question: Dear Drs,My father has been diagnosed with lung and adrenal gland cancer, in which the spreading point was from his lungs. We asked for more than one medical opinion regarding his treatment and basically we have two options; the first is to conduct several extensive chemotherapy sessions and then switch to radiotherapy or surgery. The second was that his condition was very rare that it can be treated by surgery first and then less sessions of chemotherapy can be conducted. I know that the immunity for a person gets very low after having chemotherapy and I am really concerned of him having chemotherapy first and surgery afterwards, so I want to ask which of the two options is a better one? And whether there are any other options for treatment? My father is 63 years old, a smoker, has type II diabetes, and had successful colon cancer surgery in 1983.I would really appreciate your medical opinion in this case and hope to get your answer very soon.Thank you,Tina
