You should talk to a genetic counselor. They can assess your risk based on your family’s cancer history and might suggest genetic testing. They can identify specific gene mutations like BRCA1, BRCA2, or others, that might have increased your family's risk of developing certain cancers.

Just to point out and partly answer one of your inquiries, there are specific genes that are linked to cancer, but it's usually the mutations which lead to cancer. And these mutations are lot of times related to the environment, and sometimes to other illnesses. And in most instances, it is several mutations over time not just one mutation or gene..Which is why you need proper genetic profiling and then adjust your life to decrease the risk, and for early detection by knowing what to get screened /assessed for regularly .
