Top Best Open Access Journals In Cytology
Cytology is the study of individual
cells of the body, as opposed to histology which is the study of whole human tissue itself. Strictly speaking, cytology is that the study of normal
cells and
cytopathology is that the examination of
cells within the context of disease, which is basically what we’ll be talking about but “cytology” is employed by many of us as shorthand for both, so that’s what we’ll do here. The human body is made up of millions of
cells and these can be sampled and looked at under the microscope, after suitable preparation, to help diagnose medical conditions.
Cytology is that the exam of one cell type, as often found in fluid specimens. It's mainly used to diagnose or screen for cancer. It's also used to screen for fetal abnormalities, for pap smears, to diagnose infectious organisms, and in other
screening and diagnostic areas.
The
cells to be examined may be taken through the following methods:
· Scraping or brushing the tissue surface, like during a cervical smear
· Collecting body fluids, such for urine or respiratory phlegm
Fine-needle aspirations. This is removing
cells by drawing them through a fine needle, like abdominal fluid in ascites, pleural fluid from the lungs, or spinal fluid from the vertebral canal.
Cytology is the exam of a single cell. These
cells are often found in fluid samples. Cytology is used to do the following:
· Diagnose or screen for
cancer or diseases
· Screen for fetal abnormalities
· Screen for pap smears
· Diagnose infectious organisms
· For other
screening and diagnostic areas
· Other types of tissue biopsy
Cytology is different from histology. Cytology generally involves looking at a single cell type. Histology is that the exam of a whole block of tissue.
