| gene cluster | A set of closely related genes that code for the same or similar proteins and which are usuallygrouped together on the same chromosome. (09 Oct 1997) |
| cluster analysis | A set of statistical methods used to group variables or observations into strongly inter-related subgroups. In epidemiology, it may be used to analyze a closely grouped series of events or cases of disease or other health-related phenomenon with well-defined distribution patterns in relation to time or place or both.

| cluster of differentiation | Cell membrane molecules that are used to classify leukocytes into subsets. CD molecules are classified by monoclonal antibodies. (05 Mar 2000) |
| cluster of differentiation 2 | A glycoprotein that is expressed on all peripheral T-cells, large granular lymphocytes and most, but not all, thymocytes. CD2 is involved in signal transduction and cell adhesion. (05 Mar 2000) |
| cluster of differentiation 3 | A complex of 5 polypeptides associated with the T-cell receptor and is involved in signal transduction. (05 Mar 2000) |
| cluster of differentiation 4 | A glycoprotein found on various subsets of T-cells, i.e., usually no helper and some T cytotoxic cells. (05 Mar 2000) |
| cluster of differentiation 8 | Membrane glycoprotein found on subsets of T lymphocytes. CD8 is expressed on T cytotoxic cells and T suppressor cells. Acronym: CD (05 Mar 2000) |
| egg cluster | One of the clumps of cells resulting from the breaking up of the gonadal cords in the ovarian cortex; these clumps later develop into primary ovarian follicles. (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.
