There is a common fear that undergoing a biopsy might cause cancer to spread. While understandable, this concern is largely a myth. In modern oncology, biopsies are a vital diagnostic tool that helps doctors accurately determine the nature of suspicious growths.
According to Dr. Sandeep Nayak, an experienced surgical oncologist in India, “The risk of cancer spreading due to a biopsy is extremely rare and far outweighed by the benefits of early and accurate diagnosis.” Dr. Nayak is the founder of MACS Clinic, a center for advanced cancer treatment in Bangalore.
Extensive research supports the safety of biopsies, demonstrating no significant increase in cancer spread due to the procedure. Techniques such as needle biopsies and sentinel lymph node biopsies are carefully designed to minimize any disruption to surrounding tissue, making them crucial in the diagnosis and management of cancer.
Biopsies are not just routine procedures—they are key to personalized cancer treatment plans, ensuring patients receive the most effective care possible.
Can biopsy spread cancer? Let’s explore the process and why it’s safe…
How does a biopsy work?
A biopsy is a medical procedure where a small sample of tissue is taken from the body to examine under a microscope. The goal is to determine whether the cells are cancerous or benign. There are several types of biopsies, and the method used depends on the location of the suspected tumor, the size, and the patient’s overall health.
Needle biopsy: This is the most common form, where a thin, hollow needle is inserted into the suspicious area to remove a small sample of tissue. There are two main types:
- Fine-needle aspiration (FNA): This involves using a very thin needle to collect fluid or cells.
- Core needle biopsy: A larger needle is used to remove a small core of tissue, providing more detailed information about the tissue’s structure.
Surgical biopsy: In cases where needle biopsies are inconclusive or difficult to perform, a surgeon may remove part or all of a suspicious lump during a minor operation.
- Incisional biopsy: Only a portion of the tumor is removed for examination.
- Excisional biopsy: The entire suspicious area or lump is removed, which provides the most comprehensive sample for analysis.
Sentinel lymph node biopsy: In certain cancers, like breast cancer or melanoma, doctors may perform this procedure to determine if the cancer has spread to nearby lymph nodes. A small amount of dye or radioactive substance is injected to identify the sentinel lymph node, which is then removed and tested.
Once the tissue is collected, a pathologist examines it under a microscope to detect any abnormal or cancerous cells. This process provides essential insights into the type and stage of cancer, helping doctors tailor treatment plans accordingly.
The biopsy itself is usually a quick procedure, often done on an outpatient basis, with minimal discomfort and a fast recovery time.
The myth of cancer spread through biopsy
The notion that a biopsy could cause cancer to spread is a common misconception that has circulated for years. This myth often stems from the understandable fear of cancer patients and their families about the procedures used in diagnosis. Some worry that the process of extracting a tissue sample could somehow trigger the cancer cells to migrate to other parts of the body. However, this belief is not supported by scientific evidence.
Biopsies, in their various forms—whether needle, core, or surgical—are designed to be as precise and minimally invasive as possible. They are performed using specialized techniques that focus on removing only a small sample of tissue from a specific area.
The intent is to gather enough information for accurate diagnosis without disturbing the surrounding tissues or causing additional harm. The procedures are conducted under strict aseptic conditions to avoid any risk of infection or complications.

Scientific evidence against the myth
Extensive scientific research has debunked the myth that biopsies cause cancer to spread. Numerous studies have investigated the relationship between biopsy procedures and cancer progression, consistently finding no significant evidence that biopsies contribute to metastasis.
For instance, a study published in the Journal of Clinical Oncology reviewed various types of biopsies and confirmed that the risk of cancer spread from these procedures is negligible. A comprehensive review in The Lancet Oncology focused on breast cancer patients and found no increased incidence of metastasis linked to biopsy procedures. Additionally, research featured in Cancer Research concluded that biopsies do not contribute to tumor progression or spread.
Advancements in biopsy techniques have further minimized potential risks. Techniques such as image-guided biopsies and minimally invasive methods are designed to be as precise as possible, reducing the chance of any accidental impact on cancer spread.

Why biopsies are essential?
Biopsies are a cornerstone of modern medicine and play a crucial role in diagnosing and managing cancer. Here’s why they are so essential:
- Accurate diagnosis: Biopsies provide definitive information about whether a suspicious growth is cancerous. By examining the tissue sample under a microscope, pathologists can determine the presence, type, and grade of cancer. This accuracy is vital for planning the most effective treatment strategy.
- Tailored treatment plans: Knowing the exact type and stage of cancer allows doctors to create personalized treatment plans. For instance, the results of a biopsy can help determine whether surgery, chemotherapy, radiation, or a combination of treatments will be most effective.
- Monitoring disease progression: Biopsies can be used to monitor how well a treatment is working. By comparing tissue samples taken before and after treatment, doctors can assess whether the cancer is responding to therapy or if adjustments are needed.
- Assessing prognosis: The detailed information obtained from a biopsy can help predict the likely course of the disease and patient outcomes. This information is crucial for making informed decisions about treatment and care.
- Identifying genetic mutations: In some cases, biopsies can help identify specific geneticmutations within cancer cells. This information can be used to target treatments more precisely and is particularly important in personalized medicine.
Reducing uncertainty: A biopsy helps eliminate uncertainty and provides clarity about the nature of a suspicious area. This can alleviate anxiety for patients and enable timely intervention.

Safety measures in biopsies
Biopsies are generally safe procedures, but several measures are in place to ensure patient safety and minimize risks:
Sterilization: All instruments used in a biopsy are thoroughly sterilized to prevent infection. This includes needles, surgical tools, and imaging equipment. Many are single use instruments.
Precision techniques: Advanced imaging techniques, such as ultrasound or CT scans, are used to guide the biopsy needle precisely to the target area. This minimizes disruption to surrounding tissues.
Local anesthesia: To minimize discomfort, local anesthesia is applied to numb the biopsy site. This ensures the procedure is as painless as possible.
Minimally invasive methods: Many biopsies are performed using minimally invasive techniques, such as needle biopsies or endoscopic procedures, which involve smaller incisions and reduce recovery time.
Post-procedure care: After the biopsy, patients are given specific instructions for care, including how to manage any discomfort and signs of potential complications.
Experienced personnel: Biopsies are performed by skilled healthcare professionals who are trained to handle potential complications and ensure the procedure is conducted safely.
Informed consent: Patients are fully informed about the biopsy procedure, including its risks and benefits, before giving their consent. This ensures they are aware and comfortable with the process.
Conclusion
Biopsies are essential for accurate cancer diagnosis and treatment, performed with high precision and minimal risk. Understanding their role can ease concerns and lead to better-informed decisions. If you have any doubts regarding biopsies, talk to your oncologist to get clear, personalized answers.
