Benign tumors are usually cancerous growths.

• A. True
• B. False
• C. Not known
• D. Sometimes

Answer: (B)

The important idea here is the difference between benign and malignant tumors. Benign tumors are noncancerous; they typically grow slowly, are well circumscribed or encapsulated, and stay localized without invading surrounding tissues or spreading to distant sites. That’s what makes them generally less dangerous than malignant tumors, which are cancerous, invade nearby structures, and can metastasize. So the statement is not correct because benign tumors, by definition, are not cancerous. They can still cause problems if they press on nearby organs or nerves, but they do not behave like cancer by invading or spreading. There are rare cases where a benign lesion may later transform into a malignant one, but that is not the usual behavior that defines a benign tumor.
