Chemotherapy and radiotherapy should be given at the same time following a lumpectomy in order to minimise the risk of breast cancer relapsing, a new study says.
Researchers in the US tried different sequencing of chemotherapy and radiotherapy in 535 women who had already had surgery to remove the tumour.
Only 8% of those given chemotherapy and radiation therapy concurrently relapsed locally over a ten year period. Compared with 13% of those who received radiotherapy first and 22% of those who received chemotherapy first.
There was no significant difference in overall patient outcome.
