Is a biopsy painful?

Understanding Pain During a Biopsy

A biopsy is a medical procedure in which a small sample of tissue or cells is taken from the body to be examined under a microscope to diagnose diseases or assess the extent of damage [3]. A biopsy is typically performed in a way designed to minimize pain as much as possible. In most cases, local anesthesia is used to numb the area from which the sample will be taken, meaning you may feel some pressure or mild discomfort, but not sharp pain [1]. For example, when performing a kidney biopsy, a healthcare professional cleans the area and injects a local anesthetic to numb it before inserting the biopsy needle [1]. Similarly, in a liver biopsy, the area where the biopsy needle will be inserted is numbed with a local anesthetic, and you may be given sedatives and pain relievers if necessary [2].

In some types of biopsies, such as an open surgical biopsy or a laparoscopic kidney biopsy, general anesthesia may be used, which means you will be completely asleep and will not feel any pain during the procedure [1].

Types of Biopsies and Their Impact on Pain Sensation

• Percutaneous Biopsy (Needle Biopsy): This is the most common type, where a thin needle is inserted through the skin to take a sample. A local anesthetic is used to numb the area, and you may feel pressure or a mild stinging sensation. For example, during a percutaneous kidney biopsy, the doctor may ask you to hold your breath for a moment, and you might hear a clicking sound from the needle, which is normal [1].
• Transjugular Biopsy: This method is typically used for patients at a higher risk of bleeding, such as a transjugular liver biopsy. A needle is inserted into a vein in the neck and guided to the target organ. A local anesthetic is used, and sedatives may be administered [2].
• Surgical Biopsy: These types involve making a small or large incision to obtain the sample. They are performed under general or local anesthesia, depending on the type and location of the surgery. For instance, a laparoscopic kidney biopsy requires general anesthesia [1].

What to Expect After a Biopsy?

After the biopsy, it is normal to feel some mild pain or discomfort at the biopsy site. This pain is usually mild and subsides within a few hours after the procedure [1], [2]. Your doctor may prescribe pain relievers or recommend over-the-counter pain medication to manage any discomfort [2]. In some cases, you may need to stay in the recovery room for several hours so your blood pressure, pulse, and urine can be monitored to ensure there is no internal bleeding [1].

It is important to follow your doctor's instructions after the biopsy, which may include avoiding strenuous activities and heavy lifting for a certain period, which may last up to a week or two, depending on the type of biopsy [1], [2]. You may also notice some changes, such as pink or cloudy urine for 24 to 48 hours after a kidney biopsy, which is normal [1].

When Should You Seek Immediate Medical Care?

Although most biopsies proceed without serious complications, there are some symptoms that require immediate medical attention. You should contact your doctor or go to the nearest emergency department if you experience any of the following symptoms after the biopsy:

• Severe or unexpected bleeding from the biopsy site.
• Worsening pain at the biopsy site that does not subside with pain relievers or persists for more than a few hours [1], [2].
• Redness, swelling, or other discharge from the biopsy site [1], [2].
• Fever [1], [2].
• Dizziness, fainting, or weakness [2].
• Difficulty urinating, frequent urge to urinate, a sense of urgency to go to the bathroom, or a burning sensation when urinating (especially after a kidney biopsy) [1].
• Dark-colored, brown urine, or urine containing blood clots (especially after a kidney biopsy) [1].
• Nausea or vomiting [2].
• Pain in the abdomen, shoulder, or chest [2].
• Breathing problems or shortness of breath [2].
• Rapid or racing heartbeat [2].
• Stools that contain blood or are black and tarry (especially after a liver biopsy) [2].
• Abdominal swelling or bloating [2].
