Biopsy is mainly associated with cancer and it helps doctors to detect abnormalities or any kind of diseases present in a human body. When a biopsy is done, a piece of tissue or a sample of cells is removed from body so that it can be analyzed in a laboratory. Based on the type of cancer there are various kinds of biopsies including Skin Biopsy, Bone Marrow Biopsy, Surgical Biopsy, Needle Biopsy and Endoscopic Biopsy.
A biopsy test gives doctors detailed information about diseases and helps the patient to take timely precautions. When a biopsy is done, a piece of tissue or a sample of cells is removed from body so that it can be analyzed in a laboratory. A pathologist observes the tissue sample under a microscope and then determines whether the tissue is cancerous or not. If you are experiencing certain signs and symptoms the causes of which remain undetected even after repeated testing, the only way to make a definitive diagnosis is to perform a biopsy. It would help to determine whether you have cancer or not. After an analysis of the reports, doctor may suggest a biopsy based on the symptoms and health conditions of the patient. If doctor suspects that it may have affected the bone marrow then it is highly advised to go for a bone marrow biopsy. In this procedure, a doctor obtains some bone marrow (a mass of spongy tissues produced inside some larger bones) from the back of hipbone using a fine needle. The pathological examination of bone marrow tissues reveals the kind of blood problems as blood cells are produced in red and yellow marrow.
Biopsies are done to identify cancer and many other health conditions. A doctor may recommend a biopsy whenever there is an important medical question that biopsy could answer. A biopsy is mainly done when :
The different types of biopsies are given below:
A skin biopsy is used to diagnose skin conditions especially if there is a rash or lesion on skin, which is suspicious for a certain condition. In this process, cells are removed from the surface of body with the help of a circular blade called “Punch” or with a razor blade, a scalpel etc.
This is mostly done by using local anesthesia. The specimen is sent for a skin biopsy to find out if there is a possibility of some infection, cancer, or inflammation of the skin structures or blood vessels. The clinical results of skin biopsy determine the stage or grade of cancer or other conditions.
Bone marrow biopsy is done if the doctor suspects that there are problems in blood cells. It helps in determining the type and extent of blood problem for both cancerous and noncancerous condition such as leukemia, lymphoma, anemia and multiple myelomas. This kind of biopsy can also detect if cancer cells have spread to other parts of bones. In this type of biopsy, bone marrow is easily accessed by using a long needle inserted into hipbone. Patients can feel a dull pain initially during this procedure therefore local anesthetic is injected to suppress pain.
Surgical biopsy is done in order to remove abnormal cells present in breast or a tumour in brain. Those cells, which are not easily accessible with the help of a needle, are obtained with surgical biopsy. An incision in made into the surface of skin to access the suspicious area of cells. Surgical biopsy uses local anesthetics to numb the area of the biopsy while some procedures require general anesthetics to make patients unconscious during the procedure.
In this procedure, an endoscope is inserted with the help of a tube into a patient’s body to observe the condition of the affected and suspicious cells. The endoscope has a tiny light and a camera, which allows the doctor to get better images while collecting the sample. Endoscopic biopsies are widely used in form of cystoscopy to collect tissue from inside bladder, lungs (bronchoscopy) and colon (colonoscopy). The endoscope can be inserted through any opening in the body, including nose, mouth, rectum or urethra. Patients can get uncomfortable, swelling or bloating, gas, or a sore throat, which eventually gets better with time.
A needle biopsy is used to extract cells from a tumour that a doctor can easily feel through pressing that part of the skin. Under this process, a doctor uses a needle and extracts fluid or cells from the affected part. This procedure is commonly used for getting suspicious breast lumps and enlarged lymph nodes. A doctor usually derives cells from the inner areas under the skin that cannot be felt from outside by combining it with an imaging procedure, such as X-ray.
When doctor collects a sample of affected tissues by using a needle or surgical procedure, then that sample is sent to a laboratory for clinical analysis. A pathologist treats the sample chemically or freezes and cuts them into thin slices, which are stained and observed under a microscope. Proper staining of the slices enhances contrast and helps in getting suitable results as revealed by the tissues.
A complete and accurate pathology report is important for diagnosis and deciding on the best treatment plan. Biopsies are also used to diagnose other conditions and see how far a disease has progressed. Here is a quick checklist of some important reasons that make biopsy as an indispensable diagnostic procedure for cancer and other health problems :-
1. To detect and differentiate between cancerous and non-cancerous cells
Be it an X-ray, CT scan, MRI, imaging test cannot give you precise result whether the cells are cancerous or not. It is only through biopsy and close observation of the specimen that a doctor can conclude whether it is a cancer or some other abnormalities.
2. Helps check the spread of cancer
The results of a biopsy not only tell that it is cancer but also helps doctor determine the grade and stage of cancer. The grading of cancer on the scale of 1 to 4 simply tells the aggressiveness or stage of cancer that helps in determining the right clinical procedures after the diagnosis.
3. Helps doctors plan the best treatment
After a biopsy tests and diagnosis, doctor can easily determine the best treatment that needs to be given to patients for quick recovery. In other words, one can say that biopsy test result helps doctors determine whether the cells need further examination for more conclusive results that helps a patient recover from the disease.
Biopsy preparation may include bowel preparation, getting on clear liquid diet, or in some cases you will need to remove your clothing and wear a gown.You will be given clear instructions from the doctor as to what you need to do before the procedure.
A doctor may get the results of biopsy within few hours or if the tissue sample is sent to a laboratory then it may take few days to few weeks too. After going through the results, the doctor will inform you the type and grade of cancer you are suffering from and the best kind of treatment available.
A biopsy can provide early diagnosis of cancer and detect the presence of any other abnormalities in body. If you are looking for a specialist for Biopsy test or cancer related problems you can call us at+91-8929020600

PET Scan is an imaging test which uses radioactive tracer to look inside human body including oxygen use and metabolism at cellular level. This test can detect cancer, brain tumor or heart disease.
Caused by genetic mutation of the brain cells or low-grade glial tumor, brain cancer is not a condition that can always be prevented effectively but having thorough knowledge about the triggering factors, symptoms, and precautions can definitely impact your chances of developing it. Timely screening, eating healthy food and staying away from carcinogens can help in preventing brain cancer.
