The linguistic tools the author utilizes in the text at hand are
solely grammatical and syntactic. The present tense, descriptive and
prescriptive as it functionally is, prevails throughout the text.
Scientific data are objectively presented to the reader without the
least subjective intervention on the part of the author. Present modal
auxiliaries abound in scientific texts. The author may resort to
repetitions, especially of verbal or noun construction, to link
preceding with succeeding information. An example of this is the
recurrence of the word 'techniques' in the third paragraph.
Demonstrative pronouns are used in abundance. For instance, 'this' and
'these' very often occur, not to indicate proximity but to demonstrate
a specific event. The passive form is often used when need arises for
generalization and objectivity. To exemplify this, let me quote the
second sentence in the third paragraph: "For example, it has been
estimated that some long tumours may grow for a period of ten years
before they are detectable".
The second portion of the text introduces another OMCC which is
further divided into sub-centres. It takes up almost two thirds of the
entire text. It begins with a topical sentence in which various
methods of treatment are enumerated: surgery, radiation, therapy,
chemotherapy, immunotherapy, and bone marrow transplants. Then, each
method of treatment is dealt with at length in an individual pa/agraph.
