CLEVELAND -- Women who've had estrogen replacement therapy are at higher risk for uterine cancer.

Uterine cancer is one of the easiest cancers to find early, and is also one of the most common, according to health reporter Alicia Booth.

Booth said women who have already been through menopause should become educated about uterine cancer.

It's also important to know about uterine cancer if you've been on estrogen therapy because those people are at the highest risk of getting it.

When Marilyn Cook started going through menopause, she had all kinds of uncomfortable symptoms.

"You feel nervous, jittery for no reason, so you're willing to take something that might put you on track," said Cook, a cancer survivor.

For Cook, it was hormone replacement therapy, which is now linked to a higher risk of heart attack, stroke and breast cancer.

Cook, however, ended up with uterine cancer after years of estrogen therapy.

Dr. Vivian Von Gruenigen specializes in treating female reproductive cancers. She said 90 percent of her uterine cancer patients have bleeding as a warning sign.

"So that's why women who are on estrogen alone should receive an office endometrial biopsy," she said.
