Lip & Oral Cancer Overview
Lip and oral cavity cancer is a type of head and neck cancer. Men in the United States are diagnosed with this type of cancer about 2.3 times more often than women. Lip and oral cancer can form in several different areas including the tissues of the lips, oral cavity (the mouth) or the oropharynx (the part of the throat at the back of the mouth).
The oral cavity includes the following:
- Hard palate (the roof of the mouth)
- Soft palate and (the muscle back portion of the roof of the mouth)
- Retromolar trigone (the small area behind the wisdom teeth)
- Front two-thirds of the tongue
- Gingiva (gums)
- Uvula (the fleshy extension off of the soft palate that hangs above the throat)
- Buccal mucosa (the lining of the inside of the cheeks and lips)
- Floor (bottom) of the mouth under the tongue
- Salivary glands (glands that make saliva)
Risk Factors for Lip & Oral Cancers
Tobacco and alcohol use are the two main factors that seem to affect the risk of developing lip and oral cavity cancer. Most patients diagnosed with this disease are over 60 years old. Always consult your doctor if you think you may be at risk for cancer.
Risk factors for lip and oral cavity cancer include the following:
- Using tobacco products of any type
- Heavy alcohol use
- For women: having more than three drinks on any day or more than seven drinks per week
- For men: have more than four drinks on any day or more than 14 drink per week
- Overexposure to natural sunlight or artificial sunlight (such as from tanning beds) without UV protection
- Being male
- Being infected with human papillomavirus (HPV)
If you have risk factors it does not mean that you will definitely develop cancer. And at the same time, having no risk factors present is not a guarantee that you won't develop a type of lip or oral cancer. That’s why it’s important to know how to spot signs and symptoms.
