Oral Cancers: Symptoms, Types, Stages, Treatment and more

Oral cancers, also known as mouth cancers, are a group of malignant tumors that can develop in various parts of the mouth, including the lips, tongue, gums, cheeks, and the roof or floor of the mouth. These cancers typically start as abnormal cell growth, often fueled by factors like tobacco and alcohol use, human papillomavirus (HPV) infection, and a diet lacking in fruits and vegetables. Early detection is crucial, as oral cancers can be aggressive and have a high potential for spreading to other parts of the body if not treated promptly.

Symptoms may include persistent mouth sores, pain, difficulty in swallowing or speaking, and changes in the appearance of the mouth or throat. Regular dental check-ups and a healthy lifestyle are essential for prevention, while prompt medical attention can significantly improve the prognosis and quality of life for those affected by oral cancers.

Types of oral cancers

Oral cancer refers to cancers that develop in the mouth, including the lips, tongue, cheeks, gums, and palate. There are several types of oral cancers, with squamous cell carcinoma being the most common. Here are some of the primary types of oral cancers:

Squamous Cell Carcinoma: This is the most common type of oral cancer, and it typically begins in the thin, flat cells lining the oral cavity. Squamous cell carcinoma accounts for the majority of oral cancer cases.

Verrucous Carcinoma: This is a slow-growing type of squamous cell carcinoma that is often associated with tobacco use. It tends to be less aggressive than other types of oral cancer and has a better prognosis.

Adenocarcinoma: Adenocarcinomas develop in the salivary glands, which are located in and around the oral cavity. These cancers can occur in the major or minor salivary glands and can vary in their aggressiveness.

Mucoepidermoid Carcinoma: This is another type of cancer that affects the salivary glands. Mucoepidermoid carcinomas can be low-grade or high-grade, with the latter being more aggressive.

Adenoid Cystic Carcinoma: This is a rare and slow-growing cancer that primarily occurs in the minor salivary glands and can be challenging to treat due to its tendency to spread along nerve pathways.

Lymphomas: Lymphomas can develop in the oral cavity, particularly in the tonsils and base of the tongue. Non-Hodgkin lymphoma is a common type that can affect these areas.

Melanoma: Oral melanoma develops from pigment-producing cells called melanocytes and can occur on the lips, tongue, or inside the mouth. It is relatively rare but can be aggressive.

Sarcomas: Sarcomas are a rare type of oral cancer that originate in the connective tissues, muscles, or bones of the oral cavity. Examples include osteosarcoma and rhabdomyosarcoma.

What are symptoms of oral cancer?

Oral cancer, also known as mouth cancer, can present various symptoms, although it’s important to note that these symptoms can also be caused by other, less serious conditions. If you experience any of the following symptoms persistently, it’s essential to consult a healthcare professional or dentist for a proper evaluation. Common symptoms of oral cancer include:

Persistent mouth sores: Sores in the mouth that don’t heal within a few weeks can be a cause for concern.

Red or white patches: Any unexplained red or white patches in the mouth, on the tongue, or on the lips should be examined.

Lump or thickening: A lump, bump, or thickening in the mouth, neck, or throat may be indicative of oral cancer.

Sore throat: A chronic sore throat or a feeling of something stuck in the throat can be a symptom.

Difficulty swallowing or chewing: Problems with swallowing, chewing, or moving the tongue or jaw can be warning signs.

Pain or discomfort: Persistent pain in the mouth or throat, or ear pain not related to an ear infection, can be concerning.

Changes in voice: Hoarseness or changes in the voice that last for an extended period should be evaluated.

Numbness or tingling: Numbness, tingling, or loss of feeling in the mouth or lips can be associated with oral cancer.

Unexplained bleeding: Unexplained bleeding in the mouth or throat, or blood in saliva, should not be ignored.

Weight loss: Unintended weight loss without changes in diet or exercise can be a sign of oral cancer.

