Oral Cancers
Premalignant
Leukoplakia
most common in adults, most often see in men
Slow developing changes in the oral mucousa
Thick, white, firmly attached, slightly raised and sharply circumscribed patches (can not be removed by scraping)
Small percentage become malignant after about 8 years
Lesions on lips and tongue most likely to become malignant

Causes
Long term irritation to the oral membranes

Squamous Cell Carcinoma
Most common of the oral cancers
Usually found on lips, tongue, buccal mucosa, oropharynx
Occurs because over many years cell changes take place in the oral cavity
