STOMACH CANCER – CAUSES & SYMPTOMS
Stomach cancer (gastric cancer) starts when cancer cells exist in the inner lining of your stomach. These cells can develop into a growth (tumor). The disease usually takes several years to grow. If the signs of this cancer are detected early, it can be easily treated.
Causes
1. Infections with a common bacteria, H. pylori, which causes ulcers, inflammation in the gut called gastritis, long-lasting anemia, and growths in your stomach called polyps.
2. Smoking
3. Being overweight or obese
4. A diet high in smoked, pickled, or salty foods
5. Stomach surgery for an ulcer
6. Type-A blood
7. Epstein-Barr virus infection
8. Certain genes
9. Working in coal, metal, timber, or rubber industries
10. Exposure to asbestos

Symptoms
1. Indigestion
2. Feeling bloated after meal
3. Heartburn
4. Slight nausea
5. Loss of appetite

As stomach tumors grow, you may have more serious symptoms, such as:
1. Stomach pain
2. Blood in your stool
3. Vomiting
4. Weight loss for no reason
5. Trouble swallowing
6. Yellowish eyes or skin
7. Swelling in your stomach
8. Constipation or diarrhea
9. Weakness or feeling tired
10. Heartburn

Diagnosis
Your doctor will give you a physical exam. He’ll also ask about your medical history to see if you have any risk factors for stomach cancer or any family members who’ve had it. Then, he might give you some tests, including:
1. Blood tests to look for signs of cancer in your body.
2. Upper endoscopy. Your doctor will put a thin, flexible tube with a small camera down your throat to look into your stomach.
3. Upper GI series test. You’ll drink a chalky liquid with a substance called barium. The fluid coats your stomach and makes it show up more clearly on X-rays.
4. CT scan . This is a powerful X-ray that makes detailed pictures of the inside of your body.
5. Biopsy . Your doctor takes a small piece of tissue from your stomach to look at under a microscope for signs of cancer cells. He might do this during an endoscopy.
