Please listen to christine. from what i read on this site she is a very informed person . the most important thing you can do for yourself is quit smoking. I know its hard as i quit smoking 3 packs of kools back in 1985 cold turkey. i could pick up a cigarette and smoke it right now so you never loose the urge. i take it one day at a time. today i chose not to smoke. good luck and god bless that its not cancer we'er rooting for you. pat
