Do the cancer cells take in more of the Boron than normal cells? Or is there some reason that only the cancer cells take up the Boron.

If it’s the former, then normal cells are going to be damaged too. Though perhaps not as bad.

From the article--When those boron-infused cancer cells were exposed to neutrons, a subatomic particle, the boron atom shattered and selectively tore apart the cancer cells, sparing neighboring healthy cells.

Looks like a win-win situation.

The cancer cells grow faster than normal cells, meaning they have to consume more material. Like many cancer therapies, this one is based on the differential growth rate between normal and cancer cells. I'll speculate a bit here and say that the researchers probably fine-tune the amount of radiation, so that normal cells with n amount of boron are not affected, while cancer cells with 2n quantity of boron are.
