Oral Cancer

  • Oral Cancer
What is Oral Cancer ?
Oral cancer or mouth cancer include cancer of lip, tongue, area between tongue and lower jaw bone (floor of mouth), cheek, upper and lower jaw bones and bony (hard) palate.
Can it be cured ?

Oral cancer can be cured if detected early. Hence early diagnosis and treatment is crucial for successful outcome. It is important to be aware of symptoms and warning signs of cancer so that treatment can be started on time.

How common is oral cancer ?​
​It is the most common cancer amongst Indian males. It is also the most common cause of deaths due to cancer in our country. This is the fourth common cause of cancers in women but in some part of our country, it is the one of the commonest cancer in women. Every year approximately 1 lakh new cases of oral cancers are detected in India. Unfortunately half of them die within one year of detection. The main reason behind it that 60-70 percent of these cases are detected in advanced stages.
Symptoms & Warning Signs
  1. Non healing ulcer i.e. an ulcer which does not heal despite treatment
  2. Any rough area inside mouth
  3. Any growth that bleeds on touch
  4. White patch or red patch inside mouth
  5. Sudden fall of tooth
  6. Change in size of dentures
  7. Altered speech
  8. Difficulty in eating
  9. Pain at the back side of throat radiating to ear
  10. Neck swelling
  11. Skin ulcer or swelling over face
What are the causes of oral cancer
Tobacco consumption is the most common cause for oral cancer. It is consumed in various forms. It may be chewed or it may be smoked. Chewed tobacco is used in various forms such as mawa, khaini, pan, pan masala etc.  It may be smoked in the form of bidi, Hukkah, cigarette etc. Gutka and areca nut or supari also cause mouth cancer and rampantly used in some part of our country. All these forms are harmful and cause cancer.
Alcohol is another cause for oral cancer especially floor of mouth cancers. Risk of cancer is increased many folds when both tobacco and alcohol are consumed together. Sharp tooth and ill fitting dentures causing repeated trauma can also cause oral cancer. Poor Oro dental hygiene, HPV virus infection, dietary deficiencies are other causes of mouth cancer.

Diagnosis

Clinical Examination

Patient is examined clinically by the oncologist and extent of tumor is determined. Based on clinical examination finding further tests are ordered.

Biopsy

Biopsy is done to confirm the presence and type of cancer. It is often done as an out patient procedure. In this, a small piece from the growth is taken and sent for pathological examination. Biopsy is essential before starting cancer treatment.

Imaging

Imaging is done to know tumor extent in all dimensions including deeper tissues. CT scan, MRI or PET CT is done based on tumor location, site and size.

Staging

Tumor is staged based on clinical and radiological findings. It is staged as early stage (stage I/II ) or advanced stage (stage III/IV).

Treatment

Treatment of oral cancer is primarily by surgery. Radiation therapy alone or along with chemotherapy is required in late stages.

Surgery

Surgery includes complete excision of tumor along with a safety margin of normal tissue all around the tumor. Extent of surgery depends on tumor size and involvement of adjoining structures. Surgery includes excision of main tumor and removal of draining lymph nodes of neck called as neck dissection.

Radiotherapy

Radiotherapy is used mainly in advanced cases after surgery so that chances of recurrence can be reduced.

Chemotherapy
In oral cancer, chemotherapy is mainly used for the treatment of advanced stage IV cancers where it is used along with radiotherapy after surgery. Chemotherapy alone is generally used in cases where either the tumor is very advanced and has spread to distant areas such as lung, liver or bone or it has come back again and either surgery or radiotherapy can not be given. Intent of treatment in this situation is palliative that means chemotherapy is not going to completely remove the disease but is given to slow the tumor growth.
Targeted therapy

In this therapy, drugs are used which target specific parts of cancer cells such as proteins or genes involved in tumor growth. These are used along with chemotherapy in advanced cases where surgery and radiation therapy are not an option.

Immunotherapy

Immunotherapy is a type of therapy which acts on body’s immune system to fight cancer. For oral cancer it is used in advanced cases where surgery can not be done and radiotherapy is not possible. Immunotherapy is given either alone or along with chemotherapy.

Follow up
It is very important to be in regular follow up after cancer treatment. This is done to detect future recurrences at the earliest. At each follow up visit, patient is examined clinically by oncologist. Imaging may be required based on tumor stage and symptoms. Follow up is done at 2-3 months for initial 2 years, 3-6 monthly for next 3 years and annually thereafter.
