Breast fibroids do not cause elevated blood sedimentation, there is no direct correlation between the two, and other causes should be considered for elevated blood sedimentation. The speed of blood sedimentation is mainly related to the blood flow rate and blood viscosity, the higher the blood viscosity, the faster the blood sedimentation will be. The higher the viscosity of the blood, the faster the sedimentation rate will be. The body is in a state of hypercoagulability, and an increase in fibrinogen may cause the sedimentation rate to accelerate; inflammation, immune system diseases, and malignant tumors may also cause the sedimentation rate to accelerate. Breast fibroadenoma does not affect the blood markers and does not cause elevated blood sedimentation. If you have breast fibroadenoma with recent localized pain and elevated blood sedimentation rate, you need to consult a doctor for further diagnosis and standardized treatment under the guidance of a clinician to avoid delaying your condition.
