How can I get husband to check for cancer?

After my friend's father died from testicular cancer, I got a little nervous and asked my husband if he did self exams. He said no, that he isn't worried about it because the Lord will take him when its time. To make me feel better he told me the Army does examinations for it, (but only once every two years) How can I talk to him about this and get him to take precautions???
