Common Signs of Oral Cancer You Should Never Ignore – Causes, Symptoms, Care & Treatment

Abstract

Oral cancer is the second most common cancer affecting the head and neck region. It can develop in any part of the oral cavity, including the tongue, lips, cheeks, floor of the mouth, and palate. It may also spread to the pharynx, throat, and tonsils. Oral cancer presents with a variety of signs and symptoms and can cause significant discomfort while talking, eating, or swallowing. The disease progresses through different stages, and many people remain undiagnosed until it reaches an advanced stage. A healthcare provider confirms the diagnosis through an oral examination and diagnostic tests such as a biopsy. Treatment options include surgery, radiotherapy, or chemotherapy, depending on the stage and type of cancer, as well as the patient’s overall health.

Common Signs of Oral Cancer

Statistics for Oral Cancer

  • In India, there are around 70000-77000 new cases of oral cancers each year.
  • The death rate with oral cancer is most common in India with 52000 cancer patients dying annually.
  • The average age of oral cancer prevalence is 64 years and 20% of the cases are under 55 years of age.
  • Oral cancer accounts for about 5% of all cancers worldwide.
  • Every hour, about five people die from oral cancer, reflecting its high mortality rate.

Introduction

Oral cancer is a broad term used to describe cancers that affect different parts of the oral cavity. Early signs may resemble common conditions such as white patches, mouth ulcers, or bleeding gums, making them easy to overlook. Oral cancer has the potential to spread to nearby structures in the head and neck region. It is more common in men than in women. The disease may also affect the oropharynx, including the palate, the posterior part of the tongue, and the middle part of the throat.

Different anatomical sites of Oral Cancer

  • Gums
  • Lips
  • Floor of mouth
  • Anterior part of tongue
  • Cheeks
  • Area behind the third molar tooth.

Types of Oral Cancer

There are several types of oral cancer based upon their location in the mouth. These are:

  • Squamous cell carcinoma – It affects some parts of the tongue, buccal mucosa, gingiva and lower lip.
  • Lymphoma – It affects the posterior area of the oral cavity, tonsillar region and base of the tongue.
  • Verrucous carcinoma – It affects the inner lining of cheeks, gingiva or the tongue.
  • Mucoepidermoid carcinoma – It is a tumor of the parotid salivary gland.
  • Adenoid cystic carcinoma – It is a salivary gland tumor
  • Melanoma – It affects the hard palate and upper gingiva.
  • Sarcoma – It affects the jaw bone and the buccal soft tissues.

Pathophysiology and risk factors of Oral Cancer

Grow and multiply uncontrollably. Most oral cancers arise from squamous cells, which are thin, flat cells that line the lips and the inside of the oral cavity. Changes or mutations in the DNA of these cells disrupt the normal regulation of cell growth and programmed cell death. As a result, abnormal cells continue to multiply while healthy cells die. Over time, these abnormal cells accumulate to form a mass known as a tumor. The tumor can invade nearby healthy tissues, and some cancer cells may eventually spread to distant parts of the body through a process known as metastasis.

Since there is no single cause of oral cancer, several risk factors contribute to its development. These include:

  • Alcohol: Excessive and frequent alcohol consumption increases the risk of oral cancer.
  • Smoking and tobacco use: Tobacco products such as cigarettes, cigars, pipes, chewing tobacco, betel nut, and snuff significantly increase the risk.
  • Ultraviolet (UV) radiation: Prolonged exposure to sunlight or tanning lamps increases the risk of lip cancer.
  • Human papillomavirus (HPV): HPV is transmitted through sexual contact. Although it often causes no symptoms, certain strains can alter cellular DNA and contribute to oral cancer.
  • Weak immunity and chronic stress: A weakened immune system due to medications, organ transplantation, HIV infection, or chronic stress may increase susceptibility to oral cancer.
  • Age: People aged 65–69 years are at a higher risk of developing oral cancer.
  • Family history: Individuals with a family history of cancer may have an increased risk because of shared genetic, environmental, and lifestyle factors.

