Which of the following is not a common type of complementary treatment?

Surgery is not considered a common type of complementary treatment. Complementary treatments refer to practices that are used alongside conventional medicine to enhance patient care and support overall well-being. These can include nutritional strategies, acupuncture, yoga, and other holistic approaches that aim to improve quality of life and manage symptoms.

Surgery, on the other hand, is a primary treatment modality used to directly remove tumors or address medical conditions, rather than a complementary practice. It typically follows standard medical protocols rather than being an adjunct or alternative treatment. Complementary treatments like nutrition, acupuncture, and yoga focus on supporting the patient rather than providing direct intervention for the disease itself. This distinction underscores why surgery is categorized separately from other complementary options.
