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?

Without having read the article, and not being a biologist ... is this anything like HPV/Cervical cancer for humans?

  No, this closer to the HeLa cell line. Initially it took significant effort to grow these cancer cells, but after evolution in a research environment now they easily contaminate other experiments. https://en.m.wikipedia.org/wiki/HeLa https://en.m.wikipedia.org/wiki/HeLa Similarly, a cancer that started in a specific dog ended up evolving to survive in different animals.

  The article addresses this: >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.

  The third paragraph: > 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. 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.

From the article: > 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.

  Don't you get HPV vax way late in life. Like waay after autism diagnosis. 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).

    Vague, conspiratorial claims of "vaccines are just dangerous" and religious conservatives claiming making sex safer encourages promiscuity. https://www.theguardian.com/science/blog/2016/jan/11/why-is-there-opposition-hpv-vaccine-cervical-cancer https://www.theguardian.com/science/blog/2016/jan/11/why-is-...

    Anti-vaxx reasoning can be repackaged for any circumstance. In this case, they look for rare, tragic outcomes in teenagers the proper age for the HPV vaccine, look for temporal correlation, and blame it on the vaccine.

  There are a lot of questions around Gardasil vaccine. I have a friend that had the vaccine and she has her body paralized 3 years for 3 years now. She's 17 years old, living in a bed and suffering depression. I know there could be another cause for her paralisys but the vaccine is still the most probable cause, so having the vaccine was her worst decision of her life.

HPV seems to be a similar disease.

  I actually don't think so. HPV is a viral infection that causes cancer. CTVT is a cancerous tumor that is itself the vector of infection.

No, nothing like this has ever been observed in humans. 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.
