As @panarosmith said, "you've got this girl!"
I'm 21 years past a stage 0, DCIS diagnoses, both breasts, at age 54. It started with a suspicious mamo (only 11 months after the previous one), followed by ultrasound, then biopsy, and finally MRI guided biopsies, 1 in each breast. All 3 biopsies were positive. It was mind numbing for awhile. Then I just put one foot in front of the other and kept on going. A month later I had a bilateral mastectomy with immediate reconstruction. No radiation, no chemo. I never looked back. I feel the keys to my treatment and recovery were my surgeons and their staffs. The breast surgeon and plastic surgeon were in lock-step throughout; wonderful, skilled, supportive people.
Wishing you all the best as you begin your journey!
