Great @ema1! I believe that the more we know about our bodies and our family medical history, the better we and our families will be.

Genetic testing is one of the ways we can do that. However, many don't want to know; others are concerned about finding out something may be wrong. Others will have the genetic test but may not want to share their information with family members.

Once a cancer is discovered, or when there is a history of one or more cancers in the family, I am in strong support of being tested. Should there be any genetic mutations of concern, the type of treatment may need to be changed; therefore, doing so before the surgery, in my view, is certainly best.
