The investigators also want to learn more about how to manage side effects the patient may develop during chemotherapy. Cancer patients may develop side effects during treatment, such as nausea, pain, fatigue, diarrhea, constipation, or shortness of breath. These symptoms may be due to the cancer itself, or due to treatments. Doctors and nurses often ask patients about their symptoms, because an important part of cancer treatment is to make patients feel as well as possible. If patients do not feel well, the investigators may need to change the way they are treating the patients or prescribe therapies that will decrease their symptoms.
