Breast appointment with biopsy

Hi

I went to my apt at the hospital  on a 2 week wait I’ve had a right day today.  Went in mainly due to eczema on my right breast, which at first the consultant said it probably is eczema and she was gonna ask my Gp to refer me to a dermatologist and ask them to check my urine. Anyway had a mammogram, then ultrasound. Radiologist picked up dense tissue with lots of cysts on my left breast. Had another mammogram and a biopsy. Saw consultant and have to go back on 27th June. Even if it is not the cancer I was told I will to have to the abnormal tissue  taken out of my breast. 

I am not petrified that it could be cancer but no matter what I will have to have another procedure. Has anyone else had the same problem with dense tissue in their breast
