- Most side effects are temporary and resolve after treatment ends. Some may take weeks or months to fully improve.
- Prevention is often easier than treatment. Follow your care team's recommendations for preventive medications and strategies.
- Report side effects early. Don't wait for them to become severe. Early intervention is usually more effective.
- Never stop treatment without consulting your oncologist, even if side effects are difficult. Dose adjustments or supportive care can often help.
