The first symptom of bone cancer is usually pain or tenderness near the cancer. Bone pain is caused by stretching of the periosteum (thick membrane that covers bone) by the cancer, or by stimulation of nerves within the bone. Bone pain may be hard to differentiate from ordinary low back pain or arthritis.

Their culture collapsed and Greece went through a dark period, much like the Dark Ages in Europe after the fall of the Roman Empire.
