'People need to be really careful. If a person’s goal is to find out about their hereditary cancer risk, they need to do testing in the right way.'
will cause many women to worry about their hereditary risk for developing the disease, especially if it runs in their family.
Genetic testing can answer that piece of the puzzle for breast and many other types of cancer, as well as a variety of diseases. It used to be costly, and require doctor’s orders and appointments. But anyone can now buy a fairly inexpensive DNA testing kit online and receive some answers without leaving home as part of a growing industry known as direct-to-consumer genetic testing.
Proponents say it democratizes the process, giving people more access to their genetic information and allowing them to take action to protect their health. But experts also worry about the tests’ validity and false reassurance, and a general lack of understanding about how much they can reveal. “Whenever a person is interested in their genetic background as it relates to health risk, it's a good thing. And if they pursue these direct-to-consumer tests, it's fine,” Leigha Senter, associate professor of human genetics at The Ohio State University College of Medicine and a licensed genetic counselor, told TODAY.
“People should take the extra steps, though, to make sure that their health care providers are aware of their results and that they understand the limitations that come along with doing a direct-to-consumer test because they're often not as comprehensive as the kind of cancer risk-related test that we might do in clinic.”
