How are Biological Therapies Different?

What is Biological Therapy?

Biological therapy is a cancer treatment that uses the body to fight against the cancer by stimulating the immune system to recognize and fight the cancer cells. Some biological therapies do not target cancer cells directly but stimulate other chemicals or cells to attack the cancer. These types of biological therapy are sometimes referred to collectively as “immunotherapy” or “biological response modifier therapy.”

Other biological therapies, such as antibodies or segments of genetic material, target cancer cells directly. Biological therapies that interfere with specific molecules involved in tumor growth and progression are also referred to as targeted therapies.

Biological therapies may be used to treat cancer or the side effects of other cancer treatments.

What is the difference between chemotherapy and biological therapies?

Chemotherapy uses drugs, while biological therapy (or immunotherapy) uses what we naturally produce in our bodies.

Since cancer cells divide and grow rapidly, chemotherapy is made to target rapidly dividing cells and kill them. Biological therapy treatments do not directly kill cancer cells. Instead, they help your immune system fight the cancer.
