Hormone therapy uses drugs to stop the body from producing testosterone. Less commonly, it may 
include surgical removal of the testicles. Without testosterone, prostate cancer cells may die or 
grow more slowly

Radiation therapy uses high-powered energy to kill cancer cells.

Immunotherapy uses the body’s natural defenses (the immune system) to find, attack, and kill 
cancer cells. Some kinds of immunotherapy use your own immune cells, while others use 
medicines that are made in a lab. 

Targeted therapy aims to more precisely attack cancer cells. These drugs target changes in the 
genes or proteins of cancer cells that help them grow, divide, and spread. 

Chemotherapy uses drugs to kill cancer cells. It is most commonly used when prostate cancer has 
spread to other parts of the body or doesn’t respond to hormone therapy alone. Chemotherapy for 
prostate cancer is usually given through a vein, and treatment can take several months.
