"People

tend to focus on the parent who is the same gender as they are. Women

look at their mom's side for breast cancer and men look at their dad's

side for prostate cancer, but this is missing half the story," she

said.

About 10 percent

of all cancers are in people who have inherited a predisposition to cancer.

Genetics counselors assess those who might have an increased risk of cancer

because of family history.

"Even

if there is a history of cancer in your family, that does not necessarily

mean you will develop the disease," Plon said. "But, it's important

to determine if you are at an increased risk and may need early screening."

Families with

a genetic susceptibility to cancer may have:

Multiple family

members with the same cancers.

Family members

who develop cancer at an unusually young age.

Family members

who develop a second or third "new" cancer.

Family members

with certain rare cancers, such as male breast cancer.

Plon said those

who are concerned about an increased risk of cancer should discuss the

issue with their primary care physicians. If a genetic evaluation is recommended,

the individual will be provided a risk assessment, as well as suggestions

for prevention, early detection and treatment options.
