Hint: X-rays and gamma rays are a type of radiation that target malignant cancer cells to kill them and shrink tumors. Cancer treatment is carried out through multiple options, by using drugs, radiation, hormones, surgery, and so on.
Complete answer:
- Radiation therapy or radiotherapy is a type of cancer therapy that uses ionizing radiation such as X-rays and gamma rays.
- The ionizing radiation damages the DNA of the cancerous cells leading to their death. In order to prevent or alleviate damage to the normal cells, the rays are shaped and aimed precisely at the tumor tissue.
- Radiotherapy is combined with chemotherapy, surgery, immunotherapy, and/or hormone therapy for treatment.
Additional Information: - Chemotherapy is a type of cancer therapy that uses anti-cancer drugs to cure the disease or to prolong the life of the patient.
- Surgery is the oldest technique of cancer therapy. It involves the removal of the tumor and the tissue surrounding it.
- Immunotherapy in cancer involves stimulating the immune system to fight against and grow strength against cancer cells, by exploiting the presence of tumor antigens.
- Hormone therapy or endocrine therapy uses specific hormones as well as hormone inhibitors to treat cancers such as breast and prostate cancer.
So, the correct answer is ‘radiotherapy’.
Note:
- Hormone therapy for prostate cancer is known as androgen deprivation therapy.
- Radiotherapy is carried out by a radiation oncologist.
- Radiation oncology is different from radiology, where radiation oncology or radiotherapy is the treatment of cancer using radiation and radiology is the usage of radiation in medical images and diagnosis.
