Study Notes
Oral Cancer: Epidemiology, Risk Factors, and Prevention
- Oral cancer is a group of diseases characterized by uncontrolled growth of abnormal cells.
- Worldwide, the leading causes of death in 2019 were diseases of the heart and blood vessels, followed by cancers such as lung, and prostate cancer.
- In males, lung cancer is the leading cause of cancer death, followed by liver cancer and prostate cancer.
- In females, breast cancer is the most frequently diagnosed cancer and is also the leading cause of cancer death.
- Globally, cancer is a significant health issue, and the incidence and mortality rates vary by region.
- Cancer risk factors, including tobacco use, alcohol consumption, and HPV infection, are important to consider.
- Modifications like lifestyle changes and quitting smoking can reduce oral cancer risk.
Global Epidemiology
- Cancer is a global health concern.
- Data on incidence and mortality are gathered from various countries.
- Data quality and representativeness varies across regions.
- Global cancer statistics are compiled for 36 cancers in 185 countries for 2020.
- The estimates do not reflect the full impact of the COVID-19 pandemic.
Oral Cancer Risk
- Oral cancer is a multifactorial disease.
- Non-modifiable risk factors include age and ethnicity.
- Modifiable risk factors include tobacco use, alcohol consumption, and betel quid chewing.
- Emerging risk factors include HPV infection, immunosuppression, and poor oral hygiene.
Oral Cancer Incidence Data
- Data sources for oral cancer are varied, including cancer registries in areas like Cebu, Manila, and Rizal.
- Key oral cancer sites include the mucosal lip, buccal mucosa, alveolar ridge, retromolar trigone, floor of the mouth, hard palate, and anterior two-thirds of the tongue.
- Oral cancer incidence data can be used to track trends and understand risk factors.
Oral Cancer Prevention
- Stopping tobacco use is a critical preventive step.
- Education and awareness campaigns can help prevent oral cancer.
- Early detection is crucial for better prognosis and improved survival.
Oral Cancer Screening
- Examine your mouth, neck, lips, and gums for any changes.
- Look for lumps, bumps, sores, redness, or white patches.
- Use a mirror to examine hard-to-reach areas.
- If you notice suspicious changes, contact a dentist for a proper evaluation.
Premalignant Lesions
- Leukoplakia is characterized by white patches in the oral cavity that are caused by chronic irritation and cannot be rubbed off easily.
- Lichen planus is another premalignant lesion that's an inflammatory autoimmune reaction in the oral cavity.
- High-risk areas for oral cancer include the floor of the mouth, lateral border of the tongue, and soft palate.
Cancer Staging and Treatment
- Staging determines the extent of cancer and guides treatment decisions.
- Treatment approaches include surgical removal of the tumor, radiation therapy, and/or chemotherapy.
- Complete removal of the lesion, minimizing the damage to surrounding tissues, is a key strategy.
HPV-Related Oral Cancers
- Human Papillomavirus (HPV) infection is associated with an increased risk of oropharyngeal cancers.
- HPV subtypes 16 and 18 are associated with a significant portion of oropharyngeal cancers.
