How do X rays detect bone cancer?
X-rays only show up dense areas in the body such as bone. An x-ray may show tumors in the lung as they show up as dense white patches and they can show bone erosion in people with bone tumours but they can't show up tumours which are the same density as the surrounding organs such as liver or kidney tumours. Similarly some cancers are carried in the blood or lymphatic system and these will also not be distinguishable on an x-ray. Other procedures can be used to outline these tumours, such as the use of x-ray dyes, CT scans or ultrasounds.
