| colorectal cancer | <oncology> A malignancy that arises from the lining of either the colon or the rectum. Cancers of the large intestine are the second most common form of cancer found in males and females. Symptoms include rectal bleeding, occult blood in stools, bowel obstruction and weight loss. Treatment is based largely on the extent of cancer penetration into the intestinal wall. Surgical cures are possible if the malignancy is confined to the intestine. Risk can be reduced when following a diet which is low in fat and high in fibre. (27 Sep 1997) |

| pitch-worker's cancer | Carcinoma of the skin of the face or neck, arms and hands, or the scrotum, resulting from exposure to carcinogens in pitch, which occurs naturally as asphalt, or as a residue in the distillation of tar. (05 Mar 2000) |
| mouse cancer | Any of various types of malignant neoplasms that occur naturally in mice, especially in certain inbred "c. Strains" used for research studies. (05 Mar 2000) |
| mule-spinner's cancer | Carcinoma of the scrotum or adjacent skin exposed to oil, observed in some workers in cotton-spinning mills. (05 Mar 2000) |
| conjugal cancer | Cancer a deux occurring in husband and wife. Cancer a deux, carcinomas occurring at approximately the same time, or in fairly close succession, in two persons who live together. Origin: Fr. Deux, two (05 Mar 2000) |
| prostate cancer | The second most common malignancy in men. A malignant tumour of glandular origin in the prostate. Over 95% are adenocarcinomas. Most commonly seen in older men, with the age of 73 being the average age at the time of diagnosis. A family history for prostate cancer and perhaps, a diet that is high is fat are considered to be risk factors for this malignancy. Early detection is possible through annual digital rectal examinations and routine PSA testing. (27 Sep 1997) |
| scar cancer | <tumour> Carcinoma of the lung, usually adenocarcinoma, arising from a peripheral lung scar or associated with interstitial fibrosis in a honeycomb lung. Synonym: scar cancer. (05 Mar 2000) |
| scar cancer of the lungs | A pulmonary cancer intimately related to a localised area of parenchymal fibrosis; the cancer probably induces the fibrosis. (05 Mar 2000) |
| Schridde's cancer hairs | Thick lusterless hair's scattered in the beard and the temporal region, said to occur in cancerous patients but found also in persons with other cachectic conditions. (05 Mar 2000) |
| secondary lung cancer | The spread of cancerous tumours from a distant organ to the lung. Due to the lungs tremendous blood and lymphatic supply it is a frequent site for metastatic cancer. Cancers which commonly metastasize to the lung include osteosarcoma, breast cancer, neuroblastoma, Wilm's tumour and non-Hodgkin's lymphomas. (27 Sep 1997) |
| skin cancer | <oncology> A malignant growth on the skin. Risk factors include: those who are fair-skinned or sunburn easily, freckled skin, blue or green eyes, blond or red hair, multiple moles, multiple bad sunburns in the past (particularly as a child) and a prior history for a skin cancer. (27 Sep 1997) |
| small cell lung cancer | A type of lung cancer in which the cells are small and round. Also called oat cell lung cancer. (12 Dec 1998) |
| somatic mutation theory of cancer | That cancer is caused by a mutation or mutations in the body cells (as opposed to germ cells), especially nonlethal mutations associated with increased proliferation of the mutant cells. (05 Mar 2000) |
| spider cancer | An obsolete term for a malignant neoplasm with a rhizoid or filamentous edge of thin, threadlike, red lines that represent dilated vascular channels associated with the neoplasm; a form of telangiectatic cancer. (05 Mar 2000) |
| 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) |
