I had Pre surgery chemo and Radiation in 2009. I was 42 at that time. That is still considered very young for this type of Cancer.
I elected to take my chemo thru a port and go home each day with it instead of sitting at the clinic. The chemo did make everything taste terrible and my family had to force me to eat a few bites of something each day. There were only a few foods I could tolerate eating during that period and it also took months and months before food begun to taste better again. I lost about 20 lbs from 6 weeks of Chemo.
For me the worst was the Radiation. What it does is like burns your tissue and makes it raw as the days go further into treatment. The first week or so was not so bad, but the further you get into it the worse it got. The last two weeks my family had to drag me there and I would be very upset insisting I couldnt take anymore. I am not going to get into the gorey details of what you go thru or feel but I can say that what I went thru did succeed and my Tumor shrunk quite a bit and it is now 2 yrs later and I'm still here so that in itself was worth it. Because of where the Tumor was located I now sport a colostomy for life, but that too was dealt with and I made the adjustments in my life to support all the changes that have occured.
In my opinion I'd rather go thru all that hell one time then just get the surgery and with no treatment and they didnt get it all and have to be operated on it again. The surgery was not pleasant either, the after...the recovery.
Just do what you have to do, be strong and believe you can beat this.
