A malignant tumor is considered more dangerous than a benign tumor primarily because its cells can invade other tissues. This characteristic sets malignant tumors apart, as they have the ability to spread beyond the original site of the tumor into surrounding normal tissues and can metastasize to distant body parts via the bloodstream or lymphatic system.

This invasive nature contributes to the severity of malignant tumors, as they can disrupt the function of vital organs and systems. The ability to invade and metastasize poses a greater threat to the overall health and survival of the individual, as opposed to benign tumors, which typically do not invade surrounding tissues and are generally considered less aggressive.