Seven Common Signs of Oral Cancer that Should Not be Ignored

Recognizing the early signs of oral cancer can improve the chances of successful treatment. Early-stage oral cancer is often highly treatable. Therefore, it is important to seek medical evaluation if any of the following symptoms persist:

  • Persistent mouth sores: Mouth sores caused by accidental cheek biting, tongue biting, braces, or minor infections usually heal within one to two weeks. However, sores that persist for more than 14 days should be evaluated, as they may indicate a precancerous or cancerous condition. Initially, these sores may be painless but can later become painful or bleed.
  • Lumps in the mouth and neck: Any unexplained lump or thickened tissue in the mouth or neck that persists without an obvious cause should not be ignored. These lumps may be noticed while brushing, speaking, or chewing.
  • Red or white patches: White patches (leukoplakia) and red patches (erythroplakia) result from abnormal cell growth and are considered precancerous lesions. Red patches are particularly concerning because they have a higher likelihood of becoming cancerous. Mixed red-and-white patches may also occur.
  • Difficulty in jaw movements and swallowing: Progressive difficulty in opening the mouth or swallowing may indicate oral cancer. Pain while swallowing food or liquids and unintentional weight loss due to reduced food intake are common associated symptoms. Jaw stiffness may also contribute to temporomandibular joint (TMJ) disorders.
  • Persistent pain in ear:  Long-lasting ear pain without an obvious ear infection may be referred to as pain from a tumor in the oral cavity or throat and should be medically evaluated.
  • Changes in voice or hoarseness: Persistent hoarseness, a strained or raspy voice, or difficulty speaking should not be ignored, particularly if accompanied by mouth sores, difficulty swallowing, or unexplained weight loss.
  • Bleeding in the mouth: Unexplained bleeding from the mouth, especially while brushing the teeth or blood in the saliva without an obvious cause, requires prompt medical evaluation.

Diagnosis and staging of Oral Cancer

Anyone experiencing symptoms suggestive of oral cancer should consult a healthcare provider for evaluation. Early diagnosis can prevent disease progression and improve treatment outcomes. Several diagnostic tests are used to confirm the diagnosis:

  • Incisional biopsy: The doctor removes a small sample of tissue for examination. If the suspicious area appears concerning, they may also remove the entire lesion along with a small margin of surrounding healthy tissue.
  • Oral brush biopsy: Cells are collected by gently brushing the affected area with a specialized brush.
  • Fine-needle aspiration (FNA): A thin, hollow needle attached to a special syringe is used to collect a sample of cells from a lump in the neck or an enlarged lymph node for laboratory examination.
  • Endoscopy: The doctor examines the throat using a flexible tube fitted with a tiny camera. If any abnormal or suspicious areas are identified, tissue samples may be collected for further analysis.
  • HPV testing: In cancers involving the throat or the back of the tongue, tumor cells may be tested for HPV, as the presence of the virus influences cancer staging.
  • Imaging tests (CT, MRI, and PET/CT): CT and MRI scans help determine the size and location of the tumor and assess whether the cancer has spread to nearby lymph nodes or other parts of the body.

Staging of Oral Cancer

Oral cancers are classified on the basis of size of tumor, lymph node involvement and its spread. TNM staging is done for this purpose. T denotes tumor size, N denotes nodal involvement and M denotes metastasis.

T = Primary tumor

  • Tx – Tumor cannot be detected
  • Tis – Carcinoma in-situ
  • T1 – Size of tumor is less than or equal to 2cm
  • T2 – Size of tumor is more than 2cm
  • T3 – Size of tumor is greater than 2cm or equal to 4cm
  • T4 -Size of tumor is greater than 4cm

N = Regional lymph node

  • NX– Nodes cannot be detected
  • N0– No spread to lymph nodes.
  • N1– Spread to one lymph node on the same side, with size 3 cm or less
  • N2– Spread to one large or several  lymph nodes on the same or opposite side
  • N3– Spread to a node larger than 6 cm, or there is multi-node involvement

M = Distant metastasis

  • M0 – No spread
  • M1 – Spread to other parts of body

There are different stages of oral cancer which are as follows:

  • Stage 0 – Carcinoma in-situ : Tis, N0, M0
  • Stage 1 – T1, N0, M0
  • Stage 2 – T2, N0, M0
  • Stage 3 – T3, N0, M0 or T1/T2/T3, N1, M0
  • Stage 4a – T4a, (N0, N1), M0 or (T1, T2, T3, T4a), N2, M0
  • Stage 4b – (Any T), N3, M0 or T4b, (Any N), M0
  • Stage 4c – (Any T), (Any N), M1

Conclusion

Oral cancer is a serious but largely preventable disease that requires early recognition and timely treatment. The main causes include tobacco, alcohol, HPV infection, and long-term sun exposure. Diagnosis is confirmed through clinical examination, biopsy, and imaging, while staging helps determine the extent of the disease and guides treatment planning. Early diagnosis greatly improves prognosis and survival. Raising awareness, reducing risk factors, and encouraging regular oral examinations are essential for improving survival and quality of life.

