Pathology tests are tests to look at samples of the body's tissues under a microscope. The tests help your doctor find or check on a condition.
The tissue may come from a biopsy test, where a small piece of tissue is removed. Or it may come from removing an abnormal area (like a mole). It may even come from a whole organ.
Blood, body fluids, and scrapings (like a Pap smear) may also be tested.
Other tests may be done on a sample. These can include chemical tests and DNA tests to look for problems with genes.
A pathologist is a medical doctor who looks at tissue, blood, and body fluid samples to help find out if you have a disease. He or she may also do autopsies.
A pathology test on a tissue sample, blood, or body fluid is done to:
A doctor can find out if a problem is cancer, and if so, what type of cancer it is. A doctor also can learn if symptoms are coming from a different problem, such as infection or inflammation.
When a doctor looks at tissue under a microscope, he or she can see if the cells don't look normal. The doctor also can find out if a problem has spread within an area or to other areas. What the cancer cells look like under the microscope can also help the doctor stage a cancer. Staging is a process that doctors use to describe how severe a cancer is.
Your doctor can keep track of changes in your health by looking at tissue samples over time.
After a mole or growth has been removed, a doctor can look at the tissue under the microscope to make sure that there are no more problem cells.
In most cases, your doctor will combine the pathology test results with an examination and other tests to make a diagnosis or plan treatments.
Sometimes tissue samples aren't easy to read. Different doctors may have different thoughts on what an area looks like under a microscope. It may help to have more than one doctor give an opinion.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
