Get Dr. Dressler's Dog Cancer Diet FREE Many times dog lovers will arrive in my hospital and point out that their canine companion has a bump. This one is soft, kind of like very firm jello. “Doesn’t seem to be causing any pain,” they say.
Hm. Well, it could be a “fatty” tumor. This is simply a tumor made out of fat. Yes, a big glob of fat, the same stuff that makes us chubby.
Some clients have used natural means to help their dogs with these tumors. I have had my clients say they have had luck with curcumin given by mouth. Curcumin is a part of the spice turmeric. In The Dog Cancer Survival Guide, I wrote about this bioflavonoid. It can be purchased as an ingredient in Apocaps, and also by itself as a sole agent.
Many dog lovers have heard of the fatty tumors, and have been told by their vets that there is nothing to worry about. And many times, they are right.
Not every time, though.
Here’s why: first of all, not every soft tumor is a “fatty” tumor. Remember mast cell tumors, the Great Imitators? Some mast cell tumors are aggressive, life-threatening cancers. And they can feel just like a benign fatty tumor.
Your vet can differentiate between a fatty tumor and a mast cell tumor with a simple fine needle aspirate, an easy, outpatient procedure where the vet takes a sample with a needle and sends it to a pathologist. Many of us will review the slide right in house.
Another soft gooshy tumor, especially on the limbs, in called a hemangiopericytoma. This is an unfriendly tumor, folks.
Secondly, not every tumor made out of fat is truly benign. Most are, and they are called lipomas. However, a small portion of them grow aggressively. They invade into surrounding tissue. They often grow fairly quickly, over months, and expand. These are called liposarcomas.
The reason it matters is that they can become quite large. And you remove them and they will often regrow, since they are difficult to remove. You think you got ‘em, and they come back.
Take home message: if you have a rapidly growing, fatty tumor, get it out. You might be dealing with a liposarcoma, and they can be tough. Have the vet biopsy the edge, and make sure they include adjacent muscle, or the path folks may complain they don’t have enough data to make a call…
Best to all,
Dr Dressler

Dear Dr. Dressler,
I got a 5 year old female Dalmatian from Dalmatian Rescue (they got her from the pound) on January 1st. When she had her spay surgery (upon release from the pound), the vet also took out what he said was just a fatty tumor – but he said he removed it because it was in a potentially uncomfortable spot, and not to worry. Rescue gave me the rather large tumor in a baggie and told me it was a lipoma, though I saw on the surgery papers they gave me that they had denied a biopsy of the tissue – so I guess we don’t know for sure.
In the 2 months that I’ve had the dog, the lump has grown back, and then some. It’s like there’s a pouch in her chest that’s filling up with this stuff – and 2 months seems very very fast to me for it to come back entirely. It still feels fatty (though getting harder, because that pouch is filling up as it grows – that’s the way it seems to me), and I can move it from side to side a bit. It doesn’t seem to be bothering the dog, but I really can’t say, as she’s extremely quiet all of the time. I’d say it’s about golf ball size, and is tucked neatly between (and just ahead of) her armpits, exactly on the middle of her chest.
I know you can’t diagnose through an email, but I welcome any comments. I just had to treat my dear recently departed Dal 2.5 years ago for cancer on her arm, and I sure don’t want to go through that again anytime soon. But I remember when her lump showed up on her upper arm (a pretty big one, like 2/3 golfball size), it showed up pretty much overnight, and was very very hard.
thanks,
Terri
Hi Terri,
I’m going through the same thing with my 7 year old pit. Can you feel any lumps in her throat, rear of her stomach or the very back upper part of her legs. Usually lymphoma cancer will attack the immune system which will case the lymph nodes to swell, usually in the throat first. That is where we found our dogs first. Then the rest swelled. If it is just the one it could be she is fighting an infection for the lymph nodes swell because of that as well. The best thing is to take her immediately to the vet and they will check it by drawing a bit of the liquid from it. I hope it is not lymphoma, for it is extremely expensive for the chemo and no guarantees. Good luck!
Hi John,
no lumps in throat, rear of stomach, or back upper legs. She does have a few other fatty growths, but those are NOT growing.
The vet saw it 3 weeks ago and said it was fat, no problem, but it’s grown since then – not doubled, but grown.
Vets have told me before to not bother removing fatty tumors, as they may well just grow back anyways, and don’t cause the dog pain – this one just seems to be growing fast, though it still doesn’t feel like the cancer my old dog had.
