7 Healthcast: Birth Control Risks

A popular form of birth control has been shown to have some health risks.

Young women doubled their risk of heart attract or stroke if they used oral contraceptives with low dose estrogen and progesterone. Doctors say a risk of heart attack and stroke in a healthy young woman is low.

"With the current pills that are out there now, it's pretty safe," said Dr. Saul Jeck, a gynecologist, "As a doctor, I have to say, there's got to be risk with whatever you do."

The risks go up as the dose of estrogen increases and as a woman gets older. Birth control patches and vaginal rings were also linked to an increase in blood clots.
