Dr Simon Vincent, director of research, services and influencing at Breast Cancer Now, said:
“We know that hormonal contraception can very slightly increase a woman's risk of developing breast cancer, and this study contributes to that existing evidence.
“However, the overall risk of developing the disease for women aged 49 and under remains small, regardless of whether or not they have the hormonal coil or take any other form of contraception, and for many women the benefits of using these contraceptives outweigh any risks.
"Women who are worried about breast cancer and contraception should talk to their doctor and anyone who wants more information or support can Breast Cancer Now’s specialist nurses on our free confidential helpline on 0808 800 6000.”
