Oral Cancer

Overview on Oral Cancer:

The uncontrollable growth of cells that invade and cause damage to the surrounding tissue is known as cancer. Oral cancer is a cancer that develops in the tissues of mouth or the throat. Most of the oral cancer develops in the squamous cells present in the mouth, tongue, and lips. Usually oral cancers are most often discovered after they have spread to the lymph nodes of the neck. It is essential to have early detection so as to survive oral cancer.

Oral cancer has 4 stages. The stage 1 and stage 2 of oral cancer involve small tumor. In these two stages, cancer cells have not spread to the lymph nodes. However, stage 3 and stage 4 are considered as advanced stages of the oral cancer where tumors are large and the cancer cells have usually spread to the lymph nodes or other parts of the body.

It is noted that the survival rate after 1 year of all stages of oral cancer is 81%. After 5 years of the oral cancer, the survival rate is 56% and it is 41% after 10 years of the oral cancer. Earlier diagnosis at an early stage makes it very much possible for best of the treatment and gets a higher chance of survival after the treatment.

Diagnosis for Oral Cancer:

Diagnosis for oral cancer includes the following.

  • Oral Cancer Screening Examination: Your dentist will get to know about any lumps or irregular tissue changes in your head, face, neck and oral cavity. While examining your mouth, he or she will look for any discoloured tissue or sores and also check for the signs and symptoms of oral cancer.
  • Oral Brush Biopsy: If your dentist finds any suspicious tissue in mouth then he or she may go for oral brush biopsy. This test is painless. It involves taking a small tissue sample and analyzing it for abnormal cells.
  • Scalpel Biopsy: In case the suspicious tissue after oral brush biopsy looks more suspicious, your dentist may go for a scalpel biopsy which requires local anesthesia. The test would detect oral cancer at an early stage before it could have had a chance to spread.

Apart from all the above mentioned tests, your dentist may also recommend you to undergo the following diagnosis procedures.

  1. X-rays: So as to see if cancer cells have spread to the jaw, chest or the lungs.
  2. CT Scan: This is done to reveal any tumor in the mouth, throat, neck, lungs or anywhere else in the body.
  3. PET Scan: This is done to determine if the cancer has travelled to the lymph nodes or other organs.
  4. MRI Scan: This shows a more accurate image of the head and neck and thus dentist can determine the extent or the stage of the cancer with an MRI scan.
  5. Endoscopy: This is done to examine the nasal passages, inner throat, sinuses, windpipe and trachea.
