Definition: Hyperplasia occurs when cells within an organ or tissue grow larger and faster than expected. Hyperplastic breast tumors are benign (not cancerous).
Also Known As: hypergenesis
Common Misspellings: hiperplasia, hyperplaysia
Examples: Atypical ductal hyperplasia occurs in the cells that line the breast ducts, and is associated with an increased risk of developing breast cancer. If usual ductal hyperplasia is found in your breast biopsy, it does not raise your risk of breast cancer.
