An osteosarcoma (OS) or osteogenic sarcoma (OGS) is a cancerous tumor in a bone. Specifically, it is an aggressive malignant neoplasm that arises from primitive transformed cells of mesenchymal origin (and thus a sarcoma) and that exhibits osteoblastic differentiation and produces malignant osteoid.

The other day while sitting around and watching television my sister came to me asking me to watch this video she found on youtube. I then proceeding to agreeing to watch the video and found out about Zach Sobiech and his battle with Osteosarcoma. I never knew what Osteosarcoma was and quite frankly I never knew it even existed. As you can read above, Osteosarcoma is a cancer of the bones that is a very intense and aggressive cancer. I have always been interested in becoming a doctor and helping to save peoples lives so when I saw this video I was completely moved. Being a teenager like Zach, this video really changed my perspective on my life and I suggest everyone take out the 20 minutes from their day to watch this video. Hopefully, you will be just as moved as I was and start to live each and every precious day of life to the fullest.
