Pls hematologist opinion needed I am writing u a biopsy report pls kindly tell me what it means bone marrow biopsy15 percent plasma cells?

Suggests myeloma. An increased number of plasma cells in the bone marrow is most worrisome for multiple (plasma cell) myeloma. With 15% plasma cells, correlation with clinical findings and imaging would be necessary to diagnose as this disease tends to present on a spectrum and clinical findings are important. Please consult with your hematolgist/oncologist for better understanding and how to proceed.
