Study links cell death pathway to cancer resistance and growth

A new study has uncovered an unexpected way cancer cells can escape the immune system, making it harder for treatments to work. The study, published in Cancer Cell, explains how a type of cancer cell death can actually make tumors grow faster by turning off the immune system's ability to fight the cancer.
