How is bone cancer diagnosed

In recent years, there are more and more cases of people waking up at night around us, and people have increased their attention to this disease. While many families are taking preventive measures at home, in order to prevent any unexpected situations, they also want to go to regular hospitals for regular check-ups. So what are the current medical examination methods for bone cancer?

1. X-ray inspection

X-ray examination is an important means of diagnosing bone cancer, and the results of the examination are an important basis for diagnosis. The shadow of a benign bone tumor is relatively regular, with uniform density, neat outer borders, and clear contours. There is no reactive shadow in the periosteum or in the soft tissue. Thinning and expansion of the osteolytic bone cortex are a characteristic of benign bone tumors. The shadow of a malignant bone tumor is mostly irregular, with uneven density, irregular borders, unclear contours, and irregular destruction of the bone cortex.

2. Pathological examination

Pathological tissue examination is considered to be a diagnostic method with a high accuracy rate. If the examination is not carried out at the right location, it may lead to a wrong diagnosis, so pathological tissue examination must be combined with clinical or X-ray examination. Commonly used sampling and examination methods include needle biopsy, incisional biopsy, frozen section, paraffin section, etc.

3. CT and MRI examinations

CT and MRI examinations can detect cancerous tissue at an early stage with a higher accuracy rate.
