Dysplasia refers generally to abnormal changes in cellular shape, size, and/or organization. Dysplasia is not considered a true adaptation; rather, it is thought to be related to hyperplasia and is sometimes called "atypical hyperplasia." Tissues prone to dysplasia include cervical and respiratory epithelia. Dysplasia often occurs in the vicinity of cancerous cells, and it may be involved in the development of breast cancer.
