Use of progestogen-only hormonal contraceptives is associated with a higher risk of breast cancer, a new study suggests
“Current or recent use of progestagen-only contraceptives is associated with a slight increase in breast cancer risk,” University of Oxford researchersHowever, they stress excess risks “must be viewed in the context of the well-established benefits of contraceptive use in women’s reproductive years”.
Claire Knight of Cancer Research UK, which funded the research, said: “Combined and progestogen-only hormonal contraception can increase the risk of breast cancer, but the risk is small. Their history was compared with a control group of 18,000 women of the same age and from the same GP practices who had not been diagnosed with the disease.The 25 per cent increase in risk equates to an extra 61 women aged 25-29 per 100,000 being diagnosed with breast cancer over a 15-year period. Among 35 to 39-year-olds, there was an excess risk of 265 women per 100,000 over the same timeframe.
She added: “Yes, there is an increase here, and yes, nobody wants to hear that something that they’re taking is going to increase their risk for breast cancer by 25 per cent.“We’ve known for many years that combined oral contraceptives, which women have been using for decades, also have an effect on breast cancer risk, a small increase in risk which is transient.
Although the findings provide evidence about the short-term associations between hormonal contraceptives and breast cancer risk, the researchers warn they do not provide information regarding longer-term associations, or the impact of total duration of contraceptive use on breast cancer risk.

Researchers identify the origin of subset of autoantibodies that worsen lupusIn an effort to understand the origin of systemic lupus erythematosus and why some patients present with more severe disease than others, Johns Hopkins Medicine researchers say they have identified a type of autoantibody that may worsen the condition and have also found how these autoantibodies originate. They say their findings have implications for biomarker testing in lupus and may help identify patients that need early and aggressive treatment.
