How to Use This Calculator
- Enter baseline tumor marker value (e.g., PSA, CEA, CA-125 in appropriate units) and date.
- Enter follow-up values and dates at each monitoring interval.
- Read percent change from baseline and doubling time calculation.
- Rising markers with shortening doubling time may indicate disease progression requiring evaluation.
- Use marker trends alongside imaging to guide treatment response assessment.
