What are the causes of throat cancer?

Throat cancer occurs when malignant tumors develop in the throat, voice box or tonsils. If someone gets throat cancer, he may have symptoms like a cough, hoarse voice, ear pain, a sore throat or difficulty swallowing.

Throat cancer is caused by genetic mutations of the cells in the throat. The cause of the mutations is still unknown at present, but doctors have found some factors that may increase the risk of getting throat cancer. These factors include:

  • Smoking or chewing tobacco.
  • Excessive drinking.
  • Not eat enough fruits and vegetables.
  • Gastroesophageal reflux disease (GERD).
