| stomach cancer | Cancer of the major organ that holds food for digestion. Stomach cancer (gastric cancer) can develop in any part of the stomach and spread to other organs. Stomach ulcers do not appear to increase a person's risk of developing stomach cancer. Symptoms of stomach cancer are often vague, such as loss of appetite and weight. The cancer is diagnosed with a biopsy of stomach tissue during a procedure. (12 Dec 1998) |
| stomach cancer-associated protein-tyrosine phosphatase | <enzyme> Human transmembrane-type ptpase expressed in gastric, pancreatic and colourectal cancer cells; consists of 1093 amino acid; mw 200 kD; genbank d15049 Registry number: EC 3.1.3.- Synonym: sap 1 phosphatase (26 Jun 1999) |
| stump cancer | Carcinoma of the stomach developing after gastroenterostomy or gastric resection for benign disease. (05 Mar 2000) |

The risk of cancer of the oesophagus is increased by long-term irritation of the oesophagus such as with smoking, heavy alcohol intake, and Barrett's oesophagitis. Cancer of the oesophagus can cause difficulty and pain with swallowing solid food. Diagnosis of oesophageal cancer can be made by barium X-ray of the oesophagus, and confirmed by endoscopy with biopsy of the cancer tissue. (12 Dec 1998) |
