stomach cancer: This disease usually grows slowly over many years. The main cause is lifestyle.
Almost all stomach cancers (about 95%) begin in the glandular tissue that lines the stomach. The tumor may spread along the stomach wall or it may grow directly through the wall and shed cells into the bloodstream or lymphatic system. The cancer can spread to other organs.
Gastric cancer is classified according to the type of tissue from which the cancer cells begin.
– Adenocarcinomas are the most common type and begin in the gastric mucosa.
– Lymphomas develop from white blood cells, a type of blood cell involved in the immune system.
-Sarcomas involve connective tissue (muscle, fat, or blood vessels).
-Other types include carcinoid, small cell carcinoma, and squamous cell carcinoma.
Metastatic cancer from breast cancer, skin cancer, and other primary sites of cancer can also be seen in the stomach.

How to prevent stomach cancer?
Treat gastritis. If you have an ulcer caused by H. pylori infection, seek medical treatment. Antibiotics can kill the bacteria, and other medications treat the ulcers in your stomach lining to reduce your risk of cancer.
Eat healthy. Eat more fresh fruits and vegetables. These foods are high in fiber and contain certain vitamins that may reduce your risk of cancer. Avoid salty, pickled, cured, or smoked foods, such as hot dogs, processed meats, or smoked cheeses. Also, keep your weight in a healthy range. Being overweight or obese can increase your risk of disease.

Use aspirin or NSAIDs with caution. If you take aspirin daily to prevent heart problems or NSAIDs for arthritis, talk to your doctor about how these medications might affect your stomach.
Finally, if you are at high risk for this disease, talk to your doctor to find out what precautions you can take. To find out if you have stomach cancer, your doctor will start with a physical exam. They will also ask about your medical history to see if you have risk factors for stomach cancer or if there are any family members who have had it.
