Recently diagnosed

hi I'm 29 and I've recently been diagnosed with grade 2 invasive  ductal  carcinoma. 

Absolutely devastated by the results but I think I knew in a way it wasn't going to be a good outcome. I'm waiting for a MRI and another ultrasound scan  before they make a decission on what treatment to go with. I just feel like it's all taking ages as I found the lump on mothers day (of all days) and my breast is having spurts of pain throughout the days.
