Dysplasia意思

"Dysplasia" is a term used in medicine to describe an abnormal growth or development of cells or tissues. It typically refers to a pre-cancerous condition where the cells show signs of abnormal changes, but have not yet become cancerous. Dysplasia can occur in various parts of the body, including the skin, mouth, esophagus, cervix, and colon.

There are different grades of dysplasia, which indicate the severity of the cellular changes:

• Low-grade dysplasia: Also known as mild dysplasia, this is the earliest and least severe form of dysplasia. The cells show minor abnormalities, and the risk of progressing to cancer is low.

• High-grade dysplasia: Also known as severe dysplasia, this is a more advanced form where the cells show more significant abnormalities. High-grade dysplasia is more likely to progress to cancer, and it usually requires more aggressive treatment.

Dysplasia is often detected through screening tests or biopsies and is typically treated to prevent progression to cancer. The treatment approach can vary depending on the location and grade of the dysplasia, and may include monitoring, removal of affected tissue, or in some cases, surgery.
