## 해설

A neoplasm is an abnormal mass of tissue that results from abnormal cell division. It can be benign (non-cancerous) or malignant (cancerous). Unlike normal cells, neoplastic cells continue to grow and divide in an uncontrolled manner. Malignant neoplasms can invade surrounding tissues and spread to other parts of the body through metastasis.

## 임상 시나리오

1. Neoplasm Types:
- Benign: localized, slow-growing, well-circumscribed
- Malignant: invasive, metastatic potential, rapid growth

2. Characteristics of Neoplasms:
- Uncontrolled cell proliferation
- Abnormal cell differentiation
- Loss of normal growth regulation
- Ability to evade apoptosis

3. Common Neoplasm Sites:
- Breast tissue
- Lung tissue
- Colon
- Skin
- Brain tissue

4. Diagnostic Methods:
- Biopsy
- Imaging studies
- Tumor markers
- Histological examination

5. Risk Factors:
- Genetic predisposition
- Environmental exposure
- Age
- Lifestyle factors
- Chronic inflammation

6. Treatment Approaches:
- Surgery
- Chemotherapy
- Radiation therapy
- Immunotherapy
- Targeted therapy

## 핵심 개념

- **neoplasm** — An abnormal growth of tissue resulting from excessive cell division, which can be either benign or malignant. Malignant neoplasms can invade nearby tissues and spread to other body parts.
- **abscess** — A localized collection of pus surrounded by inflamed tissue, typically caused by bacterial infection. It can occur in any part of the body and is characterized by swelling, redness, and pain.
- **cyst** — A closed sac-like structure containing fluid, air, or semi-solid material that develops abnormally in body tissue or an organ. It typically has a distinct membrane and can occur anywhere in the body.
- **granuloma** — A small area of inflammation in tissue characterized by the accumulation of immune cells, particularly macrophages, forming a compact, ball-like cluster in response to infection or foreign substances.
- **hematoma** — A localized collection of blood outside blood vessels, usually caused by injury or trauma. It occurs when blood vessels are damaged and blood leaks into surrounding tissues, causing swelling and discoloration.
