Ok...
Many moon's ago, I found myself in need of a new cpid for Air Warrior. So, I grabbed a dictionary, closed my eye's, opened it and stuck my finger on the page. Turns out, my finger landed on "Tumor". At first I thought "oh hell, thats terrible", but then I reflected on the fact I'd had 2 real "Tumors" surgically removed, I figured it fit.
