What term means a cancerous tumor?

• A. Baroreceptor
• B. Carcinoma
• C. Bifurcation
• D. Bacteriophage

Answer: (B)

Carcinoma refers to a cancerous tumor that originates from epithelial tissue, the cells that line organs and surfaces of the body. This is the familiar type of cancer seen in many organs, such as the skin, lungs, breast, and colon, and it tends to invade nearby tissues and spread to other parts of the body.

The other terms point to completely different things: a baroreceptor is a sensor that detects changes in blood pressure; bifurcation is where a vessel or airway splits into two branches; a bacteriophage is a virus that infects bacteria. None describe a cancerous tumor, so carcinoma is the correct term.
