I noticed a trembling in my thumb a few hours ago. it doesn't hurt i noticed it when i picked up my tooth brush. does this sound like brain cancer?

No: This sounds like fasciculations. Everybody gets these in some muscle group of other from time to time. They last briefly then vanish as mysteriously as they arrive. I suspect that a portion of a nerve is temporarily damaged, leaving a bare receptor that then becomes hypersensitive to circulating acetylcholine. What we do know is that what you're describing isn't worrisome.

Tremors: Probably not cancer, but prudent to determine cause. Can be as simple as an electrolyte imbalance. Have you seen your GP for an examination? Referral to a Neurologist may be in order.
