If a biopsy is not possible, the doctor may suggest other tests that will help make a diagnosis. During a physical examination, the doctor feels for any lumps on the neck, lips, gums, and cheeks.
The doctor will also inspect the nose, mouth, throat, and tongue for abnormalities, often using a light and a mirror for a clearer view. An endoscopy allows the doctor to see inside the body with a thin, lighted, flexible tube called an endoscope.
The person may be sedated as the tube is gently inserted through the nose into the throat and down the esophagus to examine inside the head and neck. Sedation is giving a person medication to become more relaxed, calm, or sleepy.
A biopsy is the removal of a small amount of tissue for examination under a microscope. A pathologist is a doctor who specializes in interpreting laboratory tests and evaluating cells, tissues, and organs to diagnose disease.
A common type of biopsy is called a fine needle aspiration. During this procedure, cells are collected using a thin needle inserted directly into the tumor or lymph node.
A CT scan takes pictures of the inside of the body using x -rays taken from different angles. A computer combines these pictures into a detailed, 3-dimensional image that shows any abnormalities or tumors.
Sometimes, a special dye called a contrast medium is given before the scan to provide better detail on the image. This dye can be injected into a patient’s vein or given as a pill or liquid to swallow.

Healthy bone appears lighter to the camera, and areas of injury, such as those caused by cancer, stand out on the image. A PET scan is a way to create pictures of organs and tissues inside the body.
A small amount of a radioactive sugar substance is injected into the patient’s body. A scanner then detects this substance to produce images of the inside of the body.
The tissue obtained at the time of a biopsy is then reviewed by a pathologist who can help identify whether the mass is consistent with cancer. However, a cat scan (ct), MRI or ultrasound study may be more likely to detect a cancer in the neck.
A thorough and accurate cancer diagnosis is the first step in developing a head and neck cancer treatment plan. Your multidisciplinary team of cancer experts will use a range of tests and tools designed for diagnosing head and neck cancer, evaluating the disease and planning your individualized treatment.
During an indirect laryngoscopy and laryngoscopy, we place small mirrors at the back of your mouth to clearly examine your throat, the base of your tongue and part of your larynx. An endoscopy is minimally invasive, usually takes less time in the operating room and requires a smaller incision than traditional surgery, which helps to reduce blood loss.
A sample of tissue or cells is required for a biopsy, which must be conducted before treatment may begin. If the tumor is deeper inside the mouth or throat, the biopsy may need to be done in an operating room, with general anesthesia administered to prevent any pain.
These tests may show irregularities in the larynx, pharynx, mouth and surrounding areas, and is often used to detect small, early head and neck tumors. Computed tomography (CT) scan : A CT scan may provide information about the size, shape and position of the tumor, and may help identify enlarged lymph nodes to determine whether they contain cancer cells.
Diagnostic X -rays and other radio diagnostic devices are the largest man-made sources of radiation. The importance of this new study lies in the fact that there are no reliable data proving that radiation doses used in diagnostic X -rays do indeed contribute to the development of cancer.
The most recent previous study was conducted in 1981 and found that X -rays probably accounted for 0.5% of cancers in the United States. Fear of the risk arises because the number of CT exams done in recent years has increased steadily in comparison to conventional radiology.
They used the survivor data because it was the only time in history in which a large population was exposed to ionizing radiation. These researchers compiled their data on the incidence of cancers from tumor registers in the UK and 14 other countries.
In plain English this means that X -rays have been the cause of more than 5,600 cancer cases in the United States. To conclude, X -rays (and CTs) should be prescribed by doctors when they are absolutely necessary otherwise resorting to safer methods of investigation (e.g. ultrasonography, MRI) is always better.

To help ease symptoms caused by advanced cancers Radiation to the head and neck area can cause problems with tissue healing after dental work.
For this reason, your doctor may suggest you have a full dental exam before starting radiation. If you have dental problems, the doctor will want you to have an exam as soon as possible before radiation starts.
That means you get it at a hospital or a clinic, but you go home the same day. Computers and CT or MRI scans are used to match the radiation beams to the tumor’s shape from different angles.
This means fewer side effects for healthy tissue. It uses a computer to focus the radiation’s direction and strength more precisely on the tumor.
With this method, radioactive materials are placed inside or near the tumor. The radiation travels a short distance for a certain amount of time to kill cancer cells.
These sores may make it hard to eat because it’s painful to chew and swallow. Sores often go away a few days to a few weeks after radiation ends.
Radiation side effects can be more severe when you have it along with chemotherapy. In rare cases, radiation may lead to a breakdown of cartilage in the voice box (larynx).
If you have dry mouth after radiation, be careful with your oral and dental health. Dry mouth can cause problems with tooth decay.
