Bone cancer

Brief description of bone cancer

 Symptoms of bone cancer

Bone cancer is perhaps the most rare form of cancer. At risk are mostly children and adolescents; very rare cases of bone cancer the elderly. In adults, bone loss can occur due to malignant cells of affected organs (lung, breast) - the so-called metastatic tumors. Tumors arising directly on the bones is called the primary.

There are two types of bone cancer: malignant and benign. Benign tumors grow slowly and normal bone surrounds its bone health. Malignant neoplasm of bone is torn edges, and is rapidly increasing in size, affecting a growing portion of the bone.

Symptoms of bone cancer

Severe or moderate pain that occurs at the beginning of the disease, often causes people to seek medical attention, which, in turn, determines the existence of tumor. The pain may be dull or aching; It may be constant or occur intermittently. Among other symptoms of bone cancer - limited movement and swelling of limbs and joints. There are fractures even with minor falls. Often nausea and abdominal pain caused by hypercalcemia (in times when the calcium salt of the affected bone into the bloodstream). In the later stages of the disease there are other symptoms of bone cancer - weight loss and fever.

To distinguish several types of malignant tumors, among which there are very aggressive, and developing rather slowly.

Osteosarcoma - the most common of all cancers, bone, quite aggressive (may spread to the lungs). There is a male on the long bones of legs and hands, close to the joints. Diagnosis "osteosarcoma" may have noticed on the X-ray structural changes in bone.

Chondrosarcoma - is a kind of bone cancer that can develop as a very slow and very fast. Common among people older than 40 years. Typically localized on the thighs and pelvis. Metastatic bone cancer of this type can spread to the lymph nodes and lungs.

Chordoma - one of the rarest types of cancer. It occurs mainly in people over 30 years, is localized in the lower and upper spine.

Diagnosis of bone cancer

A complete picture of the disease - the key to successful treatment, so the exact description of the symptoms in the diagnosis of bone cancer can help the doctor identify the cause of the disease. In the early diagnosis of bone cancer need to undergo a full medical examination and blood test. In the diagnosis of bone cancer, to identify the type, size and shape of the cancer, the doctor gives the direction of an X-ray. If an X-ray revealed the seal (thickening) of bone tissue and surrounding soft tissue, the patient is sent to the additional diagnosis of bone cancer. CT (computed tomography) or MRI (magnetic - resonance imaging) are modern methods of investigation and allow to study in detail the bone tumor and surrounding tissue.

Treatment of bone cancer

 Treatment of bone cancer radiation therapy

Before you start the treatment of bone cancer, doctors take into account several factors: the type of aggressiveness, size and location of the tumor and the presence of metastases.

Surgery, radiation therapy or chemotherapy - these methods of dealing with bone cancer are effective both individually and together.

Surgical treatment of bone cancer involves the removal of the entire tumor, ie, ablation of the bone. It is not allowed to leave the affected areas, otherwise the remaining cancer cells continue to grow and develop. Removed and part of the surrounding tissue, as well as parts of the nerves and blood vessels. Amputated part of the bone can be restored with bone cement in small areas or metal implants, if you delete a large part of the bone.

Chemotherapy for cancer bone appointed doctor - oncologist, who will pick up an effective and safe dose of chemotherapy drugs. They are administered intravenously, and suppress the vital activity of cells of bone cancer. Chemotherapy is effective before the operation and after it. In the first case it reduces tumor, thereby facilitating surgical intervention; in the second case it combats remaining after surgery malignant cells.

The essence of radiation therapy is to ensure that the direction of X-rays to destroy cancer yrs. Rays enter the body in small doses that side effects were minimal.

I must say that in recent years the survival rate of patients with bone cancer (and cancer patients) increased. In many respects it is a merit of advanced discoveries in the field of radiosurgery, the rapid development of technologies and new approaches to the treatment of cancer. Prediction of bone cancer with proper and timely treatment is favorable.
