What is a neoplasm?

A. Another word for a malignant tumor
B. A type of carcinoma that grows only in the mouth
C. Any new and abnormal growth
D. A benign swelling of epithelial cells

I think the answer is (A) is this correct?

neoplasm (NEE-oh-PLA-zum)

An abnormal mass of tissue that results when cells divide more than they should or do not die when they should. Neoplasms may be benign (not cancer), or malignant (cancer). Also called tumor.

I don't think so. Your definition states that it may be benign (not cancer).

Here's the definition from Dictionary.com:

"ne⋅o⋅plasm  /ˈniəˌplæzəm/ Show Spelled Pronunciation [nee-uh-plaz-uhm] Show IPA
–noun Pathology. a new, often uncontrolled growth of abnormal tissue; tumor."

Please rethink this answer.

I understand what your saying so the answer would be (c)

thanks

Right. It's c.

Yes, you are correct. A neoplasm is indeed another word for a malignant tumor. So the correct answer to the question is option A.
