A 6 1 year-old patient surnamed Lin in Central China received long-term renal dialysis treatment. Recently, I suddenly went to the hospital for vomiting blood. After examination, he found a lump on his tongue, the size of which was like a marinated egg. After biopsy, it was diagnosed as "oral cancer". Doctors say that the immunity of renal dialysis patients is generally low. Once there are ulcer lesions in the mouth, there are bad habits such as smoking and chewing betel nut, which is easy to accelerate and deteriorate into oral cancer.

Dr. Cai Shaoqing reminded that if renal dialysis patients have the habit of smoking, drinking and chewing betel nut, they may increase their chances of developing oral cancer. (Photo courtesy/Children's General Hospital) Cai, director of the Department of Otolaryngology, Children's General Hospital, said that the occurrence of oral cancer is related to long-term oral contact with * * *, which leads to cell degeneration. The possible causes of oral cancer include smoking, drinking, betel nut chewing, syphilis, excessive sunlight, long-term nutritional deficiency, poor oral hygiene, long-term consumption of overheated or * * * food, sharp tooth decay, plaque rupture, improper manufacture of dentures and braces, etc.

Dr. Cai Shaoqing further pointed out that due to the decreased immunity of renal dialysis patients, if they do not pay attention to oral hygiene, they may be infected by viruses and bacteria, causing oral ulcer lesions and even cancer; Especially patients who have the habit of smoking and chewing betel nut are more likely to suffer from oral cancer than ordinary people.

In terms of treatment, renal dialysis patients usually can't accept traditional treatment methods such as extensive tumor resection, lymph node dissection, free flap reconstruction or chemotherapy, and can only be given targeted drug therapy plus liver metabolism chemotherapy after local tumor resection. Take the patient surnamed Lin as an example. After 1 month of treatment, the condition has stabilized and there is no vomiting blood.

Statistics show that Taiwan Province Province has the highest renal dialysis rate in the world in recent five years, and oral cancer among young and middle-aged men ranks first among the top ten causes of death. Dr. Cai Shaoqing reminded people not to smoke, drink and chew betel nut, especially patients with renal dialysis should pay more attention to their health. If you find that the oral ulcer has not healed for more than 2 weeks, you must seek medical treatment as soon as possible, find out the reason and receive treatment.
