In the JNCI article published September 6, 2019, entitled, “Screening mammography outcomes: risk of breast cancer and mortality by comorbidity score and age”, Dr. Demb and BCSC investigators aimed to identify subgroups of older women ages 75 and older who are unlikely to benefit from screening mammography.  Current clinical guidelines indicate that there is little evidence available to guide recommendations for whether or not women in this age group should screen, particularly women who have chronic illnesses.  To this end, the investigators compared the risk of being diagnosed with breast cancer and the risk of dying from breast cancer with the risk of dying from a non-breast cancer-related cause.  The study findings showed that while risk of being diagnosed with breast cancer begins to decrease slightly after age 75, the risk of dying from non-breast cancer causes increases dramatically with age, particularly among women who have other chronic illnesses.  This means that women ages 75 and older with chronic illnesses are unlikely to benefit from continuing to undergo screening mammograms, as their risk of dying from non-breast cancer causes vastly outweighs the risk of being diagnosed with or dying from breast cancer.  Moreover, these findings also underscore the need for more individualized screening strategies in women ages 75 and older and could inform the creation of tools that women could use to develop optimal screening strategies with their health care providers.
