Piglet, 3.5yo, pugxlab, i noticed last week that she had a pink lump on her belly, it is hard and not attatched to her ribs or anything, i haven’t been home a lot since then but yesterday i notice it had gotten a scab on it and has gone a weird colour. Do you think it’s benign or should i go get tests? the shape or size hasn’t increased, i think it’s decreased in size very slightly

Hopefully it's nothing but any red, raised mass is concerning for a skin cancer called Mast Cell Tumor. Many other lesions though can look this way but I think it's always best to play it safe and have it tested. Aspirations of a mass are generally quick and easy and most pets tolerate them well. I hope this helps and please feel free to post any additional questions.

That pink mass could be something completely benign or it could be a cancerous tumor called a Mast Cell Tumor. Just like with humans, you often can’t tell by looking. The problem with Mast Cell Tumors is that they can look like anything. I recommend to have Bella visit her veterinarian and have the mass aspirated. This will collect a small sample of cells and this will tell you what it is and if further action is needed. Even benign tumors can become inflamed, especially if Bella is chewing in it. It’s always better to be safe than sorry. Hopefully it’s nothing serious! I hope this is helpful and please feel free to post any additional questions.
