672 – Lumps and Bumps: From Benign to Bad

Lumps and Bumps: From Benign to Bad

Dr. Marty Greer joins host Laura Reeves for a deep dive on the various lumps and bumps we see on our dogs, from benign to bad, from histiocytomas to osteosarcoma.

“Histiocytomas are really, really common. And they are really scary looking because there are these pink bumps that show up on young dogs and they come seemingly out of nowhere. It’s usually on the head, neck or on the feet, the front legs. You’re gonna be afraid that it’s something like a mast cell tumor. And mast cell tumors are bad, terrible, bad tumors. But histiocytomas are almost always in young dogs … if it’s an older dog, it’s more likely to be a mast cell tumor and not necessarily benign.

A chance to cut, a chance to cure

“And people are always under the impression that if you take (a lump) off that you’re going to make it spread or it’s going to be bad faster. And the answer is really that’s not the case. You need to go in, take it off, take good enough margins that it’s not likely to come back. But there are some masses that have little finger -like projections. And no matter how careful the surgeon is, they can sometimes be recurrent. And there’s kind of two kinds of serious masses. They’re the kind that are locally invasive and are likely to come back, but they’re not going to metastasize to other organs like the lung, like the liver, other things like that. And then there’s the bad ones that they’re just gonna spread.”

Listen in to the full episode for a complete rundown on everything from sebaceous cysts and lipomas to mast cell tumors and osteosarcoma, how to differentiate them, treat them and when to see your vet.

Marty’s pro tip is to be sure to physically locate and mark the specific lump or bump in question on the dog before visiting the vet. While generally not an emergency, various lumps and bumps should be evaluated clinically.

534 — Changing the Conversation on Cancer Diagnosis in Dogs

Changing the Conversation on Cancer Diagnosis in Dogs

Dr. Angelo Marco, DVM and Dr. Andi Flory, DVM join host Laura Reeves for an exciting conversation about advances in early cancer detection. PetDx’s OncoK9 test is able to “identify a biomarker of cancer that comes from cancer cells” from a simple blood draw, according to Dr. Flory.

Dr. Andi Flory, DVM, Chief Medical Officer at PetDX.

Flory, Chief Medical Officer at PetDx, said the OncoK9 test has the potential to revolutionize our ability to detect cancer in patients, potentially even before they start to show signs and symptoms.

While the blood test identifies a variety of cancers, it is most successful at finding the “big three:” Lymphoma, hemangiosarcoma and osteosarcoma.

“Those big three,” Flory said, “that detection rate is really high. It’s 85% and those are the most aggressive cancers that we see in dogs. So the fact that we have the potential to identify those really aggressive cancers sooner, it’s just amazing.

“The way that would kind of work, is if you think about dogs that are at high risk of cancer because of they’re getting older, for example, we know that the risk of cancer increases with age. Or because of their breed. You’re certainly aware there are some breeds that just get a lot of cancer, unfortunately. If we think about testing those individuals as a screening test, like as an annual test before they’re showing any clinical signs you know while they’re still healthy. If we can identify cancer while they’re still feeling good, then we may have a better chance of controlling it longer term.

“I think about the cases that we get almost universally when we discover hemangiosarcoma. It’s because the tumor is bleeding or it’s already spread and the metastatic lesions are bleeding and that often results in a middle of the night visit to the emergency room. It’s a snap decision. Maybe your dog looked normal that morning and then all of a sudden you’re in the ER being told your dog has a tumor on the spleen and it’s bleeding and we need to do emergency surgery and we need to do a blood transfusion and there’s really only one decision that you can make right now. It’s shocking. It’s traumatic. It’s painful for the dog. It’s all of those things and it happens so unexpectedly and it’s so emotional.”

Dr. Angelo Marco, DVM and his Border Terrier at Palm Springs Kennel Club.

“The important thing to know,” Marco said, “is that when we see a cancer signal on this test, it’s an indication of malignant tumor cells in the body right now. It’s not something that they were cured of five years ago and it’s not a predisposition test, so it’s not something that is predicting, it is something that is there in the body right now. So that really highlights the importance of going forward on that “cancer hunt” to find where is this cancer signal is coming from.”
