Listen to your body
I was LUCKY, We caught it early (Non-small cell, lung), I had it removed, and no trace left.
BEST advice I can give - LISTEN to your body - and if you need to ARGUE with your doctor DO IT!!!!!! I had a mole on the opposite side that did not feel right - I went back 3 times saying "something is wrong" - They FINALLY scheduled me for a CT and found the cancer at stage 1.
I have to go back for a "follow up" with my "primary" - She and my secondary - are both "out" for the month. Fine I will see the nurse - THEN I am changing doctors
