Neoplasms

Neoplasms (pronounced: nee-oh-plaz-uhmz), also known as tumors, are abnormal growths of tissue that can be benign (non-cancerous) or malignant (cancerous). The term "neoplasm" is derived from the Greek words "neo" meaning new, and "plasma" meaning formation or creation.

Etymology

The term "neoplasm" was first used in the early 19th century and is derived from the Greek words "νέος" (neos), meaning "new", and "πλάσμα" (plasma), meaning "formation" or "creation". It is used in medical terminology to describe any new and abnormal growth of tissue in the body.

Types of Neoplasms

Neoplasms can be classified into two main types: benign and malignant.

  • Benign neoplasms are non-cancerous growths that do not spread to other parts of the body. They grow slowly and are usually encapsulated, meaning they are confined to a specific area. Examples include adenomas, lipomas, and fibromas.

Diagnosis and Treatment

Diagnosis of neoplasms often involves imaging tests such as Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans, and may also involve a biopsy to examine the tissue under a microscope. Treatment options depend on the type and stage of the neoplasm, and can include surgery, chemotherapy, radiation therapy, or a combination of these.
