Though many women are aware that bone health is an important health topic, many breast cancer patients are unaware of the connection between bone health and cancer. Board-certified oncologist Wayne Keiser, MD, offers important information for cancer patients.

How can breast cancer affect women’s bones?

Breast cancer and bone health are closely connected, and the issue is twofold. There is a natural balance between bone loss and regrowth, which normally maintains healthy bones.

First, many women receive hormonal therapy as a treatment for breast cancer. A side effect of this treatment is potential bone loss, which can weaken bones and place women at risk of fracture. Compounding the problem, medications given with chemotherapy can prevent bone regrowth. Therefore either treatment, or both, can upset the natural balance, resulting in increased bone loss and risk of fracture.

Second, as breast cancer advances, it can spread to a woman’s bones. This can also result in very serious problems, such as broken bones, spinal cord injury, and the need for procedures like surgery or radiation.

How common is bone loss from treatment? What about cancer spreading to the bones?

It is estimated that hormonal therapy can result in bone loss occurring as early as one year after the beginning of treatment and that fractures can occur in nearly 5 percent of patients receiving hormonal therapy.

Up to 75 percent of women with advanced breast cancer will experience the spread of cancer to their bones.

When we talk about the top health issues women face, breast cancer and bone health typically spring to most people’s minds. Many women, however, don’t realize that these two issues can be connected and that breast cancer can have a potentially serious impact on their bones.

This is an alarming statistic that points to the need for increased awareness and attention around bone health in patients living with breast cancer.
