mutation<\/strong>. When a gene undergoes a mutation (due to biological, chemical and physical causes), the cell will receive improper information about its function.<\/p>Tumors, for the most part, are\u00a0sporadic<\/strong>: the mutation develops randomly without a particular family predisposition. The mutation originates in the DNA of a small group of cells and determines a genetic error that will perpetuate in the descendants of those cells, which, accumulating in a specific organ, will initially replace the healthy tissue and then spread to nearby or distant organs ( metastases).<\/p>While in sporadic tumors, the genetic mutation is present only in the tumor cells, and therefore only in the area of the organ affected by the neoplasia, in the case of\u00a0hereditary tumors<\/strong>, the mutation is present in all the patient\u2019s cells. To demonstrate that the predisposition to the development of a tumor is hereditary and to be able to identify the associated DNA mutation provides the great advantage of\u00a0being able to predict<\/strong>\u00a0the evolution of the tumor in the affected subject and\u00a0to eliminate or reduce the risk<\/strong>\u00a0of cancer in relatives who are carriers of the mutation.<\/p>Gene alterations that may predispose to tumor development have been identified for some cancers\u00a0(breast, colon, stomach, kidney, melanoma, thyroid, pancreas, parathyroid and adrenal gland)<\/strong>\u00a0and many studies are underway for other types of cancer.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"Homepage For each cancer type, between 5 and 10% of cases are attributable to a hereditary form.
