Delaying treatments from what seems a fear of them for a year, allowed your cancer to progress to a more advanced stage, one requiring more complex and more difficult treatments. That was a poor decision. Quitting before your treatments are done would be a second one. You are lucky after a years delay to be here at all, and your willingness to so quickly quit when it gets a little tough may have implications in whether or not you are around a year from now. You haven't been around these boards long enough to have watched the deadly toll this disease has taken on people. It seems lost on you that this disease is killing someone in the US every hour of every day 24/7/365. It is unforgiving of delay and more unforgiving of half measures in eradicating it. Did you expect that you would walk through radiation treatments without any side effects? These treatments are brutal, and so far you have been lucky enough to miss the really difficult process that most go through. Now for a little discomfort you seem ready to quit. Perhaps you should read some of the postings here from the many, many people who have struggled in pain and discomfort, emotional turmoil, addiction to opiate painkillers, disfiguring surgeries, inability to eat, speak, and more just to get through their treatments and survive. It might give you a more balanced perspective on how lucky you are... if you let this get away from you right now and it is still there or returns, because of a recurrence of it, or an incomplete treatment, you will have a very different vision of decision making - you won't have any decisions to make. Hard talk... you bet. But you only are going to get one chance to do this.
