My dad is undergoing chemotherapy for small cell carcinoma of the lung.  He is on procrit for low RBC and is diabetic, but controlled.  He is 74, 6 ft tall and 196 lbs (lost 30 lbs since Feb 2011).  He is scheduled for a chemical stress test tomorrow and I am wondering if he should wait and reschedule.  Thank you.
Hi, Thanks for writing in. Chemical stress test might be done if his general health condition is satisfactory. His doctors will confirm his tolerance level and check his vital parameters before doing the chemical stress test. This will make sure that the test will not compromise his health and the fact that he is under chemotherapy for small cell cancer lung. Please follow instructions before the test and in case of any discomfort or weakness he can inform the doctors performing the test and then if he is not keeping fit then he can reschedule the test. Many people get the test done without any risks to their health. There will be emergency medicines at the time of doing the test in case he feels uncomfortable at any time during the test process, and he should promptly inform. Please do not worry.
