According to a report by Amar Ujala, the problem of mouth ulcers is very common, and anyone from children to elders can fall victim to it. People often face this trouble due to accidentally biting the cheek or tongue, using a brush with hard bristles, or in some cases due to a deficiency of vitamin B-12 and folate. Generally, these ulcers heal on their own or with mild treatment, but if you face this problem repeatedly in your mouth or if the ulcers take a very long time to heal, one should not make the mistake of ignoring them. Sometimes, an ulcer remaining in the mouth for a long time can also prove to be an early sign of cancer.
The worrying matter is that cases of oral cancer are increasing very rapidly among the youth class as well. This serious disease can affect the tongue, gums, lips, and the inner part of the cheeks. According to health experts, if an ulcer in the mouth does not heal for 3 weeks or if any unusual lump, swelling, or white-red mark is seen, getting it examined immediately is imperative. Keeping the rising cases of oral cancer in mind, health experts have appealed to all citizens that they should regularly examine their mouths and try to identify the early signs of cancer.
Especially in the last 20 years, an increase of more than double has been recorded in the cases of oral cancer. Surprisingly, its symptoms are coming to light even in people under 50 years of age. It is revealed from a study of the Oral Health Foundation that despite the increase in the cases of this disease, awareness regarding its early symptoms has not increased adequately among people yet. Catherine Brady, the chair of the Oral Health Foundation and a registered dentist, says that upon getting an ulcer, some type of mark, or a lump in the mouth, people often consider it a normal problem and ignore it. Especially when there is no pain in it, people's attention does not go towards it. But if any kind of change in the mouth persists for more than three weeks, getting it examined by a doctor is extremely necessary.
Health experts believe that mouth cancer can happen to any person. Just like other serious diseases, in the case of oral cancer too, timely identification plays a very important role. The earlier the disease is caught, the better the probability of its treatment succeeding remains. In a report published in Britain's local media, a woman named Karen Lishing-Schroder shared her experiences and stated that she had initially ignored her symptoms and later found out that she was suffering from tongue cancer. In the initial stage, a small ulcer had occurred on her tongue.
The Oral Health Foundation is a leading organization that works to spread awareness among people regarding oral health and oral cancer. Studies are conducted from time to time by this organization so that awareness can be brought at a global level regarding the increasing risk of oral cancer and its early symptoms.
