Malignant Tumor

Definition - What does Malignant Tumor mean?

A malignant tumor is a cancerous group of cells which grow out of control and can become life threatening. These cells can spread to other parts of the body from their original location and grow larger in different parts of the body by breaking off and spreading through the blood stream. This is the main difference between malignant and benign tumors.

Safeopedia explains Malignant Tumor

The word "malignant" is a descriptive term used to describe anything that threatens life or wellbeing and has a tendency to become increasingly worse or grow rapidly in ways that can cause death. The other tumors that have spread to other parts of the body and continued growth are called metastases. The area that the tumor grows dictates the name of the original growth and the metastases that stem from this region, even if they arrive elsewhere.