Can Vitamin Deficiency Affect Your Teeth and Gums? Symptoms, Signs & Causes

Abstract

Vitamin deficiencies affect oral health because the mouth is often one of the first parts of the body where nutritional deficiencies become evident. These deficiencies can manifest with various symptoms, such as bleeding gums, bad breath, inflammation, mouth ulcers, or even infections in the oral cavity. The enamel layer may weaken, and the gums often become inflamed due to impaired immune function and reduced tissue repair. The health of the mouth is closely linked to overall health. Understanding how vitamin deficiencies affect oral health is essential for planning appropriate treatment, seeking timely medical care, and receiving proper nutritional counselling.

Can Vitamin Deficiency Affect Your Teeth and Gums?

Statistics for Vitamin Deficiency and Oral Health

  • Children with vitamin deficiencies may have a higher risk of developing dental caries.
  • Vitamin B12 deficiency has been associated with an increased prevalence of gum disease and recurrent mouth ulcers.
  • Deficiency of B-complex vitamins may increase the risk of angular cheilitis (cracking at the corners of the mouth) and glossitis (inflammation of the tongue).
  • People with folate and vitamin B12 deficiencies are at a higher risk of developing recurrent aphthous ulcers.

Introduction

Vitamins are essential organic nutrients required by the body in small amounts to support growth, development, wound healing, healthy bones and teeth, immunity, and numerous other biological functions. There are 13 essential vitamins required for normal body functions. Most vitamins cannot be synthesised in sufficient amounts by the body and therefore must be obtained through the diet. However, vitamin D can be synthesised in the skin following exposure to sunlight, while small amounts of vitamin K and biotin are produced by intestinal bacteria. Different vitamins perform different biochemical roles in the body.

Vitamins are classified into two groups based on their solubility:

  • Water-soluble vitamins: These are not stored in significant amounts in the body, and excess amounts are excreted through the urine. These include the B-complex vitamins and vitamin C.
  • Fat-soluble vitamins: These are stored in the body’s fat tissues and liver. These include vitamins A, D, E, and K. These vitamins are naturally present in a variety of plant- and animal-based foods and play an important role in human growth, development, and overall health. The body absorbs these vitamins from food, while unabsorbed nutrients are eliminated through the faeces.

Vitamins and Their Food Sources

  • Vitamin A: Sweet potatoes, spinach, eggs, pumpkin, carrots, liver, and beef
  • Vitamin E: Green leafy vegetables, nuts, seeds, vegetable oils, and fortified cereals
  • Vitamin D: Sunlight exposure, fortified milk and dairy products, fatty fish, egg yolks, and fortified cereals
  • Vitamin K: Dark green leafy vegetables, beet greens, turnip greens, broccoli, and cabbage
  • Vitamin C: Oranges, lemons, amla, grapefruit, strawberries, guava, and bell peppers
  • Vitamin B1 (Thiamine): Whole grains, pork, legumes, seeds, and fortified cereals
  • Vitamin B2 (Riboflavin): Dairy products, eggs, lean meat, whole grains, and green leafy vegetables
  • Vitamin B3 (Niacin): Fish, poultry, whole grains, mushrooms, peanuts, and legumes
  • Vitamin B5 (Pantothenic Acid): Broccoli, chicken, legumes, mushrooms, avocados, and whole grains
  • Vitamin B6 (Pyridoxine): Poultry, fish, potatoes, bananas, soy products, chickpeas, and fortified cereals
  • Vitamin B7 (Biotin): Egg yolks, nuts, seeds, meat, liver, legumes, and some fruits
  • Vitamin B9 (Folate/Folic Acid): Green leafy vegetables, legumes, citrus fruits, and fortified cereals
  • Vitamin B12: Meat, fish, eggs, dairy products, poultry, and fortified cereals

Vitamins and their Functions and Dosage

Consuming a balanced diet rich in vegetables, fruits, dairy products, whole grains, and other nutritious foods provides the essential vitamins required for normal body functions. In most healthy individuals, a balanced diet is sufficient to meet daily vitamin requirements. Vitamin supplements should only be taken when recommended by a healthcare professional or when a deficiency has been diagnosed. Excessive intake of certain vitamins may lead to toxicity.

