Malignant bone tumor

Malignant bone tumor's disease overview

What is

What is malignant bone ? Bone cancer is a malignant tumor that comes from bone cells, most commonly encountered bone cancer and cartilage. Bone cancer is common in teenagers and young people, men meet more than women.

Can

malignant bone tumor be cured? Bone cancer is now considered to be treated with a survival rate of 5 years from 60-70%.

Causes of Malignant bone tumor's disease

Causes of bone cancer , currently unknown. The factors are considered to be related to the risk of disease including:

Ionization radiation: is a physical agent from the external environment causing cancer, accounting for about 18% of all bone cancer. The impact of bones, trauma due to sports, traffic accidents. In some cases, bone cancer develops in the impact area or fracture. Development and time are too short to appear cancer caused by environmental factors.

Paget disease of bone: It can be seen in the breast and skin. Paget disease in the bone progresses into cancer after 40 years of age

Bone dysplasia

Classification of bone cancer includes:

Bone cancer

Cartilation cancer Malignant giant cell tumor

Sarcom Ewing disease

Li> Vascular cancer

Bone cell cancer: fibers, fat sarcom, malignant medium tissue

Symptoms of Malignant bone tumor's disease

Common disease in young people, especially children with a height larger than other children of the same age

common location: The end of the thigh bone and the tip of the tibia. The less common position is the head on the femur and head on the arm bone; Flat bones or bone cancer are pelvis and shoulder blades.

Common bone cancer symptoms include:

Pain: is the most common symptom with the nature: Early the early patient pain is vaguely then pain then constantly causes the patient to lose appetite, insomnia, use painkillers without pain. decrease. U fastening the area of the region with tumor. Interfected tumors organize software, clearly the blood vessels under the skin and newly created small vessels. The stage later than the tumor can be infected to break the stomach face, bleeding causing superinfection.

People at risk for Malignant bone tumor's disease

People with a family history of malignant bone tumors

People with a history of special trauma, bone fracture, bone crash

The person with a history of exposure to ionized radiation at a long time

People with benign bone tumors are at risk of malignant change: bone paget, bone disorders

Prevention of Malignant bone tumor's disease

There is no specific bone tumor prevention. Some of the following measures can be applied:

Treat the fractures at a reputable medical facility, go to the regular check -up according to the appointment

Periodic examination when there are signs of suspicion is not as clear as pain. Bones sometimes in teenagers, especially people with a family history of disease

monitoring in patients with benign bone tumors such as bone paget, bone dysplasia

Diagnostic measures for Malignant bone tumor's disease

Tests in diagnosis of bone cancer include:

Bone X -ray:

must take both straight films and tilted movies. Take side by side for comparison. It is possible that the bone -shaped, rodents and loss of calcium of the bone

Signs of bone creation: Alternating with bone pepper, it is easy to confuse with bone inflammation. Bone membrane: Not a specific sign of bone cancer. In irregular cancer, breaking the membrane or not seeing the trace of the bone membrane due to the cancer invaded into the software.

The spread of the total trade in the bone, in the bone marrow and outside the bone. Valuable than magnetic resonance is the detection of bone cancellation under the shell, the fractures are hard to see

Magnetic resonance imaging: evaluating the spread of tumors in the bone marrow, into soft tissue, nerve invasion, blood vessel invasion.

Bone radiation scan: Determine the limit of damage, monitor the progression of lesions and the effectiveness of chemical treatment. Phát hiện các ổ di căn, đặc biệt là di căn xương

Pathological tissue test: There is a diagnostic value, determining the type of pathology of bone cancer.

Testing for alkaline phosphatase concentration: increases when there is a bone cell activity. Testing has the role of monitoring and prognosis. After treatment if alkaline phosphatase increases again to think about recurrence.

Distinguishing diagnosis of bone cancer includes:

Acute osteomyelitis: Due to staphylococcus up to 75%, then streptococcal soluble streptococcus. Patients increase local pain, swelling of software. X -ray has losing boundaries of tissues, loss of bone minerals, changing bone structure. Examination of bone marrow and bone membrane to transplant bacteria to help diagnose the disease. bone shape. Clinically has fever, increasing blood rate. Suction tumors with pus, culture to find bacteria. Cancer often metastasized to bone include: lung cancer, breast cancer, prostate cancer ...

Malignant bone tumor's disease treatments

Bone cancer treatment includes the following methods:

Surgery:

Surgery to conserve spending: remove the tumor and recover the lost bone or replace fake bones. Indicated when bone cancer is localized, invasive nerves and blood vessels

amputated surgery, removing joints applied in the following cases: There is vascular and nervous lesions of the limb. Pathological fractures are at risk of sprinkling bone cancer cells if conservation surgery is easy to relapse in the wrong position, leading to contamination to healing organization, infection in lesions too wide into the software , not responding to children's chemicals under 12: Consider the amputation because the bone conservation thrives causing the difference in length too much later.

Chemicals:

Chemicals Pre -surgery: Helps shrink Nguyen Phat tumor to facilitate surgery to preserve spending, control of metastases

Chemicals after surgery: Reduce recurrence Special place in conservation surgery. Restricted metastasis.

Radiation:

Determine the case of failure to surgery

Local radiation has the effect of relieving pain and development of U

prognosis of bone cancer depends on the following factors:

The location of cancer: The far end of the limb is better than the beginning

The pathology of the pathology and the stage of the tumor

Treatment method: Pre -surgical and surgical substance for good prognosis.
