margin clear

Hi, I hope somebody can help me, can 2mm be a margin clear?

Dear Pink64,   In general, surgeons prefer a margin of normal tissue surrounding the area of concern of at least 1 millimeter or 0.1 cm.  Other information is also taken into account when determining the adequacy of the surgical margin such as types of cells found at the margin (DCIS vs. invasive cancer).  Your surgeon would be best able to discuss this issue with you.
