how does cancer not always relapse after radiation treatment

Cells are tiny and there are billions upon billions of then in our body. If cancer starts to form, how is it that in some cases, treatment can kill every single cell and cure a person of cancer? Isn’t leaving even one cancerous cell dangerous as it’ll multiply infinitely?

Not all cancer cells are equal. If the radiation kills the most “cancerous” of the cancer cells, the rest of the tumor can be destroyed by the body.

Heterogeneity is the technical terminology for this.
