Leukoplakia is a solidly attached white fix on a mucous film and is associated with an increased risk of malignant growth. The edges of the injury are usually abrupt, and the sore changes over time. Red patches may form as a result of advanced structures. For the most part, there are no different indications. It typically occurs inside the mouth, though mucosa [1] in other parts of the gastrointestinal tract, urinary tract, or privates may be affected. The cause of leukoplakia is unknown. Smoking, chewing tobacco, excessive alcohol, and the use of betel nuts are all risk factors for development inside the mouth. In HIV/AIDS, one explicit type is usual. It is a precancerous sore tissue modification caused by malignant growth. The malignant growth depends on the type, with 3–15 percent of confined leukoplakia [2] forming into squamous cell carcinoma and 70%–100% of proliferative leukoplakia forming into squamous cell carcinoma. Leukoplakia is a specific term that should be used only after all other possible causes have been diagnosed. Generally shows increased keratin build up with or without abnormal cells, but is not diagnostic. Treatment is based on the components of the injury. If abnormal cells are present or the injury is minor, careful evacuation is frequently recommended; however, close development at three to six-month intervals may be sufficient. Individuals are generally encouraged to quit smoking and limit their alcohol consumption. Leukoplakia will shrivel in up to 50% of cases if smoking is stopped; however, if smoking is preceded, up to 66% of cases will turn out to be whiter and thicker. The percentage of people influenced is estimated to be 1%–3%. Leukoplakia [3] becomes more common with age, usually not occurring until after the age of 30. Rates in men over the age of 70 could be as high as 8%. The precise cause of leukoplakia is unknown, but it may be multifactorial, with tobacco use being the most important factor. Tobacco use and other suggested causes are discussed further below. Hyperkeratosis is the thickening of the keratin layer that causes the white appearance. When the strange keratin is hydrated by spit, it appears white, and light reflects equitably off the surface. This conceals the normal pink-red colour of mucosa (the consequence of hidden vasculature appearing through the epithelium). A comparable situation can be observed on toughness areas such as the bottoms of the feet or the fingers after prolonged submersion in water. Acanthosis, or thickening of the layer spinosum (a layer of the epidermis found between the stratum granulosum and stratum basale), is another possible component. A frictional or irritating injury that causes keratosis is another extremely common cause of white patches in the mouth. Models include nicotine stomatitis, which is keratosis caused by tobacco smoking's warmth (as opposed to a reaction to the cancer-causing agents in tobacco smoke). Mechanical injury, such as a sharp edge on a dental replacement or a chipped tooth, can result in white patches that look similar to leukoplakia [4].

Nonetheless, these white patches are a typical hyperkeratosis response (skin's response to rubbing or irritation), similar to a callus on the skin, and it will go away once the cause is removed. When there is a verifiable cause, such as mechanical or thermal injury, the term idiopathic leukoplakia should not be used.
