Friend going through diagnosis

Hi 

My amazing and awesome friend is going through diagnosis and has a second biopsy today. She thought it was calcification but she has been told it is encapsulated breast cancer. 
 

The biopsy today is because they told her that her breast is like a snowstorm. 
 

Does anyone know what this means and I just want to know how best to support her really. I am taking her to the appointment as she is stubborn and stroppy and would go alone. She has other major health conditions which makes everything more tricky. She is stubborn about this too. Her friends are her family as they live abroad and she has a fabulous gang of 3 super close friends. 
 

Thanks
