Overview
A tumour biopsy is a test that involves removing a small piece of tissue from a suspected tumour and examining it under a microscope. It is one of the most important things to do to make sure you don't have cancer. There are several ways to do a biopsy, depending on where the tumour is. These include needle biopsy, core biopsy, incisional biopsy, excisional biopsy, and image-guided biopsy with ultrasound or CT scan. A pathologist looks at the tissue that was collected to see if the cells are cancerous or not and to figure out what kind of cancer it is. Biopsy results help plan treatment and find out how far along the disease is and how aggressive it is.
Why It's Done
A tumour biopsy is done to make sure that cancer is present and to find out what kind it is. Imaging tests might show a mass, but only a biopsy can give a clear answer. It also helps find genetic markers or molecular features that affect decisions about targeted therapy. A correct diagnosis ensures that patients receive the best and most effective care.
What to Expect?
Before the biopsy, doctors review imaging tests such as CT, MRI, or ultrasound to determine the safest and most accurate approach. You might have blood tests to see how well your blood clots. Depending on the location and type of the procedure, it can be done with local anaesthesia, sedation, or general anaesthesia. A thin or core needle is used to take tissue samples from the tumour during a needle biopsy. Imaging is often used to make sure the needle goes in the right place. A small cut is made during a surgical biopsy to take out part or all of the tumour. The procedure can take anywhere from 15 minutes to more than an hour. After that, doctors monitor patients for pain, swelling, or bleeding. It's common to feel mild pain at the biopsy site, and it usually goes away on its own.
Recovery & Overlook
Most of the time, recovery is quick, especially after a needle biopsy. Most patients resume normal activities within a day. Biopsy results are usually ready in a few days, and they are very important for deciding what to do next with cancer treatment and care.
