According to scientific statistics, nowadays, the number of people suffering from pharyngitis is very large, and even about 60% people in the world have pharyngitis problems.
Therefore, we must pay more attention to the prevention and treatment of pharyngitis in our life, so as to avoid the harm of the disease to the body.
Understand pharyngitis:
Pharyngitis is a non-specific inflammation of the pharynx, which is a general term for inflammation caused by various microorganisms infecting the pharynx. It can exist alone, coexist with rhinitis, tonsillitis and pharyngolaryngitis, or be a precursor of some diseases.
It can be divided into acute pharyngitis and chronic pharyngitis.
Acute pharyngitis is an acute inflammation of pharyngeal mucosa and submucosal tissue, and the pharyngeal lymphatic tissue is often involved, and the inflammation can be localized in the early stage, and the whole pharyngeal cavity can often be involved with the progress of the disease.
The main manifestations are dryness, burning, pain, obvious swallowing pain, congestion and swelling of the pharynx.
Chronic pharyngitis is characterized by chronic congestion of pharyngeal mucosa, hyperplasia of mucosa and submucosal connective tissue, hypertrophy of mucous glands, hypersecretion and increased mucus secretion.
Patients often cough up phlegm in the pharynx, or feel foreign body sensation in the pharynx, which can't be coughed up and swallowed. What's more, it will be accompanied by follicular hyperplasia and painful, which is common in adults, with long course of disease, easy recurrence and stubborn symptoms.
In life, many people can't tell the difference between esophageal cancer and chronic pharyngitis. In fact, the parts where they occur are very similar, so it will easily lead to confusion and delay the illness.
But judging from a professional point of view, there is still a big gap between them. Let's listen to the doctor's analysis!
What is esophageal cancer?
Esophageal cancer is a common malignant tumor of digestive tract, mainly from below the mouth to the gastric junction. Generally, the incidence is relatively high among Asian people; The age of onset is mainly 50-70 years old, and the age of high incidence is 60-65 years old.
The common symptom of esophageal cancer is progressive dysphagia. At first, it may be difficult to swallow solid substances. As time goes on, liquid diet will also cause dysphagia; In the later stage, milk and water can't be eaten normally.
Thought it was chronic pharyngitis, but found esophageal cancer, how to distinguish the two?
Chronic pharyngitis is mainly stimulated by repeated acute inflammation, which leads to the proliferation of lymph tissue in the throat. You can touch the lump-shaped protuberance with your hands, accompanied by symptoms such as sore throat, itchy throat and foreign body sensation.
Esophageal cancer mainly occurs in the esophagus, mainly in the middle section, and the symptom is pain when swallowing. If the tumor grows gradually, it will be difficult to eat when the esophagus is pressed, and it will be accompanied by enlarged lymph nodes in the neck and armpits.
Tumors may break through the esophagus and involve the throat, and you can see cauliflower or ulcer-like new organisms. Patients with advanced tumors will also have metastases in the liver and lungs.
Four differences to keep in mind
First, esophageal cancer mostly occurs in middle-aged and elderly people.
Secondly, esophageal cancer has no obvious inducement.
Thirdly, the degree of dysphagia in esophageal cancer is more serious.
Fourthly, esophageal cancer is accompanied by various symptoms.
Reading extension: The causes of esophageal cancer usually include the following:
First:
Unhealthy eating habits, patients with esophageal cancer often have the habit of eating hard, rough and overheated food, which will cause damage to the epithelial tissue of esophageal mucosa, lead to the formation of local ulcers, and eventually develop into esophageal tumors.
At the same time, patients who smoke for a long time will cause persistent vasoconstriction of esophageal mucosa, leading to ischemic changes and inducing the formation of esophageal cancer.
Second:
Long-term lack of trace elements such as vitamin A and vitamin B2 in patients' diet will slow the repair of damaged esophageal mucosa and increase the risk of esophageal cancer.
Third:
Patients with chronic esophagitis and corrosive injury of esophagus. With the aggravation of the disease, it will slowly develop into esophageal cancer.
