The results of Susan McDonald’s bone mineral density screening were troubling. Bone density had decreased 3 percent in her spine and 3.6 percent in her hips since a scan done two years earlier. Given her history of breast cancer and the potential that related treatments might further sap her bones’ strength, McDonald needed a plan to improve her bone health.
Her oncologist, Catherine Van Poznak, M.D., outlined some options to address the thinning in her bones, which in the case of her hips had progressed to a precursor of osteoporosis called osteopenia. McDonald, a 72-year-old Ann Arbor resident, decided to make a concerted effort to increase her walks from 20 minutes to 30 minutes per day, covering about a mile-and-a-half to a mile-and-three-quarters during each outing.
Two years later, McDonald’s bone mineral density was much improved.
“I’m a small, fine-boned woman who’s likely to get in trouble with bone problems,” McDonald said. “But they were talking about osteopenia in my hips two years ago; they’re not saying that anymore.”
Bone health may be of particular concern for people with a history of cancer, said Van Poznak, a University of Michigan Comprehensive Cancer Center oncologist who specializes in breast cancer’s relationship to bone. People with breast or prostate cancer who undergo treatments that block specific hormones may be at higher risk of thinning bones. Also, certain chemotherapy drugs used to treat these or other cancers may induce ovarian failure in younger women, causing bones to thin as a result of early menopause and estrogen deprivation. In addition, steroids may also accelerate bone loss in both men and women.
Although cancer treatment may increase the likelihood of developing osteoporosis — which may lead to painful bone fractures — many options are available to prevent it, Van Poznak said. The key is to talk to your doctor early to develop a plan of action. Here are six steps you can take to improve your bone health. Continue reading
