Cancer in beardies?

[wikidinc528]

Hi again, I apologize if I upset anyone by reposting this. My bd has a lump on the right side of his bearded. He has always looked a little crooked, but it was very pronounced this morning after he ate some supers. I have the picture here via snapfish:

I am very worried that this is a sign of a tumor or a disease. I have only had him for four days.
Some quick info:
Temps: Basking range from 95 to 115 (5 different areas) cool side 80s
Light: Powersun UV 100 W MVB on a 5am-7pm cycle
Thermometer: Proexotics Temp Gun
Humidity is low
Substrate: Slate tile
Food: Either superworm or small turkish roaches until my colony takes off, offered a salad every day. Lately have used collards garnished with maybe half a diced strawberry. Today it was collards and acorn squash shredded. I spritz salad with water. He doesn't seem to eat it though.
Poo: Has been poo-ing fine and I clean it as soon as I see it
Water: Has dish and I spray him in the morning, doesn't seem to really drink though. I bathed him Sunday when I got him home.

I rescued him from people who were *****s. He was not handled much so I have been trying to not touch him but spend time with him so he gets to know me.

I know that beardies can sometimes "stash" food in their throats or it can get stuck, but I just wanted to get some opinions as he is my first bd and I want to treat him better than he has previously been treated.

Thanks. If the link doesn't work, then I will update with a picture once I am able to access my home pc (I'm at work right now.)
