I totally agree with that!
However, I disagree with your decision to do nothing if you get breast cancer. Once again, breast cancer is highly curable (I know, I had it). In fact, I have a friend who, four years ago, was diagnosed with stage 4 breast cancer. She was told she had 6 months to live, and the doctor told her that, it was up to her, but he didn't think a mastectomy at that stage would prolong her life (it was already in her bones and her brain).
But, today she is still living with cancer. She saw her only daughter get married, and she now has a grand daughter. She is ill, but still feels well enough to get out a couple of times a week, to travel to see her grand daughter in Florida, and to play bridge twice a month.
I hope, if ever you are are faced with breast cancer, you will consider all your options.
