• Primary bone cancer
• Secondary bone cancer
Primary bone cancer aka localized bone cancer is the initial stage of the disease and the cancer is still in the bones. While secondary bone cancer also referred to as metastatic bone cancer is the stage in which the disease has been spread from the bones to the surrounding tissues i.e. to adjoining parts. Due to its dispersal, the secondary bone cancer has a survival rate that is much lower than that of the primary bone cancer. But with the development of modern technology and advanced treatments, the secondary bone cancer survival rate is seen increasing.
The statistics that are evolved help in making people aware about the austerity of the disease. These figures are calculated by studying a particular group of people previously suffering from the disease. Breast, prostate and lung cancers are the common types of cancers which spread into the bones. There are various symptoms and signs that ensure the presence of bone tumor like pain in the area, swelling, weakening of bones, Hypercalcaemia, muscle pain, fatigue, nausea, etc. The disease also shows symptoms that negatively influence the patient’s daily life leading to delusions, kidney stones or even death. This lowers the secondary bone cancer survival rate.
The methods in which a bone cancer can be diagnosed involve Blood tests, X rays, CT or MRI or PET scan, biopsy, etc.
The results of secondary bone cancer prognosis depend on varied factors and so does the secondary bone cancer survival rate:
1. Nature of the primary cancer: If the primary bone cancer has spread then the secondary bone cancer survival rate decreases. While if the primary cancer hasn’t spread, then the secondary survival rate is more. This can be made possible by premature discovery. Whenever a patient is seen suffering from the symptoms, he should be detected immediately.
2. Type of bone cancer: Every different type of bone cancer reveals different types of prognosis and as a result different survival rate. The type that is more fatal has low survival rate, while the ones that can be cured immediately has a survival rate that is higher. It depends on the localization of the disease.
3. Sternness of the injury: If the disease has been there in the bone for a longer period of time and it has spread to adjoining tissues and parts then the secondary bone cancer survival rate decreases. Therefore higher the sternness lower is the survival rate and lower the sternness, higher is the survival rate.
4. Treatment offered: In some cases, if a patient undergoes proper treatment and therapy and the disease is detected early, then he may survive for a time span of two to three years increasing the secondary bone cancer survival rate. While this again depends of various factors like age of the patient, his health (physical and mental), type of primary cancer, stage of the disease, its severity, etc.
