What is a common side effect of radiation therapy in cancer patients?

Nausea is a common side effect of radiation therapy in cancer patients. This occurs because radiation can affect not only the targeted cancer cells but also nearby healthy tissues, particularly those in the digestive system. The treatment can lead to inflammation and irritation of the stomach, which commonly results in feelings of queasiness and vomiting.

In contrast, options such as increased appetite, hair growth, and improved energy are not typical side effects associated with radiation therapy. Increased appetite is often the result of underlying health factors or treatment responses, and many patients experience a decrease in appetite instead. Hair growth may be influenced by factors like genetics and health, but radiation can lead to temporary or permanent hair loss in the treated areas. Improved energy levels are generally not linked to radiation therapy, as patients often report fatigue as a significant side effect due to the strain of treatment on their bodies. Understanding these effects helps caregivers manage patient symptoms and expectations during cancer treatment.
