Cancer is preventable and treatable with early diagnosis. Although cancer is mostly the result of mutations that accumulate over a lifetime, a significant proportion of it is inherited. This means that if a blood relative has cancer, you may be a carrier. To find out this risk, it is possible to examine cancer risk genes identified in scientific articles and medical protocols. With the new generation sequencing technology of familial cancer screening, a tube of blood is enough to get this information. Hereditary Cancer Panels are used for this process.