How is oral cancer diagnosed?

Oral cancer is typically diagnosed through a combination of clinical examinations and diagnostic tests. The diagnostic process for oral cancer may include the following steps:

Medical History and Clinical Examination

The first step in diagnosing oral cancer involves a detailed medical history and a physical examination of the mouth and throat. The healthcare provider will ask about any symptoms you may be experiencing, such as persistent sores, lumps, or changes in your mouth, throat, or neck. They will also check for risk factors, such as tobacco and alcohol use.


If suspicious lesions or growths are found during the clinical examination, a biopsy is usually the next step. During a biopsy, a small sample of tissue is removed from the suspected area for laboratory analysis. There are different types of biopsies, including:

  • Incisional biopsy: A small piece of the suspicious tissue is removed.
  • Excisional biopsy: The entire growth or lesion is removed.
  • Fine needle aspiration (FNA): A thin, hollow needle is used to extract a sample of cells or fluid from a lump or lymph node.

Imaging Studies

Imaging tests may be used to determine the extent of the cancer, its location, and whether it has spread to nearby structures or lymph nodes. Common imaging studies include:

  • X-rays: These can provide a broad overview of the oral cavity and surrounding structures.
  • CT (computed tomography) scan: This provides detailed cross-sectional images of the mouth, throat, and neck.
  • MRI (magnetic resonance imaging): It can offer more detailed images without radiation exposure.
  • PET (positron emission tomography) scan: This is used to check for the spread of cancer to other parts of the body.


  • An endoscope, a thin, flexible tube with a camera at its tip, may be used to examine the inside of the mouth, throat, and esophagus in detail. This procedure is often called an endoscopy or a panendoscopy.


  • Once oral cancer is confirmed, it is important to determine the stage of the cancer, which indicates the extent of the disease. Staging helps guide treatment decisions. Staging is based on factors such as the size of the tumor, its depth of invasion, lymph node involvement, and whether it has metastasized (spread to distant parts of the body).

Biological Tests

  • Some molecular and genetic tests may be used to better understand the specific characteristics of the cancer. This information can guide treatment choices and predict prognosis.

Dental Evaluation

  • A thorough dental evaluation may also be performed to assess the overall oral health of the patient, as good oral hygiene is essential during cancer treatment.

What are the stages of oral cancer?

Oral cancer, also known as mouth cancer or oral cavity cancer, can develop in different stages. The stages of oral cancer are typically determined using the TNM staging system, which stands for Tumor, Node, and Metastasis. The stages range from 0 to IV, with subcategories for more detailed classification. Here’s an overview of the stages:

  1. Stage 0 (Carcinoma in situ): This is the earliest stage, where abnormal cells are found only in the innermost layer of the oral mucosa. It’s often called “pre-cancer” because it hasn’t invaded deeper tissues.
  2. Stage I: At this stage, the tumor is small, usually less than 2 centimeters (about 0.8 inches) in size and hasn’t spread to nearby lymph nodes or other tissues.
  3. Stage II: The tumor is larger than in Stage I but still hasn’t spread to nearby lymph nodes or other tissues.
  4. Stage III: In this stage, the tumor is larger, may have spread to nearby lymph nodes, or has invaded deeper tissues within the oral cavity.
  5. Stage IVA: The tumor may be any size, but it has not spread to distant parts of the body. It may have spread to nearby lymph nodes and/or invaded surrounding tissues.
  6. Stage IVB: This stage involves a larger primary tumor that may have spread to lymph nodes or other tissues, or it has invaded nearby structures such as the bones of the jaw or skull.
  7. Stage IVC: This is the most advanced stage, where the cancer has spread (metastasized) to distant parts of the body, such as the lungs or liver.

How is oral cancer treated?

