Could you tell me what are common late stage symptoms of cancer?

Check hospice sites: Some hospice sites give guidance on the dying process which is seen in late stage (or end stage) cancer or any other disease process. Quick search found this site: http://www.Hospicefoundation.Org/deathsigns. Common early findings include irreversible anorexia, weight loss, fatigue, lethargy, and so on. These all indicate that the body is slowly shutting down, especially if no reversible causes.
