Today is Melanoma Monday -- a day set aside each year to help raise awareness about melanoma, which is considered the deadliest form of skin cancer. We spoke with a young woman about how she found out she had melanoma and why it's important to get checked if you notice anything unusual. When it comes to prevention, Doctor Gastman says it's important to regularly apply sun screen and avoid getting sun burned. UV protective clothing can also be helpful if you're going to be outside for a long period of time.
