Who Gets Gastric Cancer?

Helicobacter pylori (H. pylori)

This bacteria which causes ulcers and inflammation in your stomach is one of the main causes of gastric cancer. There are different strains, some of which have a higher risk of cancer. The strain H. Pylori can be detected by running blood tests and can be treated with antibiotics, which may be another reason this kind of cancer is less common now than in the 1930s.

Medical History

A person’s chances of having stomach cancer may be higher if they or any member of their family has had a stomach surgery. A few medical conditions such as pernicious anemia – where you have low red blood cells, can raise your chances. Also, familial adenomatous polyposis – when you have polyps in your stomach and colon, can equally raise your chances of getting gastric cancer.

Food and habit that can increase your risk

Your everyday habits can affect your chances of getting gastric cancer. Eating a lot of smoked foods, salted fish and meat, and pickled vegetables can increase your risk, along with eating less fruit and vegetables. You also might be more likely to get it if you drink a lot of alcohol, smoke or are overweight/obese.

Diagnosis

Your doctor will want to know about your medical history and lifestyle, and also perform a physical exam. If gastric cancer is suspected, your doctor may suggest you see an gastroenterologist for tests.

Endoscopy

Your doctor will perform an endoscopy, where a tiny camera through a tube will be inserted down your throat to examine your stomach. If anything doesn’t look right, she’ll take a tiny piece of tissue called a biopsy, which will be processed in the lab, to check for cancer cells in the sample under a microscope.

Your doctor might suggest other ways to get a closer look at any tumor. This could be a CT (computerized tomography) scan, when several X-rays are taken from different angles and put together to make a more complete picture. Or you might have an MRI (magnetic resonance imaging) scan, which uses powerful magnets and radio waves to make detailed images

Surgery

Surgery may come into play depending on where your cancer is, how far it’s advanced. In most cases, surgery to take out the tumor is the first step. Your doctor also might remove part or all of your stomach or take lymph nodes from other parts of your body to check for signs showing if the cancer has spread.

Radiation and Chemotherapy

You also may have radiation therapy (high-powered X-rays) or chemotherapy (powerful drugs) to shrink the tumor before surgery is performed and possibly afterward as well to kill any remaining cancer cells. These two kinds of therapy are often used together.
