Are the melanomas a real health threat? Anything you do about it?

Yes melanomas can be a health threat and it is best to discuss them with your vet when they appear.

There is no known way to prevent melanomas.

There is a theory that appys that go grey may have a lesser chance at melanomas. Something to do with the appy patterning and how it is produced/expressed. I'll have to find the exact 'why' they think this when I can get on an actual computer and not my phone

Most grays will end up with melanomas at some point in their lives but from my understanding, the majority of them really aren't life threatening. Most grays that get them just get unsightly growths, most commonly around their genitals, under the tail, and between the hind leg on the udder/sheath. Some others, like my Dobe, get them on odd places like their back or face. I've heard mixed reviews about having them removed...some say to make sure and remove them asap to prevent spreading, others have said that if you remove them, the site of the surgery to remove them is more likely to have them grow back. At this point, I am of the mind that you should remove them when you can, as quickly as you notice them. I had 2 of Dobe's removed a couple of years ago and have not seen any sign of problems from the removal. When we finally get a freeze and kill all the flies, I will be having 3 more of his removed.

We had an old mare that we called Frosty that had them horrible under her tail. While they were extremely ugly, she remained healthy into her late 20's, and this was back in the 80's when she finally died, before the medical advancements and all that.

Can someone post a pic of what one of these melanomas looks like? Because I don't even know what to look for on our boy!!!

And does anyone know, when you opt to have them removed, does the vet cut them off or freeze them off like warts?

And one more question for those who know, our boy's skin is black....r there light skinned grays and dark skinned grays? And why would a horse with black skin be more apt to get skin cancer than a pink skinned horse?

Greys have dark skin, like most other colors. They will only have pink skin if--they are a double creme dilute, champagne (where it will then have freckles) under the grey or if there are white markings to cause the skin to be pink...and I would assume if the horse were a pearl or pearl/creme under the grey you would get the pumpkin colored skin (which may be possible with single creme dilutes as well--have seen several with this color of skin that did not have pearl or even champagne)

Melanomas look...warty almost...lumpy bumpy--for the most part.

You can google image Equine Melanomas and it'll come up with a host of pictures for you to view.

Most definitely.

Grey horses have a natural suppressor that lessons the chance of melanoma metasticizing, so although they have a substantially higher incidence of melanoma, most of their melanomas do not metasticize. However, for those that do metasticize, the melanoma is just as serious as it is in a non-grey horse.

In direct answer to your question, as with any cancer that metasticizes, melanoma can be fatal. In addition, even if it is a grey horse and the melanoma doesn't metasticize, it can get very nasty with secondary infections and complications - particularly as it occurs often in the genita, anal, and mouth areas...

^^Exactly.

Beau, the only ones I have good pictures of are the ones that I had taken off of Dobe a couple of years ago, they didn't get nearly to the point of the pic that black cricket posted.


Here is a better picture that really shows where they are at (I also circled them just for ease of finding...)


And here are the 2 that have come up on his face recently. He has another, larger one on his back but I don't have a good pic of that one and it is now mostly hidden by winter woolies.

Wow! I have learned a lot!!

Got to lookin at my mare today, and I found a weird small hairless patch on her shoulder with these weird bumpy-wart like things. Definitely going to get the vet out next week.
