What is a common side effect of hormone therapies for breast cancer?

Hot flashes are a well-known side effect of hormone therapies for breast cancer, particularly in women undergoing treatment that alters estrogen levels, such as tamoxifen or aromatase inhibitors. This side effect is primarily due to the changes in hormone levels that can lead to vasomotor symptoms, which include sudden feelings of warmth, flushing, and sweating. These experiences are often associated with the menopausal transition, as hormone therapies often mimic or induce menopause-like conditions in the body.

Unlike weight gain, which can occur but is not universally experienced and is influenced by a variety of factors, hot flashes are more consistently reported among patients receiving hormone therapy. Increased hair growth and enhanced energy levels are not common side effects associated with these hormonal treatments; instead, patients often report experiencing fatigue as a result of treatments or the disease itself.

Recognizing hot flashes as a significant side effect helps both patients and healthcare providers manage this symptom effectively, preserving quality of life during cancer treatment.
