HI PCBBCOACH,
Welcome to Healing Well! You're definitely in the right place, as what you're describing are symptoms of GERD/reflux and LPR. Many with GERD/LPR worry that they'll get or already have cancer, but it's rare, and just because you're having those symptoms does NOT mean you've got cancer, so RELAX. Take a breath. Being anxious and stressed out can make your reflux worse, so try to calm down.
Here is a link to a Mayo Clinic page that provides lots of information about GERD and its symptoms and treatments. Check it out:
http://www.mayoclinic.com/health/gerd/DS00967/DSECTION=symptoms
Here's a link to Cleveland Clinic's LPR information:

Don't drive yourself crazy looking for cancer symptoms and assuming you have it. It is EXTREMELY unlikely. Get yourself to you primary care doc and see if he/she will refer you to a GI doc. It's not a huge rush, so don't panic if you can't get in to see someone right away. You'll be fine.
I'm sure others will be by to share their own experiences and support.
Hang in there!
Best wishes,
Denise
