DIAGNOSIS OF CANCER – INTERNAL CANCERS (SIMPLE X-RAYS) PART 2
So, for example, what do we see on a chest X-ray? The air in i he lungs and around the body looks black, because all the X-rays get through the air. The heart and big blood vessels look greyish-white (a few X-rays get through). The bones of the ribs and spine look very white (hardly any of the X-rays get through). A solid irea in the lung is easy to see. It looks white against the black of the air in the normal lung around it. Weaknesses in bones are also fairly easy to see— more X-rays get through the softer bone. The weakened part shows as a grey area in the normal white bone. Because very few X-rays get through bones and some of the lurger organs, it is often necessary to take X-rays from more than one angle to get a complete picture. For example, if we want to Bee’ the part of the lungs that lies behind the heart we need to lake an extra X-ray from the side of the body as well as the front-to-back one.
Unfortunately, in many parts of the body it is very hard to see an abnormality on a simple X-ray. This is the case when the abnormality lets through as many X-rays as the normal part, because it is the same density. For example, cancer spots in the I idney are not much harder or softer than the normal kidney. On in X-ray they come out white and so does the normal kidney.
This means you can’t see them. The same applies to the brain, liver, stomach, bowel, pancreas and many other organs. What can we do to overcome this problem?
