Overview
A biopsy is a test used to look more closely at cells or tissue from a specific part of the body. A healthcare professional may suggest it after finding a lump, a skin lesion, unusual bleeding, an abnormal imaging result, or changes in blood or organ function tests. The sample is sent to a laboratory, where a specialist examines it under a microscope and may do other tests on it.
Who Is Affected
People of any age may need a biopsy if there is a concerning change that needs a clearer diagnosis. Biopsies are commonly used for the skin, breast, cervix, bone marrow, liver, kidney, prostate, lung, thyroid, lymph nodes, and digestive tract. The reason for the biopsy and the way it is performed depend on the body part and the suspected condition.
Diagnosis and Tests
There are several types of biopsy, including needle biopsy, skin biopsy, endoscopic biopsy, bone marrow biopsy, and surgical biopsy. Imaging such as ultrasound, CT, MRI, or mammography may be used to guide the sample. Before the procedure, you may be asked about medicines, allergies, bleeding problems, pregnancy, or implanted devices. Results may take days or longer depending on the type of testing needed.
Treatment Categories
A biopsy itself is a test, not a treatment, but the results often guide what happens next. Depending on the findings, follow-up may include more imaging, repeat biopsy, monitoring, referral to a specialist, or treatment for infection, inflammation, autoimmune disease, or cancer. Some very small abnormal areas may be fully removed during the biopsy procedure.
Living With It
Many people feel anxious while waiting for biopsy results, and it can help to ask when and how the results will be shared. After the procedure, follow the care instructions for the biopsy site, including how to keep it clean and what activity limits apply. Contact your healthcare team if you are unsure whether bleeding, pain, swelling, or fever is expected.
When to Seek Medical Care
Seek medical advice if you have increasing redness, swelling, warmth, drainage, fever, or worsening pain after a biopsy. You should also contact your healthcare team if you have bleeding that does not stop as instructed, new numbness, trouble urinating after some pelvic procedures, or if you have not received results within the expected time. Ask for urgent advice if symptoms change quickly.
When It May Be an Emergency
Get urgent medical help right away if you have severe bleeding, trouble breathing, chest pain, fainting, severe allergic symptoms, or sudden severe swelling after a biopsy. These symptoms can happen after certain procedures, especially those involving the lung, deep organs, or sedation. Emergency care is also needed if you cannot wake normally after sedation or develop rapidly worsening symptoms.
Questions to Ask a Healthcare Professional
You may want to ask why the biopsy is needed, what type will be done, whether imaging or sedation will be used, and what risks apply to your situation. It can also help to ask how to prepare, whether to stop any medicines, how long recovery may take, and when results are expected. Ask who will explain the results and what the next steps could be based on different possible findings.
