Verified step by step guidance

Understand the difference between benign and malignant tumors. Benign tumors are non-cancerous growths, while malignant tumors are cancerous and can spread.

Recognize that benign tumors do not invade surrounding tissues, which is a key characteristic that differentiates them from malignant tumors.

Malignant tumors have the ability to metastasize, meaning they can spread to distant organs, whereas benign tumors do not have this capability.

Benign tumors are typically composed of differentiated cells, meaning the cells resemble normal cells, unlike malignant tumors which may be composed of undifferentiated cells.

Consider the impact on health: benign tumors are not always life-threatening, whereas malignant tumors can be due to their aggressive nature and potential to spread.
