I showed study Conducted by researchers at the Cancer Epidemiology Unit of the Department of Population Health at Oxford University, the use of progestogen-only hormonal contraceptives is associated with a 20-30 percent increased risk of breast cancer.
The website for the Department of Population Health said the use of progestogen-only contraceptives had increased dramatically in recent years, but information about their association with breast cancer risk was limited.
And in the study the study Publishing in the journal PLoS Medicine, the researchers analyzed data from 9,498 women who developed breast cancer between the ages of 20 to 49 and compared them to 18,171 women without the disease.
They found that taking the pill for five years increased a woman’s chance of developing breast cancer during the next 15 years by 20-30 percent, depending on her age at that time.
A reduced risk of breast cancer associated with oral contraceptive use was observed after use was discontinued.
The researchers said the risks were significantly higher for older women than for teenage girls.
Combined contraceptives are known to increase the risk of cancer, but the new study sheds light on the newer type of pill.
Study author Kirsten Berry said the risks and benefits of contraceptives must be weighed.
