I am so sorry to hear this...hubby just beat an aggressive form of prostate cancer, there is alot of good doctors and meds out there! Prayers for you and your family!
Gentle hugs, and all the best to you in this journey you're on. I echo other comments about excellent treatment options now. I have friends who are breast cancer survivors (and "thrivers"!) and continue to be in great health.
So sorry to hear your news. I am through with treatment, but dealing with side effects still. The breast cancer group on Reddit really helped me through some dark times.
I am sorry to hear this scary news. I wish you all the best, and sending good vibes your way. Ask if your hospital system has a breast cancer “buddy system” where a cancer survivor is paired with a women currently in treatment, as a sounding board, to answer questions, to offer hope and proof that you can and will get to the other side of this successfully.
