Newly DX

Just found out on Jan 9th,2019 from my breast surgeon i have DCIS in my right breast. unclear the exact stage just yet, i have an appt with an oncologist thur and i'm kinda freaked out. I have a strong hx of cancer in my family. My mother has breast cancer twice in her right breast i her 40's and just last year in her late 60's which resulted in a double mastectomy. she has had 3 brothers die from cancer, 2 from lung and one from bone cancer and her sister also had breast cancer resulting in a single mastectomy. Cancer is also on my father's side of the family, so you can see why i am a little freaked. My excisional biopsy report shows a grade 3 dcis size 8.7cm, my margins were positive, so i'm assuming i will need more sx and have my lymph nodes tested. in initially had a needle core biopsy done which surprisingly came back negative, after i had a diagnostic mammogram and ultrasound that all pointed to cancer. i insisted the mass be removed and thank GOD i did. Sorry for the long post, i just need an outlet.
