Diagnosis of Laryngeal Cancer: Methods and Procedures
The diagnosis of laryngeal cancer involves a combination of methods to accurately detect the condition in its early stages. Doctors typically begin with a thorough physical examination and medical history review. To confirm the diagnosis, imaging tests like CT scans or MRIs may be performed, followed by a biopsy to examine tissue samples. Early detection is key for effective treatment, so understanding the diagnostic process is crucial for timely intervention.
What is the Diagnosis of Laryngeal Cancer?
If you have the above symptoms, your doctor might suggest you undergo some tests which includes:
To confirm laryngeal cancer, your doctor might need to examine the larynx with the help of an instrument called a laryngoscope. Your doctor can examine your larynx either by checking the reflection of your larynx in the mirror of the laryngoscope or by indirect laryngoscopy.
Alternatively, your doctor can insert a flexible fibre-optic laryngoscope into your throat to take a look at your larynx and other structures around it or a direct laryngoscope.
Direct rigid laryngoscopy is a complex procedure that allows your doctor to examine your larynx completely. During direct rigid laryngoscopy, your doctor will administer anaesthetic drugs through an intravenous or IV line. During this procedure, the doctor examines the throat for any tumor. Sometimes the doctor may collect biopsy samples too while performing direct rigid laryngoscopy.
To ascertain the presence of cancer cells in the larynx, your doctor may recommend that you undergo a biopsy (larynx biopsy). Generally, your doctor inserts a fine needle into the larynx to collect tissues for biopsy. The tissue collected from the larynx is analysed in the laboratory to determine the presence of cancer cells.
With the help of imaging tests, your doctor can visualise internal organs and their condition.
CT Scan: A CT scan helps your doctor determine the size of the tumor and its extent.
MRI scan: By performing an MRI scan, your doctor can determine the spread of cancer in the neck or other body parts.
Before starting the treatment, your doctor may suggest a few tests to determine the measure of different types of blood cells in the body. Sometimes, your doctor might suggest you undergo a Lung function test as well.
Frequently Asked Questions (FAQs):
Q1. What tests are used to diagnose laryngeal cancer?
A. The diagnosis typically involves a physical examination, imaging tests like CT or MRI scans, and a biopsy to examine tissue samples for cancer cells.
Q2. How is a biopsy performed for laryngeal cancer?
A. A biopsy is performed by removing a small tissue sample from the larynx, usually through an endoscope, to check for abnormal or cancerous cells.
Q3. How early can laryngeal cancer be detected?
A. Laryngeal cancer can often be detected early through imaging tests and biopsies if symptoms like persistent hoarseness or throat pain are reported to a doctor.
