Prostate cancer is cancer of which gland?

• A. Liver
• B. Prostate gland
• C. Kidney
• D. Lung

Answer: (B)

Cancers are named for the tissue or organ where they originate. Prostate cancer starts in the prostate gland, a male reproductive organ that surrounds the beginning of the urethra and helps produce semen. Because the cancer arises from the prostate tissue, it’s called prostate cancer. The other options are cancers named after their respective organs (liver, kidney, lung), which would be chosen only if the cancer originated in those organs. Most prostate cancers are adenocarcinomas, reflecting the glandular nature of the tissue.
