A new Canadian study suggests that older women with early, low-risk Breast Cancer may not need radiation treatment, potentially sparing them from harmful side effects. The study tracked 500 women with luminal A breast cancer and found that those who met certain criteria could be effectively treated with surgery to remove the lump and hormone therapy alone. The study's lead author, Tim Whelan, says that identifying women who don't require radiation treatment will allow them to avoid the inconvenience and side effects of the treatment. However, further research is needed to determine the long-term effects and benefits of radiation in low-risk patients.
