Precision medicine is like getting a custom-made treatment plan just for you. It looks at your genes, lifestyle, and environment to figure out the best way to treat you. For example, if you have cancer, precision medicine can give you medicine that's specifically designed for your body, based on your genes. This makes the treatment more effective because it targets the cancer cells in a way that works best for you.

Precision medicine is a big deal in healthcare because it can change how we treat diseases. Right now, it's mostly used for cancer, but it can also help with other diseases like rare conditions or infections. However, there are still challenges to overcome before precision medicine can be used everywhere. Things like making sure everyone has access to it, and teaching doctors how to use it, are some of the hurdles we need to clear before precision medicine can be used by everyone.
