Stomach Cancer Causes


Experts aren’t sure what causes stomach cancer. They presume there is a strong correlation between a diet high in smoked, salted and pickled foods and stomach cancer. As the use of refrigeration for preserving foods has increased around the world, the rates of stomach cancer have declined.

In general, cancer begins when an error (mutation) occurs in a cell’s DNA. The mutation causes the cell to grow and divide at a rapid rate and to continue living when normal cells would die. The accumulating cancerous cells form a tumor that can invade nearby structures. And cancer cells can break off from the tumor to spread throughout the body.

Several risk factors of developing stomach cancer are:

  • Helicobacter pylori infection
  • Diet that includes the following:
  1. large amounts of smoked foods
  2. salted fish and meat
  3. foods high in starch and low in fiber
  4. pickled vegetables
  5. foods and beverages that contain nitrates and nitrites
  • tobacco abuse
  • alcohol abuse
  • previous stomach surgery
  • megaloblastic (pernicious) anemia (caused by vitamin B12 deficiency)
  • Menetrier’s disease
  • age 55 or older (most patients are in their 60s or 70s)
  • male gender (more men are diagnosed with the disease than women)
  • having blood type A
  • family history of nonpolyposis colon cancer, familial adenomatous polyposis, or stomach cancer
  • history of stomach polyps
  • exposure to environmental factors such as dusts and fumes in the workplace
