New test for breast cancers may identify chance of relapse

Scientists have identified 11 different types of breast cancer and, by looking at genes in tumours, can now predict how likely breast cancer survivors are to relapse.

University of Cambridge and Stanford University researchers analysed the tumours of nearly 2000 breast cancer patients and tracked their health over 14 years to find there are 11 different types of breast cancer, all with separate risks of relapsing. They identified those likely to be cured and others whose cancer could return.

The new test could offer women peace of mind through predicting their risk of getting breast cancer again in the next 20 years.

Researchers say a simpler version could be available for doctors to use within five years.
