anal sac tumor

My pet was diagnosed with anal tumor:

browsing the internet, I found there two types anal sac and perennial gland tumor.

Anal sac tumor, it seems like more aggressive type than perennial gland
but both depend on whether the tumor is benign of malignant.

I attached the picture to the forum, and hope to hear from people, maybe they saw similar tumors before and what course of action they did with it.

thank you

What did your vet recommend?

No one can tell just by looking at it what kind of tumor it is. You need some kind of sample, either a needle aspirate or a biopsy, you should talk to your vet about your options.
