Angelina Jolie’s situation isn’t relevant to these results or to treatment plans for breast cancer. She didn’t have breast cancer.
That’s the whole point. Her actions were driven by irrational fear due to the cancer her mother suffered from; although Marcheline Bertrand did have breast cancer, she died from the ovarian cancer.
True, she’s really only relevant as a symbol of a woman placing a high value on her life, and a low value on her sex appeal to pubescent males.
