Biopsy for Cancer Diagnosis: Types, Importance & What to Expect
Updated: Sep 4
Hearing the word “biopsy” after an abnormal scan or examination can naturally cause concern. Many people immediately associate a biopsy with cancer. But does being advised to have a biopsy mean that you have cancer? Not necessarily. A biopsy is a diagnostic procedure used to examine cells, tissues, or fluids and determine what is happening in the body. It can be used for several conditions, including infections, inflammation and other diseases, as well as cancer.
So, why is a biopsy so important when cancer is suspected? Let us understand some of the most common questions.
What Is a Biopsy?
A biopsy involves removing a small sample of tissue, cells, or fluid so that it can be examined by a medical pathologist. Doctors may recommend it when an examination, scan, or symptoms suggest that an area needs further evaluation.
Unlike imaging tests, which can show where an abnormality is located, a biopsy allows doctors to examine the actual cells. This can provide important information needed to confirm a diagnosis and plan treatment.
Does a Biopsy Always Mean Cancer?
No. Having a biopsy does not automatically mean you have cancer. Biopsies are also performed to investigate conditions such as inflammatory disorders, infections and other medical problems.
If an abnormal lump, growth, or area is detected, a biopsy can help determine whether the cells are normal, abnormal, benign, or cancerous. This makes it an important step when a definite diagnosis is required.
What Are the Different Types of Biopsy?
The type of biopsy depends largely on where the suspected abnormality is located and what needs to be examined. Some commonly used types include:
Needle biopsy
Incisional biopsy
Excisional biopsy
Bone marrow biopsy
Sentinel node biopsy
Punch or shave biopsy
Liquid biopsy in selected situations
Some biopsies can be performed using local anaesthesia, while others may require a different form of anaesthesia depending on the procedure and location.
Why Is a Biopsy Important for Cancer Diagnosis?
When cancer is suspected, a biopsy can provide evidence needed to confirm the diagnosis. The tissue sample is examined by a pathologist, who looks for abnormal changes in the cells.
The information obtained can help the cancer care team understand the disease and decide what further investigations or treatment may be appropriate. Depending on the situation, biopsy findings may also contribute to treatment planning.
Does a Biopsy Hurt?
This is one of the most common concerns. The level of discomfort depends on the type and location of the biopsy. Anaesthesia may be used to reduce or prevent pain during the procedure. Some people may experience mild pain or discomfort afterward.
How Long Does It Take to Get Biopsy Results?
There is no single waiting period for every biopsy. Results may be available within a few hours, several days, or sometimes longer, depending on the type of sample and the laboratory examination required. Your doctor will explain when you can expect the report and what the next steps may be.
Are Biopsies Safe?
Biopsies are generally considered safe, but complications can occur depending on the procedure. Possible complications include bleeding, infection, or scarring. Your doctor will explain the potential risks and any precautions you may need to take before and after the procedure.
What Should You Do After Receiving a Biopsy Recommendation?
Being advised to undergo a biopsy can be stressful, but it is important not to assume the result before the test is completed. If your doctor has recommended a biopsy because of a suspicious finding, timely evaluation can help establish the diagnosis and guide the next step.
