Verified step by step guidance

Understand the basic definitions: A tumor is an abnormal growth of cells. Tumors can be classified as benign or malignant based on their behavior and characteristics.

Identify the characteristics of benign tumors: Benign tumors are non-cancerous growths that do not invade nearby tissues or spread to other parts of the body. They are usually encapsulated and grow slowly.

Identify the characteristics of malignant tumors: Malignant tumors are cancerous and have the ability to invade nearby tissues and spread to distant organs through a process called metastasis. They tend to grow more rapidly and are not encapsulated.

Compare the invasive nature: The primary difference is that benign tumors do not invade nearby tissues, whereas malignant tumors do. This invasive nature is a key factor in determining the potential harm of the tumor.

Clarify misconceptions: Benign tumors can vary in size and are not always smaller than malignant tumors. Malignant tumors can cause pain, but this is not a definitive characteristic as both types can be painless or painful depending on their location and size.
