About Laryngeal (Larynx) Cancer
Laryngeal cancer occurs when malignant cells grow in the larynx. The exact cause of laryngeal cancer is not known, but certain risk factors can increase a person's chances of developing it.
Non-modifiable risk factors of laryngeal cancer cannot be changed or controlled. These include:
- Age: As people get older, their risk of developing this type of cancer increases.
- Certain genetic diseases: Rare genetic diseases can increase a person's susceptibility to laryngeal cancer.
Modifiable risk factors of laryngeal cancer can be influenced or changed. These include:
- Tobacco use, including smoking cigarettes and using other tobacco products, is a significant risk factor for laryngeal cancer. Quitting smoking can help reduce the risk, although it may remain higher for some time after quitting.
- Moderate to heavy alcohol consumption is also a major risk factor for laryngeal cancer. Limiting alcohol intake or avoiding it altogether can help lower the risk.
- Workplace exposure to certain carcinogens (substances that can cause cancer) is another modifiable risk factor for laryngeal cancer. This includes exposure to substances like asbestos, paint, gasoline fumes, and certain industrial solvents or chemicals like formaldehyde.
- Dietary choices: Eating a diet low in green, leafy vegetables and high in fats and salt-preserved meats may increase the risk of laryngeal cancer.
The most common early symptoms of laryngeal cancer, which affects the voice box, include:
- Hoarse voice without another cause, such as a cold or the flu
- Persistent sore throat
- Painful swallowing
- Trouble swallowing
It's important to note that many of these symptoms can also be caused by other conditions. However, if these symptoms persist for more than a few weeks, it's a good idea to contact your doctor.
As laryngeal cancer progresses or reaches a higher severity, additional symptoms may occur. These can include:
- Unintentional weight loss
- Shortness of breath
- Difficulty breathing
- A lump or noticeable mass in the neck
In later stages, laryngeal cancer can also spread to other organs, such as the lungs. This can cause symptoms like persistent coughing, coughing up blood, chest pain, decreased appetite, and further weight loss.
It's important to remember that these symptoms can be caused by other conditions as well. If you experience voice changes that don't improve within two weeks or develop other concerning symptoms like throat pain, trouble breathing, trouble swallowing, or an unexplained lump in your throat, it is recommended to contact your healthcare professional for further evaluation and guidance.
If you have any concerns about laryngeal cancer or any persistent symptoms, it's always best to consult with a doctor for a proper diagnosis and necessary treatments.
To diagnose laryngeal cancer, doctors commonly perform several examinations, tests, and procedures. These include:
- Physical examination: During a physical exam, the healthcare provider will check for physical signs of laryngeal cancer, such as lumps in the neck, swelling, persistent throat pain, voice changes (like hoarseness), or difficulty swallowing. They may also look for signs of airway obstruction or other abnormalities in the throat.
- Direct laryngoscopy: This is a common test used to diagnose laryngeal cancer. It involves placing a tube with a camera into the throat to examine the larynx and take a biopsy (tissue sample) if necessary.
- Radiology tests: Doctors may use radiology tests to help stage the diagnosis and determine the severity of laryngeal cancer. These tests include:
- Computed tomography (CT) scan: This imaging test uses X-rays and computer technology to create detailed cross-sectional images of the head and neck area.
- Magnetic resonance imaging (MRI): This imaging test uses powerful magnets and radio waves to create detailed images of the head and neck area.
- Positron emission tomography (PET) scan: This imaging test involves injecting a small amount of radioactive material into the body to highlight areas with cancerous changes.
Additional examinations, tests, and procedures may be performed to determine the stage or severity of laryngeal cancer. These may include:
- Laryngoscopy: This test uses a thin, flexible tube with a light and camera at its tip to examine the larynx in detail. It helps doctors assess the extent of cancer involvement.
- Panendoscopy: This procedure examines not only the larynx but also the esophagus (food pipe) and windpipe. It provides a comprehensive view of these areas for further evaluation.
- Biopsy: A biopsy involves removing a small tissue sample from the larynx for examination under a microscope. It helps confirm the presence of cancer cells and determine their characteristics.
