Definitions for "Atypical hyperplasia"
Means that there is increased cell production and the cells are slightly abnormal (although they are not cancer cells). This is usually diagnosed when a breast lump is tested to see if it is cancerous. Atypical hyperplasia is the only form of benign breast disease that is a risk factor for the future development of breast cancer. So if you are diagnosed with atypical hyperplasia, you will probably have the abnormal area removed and may be invited for breast screening more often.
