Which of the following is NOT a side effect of radiotherapy?

In the context of radiotherapy, side effects can arise due to the treatment's impact on surrounding healthy tissue. Anorexia, sloughing of skin, and bone marrow depression are all recognized potential side effects of radiotherapy.

Anorexia is common as patients may experience nausea or changes in taste and smell due to the treatment. Sloughing of skin can occur in irradiated areas because of skin cell damage from radiation exposure, leading to skin breakdown. Bone marrow depression can result from the radiotherapy affecting the bone marrow, which is responsible for blood cell production, leading to complications like anemia, increased risk of infection, or bleeding.

In contrast, increased appetite is not typically associated with radiotherapy. In fact, many patients experience a decreased appetite due to various factors like nausea, fatigue, and psychological impacts of cancer treatment. Therefore, identifying increased appetite as not being a side effect aligns with the common effects experienced by patients undergoing radiotherapy.