It's important to note that if you experience any symptoms related to laryngeal cancer, such as a persistent hoarse voice, sore throat, difficulty swallowing, coughing up blood, ear pain, or a lump in the neck, it's crucial to visit your primary care doctor for further evaluation. They may refer you to an otolaryngologist or an ear, nose, and throat specialist who can perform these examinations, tests, and procedures to diagnose and stage laryngeal cancer.
The main goals of treatment for laryngeal cancer are:
- Local control of the disease: The primary aim is to eliminate or control the cancer within the larynx and surrounding tissues. This helps prevent the cancer from spreading to other parts of the body.
- Survival: Another important goal is to improve long-term survival rates for individuals with laryngeal cancer. Treatment aims to remove or control the cancer cells to increase the chances of survival.
- Preservation of laryngeal anatomy and functions: Maintaining the function of the larynx is crucial for speech, swallowing, and proper airway function. Preserving these functions can significantly improve a person's quality of life after treatment.
To achieve these goals, various treatment options are available, including:
- Surgery: Surgical procedures can involve removing part or all of the larynx, depending on the extent and location of the cancer. In some cases, reconstruction techniques using tissue from other parts of the body may be necessary to restore continuity in the upper digestive tract.
- Radiation therapy: This treatment option uses high-energy radiation beams to target and destroy cancer cells in the larynx. It can be used as a primary treatment or in combination with other therapies.
- Chemotherapy: Medications are used to kill cancer cells throughout the body. Chemotherapy is often used in combination with radiation therapy for more advanced cases of laryngeal cancer.
- Targeted molecular therapy: This newer form of treatment uses medications that specifically target certain molecules or pathways involved in cancer growth. These drugs can help slow down or stop the growth of cancer cells.
In addition to these medical treatments, there are also health behavior changes that can support treatment goals:
- Smoking cessation: Quitting smoking is essential for individuals with laryngeal cancer as smoking is a major risk factor for this type of cancer. Quitting smoking can improve treatment outcomes and reduce the risk of recurrence.
- Alcohol moderation: Excessive alcohol consumption is another risk factor for laryngeal cancer. Limiting alcohol intake or abstaining from alcohol can support treatment effectiveness and reduce the risk of complications.
It's important to note that treatment plans for laryngeal cancer are individualized based on factors such as the stage of cancer, overall health, and patient preferences. A multidisciplinary team, including oncologists, surgeons, and other healthcare professionals, will work together to determine the most appropriate treatment approach for each individual case.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
Laryngeal cancer is a type of cancer that affects the larynx, or voice box. It is one of the most common tumors in the head and neck region, accounting for about 25% of malignancies in that area and 2% of all malignancies. The larynx plays a crucial role in swallowing, breathing, and phonation (producing sound).
The natural progression of laryngeal cancer can vary depending on the stage at which it is diagnosed. In the early stages, laryngeal cancer has a high cure rate. However, if left untreated or if it progresses to advanced stages, it can lead to complications and a decrease in quality of life.
Complications commonly associated with laryngeal cancer include:
- Impairment of functions: Laryngeal cancer can affect the normal functioning of the larynx, leading to difficulties in swallowing, breathing, and speaking. These impairments can significantly impact a person's quality of life.
- Spread to nearby lymph nodes: If laryngeal cancer spreads, it often reaches nearby lymph nodes in the neck. This can further complicate the treatment and increase the risk of recurrence.
- Spread to other parts of the body: In advanced stages, laryngeal cancer cells can spread to other parts of the body such as the back of the tongue, other sections of the throat and neck, lungs, and other organs. This is known as metastasis and can further worsen prognosis.
In conclusion, laryngeal cancer can have varying natural progression depending on its stage at diagnosis. Complications commonly associated with this type of cancer include impairments in swallowing, breathing, and speaking, as well as spread to nearby lymph nodes and other parts of the body. Treatment options aim to cure the disease, slow its progression, or reduce complications through approaches such as surgery, radiation therapy, chemotherapy, and targeted therapy. It's important for individuals with laryngeal cancer to work closely with their healthcare team to determine the best course of treatment for their specific situation.
