Shall we talk about the cancer drug Pemigatinib? (Pemigatinib Tablets)

When you or a loved one is prescribed a new cancer medication, it's normal to feel a little apprehensive and curious. There are many questions that come to mind, such as what kind of medication it is, how it works, and what to be careful about. Today, we are going to talk about one such specific anti-cancer drug, Pemigatinib. After reading this article, you will have a better understanding of this medication.

What is Pemigatinib?

Simply put, Pemigatinib is a targeted therapy . That means it specifically targets and attacks cancer cells, rather than affecting every cell in the body like older cancer drugs.

This medicine mainly treats:

• For bile duct cancer .
• For some types of bone marrow-related cancers (Myeloid/Lymphoid Neoplasm) .

Think of cancer cells as weeds. These weeds need a special nutrient (protein) to grow. What the drug Pemigatinib does is stop that nutrient from getting to the cancer cells. It's like turning off the water pipe to the weeds. Then the cancer cells lose or greatly reduce their ability to grow and spread throughout the body. You'll see the brand name for this drug, Pemazyre .
