II: Neoplasms

Neoplasms, also known as tumors, are abnormal growths of tissue that can occur in any part of the body. They can be benign (non-cancerous), pre-malignant (pre-cancerous), or malignant (cancerous). Whether a neoplasm is benign or malignant depends on how it grows and spreads. Typically, benign neoplasms grow slowly and don't spread to other parts of the body, while malignant neoplasms grow quickly and can invade and damage nearby tissues and organs. Common symptoms of neoplasms range widely depending on the location and size of the growth but may include pain, swelling, or unexplained weight loss. The causes of neoplasms are diverse and can include factors such as genetic abnormalities, exposure to certain chemicals or radiation, certain infections, or a weak immune system. These conditions can affect the body's normal functioning and may progress over time, potentially leading to serious health complications.
