Answer

Brief Explanations:

Radiation therapy for cancer works by damaging the DNA of cancer cells. High - energy radiation can cause breaks in the DNA strands, which stops the cancer cells from growing and dividing. It doesn't work by cooling or heating cells in the ways described in the options. But among the given options, radiation is not about cooling or strengthening non - cancerous cells, and its main target is cancer cells. It can be thought of as 'weakening' cancer cells by damaging their DNA. Radiation doesn't heat up non - cancerous cells to strengthen them either. The closest conceptually is that it affects cancer cells in a way that weakens them.

Answer:

It heats up the cancer cells and weakens them.
