Major cancer breakthrough for women if they take this one pill
Scientists have discovered that a form of morning after pill could prevent young women getting breast cancer.
The pill, currently offered for free on the NHS, blocks the effects of the hormone progesterone and was shown to cause changes in breast tissue which can help prevent cancer developing there. A young woman who opted to have a double mastectomy as a preventative measure says the discovery “offers hope” to others at high genetic risk from the disease.
A Manchester University trial of 24 women at high genetic risk due to a family history of breast cancer took ulipristal acetate between 2016 and 2019. The women, aged 34 to 44, saw their breasts become less dense and stiff - which is known to make the environment less favourable for cancers to grow.

Lead author Dr Sacha Howell, of Manchester University and Consultant Oncologist at specialist cancer hospital The Christie, said: “We are profoundly grateful to the women who volunteered for this study. Our research, with them, provides evidence that progesterone plays a critical role in breast cancer development in high-risk individuals. By targeting its action, ulipristal acetate and other anti-progestins show promise as preventive treatments for women at increased risk.”
The breakthrough suggests repurposing ulipristal acetate for breast cancer prevention may reduce the risk of it developing in at-risk women before the menopause. Currently such women have only two options to reduce their risk.
One is long term hormone therapy which can come with side effects such as increased blood clotting risk and loss of bone density. The second option is preventative surgery to remove some or all of the breasts.
Grace Burton, aged 27, underwent a preventative double mastectomy last year after finding out she was at high risk of breast cancer due to an inherited BRCA1 gene change at the age of 21. Grace, from Bromley, south London, said: “Breast cancer has had a huge impact on my family - both my mum and my aunt were diagnosed, and knowing I was at high risk was always in the back of my mind.
"Having later gone through preventative surgery myself, I know how heavy and difficult those decisions can feel. That’s why this new research into preventative medication is so exciting, it offers hope for other women who might one day have less invasive options to protect their health.
“For those of us with a strong family history, the possibility of preventing breast cancer before it starts is incredible. It gives me hope that future generations may not have to make the same tough choices and can grow up with more options and less fear around breast cancer.”
