Which treatment improves patient immunity to help fight cancer cells?

The correct answer is that interferons improve patient immunity to help fight cancer cells. Interferons are a type of protein that the body naturally produces in response to infections and tumors. They play a crucial role in the immune response by enhancing the activity of immune cells, such as T cells and natural killer cells, which are essential in recognizing and destroying cancer cells.

Interferons can also have antiviral effects and can help inhibit tumor growth by increasing the ability of immune cells to target cancer effectively. Their use in cancer treatment is often referred to as immunotherapy, which is a treatment approach that utilizes the body's immune system to fight cancer.

While chemotherapy and radiation therapy primarily work by directly attacking cancer cells to reduce tumor size or eliminate them, they do not specifically enhance the immune response. Surgery is a method of physically removing tumors, but it does not inherently boost immunity in the same way that interferons do. Therefore, interferons stand out as the treatment specifically aimed at enhancing the patient’s immune system to combat cancer cells.
