Which of the following is the most significant risk factor for developing oral cancer?
Tobacco use
Prolonged sun exposure
Frequent mouthwash use
High-sugar diet
Tobacco use, including smoking and smokeless forms, is the single largest risk factor for oral cancer, accounting for a majority of cases. Carcinogens in tobacco induce mutations in the oral epithelium over time. Quitting reduces risk significantly. .
What is the most common anatomical site for oral squamous cell carcinoma?
Buccal mucosa
Hard palate
Lateral border of the tongue
Upper lip vermilion
The lateral border of the tongue is the most common site for oral squamous cell carcinoma due to high exposure to carcinogens and mechanical irritation. Early detection here is essential for improved outcomes. Other oral subsites are less frequently involved. .
Which of the following clinical signs is most suspicious for oral cancer?
Non-healing ulcer lasting more than two weeks
Painful vesicle that resolves quickly
Smooth red lesion for less than a week
White plaque that can be scraped off
A non-healing ulcer persisting beyond two weeks in the oral cavity is a red flag for possible malignancy and warrants biopsy. Healing ulcers from trauma typically resolve within days. Early biopsy improves treatment success. .
Leukoplakia in the mouth is characterized by:
White patches that cannot be scraped off
Vesicular lesions
Pigmented macules
Red patches that bleed easily
Leukoplakia presents as white, firmly adherent patches that cannot be removed by scraping and may harbor dysplasia or carcinoma. It is considered a premalignant lesion. Regular monitoring or biopsy is recommended. .
Infection with which virus is increasingly associated with oropharyngeal and some oral cancers?
Herpes simplex virus
Epstein-Barr virus
Human papillomavirus type 16
Cytomegalovirus
HPV type 16 is strongly linked to oropharyngeal squamous cell carcinomas and a subset of oral cancers. The virus integrates into host DNA, disrupting tumor suppressor pathways. Vaccination can reduce this risk. .
Heavy alcohol consumption contributes to oral cancer primarily by:
Depleting vitamin C levels
Acting synergistically with tobacco to damage oral mucosa
Causing HPV mutation
Inhibiting cell apoptosis directly
Alcohol has a synergistic effect with tobacco, enhancing mucosal permeability to carcinogens and promoting DNA damage. Together they sharply increase oral cancer risk. Alcohol alone is also an independent risk factor. .
Oral cancer incidence is highest in which age group?
Over age 60
Age 20-30
Under age 20
Age 30-50
Oral cancer is most common in adults over 60, reflecting cumulative exposure to risk factors over time. Incidence rises markedly after age 50. Younger patients may represent HPV-related disease subsets. .
The presence of enlarged cervical lymph nodes in an oral cancer patient most likely indicates:
Benign hyperplasia
Distant metastasis
Local invasion only
Regional metastasis
Enlarged cervical lymph nodes in oral cancer usually signal regional metastasis, as lymphatic spread is common. This finding upgrades staging and affects treatment planning. Fine-needle aspiration or biopsy confirms involvement. .
In TNM staging for oral cancer, a T3 classification means the primary tumor is:
2 - 4 cm in greatest dimension
2 cm or less in greatest dimension
Involving adjacent bone
More than 4 cm in greatest dimension
T3 denotes a primary tumor measuring over 4 cm in its greatest dimension. Size-based criteria help guide prognosis and therapy. Invasion into structures like bone is classified separately (T4). .
Which oral lesion has the highest risk of malignant transformation?
Traumatic ulcer
Erythroplakia
Oral lichen planus
Fordyce granules
Erythroplakia exhibits red velvety patches with a high rate of severe dysplasia or carcinoma on biopsy. Its malignant transformation risk exceeds that of leukoplakia. Immediate evaluation is essential. .
Moderate epithelial dysplasia in an oral biopsy indicates:
Changes confined to basal third
Atypical changes reaching the middle third of the epithelium
Full-thickness atypia
Carcinoma in situ
Moderate dysplasia is defined by atypical cells extending into the middle third of the epithelial thickness. It carries a higher risk of progression than mild dysplasia. Management often involves excision and close follow-up. .
The gold standard for definitive diagnosis of oral cancer is:
Clinical examination only
Brush cytology
MRI imaging
Incisional biopsy
An incisional biopsy provides tissue for histopathological examination, confirming invasive carcinoma. It allows assessment of dysplasia and tumor type. Other methods assist screening but are not definitive. .
Which imaging modality is most sensitive for detecting bone invasion in oral cancer?
CT scan
Panoramic radiograph
Ultrasound
PET scan
CT scans provide high-resolution images of cortical bone and can detect early bone invasion by tumor. This influences surgical planning. MRI is superior for soft tissue but less sensitive for bone detail. .
A clear surgical margin in oral cancer surgery refers to:
No tumor cells at the inked cut edge
Tumor depth less than 5 mm
Tumor cells present in lymph nodes
Tumor confined within 1 cm
A clear margin means that no cancer cells are found at the resection boundary when inked by the pathologist. It reduces local recurrence risk. Close margins may require further resection or adjuvant therapy. .
The concept of field cancerization in oral cancer explains:
Viral spread of HPV through saliva
Multiple primary tumors arise in a large area of epithelium exposed to carcinogens
Bone marrow involvement by tumor cells
Metastasis from a single primary lesion
Field cancerization describes genetically altered mucosal fields predisposed to multiple malignant lesions due to widespread carcinogen exposure. This accounts for synchronous and metachronous tumors. Surveillance of the entire field is important. .
EGFR overexpression in oral cancer can be targeted by therapies such as:
Corticosteroids
Platinum-based chemotherapy
Nonsteroidal anti-inflammatory drugs
Tyrosine kinase inhibitors
Tyrosine kinase inhibitors like erlotinib block EGFR signaling pathways when overexpressed in oral cancers. Targeting EGFR can inhibit proliferation and improve outcomes. Monoclonal antibodies are another EGFR approach. .
Sentinel lymph node biopsy in oral cancer is primarily used to:
Identify the first draining node to detect micrometastases
Measure tumor size radiologically
Deliver localized radiation
Remove all cervical lymph nodes
Sentinel lymph node biopsy maps and samples the first nodal basin at risk, detecting micrometastases with less morbidity than elective neck dissection. It guides the need for further neck treatment. .
Which salivary biomarker shows promise for early detection of oral cancer?
Serum albumin
Interleukin-8
Hemoglobin
C-reactive protein
Salivary IL-8 levels are often elevated in early oral cancer and dysplasia patients, making it a promising non-invasive biomarker. Research suggests IL-8 correlates with disease severity. Validation is ongoing. .
Photodynamic therapy for oral cancer works by:
Freezing malignant cells
Using high-frequency ultrasound to ablate tissue
Delivering beta radiation to tumors
Activating a photosensitizer to produce reactive oxygen species
Photodynamic therapy uses a photosensitizer drug that accumulates in tumor cells, then light activation generates reactive oxygen species that destroy malignant tissue. It minimizes damage to surrounding structures. It's under clinical investigation for oral lesions. .
Cyclin D1 gene amplification in oral cancer is associated with:
Reduced metastatic potential
Enhanced immune response
Poor prognosis and more aggressive behavior
Better response to radiation
Cyclin D1 overexpression from gene amplification drives cell cycle progression and is linked to aggressive tumor phenotypes and poorer outcomes in oral cancer. It is a potential prognostic marker. .
HPV-positive oral cancers generally have:
Better survival and response to therapy
Higher local recurrence rates
Similar prognosis to HPV-negative tumors
Worse survival than HPV-negative cases
HPV-positive oral and oropharyngeal cancers typically show improved survival and treatment response compared to HPV-negative tumors, partly due to distinct molecular profiles. De-escalation trials are exploring treatment reduction. .
Fluorescence visualization devices like VELscope aid in oral cancer screening by:
Emitting blue light to highlight abnormal mucosal tissue
Detecting HPV DNA in saliva
Providing 3D imaging of lesions
Measuring tissue stiffness
VELscope emits blue excitation light that causes healthy tissue to fluoresce green, while dysplastic or cancerous areas appear dark, helping detect subclinical lesions. It's an adjunct to visual exam, not a substitute for biopsy. .
Nivolumab, a PD-1 inhibitor used in advanced oral cancer, works by:
Delivering targeted radiation to malignant tissue
Inhibiting DNA synthesis directly in tumor cells
Blocking an immune checkpoint to enhance T-cell activity against tumor cells
Neutralizing tumor necrosis factor alpha
Nivolumab binds the PD-1 receptor on T cells, preventing engagement with PD-L1 on tumor cells and thereby reactivating immune-mediated tumor destruction. It has shown survival benefits in advanced head and neck cancers. .
NOTCH1 mutations in oral cancer are implicated in:
Increased programmed cell death
Decreased angiogenesis
Enhanced DNA repair capacity
Dysregulation of cellular differentiation and proliferation
NOTCH1 plays a critical role in regulating cell fate; loss-of-function mutations lead to disrupted differentiation and uncontrolled proliferation in oral epithelium. Such mutations are common in oral squamous cell carcinomas. .
Cancer-associated fibroblasts in the tumor microenvironment contribute to oral cancer progression by:
Enhancing saliva production to dilute carcinogens
Blocking new blood vessel formation
Remodeling the extracellular matrix and promoting tumor invasion
Directly killing tumor cells
Cancer-associated fibroblasts secrete proteases and growth factors that remodel extracellular matrix, facilitating invasion and metastasis of oral cancer cells. They also modulate immune responses and angiogenesis. Targeting them is an emerging therapeutic strategy. .

