Our elders often say that the very name "cancer" feels ominous, and no form of cancer is considered less serious than the others. However, there is one type of cancer that is considered the most dangerous because it causes the highest number of deaths. Yet, people continue to use products that contribute to this cancer without fear.
You might think the deadliest cancers are brain or blood cancers, but based on certain facts, lung cancer is considered the most dangerous. And these facts are nothing other than the number of deaths caused by different types of cancer. Yes, worldwide, lung cancer accounts for the highest number of deaths among all cancers. Despite this, people still openly consume cigarettes, hookah, bidis, and vaping products, all of which gradually bring them closer to lung cancer.
Lung cancer is dangerous for several reasons, and multiple factors make it particularly lethal. Let's explore a few points to understand why lung cancer is so deadly:
The symptoms of lung cancer often appear very late, and by the time they do, the disease has already reached an advanced stage. In many cases, symptoms only become noticeable in the final stages, often after the cancer has spread to other organs.
The process of cancer spreading from one organ to another is called metastasis, and lung cancer is among the cancers that can spread quickly to other parts of the body.
As lung cancer progresses, it gradually affects the respiratory system. This leads to complications, making the condition even more serious over time.
According to Dr. Ayush Pandey, smoking has become very common today and is one of the leading causes of lung cancer. Tobacco and its smoke contain countless chemicals that can trigger cancer. These chemicals reach the lungs directly through inhalation, and over time, they can initiate the development of cancer in the lungs.
The difficulty of treating cancer depends, to some extent, on its location in the body. For example, skin cancer may be easier to treat than brain cancer. Similarly, treating lung cancer is very challenging, because the lungs are highly complex and sensitive organs, surrounded by other critical organs such as the heart.
Therefore, lung cancer treatment is considered relatively complicated. Patients whose cancer has reached an advanced stage face longer and more difficult treatment, and the success rate is lower in such cases. If you know someone battling lung cancer, it is advisable to consult a good and experienced oncologist.
To prevent lung cancer, quitting smoking is essential. If you use cigarettes, hookah, bidis, or vape, you should stop immediately. You can seek professional help from doctors to quit smoking. Additionally, minimize exposure to harmful chemicals, gases, and other pollutants. Keep your body active, eat a healthy diet, and drink plenty of water.
If a person has a family history of cancer siblings, parents, or close relatives it is important to consult a doctor regularly. Based on your family history, a doctor may advise regular check-ups after a certain age. Along with medical guidance, you may also receive important advice on maintaining a healthy lifestyle and diet.
