In response to research published in BMJ Medicine*, Dr Kotryna Temcinaite, head of research communications at Breast Cancer Now, said:
“This research shows that polygenic risk score tests alone do not accurately predict breast cancer risk. We know many different factors contribute to the chance of developing the disease, including family history and lifestyle. So, when combined with other ways to assess breast cancer risk, this kind of testing can add crucial information and lead to more reliable results.
“We encourage women to attend breast screening appointments when invited and to regularly check their breasts. Most breast changes, including lumps, won’t be cancer, but it’s important to contact a GP as soon as possible if you notice a change to your breast that’s new or unusual for you. The sooner breast cancer is found, the more successful treatment is likely to be. Anyone affected by breast cancer can speak to Breast Cancer Now’s expert nurses by calling our free helpline on 0808 800 6000 for information and support.”
