Primary bone cancer is a type of cancer that starts in the bone and is quite rare. The prognosis of primary bone cancer depends on various factors including the type, site and stage of the cancer.
The type of bone cancer is classified by the type of cell in which it occurs in and makes connective and supporting tissues of the body, like cells of the bone, muscle, cartilage and ligaments.
A doctor suspects that a person has primary bone cancer based on the symptoms that can be seen like, pain, swelling in a bone close to the skin which has the cancer, tiredness, problems in movement, weight loss. He then conducts a number of tests to confirm this diagnosis. These may include.
On confirmation that a person has primary bone cancer, more tests are usually done to see whether the cancer has spread, by more x-rays, blood tests and scans.
Once the type of cancer has been identified, it is graded according to whether it is likely to remain in the bone or whether it is more aggressive and likely to spread to other organs in the body. If it has spread then it is no longer a primary cancer and it is a higher stage cancer, such as Stage 2, Stage 3 and so on. The subsequent treatment and the prognosis will depend on these. The International Staging System may be used to predict survival, with a median survival of 62 months for Stage 1, 45 months for Stage 2 and 29 months for Stage3.
The treatment options for primary bone cancer are surgery, chemotherapy and radiotherapy. The of primary bone cancer prognosis: it is difficult to give an overall outlook. Each individual case is different and the success of the treatment depends on the type, site and stage of the cancer. The earlier the stage, the better is theprognosis. With advances in surgery and chemotherapy the outlook for primary bone cancer prognosis has tremendously improved in the last 20 years.
