DIAGNOSIS OF CANCER – DIAGNOSIS IN PEOPLE WITH SYMPTOMS
It is possible to find some types of cancer before any symptoms have developed, that is, while a person is still perfectly healthy and has noticed absolutely nothing wrong. This is discussed at the end of this chapter. However, most cases of cancer are diagnosed after one or more symptoms have developed. I described ni.mv of these early warning symptoms in the last chapter.
How do we go about finding the cause for such symptoms? There are two essential, basic steps. First, we have to find some of actually seeing the source of the problem. Second, if it looks at all suspicious of cancer, we have to obtain a specimen to be examined under the microscope. A word that is often used in tHerring to the trouble spot is lesion. This is a general word winch covers any abnormality, not just cancer. Because it is so Ui-neral it is a useful word to use when we don’t know exactly what the problem is.
