**Core Concept**
Angiofibroma, also known as juvenile nasopharyngeal angiofibroma (JNA), is a highly vascular benign tumor that primarily affects adolescent males. It arises from the nasopharynx and can cause significant morbidity due to its potential for extensive local invasion and bleeding.

**Why the Correct Answer is Right**
The treatment of choice for angiofibroma is surgical excision, often performed by an otolaryngologist or head and neck surgeon. The goal is to remove the tumor in its entirety while preserving surrounding structures. Preoperative embolization may be used to reduce blood flow to the tumor, making it easier to manage intraoperatively. This approach allows for the best possible outcomes in terms of tumor control and minimizing the risk of recurrence.

**Why Each Wrong Option is Incorrect**
**Option A:** Radiation therapy is not the primary treatment for angiofibroma due to its benign nature and the potential for long-term radiation-induced complications.
**Option B:** Chemotherapy is not typically used to treat angiofibroma, as it is not an effective strategy for managing this type of tumor.
**Option C:** Embolization alone may be used as an adjunct to surgery, but it is not a standalone treatment for angiofibroma.

**Clinical Pearl / High-Yield Fact**
It's essential to recognize that angiofibroma is a highly vascular tumor, and preoperative embolization can significantly reduce the risk of intraoperative bleeding. However, surgical expertise and experience are crucial in managing these cases effectively.

**Correct Answer: C. Embolization may be used as an adjunct to surgery to reduce blood flow to the tumor.**
