What is bone cancer?

bone cancer is an abnormal growth of cells that occur in bones. There are two main forms: primary cancer begins in the actual bone itself and is relatively rare, while the secondary is caused by cancer elsewhere in the body that spreads to the bones. It should not be confused with leukemia, which is bone marrow cancer.

In the body, old cells are constantly decomposing and replacing with new ones. If there is an abnormality in the new cell, causing it to grow and replicate much faster than usual, a tumor may develop. There are both benign and malignant tumors that grow in cells. Benign tumors are not cancer and will not spread to other tissues while malignant will be. Benign tumors can often be removed by surgery. Each type has different properties and healing differently. Malignant cancer is commonly called sarcomas.

The most common type of bone cancer is osteosarcoma that begins in cells that grow newU Bone Tissue. Most often it occurs in the knees, arms or pelvis. This form of cancer often evolves in young people under 30 years of age more than women. In the middle age it is rare and has a very low incidence of adults in their 60s and 70 years. Osteocoma is usually spread to other parts of the body, especially to the lungs.

chondrosarcoma is the second most common type and starts in cartilage cells, so it can develop anywhere where this tissue is found. In most cases, this is a slow -growing cancer, so it is unlikely to spread to other parts of the body before treatment. Chondrosarcoma is rare in young people, but the risk increases from 20 years to about 75 years. Men and women have the same chance of developing it.

The third most common type of primary bone cancer is Ewing's sarcoma. This form tends to start in bone cavities, especially in the legs, pelvis and thoracic wall, but can grow in other tissues. It is most common in children and adults under 30 years of age. Cancer grows very fast, which she eats uIt makes it possible to spread to other organs and tissues throughout the body.

chordomas are found in the base of skulls or vertebrae that form the spine. This type of cancer tends to slowly grow, but if it is not treated carefully and completely removed, it will return to the same area repeatedly. In people under the age of 30, it is unusual and men are about twice as likely to develop it.

There is no single factor that could be said to cause bone cancer. While cancer is often diagnosed after bone injury, injury is not the cause - only an indicator. There are several risk factors for the development of this form of cancer, including genetic disposition, when they had benign bone tumors or non -lawyer bone disease and underwent previous radiation treatment or chemotherapy, especially when they were young. Some people will develop primary tumors without having any of these risk factors.

The most common symptom is pain in the affected area. Initially may bePain intermittent, but as the tumor grows, deteriorates and occurs more often. Swelling may occur around cancer, usually weeks after the start of pain. Due to the location of the tumor, it is often difficult to feel any real lump. Detection of this cancer is not easy and is often diagnosed with biopsy of the painful area.
