Cancer vaccines are intended either to treat existing cancer or to prevent the development of cancer.
Cancer treatment vaccines are designed to strengthen the body's natural defenses against a cancer that has already developed.

There are several types of treatment vaccines under study, based on a number of different strategies.
Every type, however, works under the premise of using the body’s immune system to fight the cancer, which might entail making the cancer appear foreign – and more visible – to the immune system while at the same time, boosting the system’s response.
Researchers hope that when a vaccine containing cancer-specific antigens is injected into a patient, these antigens will stimulate the immune system to attack cancer cells without harming normal cells.
More than 15 vaccines currently are in trials for a range of diseases, including lymphoma, melanoma, breast, lung, prostate and colorectal cancers, with mostly mixed results to date.
Some of the more widely publicized vaccines include:
In 2005, an uncontrolled trial of Provenge, an experimental cancer vaccine made by Seattle-based Dendreon, showed that men with advanced prostate cancer lived longer, though it did little to stop disease progression.
