Reducing Cancer
| Term | Definition |
|---|---|
| Allele | Any of the alternative forms of a gene that may occur at a given locus. |
| BRCA | Either of two tumor suppressor genes that in mutated form tend to be associated with an increased risk of certain cancers and especially breast and ovarian cancer. |
| Cryosurgery | Surgery in which diseased or abnormal tissue is destroyed or removed by freezing (as by the use of liquid nitrogen) |
| Familial Cancer | Occurs in families more often than would be expected by chance. These cancers often occur at an early age, and may indicate the presence of a gene mutation that increases the risk of cancer. |
| Genetic Marker | Alteration in DNA that may indicate an increased risk of developing a specific disease or disorder. |
| Hereditary Cancer | A inherited disorder in which affected individuals have a higher-than-normal chance of developing certain types of cancer, often before the age of 50. |
| Marker Analysis | A genetic technique whereby the sequence of the gene in not directly analyzed, but the mutant copy (allele) of the gene is inferred through analysis of a genetic marker. |
| Microsatellites | Any of numerous short segments of DNA that are distributed throughout the genome, that consist of repeated sequences of usually two to five nucleotides often useful markers in studies of genetic linkage they tend to vary from one person to the next. |
| Melanoma | A tumor of high malignancy that starts in melanocytes of normal skin or moles and metastasizes rapidly and widely. |
| Model System | An organism chosen to study broad biological principles. |
| Screening | To test or examine for the presence of something (as a disease) |
| Sporadic Cancer | Cancer occurring occasionally, singly, or in scattered instances. |
| Virologist | A specialist, in the branch of science that deals with viruses. |
