Overview
Common causes of oral cancer include premalignant lesion, tobacco, alcohol, human papillomavirus, and hematopoietic stem cell transplantation.
Causes
Common causes of oral cancer include:
- Premalignant lesion[1]
- Benign and morphologically altered tissue
- Premalignant lesions are of various types:
- Leukoplakia - benign white patches
- Erythroplakia - red patches
- Erythroleukoplakia - mixed red and white patches
- lichen planus
- Oral submucous fibrosis - very common in Indian subcontinent
- actinic cheilitis
- Tobacco
- 75% cases of oral cancers occur due to tobacco.
- It causes irritation of mucous membrane in the mouth.
- Both smoking and chewing tobacco can lead to irritation of mucous membrane of the mouth.
- 60 types of carcinogens are known to occur in tobacco smoke.
- If any form of tobacco use is combined with heavy alcohol intake, the carcinogenic potential increases.
- Alcohol
- Human Papilloma Virus(HPV)
- HPV type 16 is the most common subtype associated with oral cancer.
- Unprotected oral sexual behaviours with a patient suffering from HPV can transmit this virus.[2]
- Most commonly involves tonsils, base of the tongue and the oropharynx.
- Hematopoietic Stem Cell Transplantation
- Higher risk for squamous cell carcinoma
