The new mammogram guidelines put out by the American Cancer Society are being met with some mixed opinions.

The American Cancer Society is now recommending that women wait until age 45 to get their first mammogram. Women were previously urged to get their first mammogram at 40.

Kathy Ann Sirico says she never misses her yearly mammogram. She disagrees with the new guidelines even though she has never had breast cancer.

Dr. Maureen Killackey, who heads the cancer center at NY Presbyterian Lawrence Hospital in Bronxville, says she has been hearing a lot of thoughts from women on the matter. She says medical evidence supports the new age requirement. Dr. Killackey says about 90 percent of breast cancers occur from the age of 45 and later.

Dr. Killackey does point out that the new guidelines don't mean women shouldn't have mammograms sooner. She says women should just be informed and discuss their concerns with their doctor.
