Canker ulcer of what appearance can produce change cancer?
How to prevent the potential cancer risk of oral ulcer?
Once they find out they have a mouth ulcer, many people’s first reaction is “Can it become cancer?
The oral mucosa clinic of our hospital often sees such worried patients.
In fact, the vast majority of people’s mouth ulcers will not become cancer, but it is true that some mouth ulcers will become cancer.
So what kind of mouth ulcer will become cancer?
To answer this question accurately, still have to speak from what call oral mucous ulcer.
Distinguishing “ulcers” from “erosions” ulcers first need to be distinguished from another lesion, “erosions”, which are also common in the oral mucosa.
The academic definition of “oral mucosal ulcer” is “persistent defect or destruction of the integrity of the mucosal epithelium, resulting in depression due to necrosis and shedding of the surface layer”.
“Erosion” refers to “a partial superficial defect of the oral mucosal epithelium with irregular size and shape and blurred boundaries”.
It may be too technical to say, for example, that an ulcer is like a hole in the lining of a new dress. The “hole” is more regular around, not “sizzling”;
But “erosion” is like worn for decades on the old clothes “rub out” marks, not completely broken, but the cloth body has become thin, there is a “hole is not a hole” feeling.
The reason why we should distinguish between “ulcer” and “erosion” is that “erosion” of oral mucosa is not only seen in infectious diseases such as herpes, but also in precancerous lesions such as lichen planus, discoid lupus erythematosus, leukoplax, etc., which requires more attention and vigilance than “ulcer”.
Distinguishing between benign and malignant ulcers Now, back to ulcer.
In fact, oral mucosal ulcer strictly speaking is not a disease, but a symptom, many oral mucosal diseases can occur.
For example, recurrent aphthous ulcer, traumatic ulcer, oral tumor, various oral mucosal infectious diseases, the later stage of bullous disease, some venereal diseases, and the oral manifestations of chronic diseases such as blood diseases, diabetes, autoimmune diseases, etc.
Therefore, for “ulcer”, according to its pathological characteristics and prognosis, distinguish between benign and malignant two categories.
The classic example of a “benign ulcer” is a “recurrent aphthous ulcer”.
This is a mouth ulcer that can happen to almost anyone.
Its clinical symptoms can be summarized as “red, yellow, concave, pain”, that is, when the ulcer attack, edge congestion, yellow and white pseudomembrane on the surface, central depression, accompanied by obvious pain, affecting language and eating.
It can be accompanied by a low-grade fever, which usually resolves itself in two weeks.
This kind of ulcer attack location “hit a gun for a place”, can have a different length of “truce period”, but there are also patients “war fire even for three months”, oral ulcer in succession, one after another.
The good news is that this painful ulcer does not turn cancerous, so it is not worth worrying about.
Corresponding to this is “malignant ulcer”, the most typical is “oral squamous cell carcinoma”.
Unlike the aforementioned “recurrent aphthous ulcer”, this ulcer itself is cancer, called “cancer ulcer”.
This ulcer has a long time, large area, hard base, edge turned out to be cauliflower, pain is not obvious, but “wood” characteristics, some people put it down to “long, big, hard, turn, wood” five words.
If a patient’s ulcer meets these five words, it is not a question of whether it will change or not. It is a question of taking active measures, such as early surgery or other comprehensive treatment.
