What
is Oral Cancer?
Oral cancer is cancer of the mouth. It can occur in the lining of the mouth or in the deeper tissues such as the bone, muscle, and nerves. Cancer of the mouth lining is called a carcinoma and makes up 90% of all oral cancer. Cancer of the mouth is most common in people over 40 years of age, but it can occur in younger people.
Oral cancer is one of the most preventable cancers when caught early. Unfortunately, more people die from oral cancer than from cervical cancer, Hodgkin's lymphoma, or melanoma. This is because oral cancer is often diagnosed when it is already advanced. Early diagnosis and treatment is the most effective way to treat oral cancer.
Oral cancer symptoms
Some of the most common oral cancer symptoms and signs include:
- Persistent mouth sore: A sore in the mouth that does not heal is the most common symptom of oral cancer
- Pain: Persistent mouth pain is another common oral cancer sign
- A lump or thickening in the cheek
- A white or red patch on the gums, tongue, tonsil, or lining of the mouth
- A sore throat or feeling that something is caught in the throat that does not go away
- Difficulty swallowing or chewing
- Difficulty moving the jaw or tongue
- Numbness of the tongue or elsewhere in the mouth
- Jaw swelling that makes dentures hurt or fit poorly
- Loosening of the teeth
- Pain in the teeth or jaw
- •Voice changes
- A lump in the neck
- Weight loss
- Persistent bad breath
Diagnosis of Oral Cancer
A number of tests are performed for
diagnosing mouth cancer that include –
·
Biopsy
: A small tissue
sample is taken in biopsy that is further sent to a laboratory for determining
the type of cells and whether they are cancerous or non-cancerous.
·
Throat
and Mouth Examination : A
special instrument known as flexible laryngoscope is used for viewing within
the throat and mouth.
Certain other tests are also required
for determining the spread of the cancer. These tests are –
·
A
Barium Swallow and Meal Test : This
test requires a patient to swallow a drink having barium. An x-ray will present
images of abnormal growths in the digestive system down to the stomach.
·
X-rays
: X-rays are done of
the lower and upper jaw or a chest x-ray can also be done.
·
Endoscopy
: This test helps in
viewing the body from within. An endoscope (a narrow and flexible tube having a
telescopic camera) is used for performing this test.
·
Certain other
biopsies of nearby lymph nodes are also done.
Oral Cancer Treatment in India
Surgery
Surgery for mouth cancer may include:
·
Surgery
to remove the tumor Your
surgeon may cut away the tumor and a margin of healthy tissue that surrounds
it. Smaller cancers may be removed through minor surgery. Larger tumors may
require more-extensive procedures. For instance, removing a larger tumor may
involve removing a section of your jawbone or a portion of your tongue.
·
Surgery
to remove cancer that has spread to the neck If cancer cells have spread to the
lymph nodes in your neck, your surgeon may recommend a procedure to remove
cancerous lymph nodes and related tissue in the neck (neck dissection).
·
Surgery
to reconstruct the mouth After
an operation to remove your cancer, your surgeon may recommend reconstructive
surgery to restore the appearance of your face or to help you regain the
ability to talk and eat. Your surgeon may transplant grafts of skin, muscle or
bone from other parts of your body to reconstruct your face. Dental implants
may replace your natural teeth.
Non-Surgery
·
Biological
Therapy : The activity of
the cancer cells is changed with the help of biological therapy. A type of
biological therapy is known as Cetuximab that is also referred to as a
monoclonal antibody. The surface of the cancer cells that triggers the
development of cancer cells is blocked with the help of Cetuximab.
·
Radiotherapy
: Radiotherapy uses
doses of radiation to kill cancerous cells. It may be possible to remove the
cancer using radiotherapy alone, but it is usually used after surgery to
prevent the cancer from re-occurring.
Internal radiotherapy : Internal radiotherapy is a type of
radiotherapy often used to treat cancers of the tongue that are in their early
stages. It involves sticking radioactive wires or needles directly into the
tumour while you are under a general anaesthetic (put to sleep). The wires or
needles then release a dose of radiation into the tumour.
Chemotherapy : Chemotherapy is often
used in combination with radiotherapy when the cancer is widespread, or if it
is thought there is a significant risk of the cancer returning.Chemotherapy
involves the use of powerful cancer-killing medicines.
