Oral Cancer

Oral cancer is a type of cancer that develops in the mouth or throat tissues. It’s part of a bigger category of tumors known as head and neck cancers. The majority form in the squamous cells of your mouth, tongue, and lips.

Oral cancer affects more than 49,000 people in the United States each year, with the majority of instances happening in persons over the age of 40. Oral cancer is usually found after it has spread to the lymph nodes in the neck.

Oral cancer usually affects persons in their sixties and seventies. Your lips and the earliest parts of your tongue, as well as the roof and floor of your mouth, are all affected by oral cancer. It also affects your oropharynx, which includes the last section of your tongue and the roof of your mouth, as well as your tonsils, sides, and back of your throat.

What is Oral Cancer?

Oral cancer, often known as mouth cancer, is a type of cancer that affects the inside of the mouth. Oral cancer can resemble a common condition with your lips or mouth, such as white spots or bleeding sores.

The difference between a common condition and cancer is that these changes are permanent. Oral cancer can spread from your mouth and throat to other parts of your head and neck if left untreated.

Symptoms of Oral Cancer:

• Swellings/thickenings, lumps or bumps on the lips, gums, or other places inside the mouth, rough spots/crusts/or eroded areas
• Velvety white, red, or speckled (white and red) patches in the mouth.
• Mouth bleeding for no apparent reason
• Any part of the face, mouth, or neck that has unexplained numbness, loss of feeling, or pain/tenderness
• Sores that bleed readily and do not heal within two weeks on the face, neck, or mouth
• A throbbing sensation or the sensation that something is stuck in the back of the neck
• Chewing, swallowing, speaking, or moving the jaw or tongue are all difficult tasks.
• Hoarseness, a persistent sore throat, or a change in voice
• Ear ache
• The way your teeth or dentures fit together has changed.
• Weight loss that is dramatic

What causes Oral Cancer?

Mouth cancers develop when the DNA of cells on the lips or in the mouth undergoes mutations. The DNA of a cell includes the instructions that tell it what to do. When healthy cells would perish, the genetic alterations tell the cells to keep growing and dividing. A tumor can occur when abnormal mouth cancer cells congregate. They may spread from inside the mouth to other sections of the head and neck, as well as other parts of the body, over time

Risk factors

Factors that can increase your risk of mouth cancer include:

• Tobacco use in any form, such as cigarettes, cigars, pipes, chewing tobacco, and snuff,
• Excessive alcohol consumption
• Lips that have been exposed to too much sunlight
• Human papillomavirus (HPV)
• Immune system dysfunction

Prevention

There is no definite way to avoid mouth cancer. You can, however, lower your chance of mouth cancer if you:

• Stop using tobacco or don’t start using it at all.
• If you drink alcohol at all, do it in moderation.
• Excessive sun exposure to your lips should be avoided.
• See your dentist on a regular basis.

Oral Cancer Stages:

• Stage 1: The tumor is 2 centimeters (cm) or less in diameter and has not migrated to the lymph nodes.
• Stage 2: The tumor is 2-4 cm in diameter and has not migrated to the lymph nodes.
• Stage 3: Either the tumor is greater than 4 cm and has not spread to the lymph nodes, or it is any size and has spread to one lymph node but not to other parts of the body.
• Stage 4: Tumors of any size have expanded to surrounding tissues, lymph nodes, or other parts of the body, and cancer cells have spread to nearby tissues, lymph nodes, or other parts of the body.

Oral Cancer Treatment

The majority of patients with mouth cancer are treated with surgery. Most of these tumors can be removed through the mouth, but others may require a more invasive procedure. The size, stage, and location of the tumor all influence which surgery is best for the patient.

One of the operations described below may be used to remove the tumor, depending on its location and size:

• Primary tumor resection The surgeon removes the cancerous tissue in your mouth, as well as a little amount of normal tissue around the tumor. Reconstruction may be done to repair the area if a considerable amount of tissue is removed. Doctors accomplish this by removing healthy tissue from another section of your body. It’s possible to employ skin, muscle, or even bone.
• Mandible resection The surgeon may remove part or all of your jawbone (mandible) if the malignancy is in your jawbone (mandible) (called mandibulectomy). Bone from another area of your body, bone from a donor, or a metal plate can all be used to rebuild the jawbone.
• Maxillectomy If the cancer is in the bone that holds your top teeth (maxilla) in the front area of your mouth, your surgeon may need to remove some of the bone. A prosthesis may be prescribed for you. This is a unique device that inserts into your mouth’s roof to hide the surgical hole. You might be able to receive the prosthetic before the procedure. Following surgery, it will be refitted by a professional.
• Mohs micrographic surgery Mohs surgery is a type of micrographic surgery. If you have a cancer in your lip, the Mohs technique may be performed to remove it. The idea is to keep your lip’s function and appearance intact. One tiny layer of skin is shaved off at a time by the surgeon. Each layer is immediately inspected for cancer cells. The procedure is finished when no more cancer cells are seen and no more layers of skin are removed.
• Removal of the tongue The tongue is removed. For tongue cancer, a full or partial removal of the tongue (called a glossectomy) may be required.
• Neck dissection If your cancer has spread to your lymph nodes in your neck, you may need this procedure. The lymph nodes in the neck, as well as some surrounding tissue, are removed by the surgeon. This is done at the same time as the tumor removal procedure.
• Tracheostomy If your cancer or surgery is making it difficult for you to breathe, you may need this operation. A hole is made in the front of your neck, into your windpipe, by the surgeon (trachea). A short tube called a tracheostomy (trach) tube keeps the hole open. The tube is then used to breathe through. A tracheostomy might be temporary, only needed until the swelling subsides. It could be temporary or permanent, meaning you’ll have it for the rest of your life.
• Feeding tube placement If your cancer or therapy makes it difficult for you to eat, your surgeon will insert a gastrostomy tube (g-tube or PEG tube) into your stomach. It enters your body through the skin that covers your stomach. Another alternative is to insert the tube down your nose, down your esophagus (swallowing tube), and into your stomach. A nasogastric feeding tube, or NG tube, is used for this. The feeding tube is then used to deliver liquid nutrition directly to your stomach. An NG tube is only used for a brief period of time. A PEG or g-tube can be used for a short time or for a long time.

When is Oral Cancer Treatment needed?

If you are suffering from any of the above mentioned symptoms, you should see a doctor immediately who would advise tests to confirm the diagnosis. If you are diagnosed with oral cancer, you need to start the treatment immediately.
