Don’t ignore suspicious lumps and lesions in your mouth.

Signs of oral pathology or oral cancer


Sores, lumps, and lesions can be caused by underlying dental issues such as tooth or gum abscess. They can also be telling signs of oral cancer. Nonetheless, it’s always recommended to see an oral surgeon when you notice a persistent lump or lesion in your mouth.

The inside of your mouth is lined with the mucous membrane – a smooth, coral pink membrane. Any alteration of this appearance could be a sign of an underlying problem.

Oral cancer refers to cancer that develops in any part of the oral cavity (inside the mouth). It can occur on the tongue, gums, lips, roof of the mouth, under the tongue, and the inner side of the cheeks.

Besides persistent lumps and lesions, other common symptoms include:

  • Whitish or reddish patches inside your mouth
  • Chronic sore throat or hoarseness
  • Difficulty in talking and chewing
  • Persistent bad breath
  • Loose teeth
  • Painful swallowing
  • Ear pain
  • Thickening in the cheeks
  • Dramatic weight loss

What to do with sores, lumps, and lesions

Ensure you make an appointment with our oral surgeons if any of the signs last for more than two weeks. Additionally, any person experiencing oral pain without any particular cause may be at risk.


Oral cancer treatment depends on the cancer’s location in the mouth, its stage, your overall health, as well as your personal preferences. Generally, it involves surgery to remove the tumor followed by radiation therapy to destroy the cancer cells. In some cases, reconstruction is needed to correct the structures of the affected mouth or jaw.

We recommend that you perform a monthly oral cancer self-examination to detect the signs or oral cancer early.

Early diagnosis can double a patient’s successful treatment rate

Catching the cancer early can greatly improve the patient’s survival rate. If the cancer hasn’t spread, the survival rate is over 80%.

When it comes to sores and lumps in your mouth, be proactive

Most of the time the lumps and lesions in your mouth cavity aren’t cancer. A biopsy is done to determine the type of disease in your mouth, its severity, and the appropriate treatment methods.

Some of the conditions that may also cause lumps and lesions in your mouth include dental cysts, canker sores, oral thrush, periodontal abscess, and oral fibroma.

It is our goal to encourage the prevention and early detection of any serious oral complications. If any sores, lumps, and lesions last for more than two weeks, please call our oral surgery clinic right away so we can identify the underlying cause and treatment.
