Important Reminders

Not everyone gets every side effect. Your experience will be unique based on your treatment plan, overall health, and individual factors.
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.
