Welcome to the Immunotherapy forum!

Immunotherapy medicines use the power of your body's immune system to attack cancer cells.

Your immune system is the network of organs, tissues, and cells that work together to protect your body from attacks by foreign invaders such as bacteria, parasites, viruses, and fungi that can cause infection and disease. When these invaders find their way into your body -- whether through a break in the skin, for example, or through your mouth or nose -- your immune system's response is the self-defense system that works to keep you from getting sick.

Immunotherapy medicines work by helping your immune system work harder or smarter to attack cancer cells. In cancer treatment, immunotherapy uses substances made by your body or in a lab to improve the function of the immune system by allowing the immune system to:

• stop or slow the growth of cancer cells
• stop cancer from spreading to other parts of the body
• be better at destroying cancer cells
