👉 The term "postillator" is used in medicine to refer to a type of cancerous growth that forms within a bone or other organ. It is characterized by the presence of abnormal cells that grow out of control and invade surrounding tissues, often leading to pain and swelling. Postillations are usually small, non-metastatic tumors that can be treated with surgery or radiation therapy. Postillations are also known as "bone metastases" in some medical contexts.
