Chemo is taken with the purpose of killing cancer cells without removing them. People talk about parts of tumors with living cells as alive, and part of tumors that have dead cells (whether through strangling their own blood supply, or chemo, or whatever) as dead.
The language of “when life begins” is using a specific and unusual definition of “life”, that I think has more to do with the concept of a soul than with any of the more common definitions of “life”.
