34 year old triathlete here: colon cancer spread from my colon to my lung. That said, I do think continuing to do some amount of exercise during chemo definitely helped me recover, if not just stay sane mentally.

I'm about to have surgery to remove part of the lung and tumor and my surgeon/oncology team is making me wear a fitbit for three months to study my recovery.

What did you do for exercise? Do you mind me asking what your chemo was? Was it mutation-specific?

I was on Folfirinnox + Avastin. 2 week cycle with three actual days of chemo, five shitty days and then a recovery week. Exercise was really dictated by my port surgically put into my right peck. After about four weeks I could deadlift, squat, all the compound lifts + run,bike,swim if I had the energy.

The surgery was supposed to be VATs, but the tumor was so large it turned into a general thoracotomy. It's fucking brutal. Easily the hardest thing i've had to do in life so far. But I'll get through it because there's no other choice. Forward. :)

Sorry that sucks and is doubly frustrating when you are doing everything right. Sort of the inverse of Richard Overton who would chain smoke cigars and drink Irish coffee well into his 100s.

I'm sorry to hear that. Theoretically, it could have progressed faster if you hadn't exercised?
