Does a biopsy tell you what stage cancer is?
A biopsy often is needed to confirm a cancer diagnosis.
Biopsies might also be needed to find out if a lump felt on an exam or if something seen on an imaging test in another part of the body is really from the spread of cancer..
What happens when you have a biopsy?
A biopsy (taking a tissue sample) is one of the most commonly used medical tests. Tissue samples can be analyzed in order to find out, for instance, whether a suspicious lump is harmless or dangerous. The doctor removes a small sample of tissue and sends it to a laboratory to be examined under a microscope.
Can a biopsy cause cancer to spread?
Patients and even some physicians have long believed that a biopsy can cause some cancer cells to spread. “This study shows that physicians and patients should feel reassured that a biopsy is very safe,” Dr. Wallace said.
Is a biopsy painful?
A needle biopsy is less invasive than open and closed surgical biopsies, both of which involve a larger incision in the skin and local or general anesthesia. Generally, the procedure is not painful and the results are as accurate as when a tissue sample is removed surgically.
