My neutered dog has a soft, growing scrotal mass. Is it a fatty tumor?

I'm wondering if your dog was neutered recently - it almost looks like there could be a scrotal incision and discharge in the center of the photo. Either way, the raised area looks like it could be a growth, tumor or abscess/infection and if he was not neutered recently the discharge is concerning. I would definitely recommend having your vet take a look.

From the pictures you have sent the "bump" appears to be a skin growth. There are several types off masses that can grow in the skin of dogs such as cysts, lipomas and some types of cancers. Some are benign and some are malignant, so careful observation is important, as well as having a vet examine it if you are concerned. Since you only just noticed the lump, and Doom is neutered, I would continue to monitor it for growth, ulceration, changes in texture or color. Measure the mass with a ruler so you can compare its growth in a couple weeks time. Rapidly growing masses are more concerning. If the mass has grown or changed in that time I would advise taking Doom to have the mass examined and analyzed. I hope that this answer was helpful and more importantly that Doom feels better soon. Warmest regards to you both.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

This may be blood blister, a tumor, or a small benign growth. The only way to know what it is and if it is a cancer is to have your vet remove it or biopsy it. At his age, cancer such as a mast cell tumor or hemangiosarcomas are possibilities and the smaller they are when removed, the better the chance it can be completely removed.

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Dodger 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.

This could be a seroma from an injury, a cyst, abscess or a tumor. Cysts and abscesses need to be drained by a vet. If your vet suspects a tumor, he will do a fine needle aspirate to determine whether it is a harmless lipoma, which does not need to be removed unless it is ulcerating or bothers the dog due to its location or size, or another tumor that needs to be removed. Please make an appointment with your veterinarian for an exam of the mass.

It is possible that a hernia might have formed where the testicle was previously removed. Or this could be a mass unrelated to the testicle or the castration. Either way, you need to have Steven examined by your veterinarian to determine exactly what is going on here. Your veterinarian can make treatment recommendations once she figures out what is causing the lump.
