Mechanisms of Metastasis

Metastasis, the spread of cancer cells to distant organs, is the leading cause of cancer-related deaths. This complex process involves a series of steps, including invasion, intravasation into the bloodstream, survival in circulation, extravasation into new tissues, and colonization. The ability of cancer cells to metastasize is influenced by various molecular and environmental factors, including mutations, signaling pathways, and interactions with the tumor microenvironment. Understanding the mechanisms behind metastasis has become a critical focus in cancer research. By identifying key molecules involved in each step of metastasis, researchers hope to develop therapies that can block or reverse metastasis, providing new opportunities for preventing the spread of cancer and improving patient survival.
