Throat Cancer

Your throat is a tube that connects your nose to your neck. It's also called the pharynx, and it's made up of three parts: the nasopharynx (behind your nose), the oropharynx (behind your mouth, including your tonsils), and the laryngopharynx (lower part of the throat, also called the hypopharynx).

This tube also includes important parts like your esophagus (food tube), trachea (windpipe), larynx (voice box), tonsils, and epiglottis (a flap that prevents food from going down the wrong pipe).

Throat cancer is when cancer forms in your throat (pharynx) or voice box (larynx). Most often, this cancer starts in the flat cells lining the inside of these parts. Your voice box is located right below your throat, and it's also vulnerable to cancer. The voice box has cartilage and vocal cords that vibrate to create sound when you talk.

So, "throat cancer" is a broad term. It's used to describe cancer that begins in the throat (pharyngeal cancer) or the voice box (laryngeal cancer). While the types of cells involved are often similar, different names are used to pinpoint where the cancer started.

Here's a breakdown of the different types of throat cancer:

• Nasopharyngeal cancer: This starts in the nasopharynx, the part of your throat behind your nose.

• Oropharyngeal cancer: This begins in the oropharynx, the area behind your mouth, including your tonsils.

• Hypopharyngeal (or laryngopharyngeal) cancer: This starts in the lower part of your throat, just above your food pipe and windpipe.

• Glottic cancer: This forms in the vocal cords themselves.

• Supraglottic cancer: This starts in the upper part of the voice box, including the area around the epiglottis (a small flap of cartilage that prevents food from entering your windpipe).

• Subglottic cancer: This starts in the lower part of the voice box, below the vocal cords.

Your throat might have cancer if you notice any of these signs:

• Cough: A persistent cough, one that doesn't go away, could be a warning sign.
• Changes in your voice: If your voice is hoarse, sounds raspy, or you have trouble speaking clearly, this could be a problem.
• Trouble swallowing: If you're having difficulty swallowing food or liquids, it's something to check out.
• Ear pain: Pain in your ear, especially if it's accompanied by other symptoms, could be related to throat issues.
• A lump or sore that won't heal: A persistent lump or sore in your throat that doesn't get better needs attention.
• Sore throat: A sore throat that lasts for a long time, instead of just a few days, could be a sign of something more.
• Weight loss: Unexplained weight loss, especially if you've noticed it alongside other symptoms, is worth investigating.

If you experience any of these symptoms that last for a while, it's important to see a doctor. Many of these symptoms can also be caused by other, less serious things. Your doctor will likely look into those possibilities first before considering cancer. Don't ignore these signs; early detection is key for successful treatment.

If you notice any new, ongoing problems in your throat, make a doctor's appointment. Many throat issues that could be signs of cancer are also common with other illnesses. So your doctor will probably look into other, more usual causes first.

Throat cancer happens when the cells lining your throat change. These changes happen at a genetic level, meaning the instructions for how the cells grow and behave are altered. Normally, cells grow, do their job, and then die. But with throat cancer, the altered cells keep growing and dividing, even when they should stop. This buildup of abnormal cells can form a lump or growth called a tumor in the throat.

Exactly why these genetic changes occur isn't fully understood. However, doctors have found things that might make you more likely to get throat cancer.

HPV, or human papillomavirus, is a common infection spread through sexual contact. This virus can raise the chances of getting certain throat cancers. These cancers can affect areas like the soft roof of your mouth (soft palate), your tonsils, the back of your tongue, and the sides and back of your throat.

Several things can make you more likely to develop throat cancer:

• Smoking and chewing tobacco: Using tobacco products significantly increases your risk. The chemicals in tobacco damage cells and can lead to uncontrolled growth, which is how cancer starts.
• Heavy drinking: Regularly drinking too much alcohol can also increase your risk. Alcohol can damage cells and weaken your immune system, making it harder to fight off infections, including those that might lead to cancer.
• Certain viruses: HPV and another virus called Epstein-Barr virus are linked to throat cancer. These viruses can disrupt normal cell growth, potentially causing cancer.
• Poor diet: A diet low in fruits and vegetables may contribute to a higher risk of throat cancer. Fruits and vegetables are rich in vitamins and antioxidants that may help protect your cells from damage.
• Acid reflux (GERD): Gastroesophageal reflux disease (GERD) happens when stomach acid flows back up into your esophagus. This constant exposure to acid can damage the lining of your throat over time and increase your risk of cancer.
• Workplace exposure: Exposure to certain toxic substances in the workplace can also increase your risk. These substances can damage cells, leading to cancer.

It's important to remember that many factors can play a role in developing throat cancer, and this list is not exhaustive. If you have concerns about your risk, talking to a doctor is a good idea.

There's no sure way to prevent throat cancer, but you can lower your chances.

Here are some steps you can take:

• Quit smoking, or don't start. Smoking is a major risk factor for throat cancer. If you smoke, quitting is extremely important. It's tough, so don't be afraid to ask for help. Your doctor can explain different ways to quit, such as medication, nicotine patches, gum, or counseling. These methods can make quitting easier. If you don't smoke, don't start.

• Limit alcohol, or don't drink at all. Heavy alcohol use can also increase your risk of throat cancer. If you choose to drink, do so in moderation. For healthy adults, this means no more than one drink a day for women and no more than two drinks a day for men. A "drink" is typically a 12-ounce beer, a 5-ounce glass of wine, or a 1.5-ounce shot of liquor.

