How to check for bone cancer, what tests to do for bone cancer, and how to check for bone cancer

Nowadays, many patients don't know what to do when they go to the hospital for bone cancer screening? This situation is often seen by medical staff, and it is very important to do bone cancer examination, bone cancer examination can effectively prevent the disease, what kind of examinations need to be done for bone cancer? Let me introduce it to you now.

Bone cancer examination mainly includes the following aspects: 1. Routine physical and biochemical examinations.

2. Radiology bone cancer examination: X-ray photography, angiography, lymphovascular photography and other examinations on the lesion bones, and the supervision diagnosis of malignant osteoma and benign bone tumor is made according to the nature of the first, generally, the reliability of the diagnosis of experienced radiologists can reach 90%, especially the bone cancer examination such as computed tomography, magnetic resonance photography, angiography and nuclear medicine bone isotope scanning, which is more accurate and convenient. 3. The methods of pathological tissue section bone cancer examination can be divided into three types:

1) Acupuncture sampling bone cancer examination, the success rate is 80-90%. (2) Examination of bone cancer by incision and sampling of the affected area. (3) Excision or curettage of pathological examination

Histopathological examination is the final and correct diagnosis of bone cancer by bone cancer pathologists based on the pathological changes of the section tissue. Tips: In daily life, if there is any discomfort, it is still necessary to make an examination as soon as possible, so that it is convenient to seek medical treatment early and prevent diseases.

Bone cancer is a common name for various malignant tumors on the growing bones, it is not a specific disease, it is usually divided into two main categories in medicine. One is a malignant tumor that grows out of the bone, which is called a primary bone tumor. The other type is because other tumors enter the bloodstream after the cancer cells reach an advanced stage, and then follow the blood into the bones and form tumors in the bones, which is called metastatic cancer.

For the first type of tumor, it is still unclear at this time. For the second type of tumor, we can safely say that it is due to other cancers that have metastasized, and this ** is clear.

It can be detected in the early stage of bone cancer, so what are the precursors of pure bone cancer and how to check it?

Regarding the location of bone cancer pain, generally speaking, there will be no painful symptoms in the cancerous part in the early stage, but when the disease develops, it will lead to pain in the limbs and cervical spine, and these pains will gradually worsen, mainly showing intermittent reactions, but if you do not realize that the symptoms are not in time, this intermittent reaction will develop into a continuous one. The pain caused by bone cancer can have a serious impact on the quality of sleep at night, so that people are weak and unable to do anything.

At present, X-ray examination can provide valuable information for determining the nature, type, scope and decision of bone tumor, and is an important examination method for bone tumor. 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 sunshine-like, onion-like and Codman triangle.

For low back pain, if the doctor recommends a check-up, you should need to check the following items: 1. Blood, including liver function routine (for liver cancer and metastasis), PSA (for prostate cancer and metastasis) and so on.

2.If your uncle is accompanied by waist and buttock pain, do an ect thoroughly, a full-body bone scan, this is intuitive, ** is okay, more than 600, it belongs to radioactive examination, injection of radiological needles in the morning, film in the afternoon, go the next day, the whole body bones are clear at a glance, of course, ECT is done after confirming which part of the cancer is, because bone cancer is generally the middle and late metastasis of other cancers!

May your family be healthy!

Hello: Bone tumors are clinically painful. Pain is the most significant manifestation of rapid growth.

Benign tumors are usually painless. Benign local masses and swelling are often firm and nontender, with slow growth. Local masses and masses develop rapidly, and are more common with malignant dysfunction and compressive symptoms.

To diagnose bone cancer, three tests are required. First of all, the patient should be subjected to a strict physical examination, and the part of the patient with bone cancer will have obvious swelling and pain, and the bones in different parts will show different clinical manifestations. Secondly, X-ray examination is required for the site where bone cancer occurs to preliminarily determine the location of the tumor.

CT examination of the diseased tissue can also be performed to show the size and location of the tumor more clearly. Third, the final definitive diagnosis requires the acquisition of diseased tissue for pathological examination.

The main clinical manifestations of bone cancer are pain, pathological fractures, limb numbness, paresthesia and even limb paralysis or paraplegia, and anemia. According to your description, it is still necessary to be highly vigilant, and it is recommended to go to the hospital for examination in time. Strive for early diagnosis and early **.

The content of modern Chinese medicine is about 16% ginseng essence extract), which can well improve the immunity of the elderly, increase the body's tolerance, and has a good effect in preventing cancer, relieving pain, and relieving vomiting, which can be said to kill two birds with one stone.

1. Metastasis symptoms: Benign bone tumors generally do not have metastasis symptoms, while primary malignant bone tumors are prone to metastasis of various tissues, organs and other bones.

2. Neuritis: Rare in clinical practice, numbness is sometimes mild and sometimes severe, and there is no bone destruction in X-ray examination.

3. Development process: benign bone tumors generally develop slowly, and some can stop developing after a certain extent; Malignant tumors develop rapidly and have strong ring detention, and with the continuous increase of malignant bone tumors, they mostly show superficial venous distention.

4. Alveolar abscess: there are lesions and local redness, swelling, heat, pain and dysfunction, but there is no numbness of the lower lip.

