0 Stomach Cancer


DEFINITIONS
Benign tumors of the stomach seems to not cause symptoms or medical problems. But sometimes, some bleeding or develop into cancer.

Approximately 99% of gastric cancer is adenocarcinoma.
Other gastric cancer is leiomiosarkoma (cancer of smooth muscle) and lymphomas.

Kankler stomach is more common in the elderly.
Less than 25% of certain cancers occur in people under the age of 50 years.
In China, Japan, Chile and Iceland, so often found in gastric cancer.
In the U.S., more common in poor, black people and people living in the north. And is the No. 7 cause of death, which occurred at approximately 8 of every 100,000 people.

CAUSE
Gastric cancer often begins on the side where the inflamed stomach lining. But many experts believe that inflammation is a result of gastric cancer, not as a cause of cancer.
Some experts argue, gastric ulcers can cause cancer. But most people with ulcers and gastric cancer, the possibility is that cancer is not detected before tukaknya formed.

Helicobacter pylori, bacteria that play an important role in duodenal ulcer, could also play a role in the occurrence of gastric cancer.

Gastric polyp, a benign growth of the round, which grew into the cavity of the stomach, allegedly a sign of cancer and therefore always polyps removed.
Cancer may occur in conjunction with certain types of polyps, the polyps larger than 1.8 cm or polyps of more than one.

Specific dietary factors is estimated to play a role in gastric cancer growth.
These factors include:
- High salt intake
- High carbohydrate intake
- Intake of preservatives (nitrates) high
- Intake of green vegetables and fruits are lacking.
But none of those factors that have been proven to cause cancer.

SYMPTOMS
In early-stage gastric cancer, its symptoms are vague and often ignored.
If symptoms develop, can help determine where the location of gastric cancer. For example, full or uncomfortable feeling after eating can show the existence of cancer in the lower stomach.

Weight loss or fatigue usually caused by eating difficulties or inability to absorb some vitamins and minerals.

Anemia can be caused by bleeding in stages that do not cause other symptoms.
Sometimes patients may also experience a lot of vomiting blood (haematemesis) or issue a blackish stools (melena).

When gastric cancer grew, the mass may be palpable in the abdominal wall.

In the early stages, the small gastric tumors can spread (metastasize) to distant places.
The spread of tumors can cause liver enlargement, jaundice (jaundice), fluid collection in the abdomen (ascites) and skin nodules that are malignant.
The spread of cancer can also cause bone loss, resulting in broken bones.

DIAGNOSIS
Stomach cancer symptoms can be confused with peptic ulcers.
If symptoms do not disappear after patients taking medicine for ulcers or when symptoms include weight loss, then the suspicion of a gastric cancer.

X-ray examination using barium to mark a change in the surface of the stomach is often done, but rarely find a small gastric cancer in early stages.

Endoscopy is a diagnostic procedure is best because:
- Allows doctors to see directly the stomach
- Could find the existence of Helicobacter pylori, bacteria that play a role in gastric cancer
- Can take a sample of tissue for microscopic examination.

TREATMENT
Benign gastric polyps removed using endoscopy.

When carcinoma is found in the stomach, surgery is usually performed to try to cure him.
Most or all of the stomach and nearby lymph nodes involved was appointed.

If the carcinoma has spread to the outside of the hull, the goal of treatment is to reduce symptoms and prolong life expectancy.
Chemotherapy and radiation therapy can relieve symptoms.
Results of chemotherapy and radiation therapy in lymphoma better than carcinoma. Perhaps patients will survive longer can even cured.
