**Core Concept**
Small cell carcinoma (SCC) of the lung is a neuroendocrine tumor characterized by rapid growth and early metastasis. It is often associated with paraneoplastic syndromes due to its neuroendocrine properties.

**Why the Correct Answer is Right**
Small cell carcinoma of the lung typically exhibits features such as:
- **Paraneoplastic syndromes**: These are systemic complications of cancer, often related to the neuroendocrine activity of the tumor.
- **High propensity for metastasis**: SCC spreads rapidly, often to the brain, bones, liver, and adrenal glands.
- **Response to chemotherapy**: SCC is highly sensitive to chemotherapy, particularly platinum-based regimens.

**Clinical Pearl / High-Yield Fact**
Small cell carcinoma of the lung is often associated with **paraneoplastic syndromes**, such as Cushing's syndrome, SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion), and Eaton-Lambert syndrome. These syndromes can be the presenting feature of the disease.
