![]() Meaning that we don't always get a specific answer. After which, we can carry out a fine needle aspirate or an FNA or it might be that we want to take a further, larger biopsy.Īnother consideration is that a fine needle aspirate does not always give an absolute, definitive diagnosis. Now, in some cases, for example, if a mass was really close to an eye or a dog or cat was really sensitive because the lump is really sore, then it might be that it is not the best option and we need to sedate them. A dog and a cat won't really notice that the test is being carried out. We do not need to worry about local anesthetic or anything like that. In the vast cases, we do not need to administer any sedation. In some cases the mass will be sent to a pathologist for their opinion of mass type. After the sample is spread onto a slide and stained, your vet can look at the cell type under the microscope. We then suck up a few cells using a syringe or by moving the needle backwards and forwards into the mass. What happens here is we take a small, thin needle and we pop that into the mass. ![]() The quickest way that we can check mass type is to perform something called a fine needle aspirate or an FNA. Well, ideally all masses or lumps that are larger than a pea or that have been present for longer than a month should be checked out by your vet. So how do we know if a tumor is a benign lump and we do not need to worry about it, or if it is a malignant lump That really needs to be either removed or treated aggressively some other way? Your vet will have to go quite a long way outside of where the obvious tumor appears to be to try and make sure that we completely remove that mass. These tumors ideally need to be removed and some of them will need to be removed with a really wide margin. Secondary tumors can form elsewhere in the body. Typically, that's the lungs, but it can also be the liver and kidneys or anywhere else really. The other big issue with malignant tumors, cancers, is that they spread to other parts of the body. They can cause real problems with where they are or because they often ulcerate. Malignant tumors are nastier types of mass. Another reason to make sure any mass is checked, even if it appears pretty innocuous. That’s not the case for all benign tumors however. ![]() These can often be safely left if they are not causing a problem, ulcerating or growing rapidly. Also, lipomas would fit into this category, which are a very common lump that we get, generally under the skin of larger breed and especially overweight dogs. ![]() We have benign masses like skin tags or sebaceous cysts. Benign means that although they are growing in that local area, they will not spread to other parts of the body and cause problems elsewhere. ![]() We have things like skin tags or sebaceous cysts, which are benign lumps. Different types of masses, they do need to be approached differently. Whether this mass needs removing or not is the next question. I certainly would not encourage you to go chopping bits off your dog willy-nilly! Different Types of Mass How do I remove it? - Stuartįirst things first, only a qualified veterinarian can perform an act of surgery on an animal. It’s clean and does not appear to be infected. Tucker has a wart-like cyst on the outer flap of his ear - about 3 mm across and round. ![]()
