Multicentric breast cancer

Last revised by Vikas Shah on 27 Jul 2022

A multicentric breast cancer is a term given to a breast cancer where there are two or more breast cancers separated by normal breast tissue (often taken as 5 cm of separation 4). It is related to but distinct from the term multifocal breast cancer.

At a pathological level It can also mean 2

  • tumor with minimum one satellite node in the same or another quadrant of the breast
  • minimum one cut through the breast without tumor cells
  • histopathologically, discontinued tumors with intra-ductal invasion.

Some authors also use the term multicentric breast cancer when there are tumor foci involving more than one quadrant.
