Cancer Cells

What is the main difference between benign and malignant tumors?

• Malignant tumors grow slowly

• Benign tumors are life-threatening

• Malignant tumors are contained to the tumor

• Benign tumors don't invade nearby tissues

Answer explanation

The main difference between benign and malignant tumors is that benign tumors don't invade nearby tissues, while malignant tumors do.

What is the main difference between normal cells and cancer cells in terms of division?

• Normal cells divide uncontrollably

• Cancer cells undergo apoptosis

• Normal cells grow and die in a controlled manner

• Cancer cells have a specific role to perform

Answer explanation

The main difference between normal cells and cancer cells in terms of division is that normal cells grow and die in a controlled manner.
