Cancerbones - a malignant tumor which can grow in all tissues forming bone.This tumor of bone, periosteum, joints and cartilage.

share of bone cancer is approximately 1.5% of all cancers.The most common malignant tumor found in young people under 30 years old.

causes of the disease is not well established.Many experts call one of the main reasons for the previous injury.Also indicated on carcinogens provocative role in the appearance of bone cancer.Such substances include beryllium and phosphorus.

Types tumors

Depending on the localization of cancer the following types of the disease.

Osteosarcoma.The most common type of bone cancer that affects the bones of the upper and lower extremities and pelvis.Tumor cells begin to develop in the bone tissue.Usually it occurs in children and young people up to 30 years.Sometimes it is diagnosed in people 60-70 years of age.This tumo

r is more common in men than in women.

chondrosarcoma.This tumor develops from cartilage cells.Most often, chondrosarcoma affects the bones of the upper and lower extremities, pelvis.But sometimes it arises in the cartilage of the trachea, larynx, thorax.The risk of the disease get people over 20 years.Usually identify chondrosarcoma 1 or 2 stages of development.

Malignant fibrous histiocytoma.The tumor begins to develop in the soft connective tissues - tendons, ligaments, muscle and adipose tissue.This tumor is characterized by the rapid defeat of the bones of the lower or upper limbs, the tissue around the knee joint.Most often this type of cancer is common in older people.Metastatic bone cancer this type are able to penetrate into other organs such as the lungs or the lymph nodes.

Fibrosarcoma.Typically develops in the soft tissues, sometimes - bone.It affects the bones of the limbs and jaw bones.It meets middle-aged and elderly people.

giant cell tumor of bone.This type of bone cancer is more common in the knee joint.Sometimes the tumor affects the bones of the extremities.It occurs in patients with middle and old age.Giant cell tumor is dangerous by the fact that at each repeated relapse tends to capture the surrounding organs and tissues.

Chordoma.The tumor which affects the bones of the spine and skull base.Usually it occurs in people older than 30 years, mostly in men.It is developing quite slowly.Metastatic bone cancer of this type are very rare.

Symptoms of bone cancer

in the diagnosis of disease determines the called triad of symptoms of bone cancer - pain in the affected area, the existence of the same tissue neoplasms and violation of the basic functions of the limb.

One of the primary symptoms of bone cancer called pain.Bone tumors without pain are very rare.On pain of unexpressed character appears early in the disease.It usually appears suddenly and passes quickly.But for a short enough time to localize the pain begins.It is becoming more intensity does not go after a rest or fix the limb.One of the signs of bone cancer pain is the night.

With further development of the disease occur following bone cancer symptoms - body deformation in the area of ​​the tumor or the contours of the affected limb, often develop soft tissue swelling.Palpation cloth neoplasm can be detected, which is usually fixed with respect to the surrounding soft tissue.Often, the tumor is very painful, the skin on her hot, due to the development of the inflammatory process.Objective signs of bone cancer occur 2-3 months after the onset of pain.First, tumor growth is fast enough, but then it may slow down or even stop.Defined by palpation the tumor indicates the spread of tumor to the surrounding soft tissue.The skin that covers the tumor is large, thins, becomes pale with a noticeable pattern of varicose veins.Such tumors rarely grow into the skin.

frequent symptom of bone cancer is the difficulty of movement (contractures) of the affected joint and atrophy (reduction in weight and volume) of muscles.This is especially true for the localization of the tumor in the marginal parts of the tubular bones.Less broken joints function in tumor development in the middle of the bone.

metastasized bone cancer usually do not penetrate into the adjacent joint.

Treatment of diseases

main method of treatment of bone cancer is a surgical method.Not so long ago when this disease required the amputation of the affected limb.Now, surgeons remove the damaged areas, put modern prostheses, whereby a man returns to his usual life.

Current treatment of bone cancer involves surgically removing the affected part of the bone with subsequent replacement implant of metal, plastic or cadaveric bone.In the presence of bone cancer metastases in the lungs, they too were removed.During surgery, at an early stage, there is the most favorable prognosis of bone cancer.

successfully used radiotherapy in the treatment of this disease.In some types of cancer this method is used as the primary treatment.Often, radiation therapy is administered prior to surgery or after the conference.The method consists in the irradiation of cancer cells by radiation, which is devastating for them.

in treating bone cancer using chemotherapy.When using this method of treatment are administered to the patient chemotherapy - a substance having the ability to slow the growth of cancer cells and destroy them.Chemotherapy is usually performed after surgery to remove the tiny cancer metastases, which can remain in the body of the patient.Increasingly, doctors are practicing the use of chemotherapy before surgery to reduce the size of the tumor.

forecast

bone cancer bone cancer prognosis depends on many factors - localization of a malignant tumor, its size, type, degree of development, the presence of metastases.

Timely diagnosis, good treatment significantly improve the chances of curing the patient or the extension of life for a long time.

most favorable prognosis of bone cancer occurs in isolated tumors without metastasis.survival percentage is 75-80%.
