Question: can you tell if you have cancer from an x ray?
Answer: X-rays can be used to look for and examine some types of tumours. Most tumours are soft tissue and do not show up well on x-ray. Lung tumours show up well because of the air around them in the lungs. An x-ray cannot always show the difference between a cancerous (malignant) tumour and a non-cancerous (benign) tumour.
