine and esophagus. In the later stages (phases for stomach cancer), it may extend towards the colon; liver and pancreas through the lymph nodes connecting them with the stomach. If it is not diagnosed in these stages, it may metastasize in other distant organs such as bones, lungs, ovaries etc.
Gastric cancer causes and risk factors:
There are some risk factors that may lead one to develop the gastric cancer. Your doctor may know that probably which factors may increase the possibility of developing cancer cells in a person. A risk factor can be a condition that increases the possibility of getting a disease. Here are some of the key risk factors that cause stomach cancer in a person.
Key causes of gastric cancer:
So far, there is no particular cause for the development of gastric cancer, but there are some factors that may increase the possibilities of gastric cancer. Some of the gastric cancer causes:
Exposure to certain elements such as molds, dusts, fumes and some other environmental agents in your workplace or home has been associated with the gastric cancer causes. Smoking may also elevate the risk of getting cancer.
Disorders and diseases:
Gastric cancer often starts to develop at a site where the lining of the stomach gets irritated or inflamed. However, many scientists claim that inflammation occurs due to the development of cancer and hence should not be considered as a cause. Some studies revealed that ulcers in the stomach are responsible for developing cancer conditions in the stomach. Stomach polyps are considered as the ancestors of cancer and are eliminated as a step of precaution. Risk of cancer depends on the types, number and size of the polyps.
Medical conditions that are responsible for the origin of cancer include:
Diet: Certain dietary factors increase the risk of developing cancer cells in the stomach. If these dietary factors are followed for a longer period, your chances of getting cancer are high. These dietary factors involve:
Many people who have these risk factors do not undergo gastric cancer; while on the other people develop this cancer without any risk factor. Though, there is no particular reason for the cancer development, still above mentioned gastric cancer causes contributes to the increasing possibilities.
