What characterizes a malignant tumor?

A malignant tumor is characterized by its ability to invade and destroy nearby tissues, as well as its potential to spread to other parts of the body through a process known as metastasis. This invasive nature distinguishes malignant tumors from benign tumors, which typically do not invade surrounding tissues or spread.

Malignant tumors can grow rapidly and are often associated with significant cellular abnormalities and uncontrolled cell division. This aggressive behavior contributes to their potential to disrupt the function of organs and systems in the body, making them a serious health concern. In contrast, benign tumors are usually well-defined, encapsulated, and generally do not pose a threat to life or health.

Understanding these characteristics is crucial in the medical field, as they influence treatment options and prognostic outcomes for patients diagnosed with cancer.
