Oral Cancer: Signs, Risk Factors and Early Detected


Oral cancer refers to cancers that develop in the mouth, lips, tongue, gums, cheeks, floor of the mouth, palate, or throat region. Although oral cancer is less common than tooth decay or gum disease, it is a serious condition that can significantly affect health, speech, swallowing, and quality of life. Oral cancer occurs when abnormal cells grow uncontrollably in the tissues of the mouth or throat.


Early detection is extremely important. When diagnosed early, oral cancer is often more treatable and outcomes are generally better. Dentists play an important role in screening for oral cancer during routine dental examinations by checking the soft tissues of the mouth, tongue, lips, and throat for any unusual changes.

There is no single cause of oral cancer, but several factors can significantly increase the risk.

Smoking and Tobacco Use

Smoking is one of the largest risk factors for oral cancer.

This includes:

  • Cigarettes
  • Cigars
  • Pipes
  • Chewing tobacco

Tobacco contains harmful chemicals that damage the cells lining the mouth and throat.

Alcohol Consumption

Heavy alcohol use also increases the risk of oral cancer, particularly when combined with smoking.

Human Papillomavirus (HPV)

Certain strains of HPV, particularly HPV-16, are associated with cancers involving the throat and tonsil region.

Sun Exposure

Excessive sun exposure can increase the risk of cancer affecting the lips.

Age

Oral cancer is more common in older adults, although it can occur at any age.

Premedication involves taking a tablet before your appointment to help you feel relaxed.


How it works:

These medications (commonly from the benzodiazapine family) help to:

  • Reduce anxiety
  • Promote relaxation
  • Make the appointment feel easier to manage


You will still be awake and able to respond, but feel calmer and less overwhelmed


What to Expect:

  • Taken at home one hour prior to appointment
  • You may feel drowsy or sleepy
  • You will need someone to drive you to and from your appointment
  • Effects can last for several hours


Is it Safe?

When prescribed appropriately, premedication is safe and widely used in dentistry. Your dentist will review your medical history to ensure it is suitable for you.

Oral cancer may not always cause pain in its early stages, which is why regular examinations are important.

Possible warning signs include:

    • A mouth ulcer that does not heal within two weeks
    • Red or white patches in the mouth
    • A lump, swelling, or thickened area
    • Persistent sore throat
    • Difficulty swallowing
    • Pain when chewing
    • Numbness in the mouth or lips
    • Loose teeth without obvious cause
    • Persistent hoarseness
    • Bleeding areas in the mouth
    • Jaw stiffness or difficulty moving the jaw
    • Ear pain without ear infection

Any unusual area that does not heal or improve should be assessed promptly.

Oral cancer can appear in different ways, including:

    • A persistent ulcer
    • A raised lump
    • A rough or thickened patch
    • White patches (leukoplakia)
    • Red patches (erythroplakia)
    • Mixed red and white areas

Not all mouth ulcers or patches are cancerous, but persistent changes should never be ignored.

During a dental examination, your dentist will assess:

    • The lips
    • Tongue
    • Floor of the mouth
    • Cheeks
    • Gums
    • Soft palate and throat tissues

If an unusual area is found, your dentist may:

    • Monitor the area
    • Refer you to a specialist
    • Recommend a biopsy

A biopsy involves taking a small tissue sample for laboratory testing.

Treatment depends on:

    • The location of the cancer
    • The stage and size
    • Whether it has spread
    • The patient’s general health

Treatment may involve:

    • Surgery
    • Radiation therapy
    • Chemotherapy
    • Immunotherapy

Some patients require a combination of treatments.

Although not all cases are preventable, the risk can be reduced by:

    • Avoiding smoking and tobacco use
    • Limiting alcohol intake
    • Protecting lips from the sun
    • Maintaining good oral health
    • Eating a healthy diet
    • Attending regular dental examinations
