Overview of Oral Cancer: Understanding the Disease

Oral cancer, also known as mouth cancer, is a type of head and neck cancer that starts in the mouth. It can affect the lips, tongue, cheeks, the floor of the mouth, hard and soft palate, sinuses, and throat. Oral cancer can be life-threatening if not diagnosed and treated early.

Causes and Risk Factors

There are several factors that can increase the risk of developing oral cancer, including:

  • Tobacco use (including cigarettes, cigars, pipes, and smokeless tobacco)
  • Heavy alcohol consumption
  • Human papillomavirus (HPV) infection
  • Poor oral hygiene
  • Poor diet lacking fruits and vegetables

It’s important to note that not everyone with these risk factors will develop oral cancer, but being aware of them can help in early detection and prevention.

Symptoms and Diagnosis

Common symptoms of oral cancer may include:

  • Persistent mouth sores that do not heal
  • A lump or thickening in the cheek
  • Difficulty chewing or swallowing
  • Persistent sore throat
  • Swelling of the jaw

Diagnosis of oral cancer usually involves a thorough physical examination of the mouth, throat, and neck, as well as biopsies of any suspicious areas.

Prevention and Early Detection

Preventive measures and early detection play a crucial role in managing oral cancer. Regular dental check-ups, avoiding tobacco and excessive alcohol consumption, and maintaining good oral hygiene are key preventive strategies. Early detection through regular self-examinations and screenings can lead to better treatment outcomes.

According to the American Cancer Society, an estimated 54,000 new cases of oral cavity and oropharyngeal cancers will be diagnosed in 2021 in the United States, with approximately 10,850 deaths attributed to these cancers.
