Add as a preferred source on Google

World Cancer Day is observed every year on 4 February to raise awareness of this chronic condition and encourage its early detection, prevention and treatment.

Tongue cancer is one of the types of head and neck cancer that begins in the tongue cells. According to a study, tongue cancer constitutes around 36.5 per cent of all oral cavity malignancies. [1]

The cancer is highly prevalent in males compared to females by a ratio of 1.7:1 and the mean age for the development of cancer is around 30.5 years.

In this article, we will discuss details on tongue cancer. Take a look.

Types Of Tongue Cancer

The tongue, along with the floor of the mouth and the lips, is one of the common subsites within the oral cavity. As the anterior two-thirds of the tongue is inside the oral cavity, the posterior or base of the tongue is considered a part of the oropharynx or the throat. [2]

This is why, when cancer in tongue cells occurs in the base or say from where the throat starts, it is considered to be a different cancer type in terms of prognosis and treatment.

Tongue cancer in the anterior parts of the tongue is called oral tongue cancer while at the posterior is called oropharyngeal cancer.

Tongue cancer has many stages and grades which represent how far and in what body areas cancer has spread. According to the American Joint Committee on Cancer, the TNM system is used to represent staging cancer of the head and neck, where T tells about the size of the tumour, N says whether cancer has spread to lymph nodes and M says whether the cancer is metastases or have a tendency to spread to nearby body areas. [3]

Causes And Risk Factors For Tongue Cancer

Tongue cancer is mainly caused due to environmental factors like chronic smoking habits and alcoholism.

Tobacco, used in the making of cigarettes, contain carcinogens or cancer-causing substances like polycyclic hydrocarbons and nitrosamines. On the other hand, when alcohol is consumed, it gets metabolised into acetaldehyde in the body that may cause alternations in the DNA. [4]

In some studies, Human papillomavirus (HPV) infection is also the main cause of tongue cancer, especially at the base of the tongue. [5]

Some of the other causes for the development of tongue cancer may include:

• Radiation exposure.
• Chronic chewing of betel leaves, which is common in Asia.
• Poor oral hygiene
• Immune-suppression conditions.

People with any form of oral or oropharyngeal cancer are at increased risk of tongue cancer.

Symptoms Of Tongue Cancer

Some of the common symptoms of tongue cancer may include:

• Lesions in the tongue.
• Weight-loss [6]
• Dysarthria (motor speech disorder).
• Odynophagia (painful swallowing).
• Persisting ulcer in the tongue.
• Numbness in the mouth
• Bleeding from the tongue without any cause.
• Sore throat.

Complications Of Tongue Cancer

Tongue cancer, if left untreated for longer can cause complications such as: [7]

• Speech problems, if cancer spreads to the base of the mouth.
• Excessive salivation
• Orocutaneous fistula
• Infection in the mouth.
• Tooth decay.
• Stiffness in the jaws.
• Burning sensation in the mouth.
• Trauma
• Nutritional deficiencies.

Diagnosis Of Tongue Cancer

Tongue cancer is often consumed with other conditions such as carcinoma in situ, leukoplakia, papilloma, lingual thyroid and dermoid cyst.

To diagnose tongue cancer, a medical expert may ask for personal habits like tobacco smoking or alcohol usage, along with a history of cancer in the family.

Some of the methods to diagnose tongue cancer may include:

• Positron emission tomography scans: It indicates a growing tumour in tongue cells.
• X-rays: To get a detailed view of the mouth and throat.
• Biopsy: To detect cancerous tissues.

Treatments Of Tongue Cancer

Some of the treatment methods for tongue cancer may include: [8]

• Chemotherapy: Using powerful drugs to kill cancerous cells.
• Radiotherapy: Using high radiation to kill cancer cells.
• Surgery: Removing the cancerous cells by surgically removing the affected area.
• Combinational therapy: It includes a combination of any or all of the aforementioned therapies.

To Conclude

Tongue cancer is life-threatening but is a highly curable type of cancer if detected at an early stage. If you have a habit of smoking, alcohol consumption or chewing betel leaves (paan) and have some of the aforementioned symptoms, consult a medical expert soon for proper diagnosis and treatment.
