There is some promising new prostate cancer research.
Doctors developed a vaccine that eliminates prostate tumors in mice and it's giving them hope a human vaccine could come next.
The shot is made of healthy prostate D.N.A. tissue and teaches the immune system how to recognize and attack cancer cells.
Tumors in mice that received the vaccine went away without chemo, radiation or major side effects.
Doctors at the mayo clinic and in the U.K. developed the vaccine.
They hope to start human trials within two years.
