Neoplastic Disorders: Introduction to Neoplasia

Neoplasia refers to abnormal and excessive tissue growth, often resulting in tumor formation. These growths can be benign or malignant, impacting various organs and systems.

Definition and Classification

Neoplastic disorders originate from genetic mutations leading to unregulated cellular proliferation. These disorders are classified into:

• Benign Neoplasms - Non-invasive growths with a slow progression.
• Malignant Neoplasms - Aggressive tumors that invade surrounding tissues and may metastasize.

Causes and Risk Factors

Neoplasia can result from various factors, including:

• Genetic predisposition
• Carcinogenic exposure (e.g., tobacco, radiation)
• Chronic inflammation
• Viral infections

Diagnosis and Management

Diagnosis often involves imaging techniques, biopsy, and molecular markers to classify the tumor type. Management strategies include:

• Surgical removal
• Chemotherapy and targeted therapies
• Radiation therapy
• Immunotherapy
