How to effectively diagnose bone cancer? 3 imaging tests for bone cancer
How to effectively diagnose bone cancer? Bone cancer is a malignant tumor that occurs in the bone or its appendages, which develops rapidly, has a poor prognosis, and has a high mortality rate. For the diagnosis of bone cancer, commonly used medical methods include X-ray, CT, magnetic resonance, pathological examination, etc. Today, we are going to focus on imaging tests for bone cancer.
Imaging tests for bone cancer
1. X-ray examination.
X-ray examination can provide valuable information for determining the nature, type, and scope of bone tumors and determining treatment strategies, and is an important examination method for bone tumors.
The image of malignant tumors is irregular, the edges are blurred, the osteolytic phenomenon is more obvious, the bone is destroyed, thinned, fractured, and missing, and the primary malignant tumor often has a periosteal reaction, and its shape can be sunlight radiation, onion skin and Codman triangle.
2. CT and magnetic resonance
It can detect diseased tissues earlier and has a high accuracy rate.
3. Radionuclide examination
It can be used for early diagnosis of bone metastases.
The diagnosis of bone cancer is closely related to the patient's age, gender, location and detailed medical history. When the bone cancer is located in the superficial area, it can be confirmed by X-ray, and some bone cancer diagnosis requires multi-step diagnosis, including clinical, X-ray, pathological and comprehensive analysis, before the final diagnosis can be made.
Next, let's learn about some common manifestations of bone cancer in the early stage, and if the following symptoms appear, it is necessary to seek medical attention in time to diagnose it.
Common symptoms of bone cancer in the early stages
1. A hard lump can be felt on the surface of the bone, with or without pain.
2. Bone and joint pain or swelling, and often aggravated at night. These symptoms are not necessarily activity-related, and pain may be felt only when compressed or persistent.
3. Spontaneous fractures, caused by changes in bone structure caused by multilineage tumor growth and weakened bearing effect.
4. Fever, weight loss, fatigue and reduced mobility, etc., such symptoms can also occur in the advanced stage of bone cancer.
In addition, if the following conditions occur, it is also possible that they are early symptoms of bone cancer, and it is recommended to seek medical attention as soon as possible and do relevant examinations to confirm the diagnosis, so as not to delay treatment.
1. If there is unexplained back pain and it is ineffective after treatment, the spine should be checked for tumor.
2. If there is one or more fractures without obvious reasons, osteosarcoma or osteoporosis should be checked after the fracture is treated.
