Which of the following is a common treatment for cancerous tumors?

The treatment of cancerous tumors often involves a combination of several approaches, which is why the inclusion of surgery, radiation therapy, and chemotherapy in the correct answer is significant.

Surgery is a primary method used to physically remove tumors from the body, especially if they are localized and accessible. This approach can help eliminate cancerous cells and is often the first line of treatment.

Radiation therapy uses high-energy waves to target and destroy cancer cells, particularly effective for tumors that are difficult to access surgically or to shrink tumors before surgery.

Chemotherapy involves the use of drugs to kill cancer cells or slow their growth, which can be crucial in treating tumors that have spread beyond their original site or in cases where the cancer cannot be surgically removed entirely.

The combination of these methods addresses the complexity of cancer treatment, aiming not only at removing the tumor but also at managing and reducing cancer cell proliferation. Other options, such as physical therapy, acupuncture, and exercise programs, may play supportive roles in a cancer patient's overall well-being and recovery, but they do not directly target the tumor itself as a treatment modality.
