Which of the following treatments is commonly used for cancer?

Radiation therapy is a widely recognized treatment for cancer due to its effectiveness in targeting and destroying cancer cells. This approach uses high doses of radiation to kill cancer cells and shrink tumors. Radiation can be administered externally, using a machine that directs radiation beams at the cancer, or internally, where radioactive materials are placed inside the body close to the tumor. This method is integral to cancer management and can be used in various cancer types, either as a primary treatment to destroy the tumor or as adjunct therapy to enhance the effectiveness of surgery or chemotherapy.

In contrast, while acupuncture and nutrition therapy can play supportive roles in a patient’s overall health and symptom management, they are not primary treatments for cancer itself. Chiropractic care focuses on musculoskeletal issues and, although it may help alleviate certain pain or discomfort, it does not address the biological aspect of cancer treatment. Therefore, the distinction lies in the targeted and scientifically validated approach of radiation therapy in the direct treatment of cancer compared to the supportive roles of the other therapies mentioned.
