Oral cancer can be treated with Surgery or Radiotherapy or With a combination of both.


Surgery is performed to remove tumor or cancerous lymph nodes.

  • It is simple and fast.
  • No cosmetic and functional defects after surgery.
  • Surgery is less expensive.


  • Treatment time is longer as compared to surgery.
  • There are many side effects like Dry mouth, caries and cancer of the bone at the site of radiotherapy.
  • Can usually be given only once.
  • Not suitably for treatment if lesion is near the bone.


  • In this form of radiotherapy, radiation is administrated through catheters surgically at the site of lesion.
  • Brachytherapy does not damage the normal tissues surrounding the lesion such as bone,  salivary glands, and spinal cord.
  • Lymph nodes are damaged by Brachytherapy alone so external beam radiotherapy is used in combination with Brachytherapy.


  • Here anti-cancer drugs are used to treat oral cancer of early stages, in which the drugs are given into the vein or taken directly into the mouth,  which later allows them to reach into the bloodstream and reach to the site.
  • Chemotherapy is also given with radiation therapy and is also given after surgery.


Most commonly used Drugs are.

  • Carboplatin
  • Hydroxyurea
  • Cisplatin
  • Dicetaxel

After treatment, there would be frequent checkups. There are always some PROS and CONS associated with the treatment method depending upon its severity and stage. Stage 1 and 2 are easily curable with very good prognosis.


WILL POWER, HOPE and POSITIVE MINDSET are the keys to beat any disease. Here’s a story of positive attitude-
There was a cancer warrior with stage 4. One day he decides to grow some DAFFODILS in the belief that he will visualize their blooms the next spring. And at worst, if he wouldn’t be there to see them, he has made a small part of MOTHER EARTH beautiful because of them.
We can win our battle with this life threatening disease by following a healthy routine
