Genetic testing is a medical test that looks for changes in chromosomes, genes or proteins that are linked to cancer and other diseases. Genes that are linked to cancer are sometimes called cancer genes. Some genes and genetic changes are also linked to inherited conditions called family cancer syndromes, which increase the risk of cancer.
