Vinorelbine

How vinorelbine works

Vinorelbine works by blocking cancer cell growth by stopping mitosis, the process of cells dividing. It stops the forming of microtubules, the structures of the cell that help move the information inside them during cell division. Vinorelbine stops the cancer cells from dividing into new cells.
