My senior dog has a growing, scabbing chest lump. What are my options?

Pet's info: Dog | Border Collie | Female | unspayed | 12 years and 7 months old | 60 lbs

My dog is 12 and for the past year a lump has grown pretty big,it’s on her chest at her front paws and now it’s scabbing in 2 places, she hasn’t been off her food and doesn’t seem to be in much pain however the past few weeks she has started doing the toilet in the house during the night, I’ve looked up a price for removing lumps and it’s looking very expensive also I’m not sure if she will survive a big operation. Please can you advise me of my options. Thanks debbie

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. The accidents in the house are unlikely to be related to the mass. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!
