Can't bone cancer be detected by blood test

Routine blood tests are the most common and basic blood tests. Diseases are determined by observing changes in the number and distribution of the blood. It is one of the common auxiliary examination methods used by doctors to diagnose diseases. So is it true that bone cancer cannot be detected by blood tests? What other tests are needed to confirm bone cancer?

A blood test can be used to suspect bone marrow cancer, but it cannot be used to confirm whether a person has bone marrow cancer. In the early stages of bone cancer, there will be no changes in red blood cells, white blood cells, or platelets in a blood test. To confirm the diagnosis, the following tests should be performed under the guidance of a doctor:

1. Radiological examination

X-ray examination can provide valuable information for clarifying the nature, type, and extent of bone tumors and determining treatment strategies. It is an important examination method for bone tumors. Malignant tumors have irregular images, blurred edges, obvious osteolysis, bone destruction, thinning, fracture, and loss.

2. Pathological examination

Pathological histological examination is considered to be the most accurate diagnostic method, but pathological examination must be combined with clinical and X-ray examinations. Commonly used sampling and examination methods include needle biopsy, incisional biopsy, frozen section, paraffin section, etc.

3. Radionuclide examination

It can be used for early diagnosis of bone metastases.

4. CT and MRI

It can detect diseased tissue earlier with high accuracy.

5. Others

In osteosarcoma, the erythrocyte sedimentation rate is accelerated, and alkaline phosphatase may be increased in osteoblastic metastatic bone tumors.
