Can neutering help my unneutered dog's hormone-related anal tumor?

Yes, it is true that dogs who haven't been neutered are prone to developing anal tumors. Given I can't see him in person, I can't say what the best course of action is for him, but following your vet's recommendation would be best for him in my opinion :-)

A hepatitis adenoma is also known as a perianal adenoma. These are typically benign meaning they are not malignant and do not spread to other sites from the primary site. They typically occur on the prepuce, anal area or limbs. They can become necrotic and infected if not removed. The best course of treatment is surgical removal and castration as there is some belief that these are hormonally induced. Your biopsy report does not state whether the surgical margins were clean of abnormal cells. If they were clean, this tumor is not likely to recur in the same site. Your dog can possibly grow other ones but neutering him will help to reduce that likelihood.

Poor Alf! Studies have shown that neutering does not provide any protective effects against prostate cancer in dogs - in fact, neutered males have a slightly higher incidence of this disease than intact males. So I'm not quite sure about the reasoning for having him castrated, unless what your veterinarian meant was that Alf has prostatic cysts or benign prostatic enlargement - both of these things would be expected to improve with neutering. It would help to know exactly what diagnostics have been done and what the results were in order to give more specific advice - feel free to request a consultation with one of us if you want to upload copies of his lab reports and medical records for us to look at. Otherwise, if you're unsure about your current vet's recommendations, I would suggest going to another local vet for a second opinion, or requesting referral to a specialist for further evaluation.

Yes, I would recommend at the least having Dino neutered. Perianal hernias are almost always due to increased testosterone levels which weakens the muscle of the pelvic floor. Neutering would help prevent further damage to these muscles but would not reverse the problem. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If the tumor shrunk significantly, hasn't grown and isn't impeding or doesn't have the potential to block his anus then I would just monitor it. Remember that masses are easier to remove when they are small. If the mass starts to grow or bleed (these tumors have this potential) then I would remove it right away before it gets too big. I wish you and Willie the best!

I see that Baobei isn't neutered, and a type of tumor called a perianal adenoma are common in intact males. There is a malignant version of this tumor called a perianal adenocarcinoma, and while it is is less common that the perianal adenoma, it carries a fair to guarded prognosis. I would have him seen by a vet to diagnose if this growth is benign or malignant, and the vet can discuss treatment options with you.

I don't blame you for being concerned! You're right that congestive heart failure does increase the risk associated with anesthetic procedures, so we want to be very cautious about going forward with surgery in dogs who have this problem. I would recommend sitting down with your veterinarian to discuss the pros and cons of doing the neuter surgery in Wesley's case. In particular, you may want to ask about his life expectancy with congestive heart failure, and whether it's likely that the testicular tumor will progress enough to cause any serious problems before that. If the tumor appears to be slow-growing and is not currently bothering him, it may be reasonable to leave it alone rather than take the risk of surgery.