Cheat Sheet

  1. Persistent ulcers lasting beyond two weeks -

    One of the most common early signs of oral cancer is a sore or ulcer on the tongue, gums, or inner cheek that doesn't heal in two weeks. According to the National Cancer Institute, any lesion persisting this long warrants evaluation. Make a note: "two-week rule" to self-assess and prompt timely dental visits.

  2. Color changes: leukoplakia vs. erythroplakia -

    White patches (leukoplakia) or red patches (erythroplakia) in the mouth can be precancerous, as highlighted by the Oral Cancer Foundation. Tracking these with a simple spot-check helps you stay alert. Remember the phrase "White to watch, red to dread" to recall which patches need urgent review.

  3. Memorize key warning signs with the S-L-A-P mnemonic -

    Use S-L-A-P to remember Sore (persistent), Lump (mass or bump), Abnormal patches, Pain (unexplained). This easy trick is backed by dental associations to ensure you don't overlook early symptoms. Repeating "S-L-A-P yourself monthly" can make self-tests a breeze.

  4. Understand and assess major risk factors -

    Tobacco use, heavy alcohol consumption, and HPV infection are proven risks - in fact, combining smoking and drinking can increase oral cancer risk up to 38-fold (Journal of Oral Oncology). Age over 50 adds another layer of risk. Factor these into your quiz results to see where you stand compared to population norms.

  5. Perform a systematic self-exam routine -

    Grab a flashlight and mirror, then inspect inner cheeks, gums, tongue, and throat in an "L-shape" pattern to ensure no area is missed. The Oral Health Foundation recommends doing this once a month, marking any concerns on a simple diagram to track changes. A stepwise flowchart ("Mirror first, lift tongue, feel cheeks") keeps your check both quick and thorough.