The treatment of oral cancer typically depends on the stage of the cancer, its location, and the overall health of the patient. Treatment options for oral cancer may include one or more of the following:


Surgical removal of the tumor and nearby affected tissues is a common treatment for oral cancer. This may involve removing part or all of the affected tissue, lymph nodes, and in some cases, reconstructive surgery to restore appearance and function.

Radiation Therapy

High-energy X-rays or other radiation sources can be used to kill cancer cells or shrink tumors. It may be used as the primary treatment or in combination with surgery or chemotherapy.


Medications are used to kill cancer cells or stop their growth. Chemotherapy can be administered orally or intravenously, and it is often used in combination with other treatments.

Targeted Therapy

Targeted drugs are designed to specifically target cancer cells while sparing healthy cells. These treatments are often used for advanced cases or in combination with other therapies.


This treatment stimulates the patient’s own immune system to fight the cancer. Immunotherapy drugs can be used in some cases of oral cancer.

Palliative Care

For advanced cases where a cure may not be possible, palliative care focuses on relieving symptoms and improving the patient’s quality of life.

The specific treatment plan is developed by a medical team that includes surgeons, oncologists, radiation oncologists, and other specialists. The treatment approach may involve a combination of these therapies, known as multimodal therapy. Additionally, supportive care and rehabilitation may be necessary to manage side effects and help patients regain normal function, particularly in cases where surgical removal of tissue affects speech, swallowing, and appearance.

Reconstruction and rehabilitation after oral cancer treatment

Reconstruction and rehabilitation after oral cancer treatment are crucial aspects of a patient’s recovery process. Treatment for oral cancer often involves surgery, radiation therapy, and/or chemotherapy, which can result in significant changes to a person’s appearance and function. The goal of reconstruction and rehabilitation is to restore a patient’s oral and facial function, as well as improve their quality of life. Here are some key aspects of this process:

Multidisciplinary Team

The management of oral cancer typically involves a multidisciplinary team, including oral surgeons, plastic surgeons, oncologists, dentists, speech therapists, and prosthodontists. This team works together to create a comprehensive treatment plan that addresses both the cancer and the resulting functional and cosmetic issues.

Surgical Reconstruction

Surgical reconstruction may be necessary to repair defects caused by cancer removal. This can involve various procedures, such as tissue grafts, free flaps (tissue transferred from another part of the body), and microvascular surgery. The goal is to restore the patient’s ability to eat, speak, and swallow comfortably.

Dental Rehabilitation

Dental rehabilitation plays a crucial role in restoring oral function. This may include dental implants, dentures, or other dental prostheses. Dental rehabilitation can help patients regain the ability to chew and speak effectively.

Speech and Swallowing Therapy

Many oral cancer patients experience speech and swallowing difficulties following treatment. Speech therapists can work with patients to improve articulation and swallowing function through exercises and techniques.

Prosthetic Devices

Custom-made prosthetic devices, such as obturators (for palate defects) and tracheoesophageal speech devices, can aid in restoring function and speech. These devices are typically designed to fit the individual patient’s needs.

Psychosocial Support

Coping with the physical and emotional challenges of oral cancer treatment can be overwhelming. Patients may benefit from psychological support and counseling to address issues related to body image, self-esteem, and overall well-being.

Nutritional Support

Maintaining proper nutrition is vital for healing and recovery. Nutritionists and dietitians can work with patients to develop a diet plan that accommodates their specific needs and any swallowing difficulties.

Follow-Up Care

Regular follow-up appointments with the medical team are essential to monitor the patient’s progress, manage any complications, and make necessary adjustments to the treatment plan.

Support Groups

Joining support groups and connecting with other oral cancer survivors can be immensely helpful. Sharing experiences and coping strategies with others who have gone through a similar journey can provide emotional support.

The Bottom Line

Oral cancer is a serious and potentially life-threatening condition that demands proactive preventive measures, including regular dental check-ups, tobacco cessation, and responsible alcohol consumption. Early detection and timely intervention are critical for improving the prognosis and quality of life for those at risk.
