Oral cancer is a type of cancer that affects the mouth and surrounding tissues. It is a serious medical condition that can be fatal if not detected and treated early. In this article, we will discuss the causes, symptoms, diagnosis, and treatment of oral cancer, as well as the steps that can be taken to prevent it.
Causes of Oral Cancer:
Oral cancer can develop when cells in the mouth or throat grow uncontrollably, forming a mass or tumor. Although the exact causes of oral cancer are not fully understood, several factors can increase the risk of developing this disease.
-
Tobacco Use:
Tobacco use is one of the most significant risk factors for oral cancer. Smoking cigarettes, cigars, or pipes, and using chewing tobacco or snuff can all increase the risk of developing oral cancer. Tobacco contains harmful chemicals that damage cells in the mouth and throat, making them more susceptible to cancer.
-
Heavy Alcohol Consumption:
Heavy alcohol consumption can also increase the risk of oral cancer. Alcohol can damage cells in the mouth and throat, making them more vulnerable to cancer. When combined with tobacco use, the risk of developing oral cancer is even higher.
-
Human Papillomavirus (HPV):
Certain strains of the human papillomavirus (HPV) can increase the risk of oral cancer. HPV is a sexually transmitted infection that can affect the mouth and throat. It is estimated that HPV is responsible for a growing number of oral cancer cases, particularly in younger people who do not have a history of tobacco or alcohol use.
-
Sun Exposure:
Prolonged exposure to the sun can increase the risk of lip cancer. The lips are particularly vulnerable to sun damage, and people who work outside or participate in outdoor activities for long periods may be at higher risk.
-
Poor Oral Hygiene:
Poor oral hygiene can lead to chronic inflammation and infection in the mouth, which can increase the risk of oral cancer. People who do not brush and floss regularly, and those with chronic gum disease, are more likely to develop oral cancer.
-
Family History:
Some people may have a genetic predisposition to oral cancer. If a close family member has had oral cancer, the risk of developing the disease may be higher.
-
Age and Gender:
Oral cancer is more common in older adults, particularly those over the age of 50. Men are also more likely than women to develop oral cancer.
It is essential to note that having one or more risk factors for oral cancer does not mean that a person will develop the disease. However, it is important to be aware of these risk factors and take steps to reduce the risk of developing oral cancer, such as quitting tobacco, limiting alcohol consumption, practicing good oral hygiene, and protecting the lips from sun damage.

Symptoms of Oral Cancer:
Oral cancer can develop in different parts of the mouth, including the tongue, lips, gums, tonsils, and throat. Like other types of cancer, early detection is critical for successful treatment. Here are some of the most common symptoms of oral cancer:
-
Mouth sores or ulcers:
Sores or ulcers that do not heal within two weeks can be a sign of oral cancer. They may be painful or painless and can appear on the tongue, gums, or roof of the mouth.
-
Red or white patches:
Red or white patches on the tongue or lining of the mouth can indicate oral cancer. These patches may be painless, and they may not go away on their own.
-
Swelling or lumps:
lump or swelling in the mouth, neck, or throat can be a sign of oral cancer. These lumps may be painless or painful, and they may be accompanied by difficulty swallowing or chewing.
-
Persistent sore throat:
A persistent sore throat that does not go away with treatment can be a sign of oral cancer. This symptom may be accompanied by hoarseness or difficulty speaking.
-
Changes in speech or voice:
Oral cancer can affect the way you speak or your voice. You may notice changes in your voice quality or experience difficulty pronouncing certain words.
-
Difficulty swallowing:
Oral cancer can make it difficult or painful to swallow. You may experience a sensation of something being stuck in your throat, or you may cough or choke when trying to swallow.
-
Ear pain:
Oral cancer can cause pain or discomfort in the ear on the same side as the affected area. This symptom may be accompanied by swelling or numbness in the face.
It is essential to note that not all symptoms of oral cancer indicate cancer and many benign conditions can cause similar symptoms. However, if you experience any of these symptoms for more than two weeks, it is essential to schedule an appointment with your doctor or dentist. They can examine your mouth and throat for any signs of oral cancer and recommend further testing if necessary.
Diagnosis of Oral Cancer:
The diagnosis of oral cancer typically involves a physical exam and several tests. During the physical exam, a healthcare professional will examine the mouth, tongue, and throat for signs of cancer.
If oral cancer is suspected, several tests may be ordered, including:
-
Physical Exam:
During a physical exam, your doctor or dentist will examine your mouth, tongue, and throat for any signs of oral cancer. They will look for abnormalities such as lumps, bumps, or patches of discolored tissue. They may also feel your neck for any enlarged lymph nodes or masses.
-
Biopsy:
If your doctor or dentist detects any abnormalities during a physical exam, they may perform a biopsy. A biopsy involves removing a small sample of tissue from the affected area for examination under a microscope. This procedure is typically done under local anesthesia and can be done in a dental office or clinic.
-
Endoscopy:
An endoscopy is a procedure in which a small, flexible tube with a camera on the end is inserted into your mouth and throat to view the affected area. This procedure can help your doctor or dentist get a closer look at any abnormalities and can be done under local or general anesthesia.
-
Imaging Tests:
Imaging tests such as X-rays, CT scans, MRI scans, and PET scans may be used to help diagnose oral cancer and determine the extent of the disease. These tests can help your doctor or dentist see inside your body and detect any abnormalities that may be present.
-
Blood Tests:
Blood tests may be done to check for certain biomarkers that may be present in people with oral cancer. These tests can help your doctor or dentist diagnose oral cancer and monitor your response to treatment.
Treatment of Oral Cancer:
The treatment of oral cancer depends on several factors, including the location and stage of cancer, as well as the overall health of the patient. Treatment options for oral cancer may include:
- Surgery: Surgery is often used to remove cancerous tissue from the mouth or throat. Depending on the location and stage of cancer, surgery may involve removing part or all of the affected tissue.
- Radiation therapy: Radiation therapy uses high-energy radiation to kill cancer cells. It may be used alone or in combination with surgery
- Chemotherapy: Chemotherapy uses drugs to kill cancer cells. It may be used alone or in combination with surgery and radiation therapy.
- Targeted therapy: Targeted therapy uses drugs that specifically target cancer cells. This type of therapy is typically used in advanced cases of oral cancer.
- Immunotherapy: Immunotherapy uses the body’s immune system to fight cancer. This type of therapy is still being studied for its effectiveness in treating oral cancer.
Palliative care: Palliative care focuses on managing symptoms and improving the quality of life for people with advanced oral cancer. This may include pain management, nutrition support, and counseling.
