Pseudoangiomatous stromal hyperplasia is the presence of excess breast support (stromal) tissue in an area that forms a lump or may involve large parts of the breast to make it firm and lumpy. These benign growths can increase in size quite quickly and may be mistaken for a fibroadenoma of breast cancer. They can be surgically removed if only a small area is involved.
