Genetic testing for cancer is growing, both in the number of people receiving testing and the discovered mutations associated with cancer inheritance. Some cancers have been linked to certain genes including breast cancer, melanoma family, descendants of papillary renal carcinoma, neurofibromatosis. You can browse the official website to know more about hereditary cancer testing online.
Although genetic testing for cancer can indicate whether a person has a tendency towards a kind of cancer that does not mean that they will get cancer. Likewise, a negative outcome for the cancer-causing gene does not mean that a person will not get cancer, but only that their chances of getting cancer are the same as for the general population.
The process of genetic testing for cancer will include an initial interview with a medical geneticist, genetic counselor, or doctor will know your family history and other relevant information. They were then able to advise you about genetic testing and it will be up to you to decide whether you want to go ahead with the test (you should never feel pressured to have genetic testing).

After this interview has taken place and you have decided to go ahead with genetic testing for cancer of your DNA sample will be taken. This can be done through a swab of the inner cheek or through blood samples. The DNA samples will be sent to a laboratory that will analyze the samples for genes known to be associated with hereditary cancer and mutations such as BRCA1 and BRCA2.
After genetic testing for cancer has been done you will be given your results but it is important to remember what has been mentioned earlier, that a positive result does not automatically mean you will get cancer and negative results that you will not.
