Question

The causes of gastrointestinal cancer mutation are unclear, however identify and discuss three predisposing factors.

Answer 1

Gastrointestinal cancer is the cancer cells develop in the inner lining of the stomach. The exact cause is unknown. But studies show that chronic inflammation, H.pylori infection, and pernicious anemia increases the risk of gastrointestinal cancer mutation. The predisposing factor that causes gastrointestinal cancer include

Age: People more than 50 years of age are more risk for gastrointestinal cancer as the age increases results in poor function of the gastrointestinal system.

Diet: People who ate an excessive amount of smoked foods, salted fish, meat products, are an increased chance of having Gastrointestinal cancer. Because these food substances contain nitrates which are converted by bacteria and leads to gastrointestinal cancer.

Gastro surgery: Patient who undergone previous gastro surgery are more prone to get of cancer. The reason is the stomach produces less amount of Hcl which allows the nitrate-containing bacteria into the intestine and further reflux of bile from the intestine into the stomach increases the risk factor.
