Human body comprises 206 bones. Each of the bones has special functions. Bones shape our body. We will not be able to move, stand and sit without the bones. Skull safeguards the brain whereas vertebrae of the spine safeguards spinal cord.
Several small structures (cells) form our body. Our body comprises various types of cells. Growth of different cells helps to spur the growth of various parts of our body. New cells are formed during normal growth process. The damaged and old cells are replaced with new cells during our entire life. A healthy body controls the growth as well as division of cells based on its needs. In a cancer patient, cells divide on their own after losing control. The cells function abnormally in a cancer patient.
Various types of cancer affect our body. If the cells are out of control in lungs, such cancer is called lung cancer. If the cells behave abnormally in breasts, such cancer is called breast cancer. A tumor is formed by abnormal cells collection. All types of tumors are not cancerous. Some tumors may be cancerous. Benign tumors don’t spread to other parts of the body and are less dangerous. Malignant tumors spread to various parts of the body and are more dangerous. Cancer cells move to other parts of the body from their initial location. The ability of cancer cells to relocate to other location within the body is called metastasis. The cancer cells in the prostate, breast, kidney, thyroid and lung may spread to bones. Hence, bone cancer is caused due to spreading of cancer from other parts of the body. True bone cancer is very rare. We need to identify whether cancer is formed within the bones or spread from other parts.
Bone cancer may be caused due to the problem with cells that form the bone. Alone in USÂ more than 2000 patients are identified with bone cancer every year. Bone cancer generally affects adolescents and children. Various types of bone tumors include chondrosarcoma, fibrosarcoma, osteosarcoma, malignant fibrous histiocytoma and chordoma. Osteosarcoma generally affects males aged between 10 and 25 years. It is the most common bone cancer.
Ewing’s sarcoma affects young people aged between 4 and 15 years. It is the most serious bone cancer. It generally affects males. The survival rate for this cancer is 65%.
Bone Cancer Symptoms
We may feel pain in the bone initially. It may aggravate over the months and years. We may also feel a lump or mass in the tissues surrounding the bones or on the bones. It may weaken the bones causing fracture. We may also suffer from night sweats, chills and weight loss.
Consult your physician if you have any symptoms mentioned above. You may need to give details about medical history to the physician. The doctor may conduct various medical tests including X-rays and CT scan to identify bone cancer and to prescribe medicine.
