সংজ্ঞা

Laryngeal cancer is a disease in which cancer cells grow in the larynx. The larynx is a tube-shaped organ inside the neck that lies between the throat and the windpipe. Its main function is to produce sound for speaking.

Cancer occurs when cells in the body—in this case laryngeal cells—divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant tumors, which can invade nearby tissues and can spread to other parts of the body. A benign tumor does not invade or spread.

কারণসমূহ

The cause of laryngeal cancer is not known.

ঝুঁকির কারণ

Factors that increase your chance of getting laryngeal cancer include:

  • Smoking —the most common high-risk behavior
  • Excessive use of alcohol
  • জাতি: কালো
  • বয়স: 55 বা তার বেশি
  • সেক্স পুরুষ
  • Occupational exposure to certain air pollutants such as wood dust, chemicals, and asbestos
  • Gastroesophageal reflux (GERD)—stomach acid that backs up into the esophagus and throat where it may come in contact with the larynx
  • Weakened immune system
  • Laryngeal dysplasia—a precancerous condition

লক্ষণ

উপসর্গ অন্তর্ভুক্ত হতে পারে:

  • Persistent cough, hoarseness, or sore throat
  • Abnormal lump in the throat or neck
  • গিলতে অসুবিধা
  • গিলে ফেলার সময় ব্যথা
  • Frequent choking on food
  • শ্বাস নিতে কষ্ট হওয়া

আপনার ডাক্তার আপনার লক্ষণ এবং চিকিৎসা ইতিহাস সম্পর্কে জিজ্ঞাসা করবে। একটি শারীরিক পরীক্ষা সম্পন্ন করা হবে।

Your bodily tissue may need to be tested. This can be done with biopsy.

Your internal structures may need to be viewed and examined. This can be done with:

  • Laryngoscopy
  • এক্স-রে
  • কম্পিউটেড টমোগ্রাফি (সিটি) স্ক্যান
  • ম্যাগনেটিক রেজোন্যান্স ইমেজিং (MRI) স্ক্যান

চিকিৎসা

When laryngeal cancer is found, staging tests are performed to find out if the cancer has spread and, if so, to what extent. Treatment depends on the stage of the cancer. For early stage laryngeal cancer, either surgery or radiation alone are the most common and appropriate therapies offered. For more advanced disease, either radiation with chemotherapy or surgery followed by radiation is the most common treatment given.

সার্জারি

Surgery requires removal of a cancerous tumor and nearby tissue, and possibly nearby lymph nodes. Surgeries for laryngeal cancer include:

  • Total laryngectomy—This involves the removal of the larynx, including the vocal cords.
  • Partial laryngectomy—In this procedure, the surgeon removes the cancerous tissue while leaving as much of the vocal cords as possible.
  • Tracheotomy—To help with breathing, a hole is made in the neck below the larynx. This may be temporarily necessary after surgery, or permanently placed in the case of laryngeal tumors that are too large to be removed.
  • Neck dissection—This involves the removal of the lymph nodes and part of the neck muscles to determine the spread of cancer.

রেডিয়েশন থেরাপি (বা রেডিওথেরাপি)

Radiation therapy is the use of radiation to kill cancer cells and shrink tumors. This may be external radiation therapy, where the beam is directed at the tumor from a source outside the body.

কেমোথেরাপি

Chemotherapy is the use of drugs to kill cancer cells. This form of treatment may be given in many forms including pill, injection, and catheter. The drugs enter the bloodstream and travel through the body killing mostly cancer cells, but also some healthy cells. Chemotherapy may be used to reduce the size of a particularly large cancer.

প্রতিরোধ

Since laryngeal cancer is extremely rare in nonsmokers, the best way to prevent this type of cancer is by not smoking. Other measures you can take to reduce your risk of laryngeal cancer include:

  • Avoiding excessive alcohol use
  • Protecting yourself from toxic exposures that have been linked to laryngeal cancer
