A biopsy (a sample of tissue taken from the part of your body where cancer
is suspected) is how cancer is diagnosed. Imaging tests, such as X-rays,
are helpful in detecting masses or areas of abnormality, but they can't
differentiate cancerous cells from noncancerous ones. A biopsy to collect
cells for closer examination is required to definitively diagnose most
types of cancer.
Our pathology labs use multiple techniques to test biopsied tissue to determine
whether it is cancer and, if so, of what specific type and sub-type. Accurate
diagnosis is vital to successful treatment of cancer.
At Torrance Memorial we use advanced techniques and modern imaging technology
to obtain biopsies in the least invasive fashion. We do everything we
can to help you stay comfortable during the procedure, and to ensure that
your recovery is quick and uneventful.
Types of Biopsies Used in Diagnosing Cancer
There are several different kinds of biopsies. Your doctor will choose
the type to use based on your condition and the area of your body that
needs closer review.
Bone Marrow Biopsy
Inside some of your larger bones—such as the hip or the femur in
your leg—blood cells are produced in a spongy material that is called marrow.
If your doctor suspects there are problems with your blood, you may undergo
a bone marrow biopsy. This test can single out both cancerous conditions,
such as leukemia or lymphoma, and noncancerous conditions, such as anemia
or an infection. A bone marrow test is also used to check if cancer cells
from another part of the body have spread to your bones.
The easiest and most efficient way to reach bone marrow is by inserting
a long needle into your hipbone. This may be done in a hospital or doctor’s
office. Though some people feel a dull pain during this procedure (because
the insides of your bones cannot be numbed), for many the only sensation
is from injection of the local anesthetic.
Needle biopsy is used to collect samples of tissues from the body. The
different types of needle biopsy include:
Core needle biopsy: These uses a medium-sized needle to extract a column of tissue, in the
same way that a core sample is taken from the earth
Fine needle biopsies: This uses a thin needle to remove cells for testing
Endobronchial ultrasound (EBUS) with biopsy: This advanced, image-guided biopsy technique combines ultrasound with
a bronchoscope for precision in obtaining a biopsy
Endoscopic ultrasound (EUS) with biopsy: This imaging technology that adds ultrasound to endoscopy to access the
lungs and nearby structures
Image guided biopsy: An imaging procedures—such as an ultrasound or a CT scan —
guides your doctor to target specific areas, such as the lung, liver,
or other organs
Vacuum-assisted biopsy: These use suction from a vacuum to collect cells
Electromagnetic Navigation Bronchoscopy (ENB), available at Torrance Memorial,
is a minimally invasive technology that allows full exploration of all
parts of the lungs. ENB is a useful technology for diagnosis and treatment
of cancerous lesions in the lungs, in a minimally invasive way, without
the need for complex surgery.

Endobronchial Ultrasound (EBUS)
An advanced, image-guided biopsy technique that combines ultrasound with
a bronchoscope, offers many advantages for accurate diagnosis and staging.
Benefits include improved visualization of the airways and surrounding
tissue, allowing precise localization
Endoscopic Ultrasound (EUS)
EUSis a type of imaging technology that adds ultrasound to endoscopy to
visualize and gain information about the lungs and surrounding organs
