Why do Japanese get stomach cancer?

Many Asian countries, including Korea, Japan and China, experience disproportionately high rates of stomach cancer, possibly due to high rates of infection with Helicobacter pylori — also known as H. pylori — and the increased consumption of salted and smoked foods.

What blood type is less likely to get cancer?

Compared with blood type A, blood type B was associated with statistically significant reduced risk of all cancers (HR, 0.91, 95% CI:0.84, 0.99). Both blood types B and AB were associated with significantly lower risk of gastrointestinal cancer and colorectal cancer, respectively.

Is Menetrier’s disease premalignant?

Ménétrier disease is a rare, acquired, premalignant disease of the stomach characterized by massive gastric folds, excessive mucous production with resultant protein loss, and little or no acid production. The disorder is associated with excessive secretion of transforming growth factor alpha (TGF-α).

What causes Whipple disease?

Whipple disease is caused by a type of bacterium called Tropheryma whipplei. The bacteria affect the mucosal lining of your small intestine first, forming small sores (lesions) within the wall of the intestine. The bacteria also damage the fine, hairlike projections (villi) that line the small intestine.

Why does Menetrier disease cause protein loss?

Menetrier disease is a gastrointestinal condition characterized by overgrowth of the mucous cells (foveola) in the mucous membrane lining the stomach, causing enlarged gastric folds. This leads to excessive mucus production, causing protein loss from the stomach and low or absent levels of stomach acid.

How do you check for Whipple disease?

A DNA-based test known as polymerase chain reaction, which is available at some medical centers, can detect Tropheryma whipplei bacteria in biopsy specimens or spinal fluid samples. Blood tests. Your doctor may also order blood tests, such as a complete blood count.
