👉 Vinblastine is a medication used to treat certain types of cancer. It works by inhibiting the function of a protein called BCR-ABL in blood cancers, which helps stop the growth and spread of those tumors. This can help slow or even stop the progression of cancer. Vinblastine has been shown to be effective against some types of cancer, but it's important to note that its effectiveness may vary depending on the type of cancer and the individual patient's response to treatment.
