How Dog Cancer Became a New Species (CTVT)

You probably think of cancer as being not infectious, right? One of your cells made a pro gamer move and started dividing uncontrollably, but it’s not like that could become someone else’s problem. I mean, I can’t even get a kidney transplant, gaining superhuman urine production with the power of three kidneys, without needing drugs to stop my body from rejecting it.

But it turns out there actually are some types of cancer that are not only infectious, but become plagues in their own right! Lets talk about that.

Approximately 11,000 years ago, there was a dog.

That dog developed a tumor. A cancer.

This dog’s genetic makeup still exists to this day through the cancer that mutated from it. Transmissible to other dogs.

I’ll remember you.

I was talking on Discord a bit ago (as one does) about whether Space Marines are a separate species from humans (not really), but then thinking about it later, about what the fuck they are biologically -- they’re parasites, of course.

Or at least, their gene-seed is.

Each Legion’s gene-seed is an asexually reproducing lineage that uses a combination of social and biological manipulation to force its human hosts to reproduce and spread it, both inside their human bodies and in the labs of the Apothecarion.

“Parasite” is a bit of of a value judgement, of course. The Space Marines themselves, if they didn’t find the whole discussion heretical and blasphemous, would probably describe the relationship as mutualistic. They benefit immensely! They’re bigger, stronger, more durable, and live longer (if no one kills them)!

(And if they don’t die in the implantation process, of course. A roughly 90% death rate is a helluva fitness cost on both the human hosts and the space marine gene-seed.)

But... the gene-seed also seems to sterilize them[1], and that caries a lot more weight in biology than physical strength or longevity on its own. Space marines’ enhanced bodies don’t work to reproduce human children; instead they grow new gene-seed to implant into more humans. 

That’s a little reductive for a social species, of course. Sure, humans with gene-seed implanted into them don’t reproduce directly, but surely they increase the survival and reproduction of other humans sufficiently to make up for it!

Which may be true in canon [2] and is more defensible as a biological argument than as a moral one. [3]

But given that (a) space marine gene-seed carries its own genetic code which (b) it requires the help of its human host and his community to reproduce (c) at the direct expense of the human host’s own life (most of the time) and reproduction (nearly always)... yeah, I think parasite is accurate.

[1] Canon’s not entirely consistent here, but certainly Space Marines rarely if ever have biological children. [2] Hard to measure that sort of thing in a fictional universe with wildly varying made-up population numbers. [3] Do the numbers add up? Who knows, maybe. Does this justify anything the Imperium is doing? Whole different question, and no.

Fucked up that canine transmissible venereal tumor could arguably be called a "single-celled parasitic mammal". What a creature.

1, 3, 12, c!

c: answer in a completely different typing style/cadence

Oh boy

1. How are you?

I am doing swimmingly well, like an arthritic duck in warm bathwater.

3. Who would win in a fight between all your ocs/rpg characters?

Cooter would best anyone in hand-to-clawed-foot combat, his athletic prowess is matched only by his need to be a putrid little toe-snatching aberration.

12. Someone invites you onto their podcast. you have to give an hour-long lecture about any topic of your choosing. What would you pick?

Well I believe I would select the Canine Transmissable Venereal Tumor, as it poses a lot of interesting questions about cancer and evolution in a way that encourages "low brow humor".

#thanks skylar!! this is a fun game #jabberjos

[countrylanes]

the one dog from which canine venereal transmissible tumor originated has been dead for 6,000-11,000 slutty, slutty years

#m #or maybe it's been alive for 6000-11000 years his cells are still out here

Male Dogs are More Prone to Contagious Cancer on Nose or Mouth: Here's Why

Sniffing or licking female dogs' genitalia- a common site of Canine Transmissible Venereal Tumor (CTVT) can spread this unusual cancer to the nose and mouth of male dogs. http://dlvr.it/STKyYf

Male Dogs are More Prone to Contagious Cancer on Nose or Mouth: Here’s Why

Male Dogs are More Prone to Contagious Cancer on Nose or Mouth: Here’s Why

Researchers think this is because of behavior differences between the sexes: male dogs spend more time sniffing and licking female dogs’ genitalia than vice versa. What is Canine Transmissible Venereal Tumor (CTVT)? Canine Transmissible Venereal Tumor, or CTVT, is an unusual cancer – it is infectious and can spread between dogs when they come into contact.

I’ve been in the monster hunter fandom for many years now and I’ve heard a lot of theories and headcanons. But this is the first I’ve heard of cancer deviljho. Is this a personal headcanon or is it one that exists in the greater fandom?

This is a personal headcanon I made a few days ago!

The idea is that during the last ice age a genetically pure jho died and it had a somewhat functional teratoma that ate its way out and started living on its own.

Jhos as cancer colonies would explain why their various organ systems are failing and why they don’t have any sexual organs. Instead of sexual reproduction, when a jho gets big enough sometimes some of its cells become genetically distinct enough to become a hypertumor, and either the jholings slough off or all the jholings exhaust the parent jho of resources and it dies and they break off to live on their own.

In real life there are times when cancer colonies outlive their original parent body and in some rarer cases still continue to evolve and eventually become a distinct species of their own (such as transmissible tumors).

But obviously Deviljho can’t actually be a walking teratoma. It’s too functional to be a cancer. Cancers are too chaotic to be able to function as anything other than a parasite or small colony.

But some people on the UHC server really like the idea.

Nobody: Me: Must draw... forbidden dog...

Canine transmissible venereal tumor (CTVT) is one of three transmissible cancers documented in mammals, the other two being devil facial tumor disease in Tasmanian devils and contagious reticulum cell sarcoma in hamsters

The most interesting thing about this pathogen is not how it’s spread (i e via mating), but its genetic makeup and where it came from. To put it bluntly, genetically speaking, CTVT is a dog. A single, 6000 year old immortal dog. You see, CTVT cells still carry the DNA of patient zero, despite acting more like a pathogen

I just think “ghostly cancer dog” sounds really sci fi and I wanted to draw an artistic representation of it, combining reconstructions of hunter-gatherer dogs (which are probably pretty close to what this dog would’ve looked like in life) with ghostly qualities. This is probably the most savory depiction of CTVT you’ll see, it’s really quite grisly in action I’m afraid

This idea was born while reading about Canine transmissible venereal tumors, but I’ve decided to call it “Doggoth”

canine transmissible venereal tumor is literally so fucking cool. living cells from a single dog that lived 6000 years ago infect other dogs as a sexually transmitted tumor. it sounds a bit less strange when you really break it down and view it in the wider context of transmissible cancers but its still like, a single dog has achieved a form of immortality by an unbroken line of its cells surviving parasitically for six millenia.

[ask-a-vetblr]

hello! i hope this wasnt asked before, because i have no idea how to even search for it. i once heard of a Dog Disease Thats Actually A Dog. as in... it has the dna of the original dog that developed it? or something of the sort? intense googling only brought up generic "top 10 most common dog diseases" articles. thank you for your time :)

Hello, @release-the-hound here! I believe you are talking about Canine Transmissible Venereal Tumour. It’s one of only a few naturally occurring clonally transmissible cancers in the world. That means it’s a sexually transmissible cancer. It is sometimes known as Sticker’s Sarcoma. 

If you’d like to know more about this fascinating disease, this article gives a brief overview. Since it's such a unique disease there are also plenty of scientific papers on the matter.

I would recommend:

Murchison, E. P. et al. Transmissible dog cancer genome reveals the origin and history of an ancient cell lineage. Science 343, 437–440 (2014)
