Lifestyle Factors That Cause Lung Cancer

Lung cancer is a leading cause of cancer deaths worldwide. Though many advancements have been made in improving its treatment, taking preventive measures is still the best option. Although smoking is the primary culprit, which we all know, many other factors also contribute to it.

These factors include secondhand smoke, air pollution, and a poor diet. So, without beating around the bush, let’s go straight to the lifestyle risk factors for lung cancers and know what you can do to reduce your risk.

What is Lung Cancer?

Lung cancer refers to the growth of malignant cells in the lungs, the two spongy organs in the chest that control breathing. Usually, it produces symptoms in the advanced stage.

Here are the common symptoms of lung cancer:

• Persistent cough (Sometimes coughing up blood)
• Chest pain
• Shortness of breath
• Wheezing
• Hoarseness

Lifestyle Factors That Raise Risk of Lung Cancer

There are many risk factors for lung cancer beyond just smoking. Let’s know them one by one:

Smoking

Undoubtedly, tobacco is the real villain, not just for lung cancer but for many other conditions, too. Almost 9 out of 10 cases of lung cancer are due to tobacco smoking. Cigarettes, cigars, beedis, and even lighter versions have many cancer-causing chemicals that go straight to the lungs. But quitting works. It reduces the risk of lung cancer over time. 

Secondhand Smoke

If you are a nonsmoker, it doesn’t mean you are not at risk; even secondhand smoke is injurious. If you spend a significant amount of time with someone who smokes, you also breathe in those chemicals that raise your risk of developing lung cancer. Secondhand smoke is associated with a 24% higher risk in individuals who have never smoked. 

Children who are often exposed to secondhand smoke are more vulnerable. So, encouraging your near and dear ones and others to quit smoking can do wonders for everyone. 

Air Pollution

In cities like Delhi or other, breathing is like smoking many cigarettes a day, especially during the winter season. Microscopic pollutants present in the air can badly affect the lungs and cause inflammation and cell damage over time. Thus, it increases the risk of lung cancers and chronic lung diseases. So, as a responsible citizen, follow measures like using public transport to improve air quality.

Poor Diet

“We are what we eat” - we have heard this since childhood. But how many of us have really paid attention to it? This is really an important factor, and we all should take it seriously. Eating healthy and nutrient-rich foods like fruits and vegetables can help combat cellular damage and support lung tissue repair. 

Physical Activity

Someone rightly said that movement is medicine. So, include exercise or some kind of physical activity in your routine. 45 minutes of brisk cardio a day is enough. Regular exercises or yoga not only improve your muscles and strength, but it also strengthens your lungs. 

Don’t Ignore Your Symptoms

Lung cancer or any other chronic lung problem doesn’t develop overnight. So, keep a watch on yourself. If you notice anything abnormal, don’t ignore or self-diagnose using online sources; consult a doctor and immediately address the underlying cause.
