Lip cancer-malignant neoplasm, originating from the cells of the integumentary epithelium of the red border of the lips.

Lip cancer accounts for about 3% of all malignant tumors (8-9th place). The cancer of the upper lip is much less than that of the lower lip - it occurs in 2-5% of cancers of the lip, but at the same time it is more aggressive, according to the Internet publication for girls and women from 14 to 35 years old Pannochka. net Men suffer this type of cancer more often than women (more than 76% of cases). The peak incidence falls on the age of over 70 years. Lip cancer is most commonly found in rural areas.

Causes of Lip Cancer The causes of cancer of the lip include:.

exposure to sunlight frequent exposure to high temperatures frequent mechanical injuries smoking (especially tubes), chewing tobacco chemical carcinogens: arsenic, mercury, bismuth, anthracite, liquid tar, oil distillation products alcohol viral infections chronic inflammatory processes Symptoms of Lip Cancer Lip cancer always occurs on background of another lip disease and never - from a healthy tissue. Sometimes the cancer arises from leukoplakia or a crack, sometimes - from a papilloma or a warty form of dyskeratosis.

First, a small seal appears over the surface of the lip. In the center of the neoplasm, erosion or an ulcer with a granular surface and a cylindrical margin occurs. Education has fuzzy boundaries and is gradually increasing in size. The tumor is covered with a film, the removal of which is painful. Under the film, bumpy growths.

The tumor gradually grows, destroying surrounding tissues and significantly infiltrating. Secondary infection joins the neoplasm. The infiltrate extends to the cheek, chin, and lower jaw. Regional lymph nodes initially dense, painless and mobile. With the growth of metastases, lymph nodes increase in size, neighboring tissues germinate and lose mobility. In advanced stages, metastases are transformed into large decaying infiltrates.

Gradually, food is disrupted, tissue disintegration joins, cachexia develops.
