While taking chemotherapy, you will have blood tests every 3 weeks to look at your blood counts. This is to ensure that your body has recovered from the chemotherapy enough to continue treatment. About 2 teaspoons of blood will be needed for each test. These samples will be used only for routine lab tests. You will be seen by a physician every 3 weeks. At these visits, you will have a physical exam and a chest x-ray. You may have a neurological exam if your doctor thinks it is necessary. This exam will look at whether you have any numbness, test your hearing and vision, and will include other standard evaluations. Your vital signs and weight will be monitored and you will be asked about certain side effects. If necessary, depending on your side effects, you may need to have more frequent visits to see your physician.
