2- Let parents change their life style to increase the child's life span.

3- Clarify your cancer risk.

4- Explains why you or other family members have developed cancer.

5- If you have a genetic abnormality that you don't want to pass on to children, getting tested (both you and your partner) will let you make informed decisions.
