Onc/o denotes:

• A. Tumor, mass
• B. Spinal cord
• C. Lymph
• D. Intestine

Answer: (A)

Onc/o is a combining form meaning tumor or mass. It comes from a Greek root used in terms like oncology (the study of tumors) and oncologist (a doctor who treats cancer). It signals a cancer- or tumor-related context, not anatomy like the spinal cord, lymph, or intestine. For those parts, different roots are used: myel/o for spinal cord (and sometimes bone marrow), lymph/o for lymph, and enter/o for intestine.
