Final answer:
Children undergoing radiation therapy for cancer may experience damage to rapidly dividing cells in their bodies, but the therapy targets cancer cells more effectively.
Step-by-step explanation:
Children being treated for cancer with radiation therapy are likely to experience damage to rapidly proliferating cells in their bodies. These cells include bone marrow, skin, reproductive organs, and intestinal lining. The harmful effects of radiation exposure can result in issues such as the lack of red blood cell production, congenital disabilities, and damage to the cancer cells. However, the advantage of radiation therapy is that cancer cells divide faster than normal cells, making them more susceptible to radiation and allowing for selective killing of the cancerous cells.
