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.
