When do radiation side effects like fatigue typically start after treatment?

Both radiation aftereffects and hormone therapy medications can contribute to fatigue, making it challenging to pinpoint the exact cause without professional guidance. Discussing both possibilities with your doctor next week will help create a clearer picture of what might be contributing to your low energy levels and explore potential management strategies.
