Histopathologists examine biopsies tissue or cells removed from patients in the clinic or during an operation. The histopathologist examines tissue biopsies with the naked eye to look for any visible abnormalities and to select pieces to examine in more detail under the microscope.
These small pieces are treated with chemicals so that very thin slices can be cut. The slices are stained to show different parts of the cells and examined under a microscope to see whether the tissue is abnormal. If it is, the aim is to identify the nature of the problem.
This often means that a definite diagnosis is made. They also examine cells in bodily fluids cytopathology such as urine, and also in large specimens, for example from surgery for bowel or breast cancer. Complications include the possibility of bleeding, missing the site of the suspect tissue, which can lead to a false negative result, and not collecting enough material, so that the biopsy needs repeating. One study into the outcomes of biopsies used in clinical trials found that that 5.
A study of breast biopsies has suggested that cancer cells may break away from a lump, spreading the disease to other areas. Other research, into biopsies for pancreatic cancer , meanwhile, concludes that endoscopic ultrasound-guided fine needle aspiration does not increase the risk of mortality. Whatever the risk, a biopsy can provide an early diagnosis of cancer and other diseases, and in many cases, early detection is key to increasing survival rates.

Analysis and results. Share on Pinterest During an excisional biopsy, the surgeon may remove a suspicious lump. What to expect. Using imaging guidance, the doctor will insert the needle through the skin, advance it to the site of the nodule , and remove samples of tissue. They may need to collect several specimens for complete analysis. Once the biopsy is complete, the doctor will apply pressure to stop any bleeding and cover the opening in the skin with a dressing.
No sutures are needed. You may be taken to an observation area for several hours. The doctor may use X-ray s or other imaging tests to monitor for complications. For stereotactic breast biopsies, you may lie face down or sit up on a moveable exam table and the affected breast or breasts will be positioned into openings in the table.
In a fine needle aspiration, a fine gauge needle and a syringe withdraw fluid or clusters of cells. In a core needle biopsy , the automated mechanism is activated, moving the needle forward and filling the needle trough, or shallow receptacle, with 'cores' of breast tissue. The outer sheath instantly moves forward to cut the tissue and keep it in the trough. This process may be repeated several times. In some breast biopsies, the tissue is removed with a vacuum-assisted device VAD. Vacuum pressure is used to pull tissue from the breast through the needle into the sampling chamber.
Without withdrawing and reinserting the needle, it rotates positions and collects additional samples. Typically, several samples of tissue are collected from around the lesion. After this sampling, the needle will be removed. If a surgical biopsy is being performed, a wire may be inserted into the suspicious area as a guide for the surgeon. Once the biopsy is complete, pressure will be applied to stop any bleeding, and the skin will be covered with a dressing or bandage.
Depending on the type of biopsy performed, you may be able to return home immediately after the procedure. This procedure is usually completed within one hour. You may be required to stay in an area for observation for several hours after the biopsy depending on the type of biopsy performed.
In a needle biopsy, you will feel a small sharp pinch at the site of the biopsy. In an open or closed biopsy that requires surgery, you will be given anesthesia to help with the pain. When you receive the local anesthetic to numb the skin, you will feel a slight pin prick from the needle.
You may feel some pressure when the biopsy needle is inserted. The area will become numb within a short time. You may receive a mild sedative prior to the biopsy.
If needed, you may receive sedation or relaxation medication intravenously during the procedure. You may feel sore at the area of the biopsy for a few days.
Your doctor can prescribe pain relief medication if you have significant pain from the biopsy. Aftercare instructions vary. However, you generally may remove your bandage one day after the procedure, and you may bathe or shower as normal.
After the tissue is collected, it is sent to a laboratory for analysis. A pathologist will examine the biopsy tissue under a microscope. A full report from the pathologist will be sent to your doctor in a few days. If you underwent a breast biopsy, it is likely the radiologist will discuss your results with you. This visit may include a physical check-up, imaging exam s , and blood tests. During your follow-up visit, tell your doctor if you have noticed any side effects or changes.
Generally a biopsy procedure is safe and causes minimal injury. Complications that may result from biopsies include:. In some cases, the amount of tissue obtained from a needle biopsy may not be sufficient and the biopsy may have to be repeated. This may be particularly true with trying to make a diagnosis of lymphoma.
Rarely, less invasive breast biopsy procedures may be unable to detect some lesions or determine the extent of disease present. If the diagnosis remains uncertain after a technically successful procedure, surgical biopsy will usually be necessary.
Any imaging-guided procedure will not be able to be used unless the area of abnormality can be seen. Some lesions, such as clustered calcifications on mammography are not as clearly shown with ultrasound as they are with mammography. Therefore, stereotactic biopsy is usually used in breast imaging to biopsy calcifications. Fluoroscopy sometimes will not be able to locate chest nodules, and CT will be used for guidance.
Your radiologist will use the image guidance best suited to biopsy the area in question. Please type your comment or suggestion into the text box below. Note: we are unable to answer specific questions or offer individual medical advice or opinions. Some imaging tests and treatments have special pediatric considerations. The different types of needle biopsies include the following:. If you have a rash or lesion on your skin which is suspicious for a certain condition, does not respond to therapy prescribed by your doctor, or the cause of which is unknown, your doctor may perform or order a biopsy of the involved area of skin.
Sometimes a patient may have an area of concern that cannot be safely or effectively reached using the methods described above or the results of other biopsy specimens have been negative. An example would be a tumor in the abdomen near the aorta.
In this case, a surgeon may need to get a specimen using a laparoscope or by making a traditional incision. Any medical procedure that involves breaking the skin carries the risk of infection or bleeding. However, as the incision is small, especially in needle biopsies, the risk is much lower. Biopsies may require some preparation on the part of the patient such as bowel prep, clear liquid diet, or nothing by mouth.
Your doctor will instruct you on what to do before the procedure. As always before a medical procedure, tell your doctor what medications and supplements you take. You may need to stop taking certain drugs before a biopsy, such as aspirin or nonsteroidal anti-inflammatory medications.
After the tissue sample is taken, your doctors will need to analyze it. In some cases, this analysis can be done at the time of procedure. More often, however, the sample will need to be sent to a laboratory for testing. The results can take anywhere from a few days to a few weeks. Once the results arrive, your doctor may call you to share the results, or ask you to come in for a follow-up appointment to discuss the next steps.
