What are 3 abnormal tissues?

Here are three examples of abnormal tissues:

1. Hyperplasia

Hyperplasia is the abnormal growth and increase in the number of cells in a tissue. This can occur in response to various factors, such as chronic irritation or hormonal imbalances. Common examples of hyperplasia include:

- Endometrial hyperplasia: Thickening of the uterine lining in women, which can be caused by hormonal imbalances, obesity, or certain medications.

- Prostatic hyperplasia: Enlargement of the prostate gland in men, often associated with aging and hormonal changes.

2. Dysplasia

Dysplasia is a more severe form of abnormal tissue growth. It involves changes in cell size, shape, and organization, but does not represent a fully malignant (cancerous) transformation. Dysplasia can be caused by various factors, such as chronic inflammation or persistent viral infections. Common examples of dysplasia include:

- Cervical dysplasia: Abnormal changes in the cells of the cervix, which may be caused by HPV infection and are considered precancerous lesions.

- Bronchial dysplasia: Abnormal growth and changes in the cells lining the bronchial tubes, which can occur in response to chronic smoking or other lung diseases.

3. Neoplasia

Neoplasia is a general term used to refer to any new, abnormal growth of tissue. This category encompasses both benign and malignant tumors. Benign neoplasms, also known as benign tumors, are non-cancerous growths that do not spread to other parts of the body. Examples include uterine fibroids or skin moles. In contrast, malignant neoplasms, also known as malignant tumors or cancer, are characterized by uncontrolled cell growth, invasion of surrounding tissues, and the ability to spread (metastasize) to other parts of the body.
