Dr. James Petterchak has the following 2 specialties
A pathologist is a physician who specializes in the causes and paths taken by different diseases in order to accurately diagnose an illness.
Pathologists diagnose and determine the characteristics of a disease through the study of biopsies of diseased tissue or of bodily fluids. For example, a pathologist will look at a biopsy of a skin lesion in order to diagnose or rule out skin cancer. A pathologist will also look at a Pap smear in order to check for a gynecological cancer like cancer of the uterus.
In addition to determining the cause and development of a disease, these specialists also study the changes a disease makes to a body and the consequences of those structural changes.
- Clinical Pathology
If you’ve ever provided a urine or blood sample, you’ve worked with a clinical pathologist — you probably just didn’t know it. They work behind the scenes in laboratories to examine bodily fluid specimens and detect substances or diseases. This means they're required to have a comprehensive knowledge of disease and what it looks like under a microscope.
They provide test results to your doctor, who then makes an informed decision about your diagnosis and the best treatment options for you. Without the work of clinical pathologists, doctors technically wouldn’t be able to diagnose patients as accurately as we can today. It's also worth noting that clinical pathologists are different from anatomical pathologists, who analyze tissue taken from a biopsy or entire infected areas as well as whole body parts.
