I had the same thing, however, mine wasn't quite a pea sized lump...it was like an uncooked noodle, about a quarter of an inch or so. It was located on the right side of my tongue, and was about an inch or so from the tip of my tongue. I saw three people... my primary doctor who told me he was 85% sure it wasn't cancer, but then told me he wasn't sure what it was (who does that?), I saw my dentist who told me it was an infected or swollen gland (but also told me to see an ENT), and then an ENT who told me that it was an inflamed saliva gland, and she did the whole cancer screening on me.. through the nose, down the throat, everything. I used chewing tobacco for over 15 years, and the results came back as not cancerous. I was more worried then anyone will ever know. I guess what I want to tell you all with this problem is... Don't worry until you need to. There are many things that this could be, but go get it checked and move on. Also, early detection is a life saver, so keep tabs on yourself. The earlier the better. If ever in doubt, go get it checked out. My friends make fun of me because I tend to worry more then I should, but there is no price for my piece of mind. I hope this helps someone. And remember the power of the mind. If you believe you can... you can. Take care all!
