Mostly fibroadenoma lump till 2009. first child birth in 2011 could not locate the fibroadenoma till 2014. found lump same location. could it be same?

Could be: It could be the same lump or one adjacent to the last one.

The same: If a solitary lesion felt to be fibroadenoma noted in 2009 and same lesion now located in 2014 it would be rare to have malignant transformation and not notice larger, firmer lesion causing skin retraction. Sono can help define. Many fibroadenomas regress or remain same. It is the effect of hormones on breast parenchyma in younger females which later reverts to an effect on duct system.
