A mechanism that causes cancer cells to metastasize has been described as a “chase and run” between healthy cells and cancer cells. As healthy cells try to evade the cancer cells, they emit a chemical attractant that causes the malignant cells to follow them, thus spreading the cancer. The researchers hope this information can be used in the future to find a new way to treat metastasis.
