Doctor's Notes
Reviewed by Dr SHAILAJA RAGHUNATH MURDESHWAR — MBBS, MD (General Medicine) · Reg. No. 8052
"The progesterone receptor (PR) status is a key biomarker in breast cancer management. PR-positive tumors are more likely to respond to hormonal therapies, improving patient outcomes. This test is crucial for personalized treatment planning."

Sample Stability
- Sample without proper fixation
- Insufficient tissue
- Missing clinical information
Understanding Your Results
PR Positive
Indicates the presence of progesterone receptors. Tumors are likely to respond to endocrine therapy and generally have a better prognosis.
PR Negative
Indicates absence of progesterone receptors. Tumors are less likely to respond to endocrine therapy.
If you experience any symptoms of breast cancer or if your test results indicate abnormalities, consult an oncologist immediately for further evaluation and management.