• Eat a healthy diet. Fruits and vegetables are packed with vitamins and antioxidants that might help lower your risk of throat cancer. Aim to eat a variety of colorful fruits and vegetables every day. This means different colored fruits and vegetables to get a wider range of vitamins and nutrients.

• Protect yourself from HPV. Some throat cancers are linked to HPV, a sexually transmitted infection. Having fewer sexual partners and using condoms every time you have sex can help lower your risk of HPV. Talk to your doctor about the HPV vaccine. This vaccine can help protect you from HPV and reduce your risk of throat cancer and other HPV-related cancers. It's important to get vaccinated according to your doctor's recommendations.

Diagnosing throat cancer often involves a few key steps:

1. Taking a Tissue Sample (Biopsy):

If a doctor suspects throat cancer, they might need to get a small piece of tissue for testing. This is often done during a procedure called an endoscopy or laryngoscopy. An endoscope is a thin, flexible tube with a light and camera at the end. It's inserted into your throat to let the doctor see inside. A laryngoscope is similar, but it focuses on your voice box (larynx).

During these procedures, if anything unusual is spotted, the doctor can use small instruments through the scope to remove a tiny tissue sample (a biopsy). This sample is sent to a lab.

In the lab, pathologists (doctors who specialize in examining tissue samples) look for cancer cells. They might also check for the presence of HPV (human papillomavirus). Knowing if HPV is present is important because it can affect the best treatment options for throat cancer.

2. Imaging Tests:

To understand how much of the throat or voice box is affected by the cancer, the doctor might use imaging tests like CT scans (computerized tomography), MRIs (magnetic resonance imaging), or PET scans (positron emission tomography). These tests create detailed pictures of the inside of your body, helping to see if the cancer has spread beyond the initial area.

3. Staging the Cancer:

Once throat cancer is diagnosed, the doctor needs to determine how far it has spread. This is called staging. Staging helps decide the best treatment plan.

The stage of throat cancer is described using Roman numerals (I through IV). Each stage has different criteria depending on the specific type of throat cancer. Generally, stage I means the cancer is small and contained in one area. Later stages (II, III, and IV) show more extensive spread, with stage IV being the most advanced. Understanding the stage is crucial for choosing the best course of action.

Treating Throat Cancer: A Guide for Patients

Throat cancer treatment depends on several factors. These include where the cancer is located, how far it has spread (the stage), the type of cells involved, whether the cancer is linked to HPV (human papillomavirus), your overall health, and your personal preferences. You and your doctor should discuss the pros and cons of each treatment option to choose the best approach for you.

Treatment Options:

• Radiation Therapy: This uses powerful beams (like X-rays or protons) to destroy cancer cells. There are two main types:

  • External beam radiation: High-energy beams are directed at the cancer from a machine outside the body.
  • Brachytherapy: Small radioactive sources (seeds or wires) are placed directly near the cancer. This is often used for smaller cancers that haven't spread. For larger cancers, radiation therapy may be combined with chemotherapy or surgery to shrink the tumor before surgery. In advanced cases, radiation therapy might be used to ease symptoms and make you more comfortable.

• Surgery: The type of surgery depends on the location and stage of the cancer.

  • Small cancers: Surgery might be the only treatment needed, or it may be used to remove the cancer from the surface of the throat or vocal cords using an endoscope. An endoscope is a thin, flexible tube with a light and camera, allowing doctors to see and remove very early throat cancers. A laser can also be used to vaporize small cancers, which is a less invasive way of removing cancer.
  • Larger cancers: Surgery might involve removing part or all of the voice box (larynx). If the entire larynx is removed (laryngectomy), you might need a breathing tube (tracheostomy) and speech therapy to learn to talk without your voice box. Surgery may also involve removing part of the throat (pharyngectomy). Surgeons can often reconstruct the throat to help you swallow normally after surgery.
  • Lymph node removal (neck dissection): If cancer has spread to the lymph nodes in your neck, your doctor might remove some or all of these nodes to see if they contain cancer cells.

• Chemotherapy: This uses drugs to kill cancer cells. It's often used with radiation therapy for throat cancer. Chemotherapy can make cancer cells more sensitive to radiation, but it also increases side effects. Be sure to discuss potential side effects with your doctor.

• Targeted Drug Therapy: These drugs target specific weaknesses in cancer cells to stop their growth. Cetuximab (Erbitux) is one example of a targeted therapy approved for some throat cancers. These drugs might be used alone or with other treatments.

• Immunotherapy: This uses your body's immune system to fight cancer. Sometimes, cancer cells hide from your immune system. Immunotherapy can interfere with this process, helping your immune system attack the cancer. Immunotherapy is often used for advanced throat cancers that haven't responded to other treatments.

Rehabilitation:

After treatment, you may need help regaining swallowing, eating, and speaking abilities. This might involve working with specialists to manage any surgical openings (stoma), eating difficulties, swallowing difficulties, neck stiffness, or speech problems.

Supportive (Palliative) Care:

Palliative care focuses on easing pain and other symptoms of serious illnesses. It can be used alongside other treatments to improve your quality of life. A team of doctors, nurses, and other specialists provide this care.
