It's technically on her hip, an inch or two from the base of her tail. I just took this pic with my phone a couple minutes ago, it's the best I could get:
It's been there for a few months. Recently, Isabeau has started licking the area a lot, acting like it bothers her. After reading about other member's experiences with Mast Cell Tumors, I realized I should get the vet to take a look at it.
The vet said it was kind of an odd looking growth. It's pea-sized, round, flat, and hard. She tried to aspirate it to get a sample for cytology, but couldn't really get anything. All she did was manage to make it bleed and turn red (and make Isabeau super-nervous, so she released her anal glands
She gave me anti-inflammatory/pain pills, and told me to up Isabeau's benedryl for the next few days. She wants to see if it will shrink. If it doesn't shrink in a week, she said she would definitely have it removed and sent to the lab. She said she wasn't sure what it is, it could be anything. She would not rule out MCT, but said it also didn't look like most MCT's she's seen. She said Isabeau needed a dental anyway, so she recommended we just go ahead and "kill two birds with one stone", which is fine by me.
When I checked out at the front desk, they gave me a print out of the estimate for everything. I noticed they just called it a "growth removal- small" and it was listed as only $30 extra. Call me crazy, but it doesn't sound like she's planning to treat it like it IS a MCT, since I would imagine taking out 3cm margins all the way around the growth would be a bit more involved and cost a lot more than $30. So do you guys think I should ask her to treat it as if it WERE a MCT??? Or should I trust her judgement and let her do what she thinks is best?
