So if dogs have a caner that spreads deom dog to dog...
Do humans have anything like that? If we did would this not cause a panic?

Per Wiki:
> There are no reported human cases of clonally transmissible cancers that can independently survive and be transferred in the manner of CTVT and DFTD. However, instances of one human passing cancer cells to another through physical contact have been reported. These cases typically involve organ or hematopoietic stem cell transplants or cancers transferred from a pregnant mother to her fetus.[66] The difference of these incidences from a true clonally transmissible cancer, however, is that the cases of human transfer were one-off events — the actual tumor did not have properties allowing it to be continually transferred throughout the population, and therefore the tumor clone went extinct with the death of the host individuals.
> To clarify, several cancers can be caused by infectious entities; cervical cancer, for example, is the work of HPV, a sexually transmitted virus.
Oddly, the main panic we see around HPV is anti-vaxxers going after the Gardasil vaccine.
I don't know much about anti vaxers. I just remember something about how it causes autism (they think). And often diagnosis is around the time early childhood vaxination is done.
Sonmy question is what does a late child vax for HPV do (in their words).

For the family of that girl and her close circle that is the image they have of the vaccine. I'm not saying the vaccine cause paralisis. I'm saying that for her it was the cause, they still don't have another explanation (no gillan-barre, nor wierd infection). Thats why in Colombia just a few people will allow to get that vaccine, out there you will find few cases like the one of my friend, but enough to make most woman reject its aplication.
Its just a view from that population perspective and why it impacts on the acceptance of the drug.

> “Our results show that Guillain-Barré is not occurring more often after HPV vaccination than it does in the general population.”
Side note: Even if the vaccination caused all 36 cases described in a two-year period, and even if that were elevated from the normal incidence in the unvaccinated population, HPV causes thousands of deaths annually from cervical cancer. Public health should be a matter of statistics, not anecdotes.
Most probable cause? That’s a bit of hyperbole without extraordinary evidence.
Similarly, a cancer that started in a specific dog ended up evolving to survive in different animals.
>To clarify, several cancers can be caused by infectious entities; cervical cancer, for example, is the work of HPV, a sexually transmitted virus. But in those cases, the cancer itself is not infectious and cannot spread. CTVT is different: Each cancer cell is a free-living parasite that can set up another tumor on another dog.
HPV can also (rarely) cause cancers of the throat and penis.

Put another way, HPV is a virus whose effects can cause cancer. That is, it causes mutations in _your own_ cells that cause them to become cancerous.
CTVT is essentially a parasitic cell line — not your cells hopping a ride on you.