I think i have left a comment before on this.. I can’t seem to find it. so i will reply again. On March 6th i had to put my baby girl, Cookie down 10yrs old. I did not know she had liver cancer.. with in minutes my vet came back and gave me the test results on Lucky (7yrs) who had a bio-opsy done the week before and found out she has Lymphosaroma (high grade). I was told she has about a month to live. Heart broken. still makes me cry. So, What should i do?? is she too far gone for treatement?? I didn’t know either of my babies had problems. no signs until it was too late. Lucky is still going. The following monday i had 17 stones removed from Lucky. lg stones. She is feeling better or at least acts happy. Cookie had started to not want to get up. I was thinking she was have pain in her knee she had surgery done about five years ago. so that’s why I thought that. Then she stopped eating… I had just had both of them to the vet the week before all this started. They were fine and happy. I guess i am at a lose for words. Just wanting to know if i could prolong lucky life. ??
Thanks,
Dar
i have a dobie with 8 tumors, one very hard on stomach, and fatty hard on rib cage causing it to expand out. vet said it was COPD. i knew something else. found a fatty tumor in lymph node under neck. several all over body. growns at night, sounds like fluid in lungs. could this be heart also? age 13. has some curvature of spine. one cloudy eye.
then, my 5 year old pitbull, am staff has one hard tumor in middle of chest. what kind could this be. frequent thirst in middle of night.
please reply if you have some suggestions. or know of a very good oncologist in washington state.
Dear Dar,
I am so sorry to hear about all of this. You should really think about “putting on your oxygen mask”, which I talk about in the Guide. It means taking some time to deal with the trauma you are experiencing before making decisions. A day or two is all it takes. You probably need to decompress and release some of the feelings you must be having.
Then you may want to ask yourself the same question. You need to decide if you want chemo and get an oncologist involved. You should think about supplements, diet, and life quality issues. You might want to get a copy of the Guide, I think it would help answer this very complex question. In the end, it comes down to you becoming comfortable being in the driver’s seat. This takes some getting used to.
All my best,
Dr D
Sharon –
Sounds exactly like my 12 year old dobie. Many lumps in various spots, especially the very large one on ribs. Recently I found on attached the skin at her throat. The vet had told us it would be to dangerous to remove them at her age. The throat one though has yet to be checked out.
Sadly, we are trying to make the decision for her. She seems to be suffering from cognitive dysfunction and does not even respond to her name. Its so hard to make a decision when you cannot tell if they are in pain….

My 12 1/2 yr old beagle has been diagnosed with a tumor on his spleen. This was done by our vet without an x-ray per my request. Blood work, exam and review of symptoms lead to the diagnosis. He began taking a steroid yesterday. In “researching” canine spleen tumors on-line, I’m finding that bloating and spleen tumor have many of the same symptoms – bloated abdomen, rapid breathing, not wanting to lay down, rapid weight loss. All of which my dog has. Are there any notable difference between the symptoms for each? My dog has had difficultly pooping and has peed in the house twice in 24hrs(not typical of him at all!), within the last month his pinna have thicken and curled(not a hematoma) on both ears. He began taking thyroid medication about 2 months ago for low thyroid. The vet said his heart and lungs sounded good, but blood tests showed anemia, very high white blood count and low red blood count. The clotting ability of his blood also measured low.
A spleen tumor seems logical, but my findings are causing me to second this. I would need to take my dog back to the vet to discuss this with the vet. Any information that you could provide would be most appreciated! Thank you!
Dear Dr.,
My story is kind of different, but the same. My 1yr old yellow lab has been taking doxycycline for a week & I just noticed a little lump the size of a quarter is protruding from her upper back leg. There is no tick or bug present. Could this lump possibly be from the medication? She was also recently at the vet & got a series of shots. Could this be a cause of the lump? It is soft & does not bother her. I am so worried! Please help!
Dear Sara,
In the same way that if you awoke one morning and found a lump on your body you would likely get it checked out, the best thing to do is bring your dog to the vet. Could be nothing, could be something. No, doxy would not be a typical reason for a single lump. A local vaccine reaction could be though. Regardless, get it checked.
Best,
Dr D
Dear Dr. Dressler,
We have a 4 y/o Jack Russell/Chihuahua mix. He began growing a bump on his armpit/chest area with weird hair follicles. In June 09 we had it surgically removed because it was growing quite large. The biopsy came back benign. Two days ago we had him operated again because it was again large and hindering his walking. This time around the doctor had less luck and only removed 1/3 of the growth. He stated it had infiltrated too many muscles and was afraid to cause permanent damage. I know we will not have our dog operated on again, but don’t want to give up. I am desperately searching for an alternative to surgery. In what I have read they have mentioned radiation therapy. My vet stated that would not be an alternative. I can’t just give up. I need to know that I have looked into all possible alternatives. Can you please make any suggestions where I can find some answers?
