Can the same immune system that helps you fight off colds
help you stave off cancer?
This is the intriguing new questions scientists are now trying
to answer.
New drug therapies have been developed that use the
body's own immune system to fight cancer. Called
immunotherapies, the strategies use the body's natural
defense system to identify cancer cells as foreign invaders
and to kill them.
According to the National Institutes of Health, the immune
system is a complex network of cells and organs that work
together to defend the body against attacks by “foreign” or
“non-self” invaders.
This network is one of the body’s main defenses against
infection and disease. It's like an ID system.
The immune system works against diseases, including
cancer, in a variety of ways. For example, the immune
system may recognize the difference between healthy cells
and cancer cells in the body and works to eliminate
cancerous cells.
However, the immune system does not always recognize
cancer cells as “foreign.” Also, cancer may develop when the
immune system breaks down or does not function
adequately. Biological therapies are designed to repair,
stimulate, or enhance the immune system’s responses.
