Are you or someone you care about living with cancer?

Cancer researcher Robert Weinberg discusses what he calls the last frontier of cancer research — discovering how and why cancers spread through the body. In two recent studies, Weinberg and his colleagues found clues to understanding tumor metastases.

Weinberg has been instrumental in studies of oncogenes — genes that can spark the rapid cell multiplication associated with cancerous tumors. Weinberg's most recent research found that microRNAs — small molecules that typically disrupt protein production — can cause tumors to metastasize.

Robert Weinberg, professor of cancer research at Massachusetts Institute of Technology; member of the Whitehead Institute for Biomedical Research
