Older women with breast cancer can safely forego radiation therapy

New data suggest that it may not be necessary for women older than 65 with hormone receptor-positive breast cancer to undergo radiotherapy after breast-conserving surgery and hormone therapy, as it does not impact death rates or metastasis risk.

Some long COVID patients continue to display multi-organ damage one year after recovery

A new study utilizing multi-organ MRI scans recently identified organ impairment in 62% of COVID long haulers six months after their initial diagnosis; 29% of these individuals continued to display damage in at least one organ at the 12-month mark.
