Oral Cancer Symptoms: Causes and Treatment Methods

Oral cancer is a serious disease caused by the uncontrolled growth of cells in the mouth. It can appear on the lips, tongue, gums, and inner cheeks, and if not detected early, it may spread to surrounding tissues. Smoking, alcohol consumption, and HPV infection are among the risk factors. Early symptoms include non-healing sores, oral patches, and difficulty swallowing.

What is Oral Cancer?

Oral cancer is a serious disease caused by the uncontrolled growth of cells in the mouth. It can occur in areas such as the lips, tongue, gums, and inner cheeks. If not diagnosed early, it can spread to surrounding tissues. The main risk factors include smoking, alcohol consumption, and HPV infection. Early symptoms include non-healing sores, patches in the mouth, and difficulty swallowing.

Where Does Oral Cancer Occur?

Oral cancer can appear in different parts of the mouth and throat. The most common areas include:

• Tongue: The edges and underside of the tongue are at higher risk.

• Lips: More common on the lower lip, especially due to excessive sun exposure.

• Palate: Can develop on the hard or soft palate.

• Gums: Sometimes mistaken for gum disease.

• Inner Cheeks and Floor of the Mouth: May present as abnormal growths.

Types of Oral Cancer

Oral cancer is classified based on the type of cells it originates from:

• Squamous Cell Carcinoma: Accounts for 90% of oral cancers, originating from squamous cells that line the mouth.

• Adenocarcinoma: Develops in the salivary glands.

• Melanoma: A rare but aggressive form occurring in the mouth.

• Lymphoma: Arises from lymph tissues in the mouth and throat.

Symptoms of Oral Cancer

Non-healing sores, abnormal growths in the tongue, palate, gums, or inner cheeks, unexplained pain and numbness, and loose teeth or sudden denture misalignment are among the common symptoms of oral cancer.

Common symptoms of oral cancer include:

• Non-healing sores: White or red lesions in the mouth or on the lips lasting more than two weeks.

• Lumps or Growths: Abnormal swelling, hard lumps, or irregular tissue changes.

• Pain or Numbness: Unexplained pain or loss of sensation in the tongue, lips, or mouth.

• Difficulty Chewing and Swallowing: Feeling of obstruction or discomfort when eating or swallowing.

• Voice Changes: Hoarseness or difficulty speaking.

• Loose Teeth and Denture Misfit: Unexpected tooth mobility or sudden denture misalignment.

• Persistent Sore Throat: A feeling of something stuck in the throat.

• Restricted Jaw Movement: Difficulty opening the jaw.

• Unexplained Weight Loss and Fatigue.

How to Detect Early Signs of Oral Cancer?

Early detection significantly increases the chances of successful treatment. Self-examination in front of a mirror to check for abnormal patches, swelling, or lumps in the lips, tongue, gums, and palate can be helpful. Noticing pain, bleeding, or sensitivity while brushing teeth or eating is also important. If any of these symptoms persist for more than two weeks, a dentist or an ENT specialist should be consulted.

Causes and Risk Factors of Oral Cancer

Oral cancer is primarily caused by tobacco and alcohol use, HPV infections, sun exposure, and genetic factors. Adopting a healthy lifestyle can help reduce these risks.

Tabaco y consumo de tabaco

Smoking and chewing tobacco are the leading causes of oral cancer. Carcinogenic substances in tobacco directly damage oral tissues and lead to cell mutations. Pipe and cigar smoking also increase the risk significantly.

Effects of Alcohol Consumption

Excessive alcohol consumption damages oral tissues, increasing the risk of cancer. The combined use of alcohol and tobacco raises the risk by up to 30 times. Heavy alcohol consumption weakens the immune system, making the body more vulnerable to cancer cells.

HPV and Viral Infections

The Human Papillomavirus (HPV) is a major contributing factor in many oral cancer cases. HPV-16 and HPV-18 strains are particularly linked to oral cancer. Persistent oral lesions could indicate HPV infection. Getting the HPV vaccine significantly reduces the risk.

Poor Nutrition and Weak Immune System

A diet low in fruits and vegetables can increase the risk of oral cancer. Consuming antioxidant-rich foods helps protect cells from DNA damage. Individuals with vitamin A, C, and E deficiencies are more prone to oral cancer. A balanced and healthy diet strengthens the immune system and prevents cancer cell development.

How is Oral Cancer Diagnosed?

Oral cancer often starts with subtle changes that may go unnoticed. If one or more of the following symptoms persist for over two weeks, a dentist or doctor should be consulted:

• Non-healing sores and bleeding

• Red or white patches in the mouth

• Pain while chewing or swallowing

• Numbness in the tongue or gums

• Hoarseness or speech changes

• Swelling or hard lumps in the jaw or throat

• Unexplained weight loss and chronic bad breath Dentists can identify early signs of oral cancer during routine checkups and recommend further examinations if necessary.

Treatment Methods for Oral Cancer

The treatment approach for oral cancer depends on the stage, location, and overall health of the patient. Early detection significantly increases treatment success. Surgery is the most common treatment method, aiming to remove cancerous tissue and prevent further spread.

Common surgical procedures include:

• Tumor Resection: Complete removal of cancerous tissue.

• Glossectomy: Partial or total removal of the tongue if affected.

• Mandibulectomy: Partial removal of the jawbone if the cancer has spread.

• Lymph Node Removal: If cancer has reached the lymph nodes, they may need to be removed.

• Reconstructive Surgery: Used to restore function and aesthetics after extensive tissue removal.

Radiotherapy uses high-energy X-rays to destroy cancer cells. It is employed to eliminate small tumors in early stages, prevent recurrence after surgery, or slow cancer progression.

Chemotherapy involves the use of drugs to kill or stop the growth of cancer cells. It is generally used for advanced cases or when cancer has spread to other organs.

Immunotherapy strengthens the immune system to help fight cancer cells. This method has shown promising results, especially in advanced oral cancer cases.

Prevention Methods for Oral Cancer

• Quit smoking and tobacco use: Reducing or quitting tobacco significantly lowers the risk.

• Limit alcohol consumption: Excessive alcohol damages oral tissues and increases cancer risk.

• Maintain a healthy diet: Eating a diet rich in fruits and vegetables strengthens immune defense against cancer.

• Practice good oral hygiene: Regular brushing, flossing, and using mouthwash help reduce bacterial buildup.

• Use sun protection for lips: Apply lip balm with SPF and wear a hat when exposed to the sun.

• Get vaccinated for HPV: The HPV vaccine significantly lowers the risk of HPV-related oral cancers.

• Regular dental check-ups: Early detection of suspicious lesions through routine dental visits enhances survival rates.
