What is bone cancer and what are the manifestations of bone cancer

Bone cancer refers to the presence of lesions and tumors in the skeletal system, followed by metastatic lesions that need to be considered as metastases to other organs to the bone. For the patient, MRI examination and bone scan examination are required, if the patient is a single lesion, surgery can be taken**, postoperative chemoradiotherapy is required**, if it is multiple lesions, a combination of chemoradiotherapy is required**, and if there is pain, painkiller drugs** are required to relieve the patient's symptoms.

Bone tumors are tumors that develop in the bones or their appendages. There are benign and malignant. Malignant bone tumors, which are often referred to as "bone cancers", develop rapidly, have a poor prognosis and a high mortality rate.

Malignant bone tumors are classified as primary and secondary. Malignant tumors that metastasize from other tissues or organs in the body to bones through the blood circulation and lymphatic system are secondary malignant bone tumors. There is also a type of lesion called neoplastic lesion, the tissue of the tumor-like lesion does not have the characteristics of tumor cell morphology, but its ecology and behavior are destructive to the tumor, which is generally more limited and easy to **.

Bone Cancer Symptoms:

1. In the early stage of bone cancer patients, a hard lump will appear on the surface of the bone, with or without pain.

2. Bone cancer patients will have bone and joint pain or swelling in the early stage, which is often intensified at night and is not necessarily related to activity; The pain can be a constant, dull ache or pain that is only felt when pressed.

3. Pathological fractures or deformation may occur in early stage of bone cancer patients.

4. Patients with bone cancer will have fever, weight loss, fatigue and reduced mobility in the early stage, which sometimes occurs in advanced bone cancer, while benign bone cancer usually has no pain symptoms.

5. Patients with bone cancer have persistent and unexplained back pain in the early stage. It may just be a back problem or back pain.

6. Patients with bone cancer have one or more fractures in the early stage without obvious causes. After the fracture is broken, it should be checked for osteosarcoma or osteoporosis.

7. In the early stage of bone cancer patients, there will be numbness in the distal limb due to compression of the nerve and blood vessels.

The incidence of bone tumors is still unknown, and it was previously believed that injuries, especially chronic minor injuries and slow infections, can cause bone tumors. In recent years, through experimental research, Fujinaga has used Harvey and Moloney's sarcoma viruses to make a large number of mouse osteosarcoma models, Finkel has used different types of isotopes and viruses to make osteosarcoma animal models, and some people have used radioactive materials such as radium and strontium to make osteosarcoma animal models. These astringents have been confirmed by many scholars.

The age of onset of bone tumors is 15 to 24 years old in males and 5 to 14 years old in females, which may be related to the growth of bone and endocrine development in different sexes.

In most cases of primary bone cancer, it is not identified**, but some cases may be hereditary. Certain chromosomal abnormalities and a few rare genetically related disorders are associated with bone cancer. In the past, cancer was more likely to occur at the site of a fracture or infection.

Exposure to specific carcinogens, such as chemicals such as certain dyes or paints, may increase the risk of bone cancer. High doses of radiation and certain chemical drugs, especially preparations called alkylations, may be associated with the development of certain types of bone cancer.

The earliest cases of cancer during pregnancy are not well understood, but it is generally believed to be a genetic mutation.

The most common age group of this disease is adolescents aged 12-20 years and the elderly aged 50-60 years.

It is closely related to bone express growth, genetics, viral infections and other factors, and generally occurs in adolescents around the age of 12-20.
