Biopsy

If your doctor thinks you have cancer, he or she will probably ask you to have a test called a biopsy.

It’s normal to feel nervous before having a medical procedure. But biopsies are very important. They can rule out cancer or confirm the type and stage of cancer you have. An accurate diagnosis is key to getting you appropriate, potentially lifesaving treatments.

What is a Biopsy?

Biopsy is the medical term for removing tissue from your body, then studying it under a microscope. Other tests can find potential tumors. But only biopsies can distinguish between normal cells and cancerous cells.

There are many ways to take a tissue sample. Some biopsies can be performed quickly with minimal discomfort. Others are more invasive and require sedation. The most common biopsy procedures include:

  • Needle biopsies remove tissue through a small, hollow needle attached to a syringe. Your doctor may use CT, MRI or ultrasound imaging to guide the needle.
  • Skin biopsies collect skin cells. Some skin biopsies simply scrape the surface of your skin. Others require several layers of skin to be removed and stitched back together.
  • Endoscopic biopsies use flexible tubes (endoscopes) with tiny lights and cameras attached. They let your doctor see inside your body. Special tools passed through the endoscope collect tissue samples. Examples of endoscopic procedures include colonoscopy, bronchoscopy and sigmoidoscopy.
  • Surgical (open) biopsies are more invasive. Your doctor will surgically remove all or part of a known tumor for testing. An excisional biopsy removes the entire tumor. An incisional biopsy cuts out only a piece of tumor.

The type of biopsy you’ll need depends on several factors. These include where in the body your tumor may be located.

Your tissue sample will be studied by doctors called pathologists. If you have cancer, your results will likely show where your cancer started and how aggressive it is. Your tissue may also be tested to see if it contains gene mutations or special proteins to determine if certain treatments such as targeted therapy are appropriate for you.
