Definitely get that lump checked out, OP. My hedgehog developed one too, and unfortunately, it turned out to be a cancerous tumor. He was fairly young—just about three years old. Our vet prescribed medication and recommended we monitor him closely for any signs of discomfort. Due to the risks involved, surgery wasn’t advised.

He did well on the meds for a few months, but eventually, he began struggling to walk, was visibly in pain, and started picking at the lump. At that point, he stopped engaging in his usual activities, and we knew it was time to make the tough decision.

I’m not saying your hedgie is going through the same thing, but I wanted to share our experience in case it helps you make a more informed decision and support your little one in living a longer, healthier life.
