I am diagnosed with Stage 3 Squamous cell cancer. I am 65 suffering from Type 2 Diabetes, Congestive Heart Failure and Hypertension. Currently all are under control and I am doing well. I had a stroke in Dec, 2012 but recovered from that as well. My first scan showed a tumor size of 4.2 * 4.3 * 3.3 cm about a month ago. In my recent scan the tumor size is reduced to 3.8 * 3.6 * 3.2 cm without doing anything. Should I wait a little longer before starting radio therapy hoping that my tumor will shrink more? Currently I am not facing any major problems due to the tumor. I know you all have experience coping with various problems related to cancer and hoping that I can find some answers. Thanks in advance!
