Scared I have inflammatory breast cancer

Hi I have a painful and swollen breast. There appears to be some hardening under the skin. I went to the doctors and they have referred me to the breast clinic. I have woken up this morning with some orange peel effect on my breast which I know is another symptom of inflammatory breast cancer. I am just so terrified. I have a 4 year old and nine month old and I am so terrified of them growing up without me.
