A Malignant Tumor is More Dangerous Than a Benign Tumor

Question

A malignant tumor is more dangerous than a benign tumor because
A)its cells are proliferating faster.
B)it causes neighboring cells to mutate.
C)its cells attack and phagocytose neighboring normal tissue cells.
D)its cells invade other tissues.

Accepted Answer

A malignant tumor is characterized by its ability to invade and infiltrate neighboring tissues, leading to the destruction of healthy tissues and organs. Additionally, malignant cells can detach from the primary tumor and metastasize to distant sites, further spreading the cancer. In contrast, a benign tumor is often encapsulated and does not invade neighboring tissues or spread to other parts of the body, making it less dangerous.
