For women diagnosed with early-stage breast cancer, the long-term risk of developing a second primary cancer is low, around 2–3 per cent higher than that of women in the general population. This is one of the conclusions of a study published by The BMJ, which analysed data from nearly half a million women diagnosed in England between 1993 and 2016 with early-stage invasive breast cancer who underwent surgery. During a follow-up period of up to 20 years, around 65,000 women developed a second primary cancer, but the absolute excess risk compared to the risks in the general population was small.
A standard chemotherapy drug injures surrounding noncancerous cells, which can awaken dormant cancer cells and promote cancer growth, according to a study published today in the journal PLOS Biology.
