My Daughter Is 46 Years Old. She Has Been Treated

My daughter is 46 years old. She has been treated for basil cell skin cancer. She has a freckled completion. She has a pool in the back yard, and seems to want to get in it a lot. She also likes to mow grass, but says that she wears a large straw hat. I am concerned about her or I wouldn't be writing this to you. What can I say to her to make her take it more seriously?
