DCIS question: Does a core needle biopsy break the duct and cause the cancer to spread?

DCIS is precancerous cells,so not invasive. . It is considered stage 0 and there is some talk about even if it should be called cancer. 

Ask what type of biopsy you had. 

I had the same question, can you spread from a biopsy? It was explained to me that the needle is like a vaccuum and when they click it it takes a small amount of flesh and sucks it up then released onto the slide for pathology. 

The breast may be a little inflamed from the trauma of it but it’s not usually the case that it would spread.
