Stomach Cancer By: Kimberly Rosales & Laura Zuniga Per. 5
What is stomach cancer? n Stomach cancer, also called gastric cancer, is a malignant tumor arising from the lining of the stomach.
What causes stomach cancer? n n n n The exact cause of stomach cancer is unknown, but a number of factors can increase the risk of the disease, including: Gender -- men have more than double the risk of getting stomach cancer than women. Race -- being African-American or Asian may increase your risk. Genetics -- genetic abnormalities and some inherited cancer syndromes may increase your risk Blood type -- individuals with blood group A may be at increased risk. Advanced age -- stomach cancer occurs more often around ages 70 and 74 in men and women, respectively. Family history of gastric cancer can double or triple the risk of stomach cancer. Lifestyle factors such as smoking, drinking alcohol, and eating a diet low in fruits and vegetables or high in salted, smoked, or nitrate-preserved foods may increase your risk
Symptoms: n In the early stages of stomach cancer, you may have very few symptoms. These may include: n n Indigestion and stomach discomfort A bloated feeling after eating Mild nausea Loss of appetite Heartburn n In more advanced cancer, you may have: n Discomfort in the upper or middle part of the abdomen. Blood in the stool (which appears as black, tarry stools). Vomiting or vomiting blood. Weight loss. Pain or bloating in the stomach after eating. Weakness or fatigue associated with mild anemia (a deficiency in red blood cells). n n n n
Diagnose: n n n Your health care provider can often detect advanced stomach cancer by performing a physical exam. However, if you are having vague symptoms, such as indigestion, weight loss, nausea, and loss of appetite, screening tests may be recommended. These tests may include: Upper GI series. These are X-rays of the esophagus, stomach, and first part of the intestine taken after you drink a barium solution. The barium outlines the stomach on the X-ray, which helps the doctor, using special imaging equipment, to find tumors or other abnormal areas. Gastroscopy and biopsy. This test examines the esophagus and stomach using a thin, lighted tube called a gastroscope, which is passed through the mouth to the stomach. Once stomach cancer is diagnosed, more tests may be done to determine if the cancer has spread. These tests may include CT scans, PET scans, bone scans, laparoscopy and endoscopic ultrasound.
Stomach cancer may often be cured if it is found and treated at an early stage. Unfortunately, the outlook is poor if the cancer is already at an advanced stage when discovered. In most cases, stomach cancer is found at later stages.
Treatments: n n Stomach cancer may be treated with the following, in combination, or alone: Surgery, called gastrectomy, to remove all or part of the stomach, as well as some of the tissue surrounding the stomach. Chemotherapy. Radiation therapy.
