"Hello I'm Dr. David Cathcart, I'm a family practice physician from Heartland Regional Medical Center in St. Joseph. And we're going to talk about chemotherapy drugs and their side effects today. Chemotherapy drugs are medications that are used to interrupt the rapid growth of cancerous cells. Now there is a whole wide variety of these medications that are on the market. And some of them have more side effects than others. But in general, these drugs work on rapidly dividing cells, so that any cell that's growing or in it's state of division as it grows and multiplies, can be effected by the chemotherapy drug. These chemotherapy drugs tend to interrupt the cells growth or replication in various stages of the cell growth cycle. So that any cell that is growing can be effected by the chemotherapy drug. So for example, if you have a cancer cell that is growing rapidly, and you have other cells that are also growing. For example, hair cells, the cancer chemotherapy drug does not really care if it is dealing with a cancer cell or if it is dealing with a hair cell. So either way, it will kill those cells that are dividing. And in most cases it doesn't touch the cells that are not dividing. The good news is for us is that for cancer cells that are rapidly dividing, most of our other cells in our body like our skin, and our eyes, and our big toe is not rapidly dividing, so those are not effected too much. So that's how the cancer chemotherapy drugs are, and that's essentially how they do their job. This is Dr. Cathcart talking about what are cancer chemotherapy drugs."
