What is a common side effect of radiation therapy after lumpectomy?

• A. Nausea and vomiting
• B. Fatigue
• C. Weight gain
• D. Hair loss on scalp

Answer: (B)

Fatigue is a well-documented and common side effect of radiation therapy following a lumpectomy. Radiation treatment works by targeting and destroying cancer cells, but this process can also affect healthy tissues and overall body energy levels. As the body uses energy to repair and heal from the radiation exposure, patients often experience an increase in tiredness and fatigue.

While nausea and vomiting can occur with certain cancer treatments, they are not the hallmark side effects of radiation therapy after lumpectomy. Weight gain is generally not a direct side effect of radiation and may result from other factors such as hormonal changes or lifestyle modifications rather than the treatment itself. Additionally, hair loss typically occurs only in the area that has been irradiated; since lumpectomy patients usually receive radiation to the breast area, scalp hair loss is not a common side effect for these patients.

Thus, fatigue stands out as a significant and frequent side effect that individuals undergoing radiation therapy often report.
