The Most Common Cancers in Cats

2023-08-14

Did you have any idea that November is all about Pet Cancer Awareness? That's right, we're shining a spotlight on this important cause. So, get ready to join the forces of the Animal Cancer Foundation, and let's make some noise to raise awareness about this health condition that affects our furry friends.


Now, here's the deal, one in five pet cats and a whopping five in ten pet dogs get hit by this cancer thing. It's a tough battle for them, but we can make a difference by getting the word out and supporting those pawsome initiatives.


So, let's show our love for our four-legged buddies and get involved this Pet Cancer Awareness Month. Together, we can make sure our pets get the care and attention they need. Spread the word, lend a hand, and let's make November a month of hope, strength, and unity for our beloved fur babies. Oh, and don't forget to give 'em some extra belly rubs too!


What Is Considered Cancer?


Alright, let's dive into a little Cancer Lesson. So, picture this: your cat has been her energetic and overbearing self for the past week or so and you take her to the vet. As you are talking about the bloodwork for your feline partner the vet mentions something called "Neoplasia." Now, what the heck is that? Well, it's basically when your cells or tissues in the body go all haywire and start growing out of control. The word "cancer" gets thrown around a lot, but hold on a second, not all neoplasms are cancerous, okay?


So, you've got this abnormal growth, and we call it a neoplasm or a tumor. Now, the interesting thing is, tumors can be of two types: benign or malignant, eh? The benign ones take it easy, they grow slowly, and they're kinda polite, you know? They might push their way around a bit but don't invade their neighbors or spread like wildfire throughout the body.


Now, here's where things get serious, bud. The malignant tumors are the ones you gotta keep a close eye on. They're like a wild card, totally unpredictable. They can grow at different speeds, sometimes even faster than a jackrabbit on rollerblades. Plus, they're real invaders, pushing into the surrounding tissues like they own the place. And the worst part? They can spread, or as specialists say, "metastasize," to other parts of the body. Not cool, right?


So, this whole cancer business falls under the purview of Oncology, just like the human side of things. Oh yeah, you heard me right, there are veterinary Oncologists out there. These are the vets who've gone the extra mile after veterinary school, getting all that fancy additional training and a beautifully painted diploma on their cabinet wall. When we refer to veterinary oncologists in the US they're certified by the American College of Veterinary Internal Medicine (ACVIM) in oncology. These folks are like the cancer-fighting superheroes of the vet world, working hard to help our furry friends battle this nasty disease.


Common Cancers in Cats


The three most common cat cancers are lymphoma (blood cancer); soft-tissue sarcoma (such as cat lung cancer, breast cancer, and throat cancer), and squamous cell carcinoma (cat skin cancer, cat mouth cancer/oral cancer).


Lymphoma


Lymphoma is like a wild blood cancer party where those lymphocytes start multiplying like there's no tomorrow. These little guys are immune cells, brewed up in the bone marrow, and they're found in the blood and lymph tissue. Talk about pet bodyguards against infections!


In cats, lymphoma likes to crash the party in places like the intestines, nasal cavity, lymph nodes, kidneys, and liver. Not the best guest list, if you ask me. But here's the kicker, before we had the FeLV vaccine, that feline leukemia virus (FeLV) was one of the main culprits behind lymphoma in our furry pals. This nasty virus spreads mostly through saliva, but you can find it hanging around in urine, feces, and milk too. Do not fret my friend, with the FeLV vaccine on our side, we're throwing a wrench into its plans. Not only does it protect our cats from FeLV, but it also indirectly shields them from certain types of lymphoma. Now, that's a win!


Here's some more good news, folks. Lymphoma might be a bit of a party crasher, but it's also one of the most treatable cancers out there. That must be music to the ears of cat owners worldwide! Chemotherapy is the go-to for dealing with this pesky cancer, and you know what? Cats actually handle it pretty darn well. They get to keep on enjoying a great quality of life while giving lymphoma the boot.


Here's the icing on the cake, studies show that up to 75% of cats treated with chemotherapy hit that sweet spot called remission. Isn't that awesome? But hey, like any party, it depends on the location and the type. But overall, we're getting some impressive results.


Squamous Cell Carcinoma in Cats (SCC)


Let's talk about another sneaky villain in the world of feline health: Squamous cell carcinoma, or SCC for short. It's like a crafty skin cancer that likes to set up camp on those exposed areas, like the ears, nose, and eyelids. Do you want know something interesting? White cats in sunny climates are like magnets for this troublemaker. Can't blame them, the sun's pretty enticing, no?


But here's the good news, if we catch this solar-induced cat skin cancer early and give it the boot, the prognosis is lookin' pretty darn good. Prevention's the name of the game too. Keep those kitties indoors, away from the sun's ultraviolet rays, and we'll be winning this battle.


