Hello, I would recommend having Paisley seen by a veterinarian to check the lumps. A lump could be anything from a lipoma (accumulation of fat), a spreading skin infection, or a tumor, which could be either benign or malignant. The best way to find out what a given mass could be is histopathology with a surgical biopsy, but sometimes a needle aspirate can positively identify a tumor type or skin infection. A lipoma would not require any further treatment. A skin infection may be cured with a course of antibiotics. A more serious tumor may warrant x-rays, bloodwork, and ultrasound to be sure it hasn't metastasized extensively before surgery. I think it is absolutely worth investigating the cause of growths in guinea pigs. I hope this is helpful! If you get a diagnosis and have more questions, we will always be happy to answer them! :) Thanks for using Petco Pet Education Center, formerly Petcoach!
