Breast cancer treatment can affect estrogen levels leading to significant bone loss, osteoporosis, and risks for fracture. Although bone care guidelines are published, bone health interventions are often not routinely offered to at-risk individuals. This paper reports on the process of developing and implementing a nurse-led bilingual Breast and Bone Health Program (BBHP) in-person and online at a cancer centre in Montreal, Quebec (www.breastandbonehealth.ca, www.santeseinsetos.ca). The BBHP offers tailored bone health interventions (e.g., risk screening, information, rehabilitation, exercise prescriptions, nutritional counselling, and support for a health-promoting lifestyle). Over a two-year period, women treated for breast cancer (N = 430) took part in the program. Forty percent of surveyed participants (n = 97) initally reported being unaware that some breast cancer treatment could significantly affect bone health. Following the initial informational session with the BBHP nurse, self-reported bone health knowledge significantly increased, with 96% reporting sufficient information to manage their bone health. The BBHP offers both online and in-person risk assessment and bone health promotion activities and tools to both health care professionals and women with breast cancer. Herein, we review the background, BBHP development and implementation as well as preliminary program evaluation.