5. Chronic osteomyelitis of the jaw: patients with a history of inflammation can see repairing changes of bone destruction and periosteal hyperplasia on X-ray examination.

6. Overall presentation: patients with benign bone tumors are generally in good condition, with normal body temperature, erythrocyte sedimentation rate and blood count, and only a few patients will have pain; Patients with malignant bone tumors mostly present with increased body temperature, emaciation, anemia, obvious pain symptoms, and rapid erythrocyte sedimentation rate, and cachexia is more likely to appear when malignant bone tumors develop to an advanced stage.

7. X-ray imaging: benign bone tumors have a clear boundary under X-ray, and there is often a clear demarcation line between them and normal bone, and there is generally no periosteal reaction, while malignant bone tumors show unclear boundaries and unclear boundaries with normal bone, and periosteal reactions are disordered, mostly manifested as sunlight radiation.

8. Mandibular central hemangioma: X-ray imaging shows that the mandible is flare-like changes and the mandible is enlarged.

Bone cancer is a malignant tumor that occurs in the bone or its accessory tissues (blood vessels, nerves, bone marrow).

1. X-ray examination. 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 benign bone tumor is relatively regular, the density is uniform, the peripheral boundary is neat, the contour is relatively clear, the periosteum has no reactive shadow, and there is no shadow in the soft tissue, and the thinning and swelling of the osteolytic bone cortex are a characteristic of benign bone tumor.

The shadow of malignant bone tumor is mostly irregular, the density is uneven, the boundary is not neat, the contour is not clear, and the bone cortex is irregularly destroyed.

2. Pathological tissue examination. Histopathological examination is considered to be a diagnostic method with high accuracy. If the examination is not done properly, it can lead to an incorrect diagnosis, so the pathological examination must be combined with clinical or x-ray examination.

Commonly used methods include needle aspiration biopsy, incisional biopsy, frozen section, paraffin section, etc.

3. Bone marrow aspirate examination. After puncture, cancer cells can be seen, the number of which is more than 5% 10%, and when the number exceeds 20%, atypic plasma cells are seen, and plasma cells are in the form of small clumps. Osteosarcoma and osteogenic metastases form a large amount of new bone, so the alkaline phosphatase value increases.

4. CT and MRI examination. CT and MRI can detect cancerous tissues earlier and have a higher accuracy rate.

With the progress of the times, people's living standards are getting higher and higher, and in recent years, there are more and more patients with bone cancer, and most of the obvious symptoms of bone cancer patients have reached the middle and advanced stages. Even if you don't have a medical condition, take it seriously. So how do we get a diagnosis of bone cancer?

The following is a brief introduction for you: The diagnosis of bone cancer is relatively easy, and a preliminary diagnosis can be made based on clinical examination alone, such as superficial, osteoma or osteochondroma, etc., and some have characteristics on X-ray, and can get a preliminary impression according to typical X-ray observations, such as sclerosing osteosarcoma, chondrosarcoma, etc.; In some cases, a combination of clinical, X-ray and pathological analysis is required to make a correct diagnosis. Therefore, clinical, x-ray, and pathological are considered to be the three important steps in diagnosing bone tumors, and sometimes they are indispensable.

In particular, before considering limb amputation surgery, it is generally necessary to confirm the diagnosis through the above three aspects of the examination. In the differential diagnosis, the disease should first be distinguished from inflammation. There are four main points for the diagnosis and differentiation of bone cancer:

1) Systemic reactions: patients with acute inflammation often have elevated body temperature and increased white blood cell count, and patients with benign bone tumors have normal body temperature and normal blood count. Patients with certain bone malignancies, such as undifferentiated reticulocytic sarcoma or rapidly growing malignancies, also have elevated body temperature and elevated white blood cell counts.

Acute and chronic inflammation and erythrocyte sedimentation rate (ESR) are often increased, benign bone tumors are usually normal ESR, and patients with malignant bone tumors are often rapidly erythemated. (2) Development process: inflammation gradually subsides after developing to a certain extent or after anti-inflammatory**, some benign bone tumors can stop developing after developing to a certain extent, malignant bone tumors continue to develop and destroy, and those that stop or disappear on their own are extremely rare, which is one of the diagnoses of bone cancer.

3) Local palpation: inflammation often produces abscesses, which are generally soft and fluctuate obviously. Bone tumors are generally hard or tough, solid to the touch, clear borders, and the bottom of the grave is mostly adherent to the bone and cannot be moved.

However, some malignancies with abundant blood vessels or bleeding may also be sensationally fluctuating. (4) puncture; Abscess puncture usually aspirates pus, and pus can sometimes be detected by pus culture or smear staining. Tumor puncture can only suck out blood, and puncture with a thick needle can sometimes suck out tumor tissue fragments, which is one of the diagnostic methods for bone cancer The above is a brief introduction to the diagnosis of bone cancer.

Bone metastases can occur in bone tissues anywhere in the body, with vertebral bones, pelvic bones, and ribs being more common.

First of all, after cancer patients have pain or unexplained fractures, they should quickly do a skeletal system examination to determine whether there is bone metastasis or the severity and type of metastasis. Regular x-rays, CT, MRI or bone ECT can be done, and PET-CT is a good option if you can afford it.

Whole body bone scan, needle biopsy.
