The main difference between a malignant tumor and a benign tumor lies in their ability to spread or metastasize.

1. Benign Tumors: These are typically not harmful unless they are pressing on vital organs or are in a location where they interfere with the body's normal function. They do not spread to other parts of the body (metastasize), and they usually stay localized in one place. They can often be removed and, in most cases, they do not come back.

2. Malignant Tumors: These are more serious and potentially life-threatening. Malignant tumors can invade and damage nearby tissues and organs. They also have the ability to spread throughout the body, which is called metastasizing. This spreading process happens when cancer cells get into the body’s bloodstream or lymph vessels. From there, they can travel to distant parts of the body and form new tumors, making them much harder to control.

So, to answer your question:

• Benign tumors do not spread (or metastasize).
• Malignant tumors can spread (or metastasize).
• It's not accurate to say that only benign tumors are fatal. In fact, benign tumors are usually not life-threatening unless they are in a critical location in the body.
• Malignant tumors can be fatal if not treated promptly and effectively, due to their ability to spread and damage vital organs.
