Hyperplasia, metaplasia, and dysplasia are reversible because they are results of a stimulus. Neoplasia is irreversible because it is autonomous.

What is the difference between hyperplasia and dysplasia?
In hyperplasia, there is an increase in the number of cells in an organ or tissue that appear normal under a microscope. In dysplasia, the cells look abnormal under a microscope but are not cancer. Hyperplasia and dysplasia may or may not become cancer.
Does hyperplasia lead to neoplasia?
In some instances, pathological hyperplasia may progress to neoplasia. For example, hepatocellular adenoma or carcinoma is closely related to compensatory hyperplasia of hepatic parenchymal cells seen in cirrhotic livers of chronic alcoholics.
What is the difference between neoplasia and dysplasia?
The tissue becomes disordered in appearance, often with an increase in the numbers of immature cells, and greater variability between cells. This appearance is called dysplasia. ... Neoplasia is the term used to describe the development of tumours or cancerous tissue.
What is the difference between neoplasm and neoplasia?
Neoplasia (nee-oh-PLAY-zhuh) is the uncontrolled, abnormal growth of cells or tissues in the body, and the abnormal growth itself is called a neoplasm (nee-oh-PLAZ-m) or tumor. It can be benign (bee-NINE) or malignant.
Can hyperplasia be reversed?
Results. Based on four large series, more than 90% of endometrial hyperplasia caused by ERT can be reversed by medical treatment.
What does hyperplasia look like?
Hyperplasia is often described as either usual or atypical based on how the cells look under a microscope. In usual hyperplasia, the cells look very close to normal. In atypical hyperplasia (or hyperplasia with atypia), the cells are more distorted.
What is an example of neoplasia?
Examples: Adenoma (benign neoplasm of glandular epithelium), fibroadenoma (benign neoplasm of the breast), and leiomyoma (benign neoplasm of smooth muscle).
What is an example of hyperplasia?
Hyperplasia. Basic description: Increase in the number of cells. Physiologic hyperplasia: Occurs due to a normal stressor. For example, increase in the size of the breasts during pregnancy, increase in thickness of endometrium during menstrual cycle, and liver growth after partial resection.
What causes hyperplasia?
Endometrial hyperplasia most often is caused by excess estrogen without progesterone. If ovulation does not occur, progesterone is not made, and the lining is not shed. The endometrium may continue to grow in response to estrogen. The cells that make up the lining may crowd together and may become abnormal.
What are the two types of neoplasms?
There are two general types of tumors: benign (non-cancerous) tumors and malignant (cancerous) tumors. A benign tumor is composed of cells that will not invade other unrelated tissues or organs of the body, although it may continue to grow in size abnormally.
What causes neoplasia?
Causes of neoplastic disease
In general, cancerous tumor growth is triggered by DNA mutations within your cells. Your DNA contains genes that tell cells how to operate, grow, and divide. When the DNA changes within your cells, they don't function properly. This disconnection is what causes cells to become cancerous.
What are the types of neoplasms?
ICD-10 classifies neoplasms into four main groups: benign neoplasms, in situ neoplasms, malignant neoplasms, and neoplasms of uncertain or unknown behavior. Malignant neoplasms are also simply known as cancers and are the focus of oncology.
