This 8-year-old Miniature Schnauzer had a circular skin lump, 1.5cm across, located at the tail end. I advised removal as it could be a skin tumour growing bigger as this dog is old.
"It could be due to biting from anal sac infection," Dr Daniel expressed his view. "8 years is not old for a dog."
"Dogs over 7 years old are considered old," I said. "This skin lump may be inflammatory but nobody can tell. It may develop into a cancerous skin tumour later if not removed early. If you wish, do a biopsy to check."
I did not propose biopsy in this case as the owner was willing to get it cut off. Biopsy will take some time and cost money. Even if the tumour is benign from a biopsy, there is no guarantee that it will become malignant.
Dr Daniel operated and the lump was sent for histology on Monday Feb 9, 2015.
