A tumor is a growing mass of abnormal cells. Describe the difference between a benign tumor and a malignant tumor.

Key Concepts

Benign Tumors

Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. They typically grow slowly and are often encapsulated, making them easier to remove surgically. While they can cause problems by pressing on nearby organs or structures, they generally do not pose a significant threat to life.

Malignant Tumors

Malignant tumors are cancerous and have the ability to invade surrounding tissues and metastasize, or spread, to distant sites in the body. They grow more aggressively than benign tumors and can disrupt normal bodily functions. The presence of malignant cells often requires more extensive treatment, such as chemotherapy or radiation, in addition to surgery.

Tumor Classification

Tumors are classified based on their behavior and characteristics, primarily into benign and malignant categories. This classification is crucial for determining the appropriate treatment and prognosis. Understanding the differences in growth patterns, potential for metastasis, and overall impact on health helps in making informed medical decisions.