Now, brace yourself, because cat skin cancer isn't just about those exposed areas. It can also make its way into the mouth, and there we have oral SCC, which makes up a solid 10% of cancer cases in cats. And let me tell you, SCC is no pushover; it's an aggressive one, especially those oral tumors. Despite our best efforts, the prognosis for those is not great.


Fibrosarcoma in Cats


Fibrosarcoma is another tricky disease that can mess with our feline friends. It's like this fierce tumor that comes from fibrous connective tissue, and it means business, let me tell you. Sometimes this fibrosarcoma pops up right at the site where our kitties got those essential vaccines and medication shots. It's called feline injection-site sarcoma, or FISS for short. This thing has been linked to all kinds of injections: vaccines, corticosteroids, antibiotics, insulin, you name it.


But hang on, don't go running for the hills just yet. This complication is pretty darn rare, eh? We're talking 1 case per 10,000 to 30,000 vaccinations, according to the smarty pants who study these things. So, our vets, they're on the ball, always looking out for our furry pals. They'll tweak the vaccination schedule and pick the right spots for those shots. Oh, and here's a pro-tip: they might suggest specific vaccines that don't have aluminum, 'cause that seems to crank up the irritation at the injection site and boost the risk of FISS.


But here's the scoop, my friends, it's a bit of a puzzle because there might be a bunch of factors in play, like dosing and genetics. We're still figuring it all out, but our veterinarians are all over it. If this fibrosarcoma does show up, it's time for action, no messing around. Aggressive surgery's on the menu, maybe throw in some radiation or chemotherapy for good measure.


Preventative Care For Your Cat


Alright, cat enthusiasts, let's give our feline partners the best shot at being those four lucky ones who dodge cancer's stats! Here's the lowdown on how to be their ultimate wing-cat:


Number one - regular vet check-ups! Schedule those visits like clockwork, folks. Early detection is key, and it could mean the difference between a catnap and a real catfight with cancer.


Next up, a balanced diet is the way to go. Give 'em the good stuff, tailored to their age, size, and health needs. Talk to your vet to make sure they're getting all the right nutrients in purr-fect portions.


Keep an eye on their waistline too! Obesity's a big no-no. It can lead to all sorts of health issues, including cancer. So, a little workout and some portion control will keep 'em feeling frisky.


Keep your little fluff ball indoors, okay? Going outside might seem fun, but it comes with risks like toxins, infections, and injuries. Keep 'em safe indoors to reduce those cancer odds.


Oh, and secondhand smoke? Not cool. Studies say it could up their cancer risk, so keep your home smoke-free for their sake. Keep in mind that cat asthma is a real thing.


Sun-worshipping might sound nice, but it's a risk for cats with light-colored fur. Too much sun can lead to skin cancer, so be smart and limit their sun time, especially during those peak hours.


Now, let's talk household products. Some can be a real bummer for cats and could increase their cancer risks. Go for pet-safe alternatives whenever you can.


And you know what they say - a healthy mouth is a happy cat. So, keep those pearly whites in tip-top shape with regular dental check-ups and good hygiene. It might just help ward off certain cancers too.


But hey, here's the thing — even with all these preventive measures, cancer can still sneak in. So, keep a close eye on your feline friend. If anything seems off or they're acting strange, don't hesitate to call in the pros. Your vet's got your back and can give 'em the personalized care they need.


Let's keep our whiskered pals healthy, happy, and living their best nine lives possible! Stay vigilant and let's tackle any challenges together. You're the cat's meow, and your fur baby knows it!


Signs of Cancer in Cats


You know, just like us humans, our furry little pals can develop neoplasia too. It can strike any organ or tissue in their precious bodies. And let me tell you, the signs you might notice can be quite the mixed bag, depending on which part is affected and how severe the neoplasia is. If you happen to spot any of these signs in your four-legged companion, it's time to consult your veterinarian pronto:


1. Abdominal swelling;

No one likes a bloated tummy, even our fur buddies.

2. Bleeding from the mouth, nose, or anywhere else it shouldn't be coming from;

That's never a good sign.

3. Difficulty breathing;

Just like us catching our breath after a sprint, our pets need to breathe easy too.

4. Difficulty eating;

Food is life, and if they're having trouble with it, it's a red flag.

5. Lumps, bumps, or funky-colored skin;

Keep an eye out for any strange growths or discoloration on their adorable bodies.

6. Non-healing wounds;

We all know how cuts and bruises heal, but if it ain't healing, something's up.

7. Persistent diarrhea or vomiting;

Ugh, we've all been there, but if it's sticking around for our pets, it's time to take action.

