Hello Bathsehba-1960 and thanks for posting,

I am sorry to learn that about your diagnosis and can understand it was a shock. I hope you are doing ok after your operation. 

Calcifications can develop anywhere in the breast tissue and sometimes they occur in blood vessels (arteries).  This type of calcification is fairly common and can increase with age. Some research studies noticed that calcification in the arteries was seen more often in people with diabetes - I think this is what the leaflet is referring to, so it is the case.

If you want to have a chat with one of the nurses, do give us a call on Freephone 0808 800 4040 , we are here weekdays 9-5.

Best wishes,

Julia
