My bunny has a weird bump on his back, but acts normal. What is it?

The best thing is to gently feel the lump and figure out how big it is ( for example, as big as a cherry pit, or measure it if you can. Write this down and then measure it again a week later. If it has grown, you should take your rabbit to a veterinarian as it could be a tumor or a cyst or an abscess. If it does not grow and does not ooze nor the skin starts to turn red, then I would not worry about it, and only show it to your vet the next time you take Albie in for an exam or vaccinations.

Thanks for reaching out about Charlie and including a photo. My the picture, it appears to be a scab with no discharge. Monitor the site for increase in size, seeming itchy or any discharge. If these are noted, a veterinary visit is recommended. Good luck.

Lumps and bump can certainly be scary, especially since we usually don't have any idea what they are. As long as it is not effective Poppy's ability to urinate and defecate, and as long as she is eating / drinking / having a good energy level, there is not absolute rush to have her seen. However, I would definitely get her to the vet to have that area examined as soon as it is financially feasible to do so. It is in an area of the body where if the size increases, the mass could certain become problematic. It is best to deal with it sooner than later. If the area starts to grown in size by even 10%, I would not wait until the insurance kicks in and just get her somewhere to be examined. While I realize this isn't ideal, rabbits are very sensitive to changes in their health and have the ability to crash quickly if things are not hastily dealt with. If you have any others concerns, don't hesitate to contact me. Hope this helps!

This kind of lump/growth needs to be ideally assessed by your veterinarian to have a definitive and specific answer. Usually there are two ways your vet can do that a part from examining it directly during physical examination. A biopsy can be taken under local or general anesthetic, otherwise a smaller sample through a fine needle can be aspirated (this technique is called FNA= fine needle aspiration). Differentials include skin cysts, infections, benign or more sinister type of tumors. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Thanks for reaching out about your rabbit and including a photo. This appears to be a trichofolliculoma (ingrown hair cyst). A veterinary visit is needed to remove (surgically) but need to wait until much older. Monitor for now, do not apply anything topically. Good luck.

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take him to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

If the bump is appearing where the abscess was, then I'd be concerned that it is reoccurring (a common problem with abscesses in rabbits). It's best to have your vet check him as soon as possible, because these are much easier to remove, the smaller they are. I hope that helps and Bun gets better soon.
