New Pyk2-derived peptide inhibits breast cancer metastasis

An estimated ninety percent of deaths from breast cancer are due to complications resulting from metastasis, a process in which cancer cells break away from where they first formed, travel through the blood or lymph circulatory system, and form new, metastatic tumors in other parts of the body.
