What are the auxiliary diagnosis methods for bone tumors?

Bone tumors are tumors that occur in bones or their accessory tissues (blood vessels, nerves, bone marrow, etc.). They are common diseases. Like other tissues in the body, their exact cause is unknown. Bone tumors can be benign or malignant, and there is no satisfactory treatment method to date. Bone tumors must be discovered and treated early. The following is an introduction to auxiliary diagnosis methods for bone tumors.

1. Pathological examination: Pathological histological examination is considered to be the most accurate auxiliary diagnosis method for bone tumors, but if the sampling site is inappropriate, it can also cause diagnostic errors, so pathological examination must be combined with clinical and X-ray examinations. Common sampling and examination methods include needle aspiration biopsy, incisional biopsy, frozen section, paraffin section, etc.

2. Radionuclide examination: It can be used for early auxiliary diagnosis of bone metastases.

3. CT and MRI: This auxiliary diagnosis method for bone tumors can detect diseased tissues at an early stage with high accuracy.

4. Accelerated erythrocyte sedimentation rate: Alkaline phosphatase may increase in osteosarcoma and osteoblastic metastatic bone tumors.

In short, auxiliary diagnosis of bone tumors is mainly based on clinical symptoms and X-ray examinations. For those that are difficult to diagnose, pathological examination is of decisive significance, but attention should be paid to the appropriateness of the sampling site.
