CA is used to denote which medical condition?

• A. Cardiac arrest
• B. Cancer, carcinoma
• C. Calcium
• D. Cerebral aneurysm

Answer: (B)

In medical shorthand, CA is most commonly used to denote cancer or carcinoma, especially in oncology and pathology contexts. You’ll see CA in references like tumor markers (for example, CA-125, CA 19-9) and in pathology notes where carcinoma may be abbreviated as CA or simply cancer. Calcium is represented by Ca (capital C and a lowercase a), so uppercase CA doesn’t indicate calcium. Cerebral aneurysm and cardiac arrest aren’t standardly abbreviated as CA in general practice, making cancer the most consistent and recognizable meaning for CA.
