Man is composed of tissues. Tissues are made
up of cells. And the diseases occur in cells. Cytology is
study of cells, a study of the cell at core. Light
microscope is a powerful tool and can detect most
morphological changes at cell level. Even the chemical
changes, not visible can be detected through various
immunological and hybridization techniques at cell
level. Cytology is therefore a very useful technique
and mode of study. The study of peripheral smear of
the blood in practice for so many decades is a form of
cytology and of course bone marrow too.
