My guinea pig has a growing lump on its side. What is it? Home care?

Thanks for reaching out about your guinea pig. Common ear masses are abscesses (infections) and benign wart-like growths. Due to the nature of guinea pig pus and its thickness, both these conditions probably will require some surgical intervention. Seeking a veterinarian and having the mass lances with a surgical blade will help diagnose the problem but also possible remove it. Good luck.

Thanks for reaching out about Sprou and including pictures. By the history and pictures, the most likely answer is a dermal (sebaceous) cyst. This condition is very common in middle aged guinea pigs. Keeping it clean as you did, is a good start. Clipping the hair around the edges to prevent further contamination is important. Ideally a veterinarian should be seen to have the cyst surgically removed, else it is likely to come back, over and over. Secondary infections of the open wound are also possible. Good luck.

This could be potentially rubbing against cornea and in the long term cause both chronic irritation/inflammation (the cornea can get darker than normal) and possibly corneal ulceration. This lump/growth should be ideally examined by your veterinarian to have a definitive diagnosis. Your vet will examine it and possibly perform with an FNA (fine needle aspiration) or a biopsy. Differentials would include skin cyst, infections or benign or malignant type of tumors.

Hello! Masses near the breast area of a guinea pig could be a few different things. My first thought is a mammary tumor, which is common in rodent species, especially as they get older. Mammary tumors in rodents are usually benign, but rarely they are malignant and could spread to other parts of the body, so most vets generally recommend surgical removal of these masses if the guinea pig is healthy enough for surgery. The mass could also be a fluid-filled cyst or an abscess. All of these diagnoses will require the help of a veterinarian to confirm. At the vet, they will give Lola a complete physical exam, and they will most likely collect a small sample of cells from the mass to look at under the microscope with a small needle. This is called a fine needle aspirate, or FNA. The type of tissue or liquid that comes out, as well as what those cells look like under the microscope, will determine the recommended course of action. If it's a tumor, they may suggest removal. If it's a cyst, they may just drain it and ask you to watch for recurrence. If it is an abscess, it will also likely be drained, and Lola will probably be put on antibiotics. I strongly suggest that you make an appointment with Lola's regular vet, or, if you don't yet have one, with an exotics specialist. Here is one that is nearby: Northwest Exotic Veterinary Clinic 572 S Bartlett Rd, Streamwood, IL 60107 (630) 540-2490 Good luck, and I hope Lola recovers well!

Have him examined by your veterinarian or a vet experienced in treating pocket pets. A fine needle aspirate can be done to collect a sample for pathology. This may lead to a diagnosis. In the meantime, make sure he is eating, drinking and eliminating normally.

My best guess is that this could be ringworm however it is impossible to tell just by looking at a photo. I suggest you get this spray and apply it 2-3 times daily on the affected area. ( https://www.petco.com/shop/en/petcostore/product/vetericyn-plus-antimicrobial-wound-and-skin-hydrogel-for-pets ) If after a week to 10 days it still is not resolving then you need to take her to a vet for an exam. Wash your hands thoroughly after touching her as ringworm, if it is that, is contagious to people.

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!
