Pros & Cons of Genetic Testing
Genetic testing for cancer looks for specific inherited changes (mutations) in a person’s genes that are associated with a high-to-moderate increased risk of cancer. And while there are certainly benefits to being tested for these mutations, it is important to understand that there are also limitations. For example, a positive result from cancer genetic testing doesn’t necessarily mean that you will develop cancer but can weigh heavily on the minds of you or your loved ones. On the other hand, a negative result doesn’t guarantee that you won’t develop cancer.
