Bone cancer is an uncommon cancer that forms in the bones. Bone cancer can occur in any bone of the body, most commonly it affects the long bones such as in the arms and legs. The term ‘bone cancer’ doesn't include cancers that begin elsewhere in the body and spread to the bone.
Several thousands of people are diagnosed with bone cancer annually. Stage 4 bone cancer means that the malignancy has reached the advanced stage and the cancer cells have spread to other parts of the body such as lungs. The prognosis of stage 4 bone cancer is not easily predicted.
When a bone tumor grows, it exerts pressure on the healthy bone tissue. This can destroy the tissue and the patient may feel pain and experience other problems such as discussed here. These conditions may aggravate the experience of pain in night time if you have bone cancer even though you might relax well.
Bone metastasis occurs when cancer cells from the primary tumor spread to the bone. Common cancers that are likely to spread to bones are prostate cancer, breast cancer, kidney cancer, thyroid cancer, and lung cancers. The bone is a common site for metastasis of other types of cancers.
