Tumors are very common in rats, I've had 4 pet rats and all of them after about 2 years started getting large abscesses on their bodies. 3 of them I had removed and they only lasted about 2-4 months. Thankfully my family is really close to one of the vets near me and they removed the tumors for about 10-20$ per rat. I would in no right mind spend 360$ on a rat that only lives about 2-4 years.
