Neoplastic

Neoplastic refers to the process that results in the formation of a neoplasm, a type of abnormal and excessive growth of tissue. The growth of a neoplasm is not coordinated with that of the normal surrounding tissue, and it persists growing abnormally, even if the original trigger is removed. This abnormal growth usually (but not always) forms a mass.

Types of Neoplasms

Neoplasms may be benign, pre-malignant (pre-cancerous) or malignant (cancerous).

• Benign neoplasms include adenoma, lipoma, and myoma. They are characterized by slow growth, well-defined borders, and the inability to spread to other tissues.
• Pre-malignant neoplasms include actinic keratosis and dysplasia. They have the potential to become malignant.
• Malignant neoplasms include carcinoma, sarcoma, and leukemia. They are characterized by fast, uncontrolled growth, ability to invade neighboring tissues, and spread to other parts of the body.

Causes

The exact cause of neoplasms is not well understood, but it is believed to involve a series of mutations in the DNA of a cell. Factors that may increase the risk of neoplasms include genetic disorders, exposure to certain chemicals and substances, certain infections, and poor lifestyle habits such as smoking and lack of exercise.

Diagnosis

Diagnosis of a neoplasm often involves imaging tests such as MRI, CT scan, and ultrasound. A biopsy may also be performed to examine the cells of the neoplasm under a microscope.

Treatment

Treatment of neoplasms depends on the type, location, and stage of the neoplasm, as well as the patient's overall health. Treatment options may include surgery, radiation therapy, chemotherapy, immunotherapy, targeted therapy, hormone therapy, stem cell transplant, or a combination of these.
