Not only do Cancer Cell Lives Matter, but Cancer Cells are under threat by White Supremacist Blood Cells. White Supremacist Blood Cells viciously kill innocent cancer cells jogging through the bloodstream as they peacefully try to spread genetic diversity throughout your body.

It's very important to fight off the White Supremacist Blood Cells, and the best way to do that is with HIV/AIDS, which celebrates diversity by targeting the Fascist White Supremacist Blood Cells. HIV-infected cells pretend to be "Fellow White Blood Cells" but secretly have a globalizing agenda to protect innocent cancer cells and end White Blood Cell Supremacy.

See this comic.

Well, the left has decided that White Lives don't Matter, and that it's "White Supremacy" if someone dares to say that (never mind that if we had REAL White Supremacy, "White Lives Matter" would be state-enforced!).

So the left can easily say that (White) Babies Cells don't matter, etc.
