Complex: Many ways immune system is involved. Prevalent theory that "immune surveillance" is keeping cancers from developing in healthy people. That is one reason why cancers are more prevalent as we age. Also why certain cancers are found in high incidence in people with immune suppression (aids, organ transplant recipients, etc). Newer therapies also use some parts of the immune system to work.

Tumors excape immune: Tumors grow in the body if the immune system is not potent enough to destroy them. The hope is that immune stimulant therapies will be available to help the body in fighting these tumors with it's natural killing mechanisms.
