- Retric 7y agoNo, 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.
- astura 7y agoThe 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.

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.
