Scientists estimate that reducing harmful chemical emissions could cut cancer risks from smoke exposure by over 50%.

About The Study: In this cohort study of older women with screen-detected estrogen receptor–positive or human epidermal growth factor receptor 2–negative breast cancer, prior screening mammography was associated with earlier stage at breast cancer diagnosis and lower breast cancer mortality. These findings support the potential for routine screening to improve breast cancer outcomes. As with all observational studies, this study is limited by the potential effects of other differences between the screening and nonscreening groups.

This is the first study to document the creation of a dedicated inpatient onconephrology service. The researchers highlight some of the challenges and future directions as well. 

Bar Harbor, Maine — A new study led by MDI Biological Laboratory identifies ML233 as a potent inhibitor of melanin production, offering promise for development of new treatments for pigment-related skin disorders and one melanoma subtype. The compound showed strong effects at low doses in zebrafish, mouse and and human cell models, highlighting potential for dermatological therapies.

Various tests – ranging from a tape measure to sophisticated imaging technology – show only low to moderate agreement in diagnosing breast cancer-related lymphedema (BRCL), reports a study in Rehabilitation Oncology, official journal of APTA Oncology, an academy of the American Physical Therapy Association (APTA).
