UTHealth research: Older breast cancer patients less likely to benefit from chemo

A study published in the Journal of American Geriatrics Society found that chemotherapy's effectiveness in prolonging life for older adults with most types of cancer is reduced for women over 80 with breast cancer. However, combining chemotherapy with another treatment may improve mortality risk reduction for this age group.