The functions of different vitamins are:

Vitamin A

  • Dosage:Women = 700 mcg/day, Men = 900 mcg/day

  • Helps prevent bleeding disorders, including haemorrhagic disease of the newborn (HDN).

How Vitamin Deficiency Affects the Teeth and the Gums? Signs You Should Know

Eating a balanced and healthy diet helps provide the essential vitamins required for the proper functioning of the body. In most healthy individuals, a well-balanced diet is sufficient to meet daily vitamin requirements. However, vitamin supplements may be recommended by a healthcare professional when a deficiency is diagnosed or when dietary intake is inadequate. Various oral manifestations can occur due to vitamin deficiencies, as different vitamins support different functions in the oral cavity. The signs and symptoms vary depending on the specific vitamin deficiency. The common oral signs and symptoms associated with different vitamin deficiencies are as follows:

  • Red, swollen and bleeding gums: This is one of the most common and earliest signs of certain vitamin deficiencies. Vitamin C deficiency can lead to gum bleeding and, in severe cases, a condition known as scurvy. Vitamin C is essential for collagen synthesis and tissue repair; therefore, its deficiency weakens the gums and impairs the body’s immune response. Vitamin K deficiency may also contribute to prolonged gum bleeding due to its important role in blood clotting. As a result, the gums may become swollen, inflamed, tender, and bleed even during gentle brushing.
  • Mouth sores and ulcers: Canker sores and other ulcerative lesions in the mouth may indicate deficiencies of B-complex vitamins, particularly vitamin B12 and folate (vitamin B9). These vitamins play an important role in cellular repair, DNA synthesis, and regeneration of the oral tissues.
  • Tooth decay and sensitivity: Vitamin D plays a crucial role in the absorption of calcium and phosphorus, which are essential for healthy teeth. Deficiency of vitamin D may weaken enamel mineralisation, making the teeth more sensitive and increasing the risk of tooth decay.
  • Burning mouth and tongue: A burning or tingling sensation in the mouth, along with soreness, redness, or inflammation of the tongue (glossitis), may be associated with deficiencies of vitamin B12, vitamin B6, and folate.
  • Angular cheilitis: Angular cheilitis is characterised by inflammation at the corners of the mouth. The lips may become cracked, red, sore, and painful. Deficiency of vitamin B2 (riboflavin) is one of the common nutritional causes of this condition.
  • Tooth discolouration: Teeth may gradually lose their natural appearance due to weakened enamel. Vitamin A deficiency may interfere with normal enamel development and maintenance, while vitamin D deficiency can weaken enamel mineralisation, making the teeth more susceptible to discolouration and dental decay over time.
  • Xerostomia: Dry mouth may be associated with vitamin A deficiency, as vitamin A helps maintain healthy oral mucosal tissues. However, xerostomia can also occur due to medications, dehydration, diabetes, autoimmune disorders, or radiation therapy. Reduced salivary flow may increase the risk of tooth decay, oral infections, and difficulty in speaking or swallowing.

Nutritional counselling should be provided to patients to help them understand the relationship between vitamins and oral health. They should be guided regarding appropriate dietary intake and healthy eating habits to prevent nutritional deficiencies. Dentists may collaborate with dietitians or nutritionists to provide a multidisciplinary approach to patient care. Self-supplementation should be avoided, and vitamin supplements should only be taken under the guidance of a qualified healthcare professional. Healthcare providers should also emphasise the importance of a balanced diet and adequate nutrient intake for maintaining good oral and overall health.

Conclusion

Proper intake of a balanced diet and adequate nutrition is essential for maintaining healthy bodily functions. Vitamins are micronutrients required by the body in small amounts that support growth, development, and various physiological functions. They are obtained from a variety of plant- and animal-based food sources. Although some vitamins can be synthesised in limited amounts by the body, most must be obtained through the diet. Vitamin deficiencies can affect both general and oral health and may lead to various oral manifestations. Therefore, maintaining a balanced diet with adequate vitamin intake is essential for preserving overall health and promoting healthy teeth and gums.
