Why is the prognosis of laryngeal cancer closely related to the location of the tumor? Do you know the secret behind this?
Laryngeal cancer, or throat cancer, is a cancer that can occur anywhere in the throat. Most of these tumors are composed of squamous cell carcinomas, reflecting their origin from the laryngeal epithelium. Research shows that tumor location has a huge impact on prognosis, so it is important to understand the reasons behind this.
Correlation between tumor location and prognosis
When describing laryngeal cancer, the medical community usually divides the larynx into three anatomical regions: the glottis (i.e., the true vocal cords), the epiglottis (the epiglottis, annulus, and surrounding tissues), and the infraglottis. Many laryngeal cancers originate in the glottis, while cancers of the epiglottis and subglottis are less common. Studies have found that the specific areas where these tumors are located will directly affect the choice of treatment and subsequent prognosis.
Where the tumor is located in the larynx is very critical and will affect how it spreads and the patient's survival rate.
Symptoms and risk factors
The symptoms of throat cancer vary depending on the size and location of the tumor. Common symptoms include voice changes, sore throat, difficulty swallowing, etc. Most people with throat cancer experience persistent throat discomfort, which may be accompanied by earache or cough.
In terms of risk factors, the most important risk factor is undoubtedly smoking. Throat cancer mortality among heavy smokers is twenty times higher than among non-smokers. In addition, the combination of alcohol abuse and smoking will greatly increase the chance of developing throat cancer.
Diagnosis and staging
The diagnosis of laryngeal cancer is usually based on medical records, physical examination and imaging tests. Doctors will use chest X-rays, CT or MRI scans, and perform tissue biopsies to confirm the presence of the condition. When performing a biopsy, the surgeon may even attempt to completely remove the tumor during the first examination.
A system of tumor staging can help predict treatment options and influence subsequent medical decisions.
Treatment strategies
The treatment of laryngeal cancer often depends on the type, location and stage of the tumor, and can be divided into various methods such as surgery, radiotherapy and chemotherapy. Surgery may require partial or complete removal of the tumor, depending on its involvement with surrounding tissue. In some cases, complete resection of the larynx is necessary.
During treatment, the patient's overall health and wishes will be important considerations.
Epidemiology
According to statistics, approximately 12,500 people in the United States suffer from throat cancer every year. Recent statistics show that the number of new cases each year has dropped, which is related to the impact of public health policies to reduce smoking, and throat cancer is also classified as a "rare disease".
Conclusion
The correlation between the prognosis of laryngeal cancer and tumor location demonstrates the importance of medical diagnosis and treatment. Understanding these factors not only helps medical staff make the best medical decisions, but also allows patients to achieve better treatment outcomes. What new discoveries or treatments do you think should be focused on in future research on laryngeal cancer?
