Carcinoma of the tongue, also known as tongue cancer, is a type of oral cancer that affects the tissues of the tongue. It typically originates in the squamous cells, which are the thin, flat cells lining the surface of the tongue. This form of cancer can develop anywhere on the tongue, including the front two-thirds (oral tongue) or at the base of the tongue (base of tongue cancer). In this detailed answer, we will explore the causes, symptoms, diagnosis, staging, treatment options, and prevention of carcinoma of the tongue.
Carcinoma of the tongue can be caused a variety of factors, with tobacco and alcohol use being the most common risk factors. Studies have shown that individuals who smoke or use smokeless tobacco products are at a higher risk of developing tongue cancer compared to non-smokers. Likewise, excessive alcohol consumption can increase the risk of tongue cancer, especially when combined with tobacco use. Other risk factors include a family history of oral cancer, poor oral hygiene, chronic irritation of the tongue, human papillomavirus (HPV) infection, and a weakened immune system.
Detecting carcinoma of the tongue in its early stages is crucial for successful treatment outcomes. However, the early symptoms of tongue cancer can be easily overlooked or mistaken for other less serious conditions. Common symptoms may include a persistent sore throat or pain in the tongue that does not improve, tongue ulcers that do not heal, a lump or thickening in the tongue, difficulty speaking or swallowing, red or white patches on the tongue, and persistent mouth or ear pain. These symptoms should not be ignored and warrant a visit to a healthcare professional for further evaluation.
To diagnose carcinoma of the tongue, a healthcare professional may start with a thorough physical examination of the mouth, tongue, and neck. This examination may include palpation of the tongue to detect any unusual lumps or masses. Additionally, a dentist or oral surgeon may perform a biopsy to collect a small sample of tissue from the affected area. This tissue sample is then sent to a laboratory for microscopic analysis to determine if cancer cells are present. Imaging tests such as CT scans, MRI scans, or PET scans may also be recommended to determine the extent and spread of the cancer.
Once diagnosed, carcinoma of the tongue is staged to determine the severity and spread of the cancer. The most commonly used staging system for tongue cancer is the TNM system, which considers the size of the tumor (T), the involvement of nearlymph nodes (N), and the presence of metastasis (M). Stages range from 0 to IV, with stage 0 indicating carcinoma in situ (cancer cells confined to the top layer of the tongue) and stage IV indicating advanced cancer that may have spread to distant sites in the body.
Treatment options for carcinoma of the tongue depend on the stage of the cancer, the overall health of the patient, and the preferences of the healthcare team and the patient. Common treatment modalities include surgery, radiation therapy, chemotherapy, or a combination of these approaches. Surgical removal of the tumor is often the primary treatment method for early-stage tongue cancer. Depending on the size and location of the tumor, partial or total removal of the tongue may be necessary. In some cases, reconstructive surgery may be performed to restore both appearance and function.
Radiation therapy uses high-energy rays to kill cancer cells and is often used as the primary treatment for advanced-stage tongue cancer or as an adjuvant therapy after surgery. Chemotherapy, on the other hand, utilizes drugs to kill cancer cells and may be administered prior to surgery to shrink tumors or after surgery to destroy any remaining cancer cells.
Preventing carcinoma of the tongue involves minimizing the risk factors associated with the disease. The most effective preventive measure is adopting a healthy lifestyle. Avoiding tobacco in all forms, including cigarettes, cigars, and smokeless tobacco products, significantly reduces the risk of developing tongue cancer. Similarly, limiting alcohol consumption to moderate levels (up to one drink per day for women and up to two drinks per day for men) can also help reduce the risk.
Maintaining good oral hygiene and regular dental check-ups are essential to detect any abnormalities in the mouth or tongue early on. Practicing safe sex and getting vaccinated against HPV can also play a role in preventing tongue cancer, as HPV has been associated with an increased risk of developing oral cancers.

Early detection is crucial, as symptoms can be easily overlooked. Diagnosis involves physical examinations, biopsies, and imaging tests.
