Bone cancer is a group of tumors that affect a skeletal system. This type of cancer is probably the rarest form of cancer. Bone tumors are more common among children and teenagers. Instead, the older people suffer from it very rarely. Bones of adult patients are usually affected by the metastases from other tumors (for instance, lung, breast, etc.) On its initial stages, the bone cancer has no obvious symptoms. The first symptoms appear during a strong growth of the tumor that causes pain due to a compression of the nearby nerve roots. Since the patients initially experience a minimal discomfort and feel no pain, they often do not pay any attention to the signs. However, over time the pain intensifies and eventually becomes permanent. Night pain is the most exhausting.
When a bone tumor grows, it extends to the tissues around the bones or to the adjacent joints. Specific thickening appears in these areas. It differs significantly from a simple inflammation when you touch it, you’ll notice that it is denser than a classical swelling caused by arthritis.
Being the most characteristic manifestation of the bone cancer during its initial stage, the pain may appear suddenly and disappear quickly, but over time it always becomes regular. Bone fractures occur even during the most common activities like walking, bending of the knees, turning to the other side while sleeping, etc. People who experienced a bone fracture as a consequence of the bone cancer, reported about a strong pain inside the bone the day before the fracture happened.
Abdominal pain and nausea are the results of hypercalcemia. Calcium salts of the degrading bone penetrate into the blood vessels and cause unpleasant symptoms.
On the next stage of the malignant process, usually after two or three months after the appearance of the pain, local lymph nodes start to increase and edema of soft tissue develops. The tumor is well detectable, as a rule, it looks like a firm area surrounded by the soft tissue. An increased skin temperature may be observed in the affected area. The skin becomes pale and thinner. If the tumor size is large, vascular and marble-like drawings on the surface are perfectly noticeable.
