Beware ladies! Contraceptive pills may up the risk of breast cancer: Study

Contraceptive pills have always proved life saving when you didn't want to take risk but now you may need to avoid them as a new study warns that the use of contraceptive may up the risk of breast cancer than previously feared.

According to the researchers from the University of Michigan commonly prescribed birth control pills may increase tyhe levels of synthetic estrogen and progesterone hormones by four times.

Both the hormones stimulates the growth of breast cancers, which is the reason why some breast cancer patients are prescribed hormone therapy to block their effects on cancer cells.

The results revealed that there were much higher levels of hormones in the blood taken from women who used birth control pills compared to women who did not.

Four out of seven formulations tested were found to quadruple the levels of progestin, a synthetic version of the hormone progesterone. 

Another formulation also resulted in 40 percent higher exposure to ethinyl estradiol, synthetic version of estrogen.
