Can esophageal cancer cause laryngeal cancer?

Esophageal cancer generally does not cause pharyngeal cancer. Most patients with chronic pharyngitis have reasons, such as chronic sinusitis, gastroesophageal reflux disease, frequent use of the throat, or patients with smoking habits, as well as frequent exposure to harmful gases. These are the causes of chronic pharyngitis, and these causes need to be fundamentally eliminated before chronic pharyngitis can gradually improve.

Causes of Throat Cancer

(1) Smoking: The burning of tobacco can produce tobacco tar, among which benzopyrene can cause cancer. Tobacco smoke can also stop or slow the movement of cilia, cause mucosal edema and bleeding, and cause epithelial hyperplasia, thickening, and squamous metaplasia, which becomes the basis for cancer.

(2) Excessive drinking: Long-term stimulation of the mucous membrane can cause it to degenerate and cause cancer.

(3) Chronic inflammatory irritation such as chronic laryngitis or respiratory tract inflammation.

(4) Air pollution: Long-term inhalation of harmful gases such as sulfur dioxide and industrial dust such as chromium and arsenic can easily cause laryngeal cancer.

(5) Viral infection is closely related to the occurrence of cancer. It is generally believed that viruses can change the nature of cells and cause abnormal division; viruses can attach to genes and be passed on to the next generation of cells, causing cancer.

(6) Precancerous lesions: Repeated attacks of laryngeal keratosis and benign laryngeal tumors such as laryngeal papilloma may lead to cancer.

(7) Radiation: Radiation treatment of neck tumors may cause cancer.

(8) Sex hormones: Relevant experiments have shown that the percentage of estrogen receptor-positive cells in laryngeal cancer patients is significantly increased.

From the causes of laryngeal cancer, it can be concluded that esophageal cancer generally does not cause laryngeal cancer.
