Cancer in Throat Causes, Symptoms and Treatment

The cancer of the larynx , better known as throat cancer , it happens most often in the head and neck. It happens due to genetic mutations in the cells, which grow rapidly and often form malignant tumors that can spread to other areas of the body. The tumor can settle in three areas of the larynx, being: the supraglottic, the glottis or subglote. Most cases (about 2/3) occur in the glottis, vocal cord region.

The number of deaths from the disease, according to INCA (National Cancer Institute), was 4,141 in 2013, of which 3,635 were men. Thus, it is possible to affirm that cases occur more frequently in males.

Causes of throat cancer:

The causes have not yet been scientifically proven, but there is a theory that factors such as smokinginfluence the mutation of the cancer cell. Other likely factors that influence cancer contraction are:

 Infections with human papillomavirus (HPV)
  • Exposure to toxic substances such as asbestos
  • Excessive alcohol consumption
  • Lack of vitamin A

 Throat Cancer Symptoms:

The symptoms of throat cancer vary in each case. Not all patients show signs of the disease, and those who present often confuse with symptoms of other illnesses.

The main signs presented are:

  • Change of voice or hoarseness of voice
  • A lot of cough
  • Sore throat that usually does not heal
  • Feeling of discomfort in the throat, as if something were there
  • Difficulty in swallowing food
  • Lump in the neck
  • Weight loss
  • Difficulty breathing

How To Diagnose Throat Cancer:

Prior to the specific tests, the family history favorable to the development of the disease may be a

step if you have the diagnosis. After this the medical examination is performed and then, according to the results, the specific examinations can be ordered.

These tests are: computed tomography, magnetic resonance imaging, chest X-ray and, finally, tumor biopsy. The biopsy is done by surgical incision in the neck, or by endoscopy.

Treatment for throat cancer largely depends on the degree of disease and the size of the tumor. These treatments are tailor-made and vary from patient to patient. The most common are: surgeries, radiotherapy, chemotherapy, proton therapy, specific therapies and clinical trials.

  • Surgeries for the removal of malignant laryngeal tumor can be performed via endoscopy, laser or by means of robots, all to allow it to affect as little as possible swallowing and speech.
  • Chemotherapy is used to decrease or kill cancer cells and is often used with therapies, which are many.
  • Radiation therapy, for example, involves the placement of radioactive granules near the tumor. Proton Therapy is done by applying a dose of radiation directly to the tumor without damaging the nearest tissue.
  • There are also specific therapies and clinical trials. In these experimental drugs are used and the result is not guaranteed and in those, specific drugs are used to prevent the growth of the modified cell.
