I would absolutely have it taken out, even if it turns out not to be cancerous, doing it while he is already knocked out will save him an extra round of anesthesia if it turns out to be cancerous, and there's no reason not to get rid of it!

I, myself, am on the "good riddance to bad parts" plan, and have never regretted it!
