I was walking 10+ miles every day when I was diagnosed with Stage 4 Lung Cancer, which means it was growing pretty much the entire time I was exercising. It’s not just Diet, exercise and sleep (and proper eating). Some of it is just plain luck.
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.
Good luck with the surgery!
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. :)
