| telangiectasia, hereditary haemorrhagic | An autosomal dominant vascular anomaly characterised by the presence of multiple small telangiectases of the skin, mucous membranes, gastrointestinal tract, and other organs, associated with recurrent episodes of bleeding from affected sites and gross or occult melena. (12 Dec 1998) |

| elliptocytosis, hereditary | An intrinsic defect of erythrocytes inherited as an autosomal dominant trait. The erythrocytes assume an oval or elliptical shape. (12 Dec 1998) |
| exostoses, multiple hereditary | Hereditary disorder transmitted by an autosomal dominant gene and characterised by multiple exostoses (multiple osteochondromas) near the ends of long bones. The genetic abnormality results in a defect in the osteoclastic activity at the metaphyseal ends of the bone during the remodeling process in childhood or early adolescence. The metaphyses develop benign, bony outgrowths often capped by cartilage. A small number undergo neoplastic transformation. (12 Dec 1998) |
| eye diseases, hereditary | Transmission of gene defects or chromosomal aberrations/abnormalities which are expressed in extreme variation in the structure or function of the eye. These may be evident at birth, but may be manifested later with progression of the disorder. (12 Dec 1998) |
| Leber's hereditary optic atrophy | Hereditary degeneration of the optic nerve and papillomacular bundle with resulting rapid loss of central vision, progressive for several weeks, then usually stationary with permanent central scotoma; age of onset is variable, most often in the third decade; more males than females are affected and transmission is cytoplasmic and strictly on the female side. Mutation on the mitochondrial chromosome involved, which presumably interacts with an X-linked mutant. This mechanism may explain the bizarre sex ratio, which differs significantly from one country to another. (05 Mar 2000) |

| bladder cancer | The most common warning sign of bladder cancer is blood in the urine. The diagnosis of bladder cancer is supported by findings in the medical history and examination, blood, urine, and X-ray tests, and confirmed with a biopsy (usually during a cystoscope exam). Treatment of bladder cancer depends on the growth, size, and location of the tumour. (12 Dec 1998) |
| bladder cancer risks | Smoking is a major risk factor. Cigarette smokers develop bladder cancer 2-3 times more often than do nonsmokers. Quitting smoking reduces the risk of bladder cancer, lung cancer, several other types of cancer, and a number of other diseases as well. Workers in some occupations are at higher risk of developing bladder cancer because of exposure to carcinogens (cancer-causing substances) in the workplace. These workers include people in the rubber, chemical, and leather industries, as well as hairstylists, machinists, metal workers, printers, painters, textile workers, and truck drivers. (12 Dec 1998) |
| bone cancer | <oncology> A general term to imply malignant tumour growth in bone. (27 Sep 1997) |
| bovine cancer eye | A malignant squamous cell carcinoma of cattle, especially the Hereford breed, that originates in the conjunctival mucous membranes or the surrounding skin; it occurs principally in range cattle having unpigmented skin around the eye and living in regions of intense sunlight. (05 Mar 2000) |
| BRCA1 breast cancer susceptibility gene | This mutated (changed) version of the BRCA1 gene makes a person susceptible to developing breast cancer. (12 Dec 1998) |
| breast cancer | <oncology> The uncontrolled growth of malignant breast tissue. Breast cancer is currently the most common cancer in women and the leading cause of cancer-related death in the 15-54 age group. Strong risk factors include a prior history for breast cancer or a positive family history for breast cancer. Early detection is possible through the use of monthly breast self-examination, annual clinical exams and mammography.

| breast cancer susceptibility genes | Inherited factors that predispose to breast cancer. Put otherwise, these genes make one more susceptible to the disease and so increase the risk of developing breast cancer. Two of these genes, BRCA1 and BRCA2, have been identified (and prominently publicised). Several other genes (those for the Li-Fraumeni syndrome, Cowden disease, Muir-Torre syndrome, and ataxia-telangiectasia) are also known to predispose to breast cancer. However, since all of these known breast cancer susceptibility genes together do not account for more than a minor fraction (1/5th at most) of breast cancer that clusters in families, it is clear that more breast cancer genes remain to be discovered.

| buyo cheek cancer | betel cancer |
| cancer | <oncology> The first historical description of this condition was in relation to breast carcinoma. This is now a general term for more than 100 diseases that are characterised by uncontrolled, abnormal growth of cells. Cancer cells can spread locally or through the bloodstream and lymphatic system to other parts of the body. (18 Nov 1997) |
