Globally, lung cancer ranks as the second most common cancer, and it claims a significant number of lives each year. However, it remains a misunderstood disease due to several myths surrounding it.
Lung cancer originates in the lung tissues, particularly in the cells lining the air passages. Uncontrolled growth of these cells leads to damage to lung tissue and can hinder lung function. Lung cancer symptoms typically appear at advanced stages, with only 15% of cases diagnosed early. Therefore, it is crucial to be aware of the facts about lung cancer to promote early detection and improve treatment outcomes, particularly for those at high risk.
Fact: While it's true that smoking is a significant risk factor for lung cancer, it’s important to recognize lung cancer can also occur in non-smokers.
Various factors contribute to lung cancer in non-smokers, such as family history, exposure to radon gas, second-hand smoke, air pollution, workplace carcinogens like asbestos, chest radiation therapy in the past, chronic lung diseases, and other environmental toxins.
Fact: While lung cancer predominantly affects men, it is essential to note that a notable proportion of women diagnosed with lung cancer are non-smokers. The influence of genetic and hormonal disparities between genders in lung cancer development is an ongoing area of research.
Fact: Quitting smoking at any point can significantly reduce the risk of developing lung cancer and other related diseases. In fact, 10 years after quitting smoking, the risk of lung cancer decreases by approximately 50% compared to persistent smokers. Moreover, quitting smoking, before or after a lung cancer diagnosis, can enhance the effectiveness of treatment and significantly improve the chances of survival. Quitting smoking, after the diagnosis of any type of cancer, improves in the quality of life and prolongs survival.
Fact: The average age of lung cancer diagnosis is approximately 70, however, it's important to recognize that younger individuals, including non-smokers, can develop the disease. Certain types of lung cancer, such as adenocarcinoma, are more prevalent in non-smokers and younger age groups.
Fact: CT scans for lung cancer only emit low dose radiations, about a quarter of a regular CT scan. The benefits of catching lung cancer early through screenings are much greater than the slightest risk from radiation exposure, especially for those at high risk.
Fact: Early diagnosis can greatly increase the chances of successful treatment and long-term survival. Some types of lung cancer have specific genetic signatures that doctors can target with special treatments, leading to better results and higher chances of survival. Hence, it's essential to be aware of the signs and symptoms and to seek medical attention promptly upon experience symptoms or have a history of smoking or other risk factors.
Fact: Lung cancer may be asymptomatic particularly in the early stages. Hence, its regular lung cancer screenings are essential, particularly for high-risk individuals. Early detection can lead to better outcomes and increased chances of survival. If you are at high risk, talk to your doctor about screening options.
Understanding the facts about lung cancer is essential in dispelling common myths surrounding the condition. It's vital to raise awareness, promote early detection, and encourage lifestyle changes to reduce the risk of lung cancer.
