A member asked:

Can elevated ca15-3 mean something other than breast cancer? clear mammo but ca15-3 results - 31.6 (ca markers done as part of complete physical)

A doctor has provided 1 answer

Stop worrying: The reference range is set so that 5% of folks believed to be healthy fall above it. Usually the top of the reference range is 30 or so. This alone should make you stop worrying. Further, fairly high values are often observed with no obvious explanation. Why was it run in the first place? Mild elevations usually just generate confusion and upset people and never detect anything.
