India is considered the oral cancer capital of the world. We have nearly 150,000 new patients every year.

And this is because of tobacco use. 1 in 3 adults in India use tobacco in some form. Unfortunately a vast majority of oral cancers are associated with tobacco use and alcohol.

We have the smoking kind of tobacco which includes the cigars, cigarettes, bindis. And the smokeless kind of tobacco which is the chewing tobacco- pan, khaini, jarda and you also have snuff which is inhaled.

 

Oral cancer or mouth cancer is when we get tumours inside the mouth.

There are a lot of areas or subsites in the mouth. The tongue is the most commonly involved part. The lips, under the surface of the mouth/ floor of the mouth, gums, jaw bone, cheek are also parts of the mouth that can get involved.

Around 80% of oral cancer is because of tobacco use in some form. There is a misconception that people have to use tobacco for a long time for them to develop oral cancer such as 20, 30, 40 years or continuous use, but what we are seeing unfortunately is a much shorter duration of tobacco use is enough to give you cancer. And this is why we are seeing an explosion in the cases of individuals with oral cancer in the younger population; sometimes as young as 20 years.

One theory to explain this explosion is that it is being combined with multiple other harmful substances. Areca nut on its own causes cancer, when you add it with alcohol and tobacco it probably accelerates cancer. There is also snake-lime or what is called chunnam which also irritates the cheeks, tongue and causes chronic irritation and cancer.

There are however individuals who say that they have never touched tobacco or alcohol and still develop cancer- how does this happen? This can be because of other causes such as:

  • chronic trauma- injury on the tongue, cheek/ lip from a sharp object such as a loose tooth or an ill fitting denture
  • Immunosuppressant medications over a long period of time can cause oral cancer
  • It can also be associated with HIV infection.
  • Individuals who eat a lot of spicy foods
  • Chronic mouth irritation
  • Poor oral hygiene

 

Symptoms of oral cancer:

– White patch or red patches on the tongue, cheeks or the gums. These patches don’t go away even after you rub them. This is called leukoplakia. They can be flat, sometimes they can be elevated. If it persists for more than 2-3 weeks it is better to get it checked.

 

  • Persistent ulcer or sore on the cheek, gum or tongue. These are usually painless in the initial stages and present with pain only in the later stages.
  • Thickening on the lip/ cheek/ tongue
  •  Loosening of the teeth
  • Swelling of the lymph nodes in the neck

 

How to get tested/ the investigations you can get done include:

  • It is better to get yourself examined by an ENT specialist, oncologist, or someone who deals with or sees oral cancers on the regular since they can be a little tricky.
  • Biopsy
  • Scanning- CT or MRI scan. This will help us by telling us the size of the tumour, the location and involvement of the surrounding structures.

 

Treatment modalities:

  • Surgery is the best treatment option to treat oral cancer. The cancerous area is removed along with a clear margin or a cuff of normal tissue.
  • Reconstruction surgery to restore the functions of the mouth- swallowing, eating, talking and speech
  • Grafting and scarless surgeries have come up with sophisticated equipment and medical advancements.
  • All cancers are not curable, some of the diseases are too advanced but the treatment modalities we have available with us today, to ensure that the patient is comfortable and has a good quality of life
