Risk of certain breast cancers coming back remains for at least 20 years after treatment | New England Journal of Medicine | Story via Cancer Research UK
Research, carried out by The Early Breast Cancer Trialists’ Collaborative Group collected data from more than 60,000 women who had been diagnosed with hormone sensitive breast cancer (usually called oestrogen receptor positive or ER+ breast cancer) between 1976 and 2011.
All of the patients were given a type of anti-oestrogen therapy for five years as part of their treatment. At the five year mark the women had no signs that their breast cancer had come back and treatment ended.
The figures, published in the New England Journal of Medicine show that out of the women included in the study, 11,000 had their cancer come back in another part of the body such as the bone, liver and lung in the 15 years after stopping treatment. They also showed that the risk of cancer coming back remained the same year on year from when they stopped taking the anti-oestrogen drugs to 15 years later.
