Paraneoplastic Syndromes

Paraneoplastic syndromes are a group of rare disorders that occur when cancer causes unintended effects in the body, outside of the tumor itself. They happen because cancer cells sometimes produce or trigger immune responses against substances that affect organs like the nervous system, skin, or hormones. These syndromes can lead to symptoms such as weakness, hormonal imbalances, or neurological problems, often before the cancer is diagnosed. Recognizing paraneoplastic syndromes can help in early cancer detection and management. They highlight how cancer can impact the body in ways beyond the primary tumor.
