I am a man and never thought I would have breast cancer. I did it alone before deciding on provider and surgery. The only thing I can share with you is a cancer podcast interview where I was asked how did I do it, processing, managing emotions and cultural bias. Even now I struggle with side effects of daily meds and listen to the podcast for inspiration. Lol
