compare the benefits and drawbacks in ionising radiation.
- you need to think about the advanages and disadventages and decide if the advantages outweigh the disadvantages.

Answer:
Radiation therapy uses high-energy particles or high-energy waves to kill cancer cells. Cells grow and reproduce in order to create new cells and replace cells lost to damage and aging. Cancer cells reproduce faster than normal cells and lack the controls found in normal cells. The high energy particles (or waves) kill cancer cells by causing damage to their genetic information ( DNA). DNA contains the information used to control cell growth and division.1
Radiation is a localized therapy, the high energy beams are targeted directly at the cancer. Efforts are made to avoid as many healthy cells as possible. Because this therapy is focused on a specific area of the body, it is not useful in treating cancers that may have spread to other places. Radiation therapy is used to- cure or reduce early-stage cancer, prevent cancer from returning (recurrence), treat symptoms due to advanced cancer and treat cancer that has come back.1
Chemotherapy involves using drugs to treat cancer. Unlike radiation, which is used to treat cancer in a specific region of the body, chemotherapy drugs spread throughout the body. It is used to treat tumors that can’t be removed by surgery, cancers that have spread from the original tumor to other parts of the body, and when doctors don’t know if a cancer has spread or not. Like radiation therapy, chemotherapy drugs target the division and activity of cancer cells to kill them.2
Chemotherapy is used to cure cancer, reduce how much a cancer spreads, and to reduce the pain caused by some cancers. Because the drugs used in chemotherapy affect both healthy cells and cancer cells, doctors must give a specific amount of drugs (calculated for each patient) that maintains a balance between killing cancer cells and protecting healthy cells.3
Explanation:
Radiation therapy (also called radiotherapy) is a highly effective cancer treatment with wide-ranging uses. Radiation therapy leads to cancer cure in many patients (either alone or with other treatments) and relieves symptoms or prolongs survival in more advanced cancers.