8. Sudden changes in weight;

Just like us fluctuating on the scale, sudden weight changes are worth looking into for our pets.

9. Unexplained swelling, heat, pain, or lameness;

If they're showing any of these signs, it's better to play it safe and get them checked.

10. Visible mass/tumor;

If you can see or feel something abnormal, don't wait around.


Sometimes, these signs can be related to non-neoplastic conditions too. But don't take any chances! Get your fluffy buddy to the vet ASAP. Early detection could make all the difference and you must remember that neoplasia is often treatable. So, don't delay — get your pets the best care possible!


How is Cat Cancer Identified?


We take this itty-bitty needle with a syringe, give it a little suction action, and bam! We snag a sample of cells right from the tumor, slap 'em onto a microscope slide, and send them off to the expert, our veterinary pathologist. This is called - fine needle aspiration, or FNA for short.


Now, sometimes, those FNA results might be a tad unclear. In those cases, we might need to roll up our sleeves a bit more and go for a biopsy. It's like a surgical scoop-out of a piece of the tumor. After that, we hand over these tumor bits to our trusty veterinary pathologist again, and they go full-on microscope mode with histopathology. What is Histopathology you ask? It's like detective work on a cellular level. It helps us nail down that diagnosis and gives us some clues about how that sneaky tumor is gonna behave.


Your vet might dive into some extra testing, like this fancy thing called immunohistochemistry. Picture this: they use these tiny warrior molecules called antibodies to go all detective mode on tissue samples. These antibodies sniff out specific antigens, giving us some rock-solid intel about cancer types or other pesky diseases. And here's the best part, this immunohistochemistry stuff gets us some seriously specific results. It's like having a GPS for pinpointing what we're dealing with. With this kind of intel, we can really get to know that cancer. And that's not all, it helps us whip up a customized treatment plan, tailor-made for our furry pal.


So, whether it's FNA, immunohistochemistry, or the full-on biopsy deal, our veterinary dream team is on the case, sniffing out those tumor mysteries and making sure we get the whole picture. Stay curious, stay vigilant, and let's keep those furry friends in the best shape possible!


Cat Cancer Treatment


Treatment for neoplasia in our furry friends can be a bit of a mix-and-match game. We might have to use surgery, chemo, radiation, cryosurgery (freezing stuff), hyperthermia (heating things up), or even immunotherapy. It's like a pet treatment buffet!


But here is the cool part — our little buddies often handle chemo way better than we do. Tough little critters, are they not? And it's not just about zapping the nasty stuff, your vet might suggest dietary tweaks or other therapies to help them cope better with the whole shebang. Oh, and let's not forget pain management - that's crucial for their comfort during the process.


The good news is, neoplasia is often treatable. Early detection is the name of the game, and it sets the stage for your vet to give your pet top-notch care. Once you got the diagnosis, the vet's gonna chat with you about the best treatment options available and what comes with each — the risks and the side effects.


Sometimes, though, neoplasia can be a tricky beast. Some types can be cured, while others can only be managed to keep them in check and ensure your pet's comfy and happy as can be. There are a couple of key factors that decide how successful treatment's gonna be:


First, the stage — how big it is and how far it's spread in their little bodies. Then there's the type — that gives a hint at how they'll respond to therapy and if it's likely to spread its tentacles elsewhere.


No set-in-stone rules here, my friends. But let me tell you, treatment can be a real winner for many pets dealing with neoplasia. There's hope, alright!


Now, when it comes to these growths, the good news is that benign ones are usually easier to handle. But don't let your guard down — catching any type of neoplasia early is like hitting the jackpot! It ups the odds of successful treatment big time.


But hey, don't underestimate those benign tumors. They might not spread like wildfire, but they can still be sneaky little troublemakers. Like brain tumors — sure, they're often benign, but they can play havoc with the surrounding brain tissue, and that is not good as it is life-threatening.


Now, some of these neoplasms, especially the more aggressive ones, can be really stubborn. Can't always cure them, but that doesn't mean we give up the fight. Treatment can still buy our furry pals more time and give them a better quality of life. And that's what it's all about — making sure they're happy and comfortable, no matter what.

Cancer in Cats — When to Euthanize?


But hey, let's be real here. Sometimes, despite all the efforts, treatment might not be the answer. It's a tough call, but euthanasia could be considered if things aren't looking too rosy. Cost, type of neoplasia, and your pet's quality of life all come into play when it is time to make a decision. Talk it out with your vet, weigh the options, and make the best decision for your beloved pet and your family.


Remember, our furry pals are always there for us, and it's up to us to give them the love and care they deserve. Stay strong, stay positive, and let's tackle this together.
