Have some symptoms of g.e.r, how can i treat? it will it go away on its own? should i worry? and can it cause things like lets say a tumor? im nerves.

I assume you have Ac: If it is acid reflux you are talking about, it is easily treatable with antacids. No risk of cancer if you take antacids regularly. You can take medicines like Pepcid (famotidine) or zantac(cheapest drugs to use). More potent drugs are Prilosec or omeprazole...They are very potent and highly effective but cost a bit more.You should try and find out which one works best for you.
