Your doctor and nurse will use several ways to see how well your treatments are working. You may have physical exams and tests often. Always feel free to ask your doctor about the test results and what they show about your progress. Tests and exams can tell a lot about how chemotherapy is working; however, side effects tell very little. Sometimes people think that if they have no side effects, the drugs are not working, or, if they do have side effects, the drugs are working well. But side effects vary so much from person to person, and from drug to drug, that side effects are not a sign of whether the treatment is working or not.
