White horse more prone to cancer?

So my close family friend owns a full white Percheron.
She has had him for about 25 years and has recently just found out that he is full of cancer :'(
Are white horses more prone to cancer than other colored horses?

Just want your opinions! :)

Greys are more prone to melanomas (inside as well as out) and most die with them but not always because of them. I wouldn't choose to have a grey horse for that reason (my last arab died of them as did my friend's andalusian cross).

From what I've read, gray horses are more prone to melanoma (skin cancer) than other others, but any horse can get melanoma.

I have a cremello and a gray that we just purchased this year. My vet recommened using fly spray with sun block in it or spf 80 lotion on their noses, hind ends, etc because they are more prone to developing skin cancers. I would guess they are more prone to cancers, similar to how albino animals are more prone because of the lack of skin pigment.

The melanomas greys get are often internal ones and not related to sun exposure. You often see them around their docks.

Yes, barrelracer. Your friends "white" percheron is technically a gray and grays are prone to Melanoma.

I knew a vet that used to say "If it's gray and lives to be 25 it WILL have melanoma." .. (Don't know how true THAT is...)

Also, the increased risk for melanoma seems to be associated specifically with the gray gene- your cremello (which has lightly pigmented skin, unlike the skin of a maximum sabino, for example) isn't at any higher risk for melanoma than any other non-gray horse.

It is. Being black or red based, and having agouti or not (Even on red bases) also effects the rate that grays get melanomas.

I have a maximum sabino paint who is pink skinned head to toe. I keep lots of sun block on him. He is 13 now and I havent really had any skin problems other than an occasional sunburn. He doesnt get them as off then as I keep his face covered with a fly mask and am very proactive about sun block. But I haven't had any cancer problems knock on wood . But I have heard that white faced horses who do not have eyeliner are prone to eye related problems and cancers which is why some people tattoo eyliner though mine has it naturally.

So when you say " eyeliner" is that like a grey stripe around the white ? Or around the eyes?
