Which of the following is NOT a common approach for treating cancer?

Acupuncture

The answer is Acupuncture. Acupuncture is a traditional Chinese medicine treatment that is not considered a standard treatment for cancer. Surgery, radiation therapy, and immunotherapy are all well-established and effective treatments for cancer. Acupuncture is not a standard treatment for cancer because there is not enough scientific evidence to support its effectiveness. However, some people do use acupuncture as a complementary or alternative treatment for cancer.

Here is a brief explanation of each of the four options:

• Surgery is the removal of the tumor and some of the surrounding tissue. It is a common treatment for many types of cancer.
• Radiation therapy uses high-energy beams to kill cancer cells. It is a common treatment for many types of cancer.
• Immunotherapy uses the body's own immune system to fight cancer. It is a newer treatment for cancer, but it is becoming increasingly common.
• Acupuncture is a traditional Chinese medicine treatment that involves inserting needles into specific points on the body. It is not a standard treatment for cancer, but some people do use it as a complementary or alternative treatment.
