Esophageal cancer causes play the most basic role in development of tumors in esophagus. Causes also play a decisive role in pace of metastasis of tumors and directly affect esophageal cancer survival rate of the victim. Understanding causes helps to identify esophageal cancer symptoms in a better manner and increases overall effectiveness of esophageal treatments undergone.
Understanding Esophageal Cancer Causes
Esophageal cancer is a malignant growth of cancerous tumors in esophagus. Esophagus is the main linkage between stomach and mouth and passage of swallowed food from mouth to stomach takes place through esophagus. Thus, development of polyps (benign or cancerous) in esophageal areas directly obstructs passage of food and cause pains during intake of food-stuffs. This puts severe restrictions on eating pattern of the victim and leads to unexpected loss of weight and loss of appetite. Situation becomes severe in advanced stages of the disorder and a person may have to survive only on liquid diet.
Survival rate for esophageal canceris extremely low and is not more than 50% in the initial stages. Chances of survival depend on various factors like age of victim, esophageal cancer stage a person is suffering from, pattern and diagnosis done to identify nature of tumor-growth, presence of other cancerous or non-cancerous disorders in the victim, and status of immune system of the patient. According to American Cancer Society (United States of America), chances of survival of a victim in the initial stages are not more than 37% when the tumors are restricted only to local areas. Chances of fair life expectancy decrease further when the tumors spread to adjacent and regional tissues and are not more than 18%. Survival rate is extremely less in final stages and may not cross even 5%. Though early detection is a key to high rate of survival, esophageal cancer prevention is the safest option to avoid irreparable health complications.
Prevention of esophageal cancer can be better carried by understanding basic esophageal cancer causes. Smoking is a very common cause of cancerous growth in esophageal areas and causes severe damage to tissues and cells in the region. Such damage instigates abnormality among cells and further leads to malignancy. One should also avoid chewing tobacco as it contains high amounts of carcinogens. Alcohol consumption is also bad for body cells and tissues and may lead to primary or secondary form of esophageal cancer. Primary esophageal cancer is the one originating in the esophagus while secondary form of this disorder is caused due to metastasis of cancer cells to esophageal areas. Such cells usually develop in other adjacent or remote organs and reach esophagus mainly through lymph nodes.
Esophageal cancer is less prevalent in females and occurs mostly in people older than 50 years. Non-cancerous disorders of esophagus like Gastroesophageal Reflux Disease (GERD), frequent ulcers or injuries in the esophagus that remain untreated, and infection by HPV (Human Papillomavirus) are some other important causes of esophageal cancer. Some food-stuffs or beverages include high content of alkali or acids and may lead to early cancerous development in the region. Thus, one should consume hygienic and nutrient-rich food and avoid drinking beverages that cause throat irritation or irritation in esophageal areas. Thermal injuries (occurring mainly due to intake of very hot beverages or food-stuffs) can also cause esophageal cells to behave abnormally.
Esophageal cancer causes can put different form of impact on different people. Strong immune system is very helpful to decrease the intensity of causes on victim’s health. It also helps to restrict tumors to a particular area in the initial stages and ease process of their detection and cure.
