Is buying a home near a nuclear plant a bad idea?

I am searching for my first house, and I have fallen in love with a beautiful town house on the lake. The only issue is the close proximity to the nuclear generating station. It is about 6 km away. I am concerned about the cancer risk as I have had cancer previously (Is the risk as bad as I’m thinking?) Also I am concerned about the land value and reselling the house in the future. Dumb idea?
