In addition, the following tests may be used to diagnose head and neck cancer:. 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. Blood tests and urine tests may be done to help diagnose cancer. 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.
The examination has different names depending on the area of the body that is examined, such as laryngoscopy to view the larynx, pharyngoscopy to view the pharynx, or nasopharyngoscopy to view the nasopharynx. When these procedures are combined, they are sometimes referred to as a panendoscopy. A biopsy is the removal of a small amount of tissue for examination under a microscope. A pathologist then analyzes the sample s removed during the biopsy.
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. The cells are examined under a microscope for cancer cells, which is called a cytologic examination.
The biopsy may include testing to see whether the person has HPV. In some cases, whether a person has HPV can also be a factor in determining which treatments are likely to be most effective. Biomarker testing of the tumor. Your doctor may recommend running laboratory tests on a tumor sample to identify specific genes, proteins, and other factors unique to the tumor.
This may also be called molecular testing of the tumor. Results of these tests can help determine your treatment options. Products and services.

For example, people with leukemia often have an unusual number or type of white blood cells that show up on a blood test.
Your doctor may also recommend a lab test to check for genetic mutations, or changes, that increase your risk for certain cancers. Imaging tests can help doctors see inside your body and look for a tumor or areas where cancer is present. Some common types include:.
Sometimes, endoscopic exams can be used to find cancer. These procedures allow doctors to see inside your body with the help of an endoscope camera. Common types of endoscopies include colonoscopy , sigmoidoscopy, and cystoscopy.
Your doctor might perform a physical exam to check for lumps, enlarged organs, or other signs that could indicate you have cancer. You will need further testing if your physician thinks you might have cancer after a physical exam. Your doctor may suggest several other tests, depending on what kind of cancer is suspected. For instance, your physician might want you to take a pulmonary breathing test if he thinks you have lung cancer.
What Tests Will I Get? Liquid biopsies, which are performed via a simple blood test, offer a promising role in cancer detection.
But there are still some problems to work out. But scientists are hopeful that advances in technology could lead to a noninvasive cancer blood screening test in the near future.
These abnormalities to your DNA may be acquired caused by environmental factors or inherited passed down through your family. These tests help determine whether you have genetic mutations associated with a higher risk of developing specific cancers.
Advanced genomic testing : Cancerous cells are extracted from a biopsy sample and their DNA is sequenced in a lab to identify characteristics resembling known mutations. This helps your doctor determine treatment options. Genetic testing : Typically done with a blood test or mouthwash, a sample is taken to detect gene mutations that may contribute to increased cancer risk. Even after the validation of your diagnosis, our diagnostics program continues to play an important role throughout your cancer treatment.
Tests to determine the stage of your cancer help you and your doctor know how much cancer is present and help determine an appropriate treatment plan tailored to you, based on your diagnosis and personal goals.
Staging procedures may include imaging tests, endoscopy exams, lab tests and biopsies. Most cancers are given a stage of 0 to 4. The higher the stage number, the farther the cancer has spread. We understand that waiting for diagnostic test results can create a great deal of stress. To ease anxiety and help you begin your cancer treatment as soon as possible, we work to reduce wait times for appointments and test results.
In some cases, we offer telehealth appointments so that you can ask questions via a smartphone or computer. Make a difference in the fight against cancer by donating to cancer research.
