Mutations can be transmitted through either the maternal or paternal line. It is known that about 5\u201310% of all cancers are linked to hereditary factors<\/strong>.<\/p>\n Breast cancer<\/strong><\/p>\n<\/li>\n Ovarian cancer<\/strong><\/p>\n<\/li>\n Prostate cancer<\/strong><\/p>\n<\/li>\n Colorectal cancer (colon and rectum)<\/strong><\/p>\n<\/li>\n Melanoma<\/strong><\/a><\/p>\n<\/li>\n Pancreatic cancer<\/strong><\/p>\n<\/li>\n Medullary thyroid cancer<\/a><\/strong><\/p>\n<\/li>\n<\/ul>\n Mutations in genes <\/a>BRCA1, BRCA2<\/a>, TP53, MLH1, MSH2, APC<\/strong> and others significantly increase the risks. For example, women with the BRCA1 mutation have up to a 70% risk of developing breast cancer by age 70.<\/p>\n There are several signs that prompt a doctor or genetic counselor to refer you for testing:<\/p>\n Oncology in 2\u20133 generations in a row<\/strong><\/p>\n<\/li>\n Cancer cases under the age of 50 years or younger<\/strong><\/p>\n<\/li>\n One person has several types of tumors<\/strong><\/p>\n<\/li>\n Were bilateral tumors<\/strong> (for example, in both breasts)<\/p>\n<\/li>\n There were both female and male oncological diagnoses of the same type in the family (for example, breast cancer in a man)<\/p>\n<\/li>\n<\/ul>\n The most informative way is genetic blood test<\/strong> or a cheek swab. It determines whether a patient has specific mutations associated with cancer risk.<\/p>\n Before the test, a consultation with a geneticist is mandatory. After - a discussion of the results and a strategy of action:<\/p>\n observation<\/p>\n<\/li>\n more frequent examinations (ultrasound, mammography, colonoscopy)<\/p>\n<\/li>\n prophylactic removal of an organ (in rare cases)<\/p>\n<\/li>\n informing relatives<\/p>\n<\/li>\n<\/ul>\n A positive genetic test result does not mean that you will definitely get the disease. It a signal that it is worth acting proactively<\/strong>:<\/p>\n don't ignore symptoms<\/p>\n<\/li>\n undergo routine examinations<\/p>\n<\/li>\n change lifestyle (quitting smoking, diet, exercise)<\/p>\n<\/li>\n be in touch with a specialist<\/p>\n<\/li>\n<\/ul>\n Early risk identification enables detect cancer early or even prevent its development<\/strong>. Sometimes this allows you to avoid difficult treatment in the future. Thanks to the development of medical technology, the possibilities of early diagnosis are constantly improving, which gives doctors more tools to monitor the health of patients. Topic \u201ctumor markers and cancer: what you need to know\u201d<\/a> should be considered an important aspect of detecting the disease in its early stages.
