Study: New strategy shows promise in treating leukemia

A new strategy for genetically bolstering the immune system to fight against leukemia has proven effective in a small study that may have broader implications for fighting cancer.

The treatment, which uses a patients' own blood cells to destroy their cancer cells, eradicated blood cancer tumors in less than a month and led to sustained remissions of up to a year.

Today on American Morning, Elizabeth Cohen, senior medical correspondent, explains the findings and breaks down how the strategy could be used to treat cancer on a broader scale.
