Are most cancers hereditary?

Although cancer is common, only 5-10% of it is hereditary, meaning an individual has inherited an increased risk for cancer from one of their parents.

Results. The most common sites of metastasis were liver (in 48% of metastatic cancer patients), peritoneum (32%), lung (15%), and bone (12%). Metastases to the lung, nervous system, and bone were more frequent in cardia cancer and men, whereas non-cardia cancer more frequently metastasized within the peritoneum.

What foods fight stomach cancer?

Citrus fruits, such as oranges, lemons and grapefruit, which contain both vitamin C (which can neutralize cancer-causing free radicals) and flavonoids (which can inhibit cancerous cells from invading healthy tissues) Carrots and sweet potatoes, which contain beta-carotene, a powerful antioxidant.

How does chronic atrophic gastritis cause stomach cancer?

People with this condition usually have chronic atrophic gastritis as well. How and why this change occurs and progresses to stomach cancer is not well understood. This might also be related to H pylori infection. Recent research has provided clues on how some stomach cancers form.

Is the incidence of gastric cancer on the rise?

Although the incidence of gastric cancer has gradually decreased over the last half century, cancer at proximal stomach is on the rise ( 3, 4 ). Today, gastric cancer is still the seventh most common cause of cancer-related death in the United States ( 5) and the prognosis of advanced gastric cancer remains poor.

How does smoking increase the risk of stomach cancer?

Smoking increases stomach cancer risk, particularly for cancers of the upper part of the stomach near the esophagus. The rate of stomach cancer is about doubled in people who smoke. Stomach cancers are more likely to develop in people who have had part of their stomach removed to treat non-cancerous diseases such as ulcers.
