I was in a head-on collision in 1986, and subsequently, my chest turned black and I thought then that I would someday have breast cancer. But when I was told, I felt very guilty and felt I had caused it. And I was honest with the nurse and she told me that trauma does not cause cancer. I later thought that because I didn't have regular check-ups after I'd been sent to a surgeon regarding my right breast, once again I was at fault. But then it turned out to be my left breast that was in question this time. So it was a real relief for me.
