Cancer inside of the tongue.

Over 70% of patients with oral cancer treated at the Clinical Hospital of the University of Campinas (Unicamp), in São Paulo, arriving with advanced disease. The unit receives about 10 new cases every month and serves an average of 30 patients under treatment at the clinic.

The National Cancer Institute (NCI) estimates that last year, nearly 10,000 new cases of the disease have been identified throughout the country.

This type of cancer affects generally men over 50 years, smoking and drinking abusively, explains José Alfio Tincani, head and neck surgeon, Department of Surgery, HC. It indicates other risk factors, and the consumption of alcoholic beverages and tobacco in excessive quantities, such as poor oral hygiene, prolonged sun exposure and oral sex without protection that may also trigger this type of tumor. But the doctor explained that the risk factors are linked to different types of the disease.

The disease is characterized by the presence of a malignant tumor in the oral region and manifested primarily by the presence of wounds on the edge of the tongue, which can often be confused with canker sores, being diagnosed late.

"This type of cancer affects generally men over 50 years, smoking and drinking abusively"

Oral cancer or oral cancer manifests itself in the lip, mouth part, is more common in people who are exposed to sunlight for too long without protection, as is the case of rural workers. Have cancer that manifests itself on the inside of the mouth, tongue mobile call is linked to the risk group of men over the age of 50 alcoholics and smokers. Finally, he says, cancer-related risk of unprotected sex is actually oropharyngeal cancers, in the region between the mouth and pharynx.

<b> HPV </ b>

In the latter, research related to the presence of human papillomavirus virus (HPV) incidence of oropharyngeal cancers, also resulting in the emergence of the disease in women and youth, two groups that heretofore were not considered at risk. Today, more than 90% of the cases of this cancer in young people without other causes of risk may have the presence of HPV in biopsies explains Tincani.

The discussion still controversial and presents a risk, ie, has not proven much is the use of ill-fitting dentures for long periods. With incorrect usage, there may be trauma in the mucosa of the mouth and the onset of cancer or gum called floor of the mouth, says the teacher. He warns of the risk of late diagnosis, very common in patients treated at HC. Many people find it simple and treat a wound on their own account and adds that if the injury or wound persists for more than four weeks, the person should see a doctor. For the diagnosis is necessary to do a biopsy on the spot.

Treatment <b> </ b>

From the identification of the disease and its stage, the patient can do the treatment by surgery, radiotherapy or chemotherapy. According Tincani, the method used depends on the size of the lesion and also the choice of the patient to discuss with your doctor the options available. In the initial tumors, can be made surgery to remove the tumor or treatment with radiotherapy and in advanced cases, surgery more radicals, with the withdrawal of lumps - nodes - in conjunction with the tumor and subsequent treatment with radiotherapy. After the procedure, the patient is monitored every three months with the doctor and in some cases there may be sequels in speech and swallowing.

In patients with the disease and have HPV, usually the treatment presents a better outcome with the use of combined chemotherapy and radiotherapy. In Clinical Hospital of Unicamp are performed about 70 surgeries to remove tumors in the mouth every year and the division of radiotherapy hospital on average 14 patients / month perform the treatment, consisting mostly of 35 sessions. With preventive care and observation of possible mouth sores, the disease can be identified early, facilitating treatment and increasing the chances of a cure.
