CHICAGO | Women are going for breast cancer gene testing in record numbers, forcing more parents to face a tough question - should we test the children?

About 100,000 tests for breast cancer gene mutations were performed last year, double the number in 2005. The trend may grow even more because of widening insurance coverage and a new law banning genetic discrimination.

Medical professionals advise against such testing before age 25, saying little can be done to prevent or screen for breast or ovarian cancer until then, so the knowledge would only cause needless worry.

However, new studies and interviews by the Associated Press show that many people who have BRCA gene mutations - and even more of their offspring - disagree.

Cornell University freshman Jenna Stoller is one.

"I'm the kind of person that, like my mom, am more comfortable knowing something about myself than not knowing," said Miss Stoller, who tested positive earlier this year, shortly after her 18th birthday. Her mother made her wait five years after revealing her own positive test result, even though Miss Stoller wanted to be tested at age 13.

"I remember thinking on my 17th birthday that I had another year to wait till I could make the decision for myself," she said.

Research shows there can be benefits to at least talking about testing and inherited cancer risks with teens. It led some to quit smoking, one study found.

Others were advised to limit alcohol and avoid birth control pills, which can raise the risk of breast cancer though they also lower the risk of ovarian cancer.

A decade after BRCA testing began, researchers are just starting to discover the many effects that someone's positive test can have on other family members. A big issue is whether it is ethical or good to test minors.
