Cheek Mucosa Cancer
Cheek mucosa cancer is the second most common (after tongue cancer) in the structure of oral cancer. Local factors, chemical and physical agents that cause chronic mucous membrane injury have a significant impact on increasing risk. To a greater extent than in the case of cancer of other areas, a predisposing factor such as chronic traumatization of dentures, sharp edges of damaged teeth is relevant.
Cancer of the bottom of the mouth cavity
This type of tumor is 10-15% of all oral cancers. The bottom of the oral cavity is formed by structures between the tongue and hyoid bone. The mucous, lining the bottom of the mouth cavity has a developed submucosal base consisting of loose connective tissue and fiber. This area is richly supplied with blood. All this creates favorable conditions for tumor growth, its proliferation and metastasis.
Tongue cancer is the most common type of oral cancer. Tongue – a mobile organ with a large number of nerve endings (receptors). Due to this, patients, as a rule, pay attention to the emerging neoplasm, and have the opportunity to seek help in time. Developed network of blood and lymphatic vessels contributes to early tumor metastasis, primarily – in the peripheral lymph nodes.
Cancer in the alveolar process area
Cancer in this area develops either from mucous membrane cells or from epithelial islets of Malasse. Epithelial islets Malasse are the remnants of epithelial cells in the thick of the periodontal column. Normally, these cells do not manifest themselves in any way, but under unfavorable conditions can become a source of tumor. Distinctive feature of these tumors – relative to the early onset of symptoms, teeth in the tumor growth zone are exposed to it, the patient has complaints of pain.
Cancer of the sky
Sky cancer is rare. Separate hard and soft sky, so the histological types of tumors of soft and hard sky are different. Cylindromes and adenocarcinomas are more characteristic of the hard sky, the soft sky is more susceptible to flat cell cancer.
The metastatic nature of oral tumors is very rare. Cases of tumors of the lungs, kidneys, mammary and thyroid glands that metastasized into the oral cavity have been described. Sarcomas can also be metastasized into the oral cavity. More often the signs of oncopathology in the oral cavity may be caused by the growth of a tumor from neighboring anatomical areas. Clarification of the diagnosis is helped by a histological examination of the tumor tissue.
