What is the Symptoms of Lung Cancer and What are its Causes 

Lung cancer happens when malignant cells are formed in the tissues of the lung. It is the leading cause of cancer death in the world. The incidence of lung cancer has been increasing since the early 20th century.  

The most common symptoms of the disease are cough, chest pain, and breathing difficulty. But the symptoms are often vague and can also be caused by less serious health problems. That’s why it’s so important for everyone to know what is lung cancer and the signs and symptoms of lung cancer. If you have chest pain, constant cough, shortness of breath, or other symptoms, see your doctor. 

Causes of Lung Cancer 

Lung cancer is usually a long-term (chronic) condition that develops slowly over time. The most common symptoms of lung cancer are a persistent cough, breathlessness, pain when breathing, and weight loss. There are several possible causes of lung cancer.  

Some of the causes of lung cancer include smoking. You are more likely to develop lung cancer if you smoke or if you are exposed to secondhand smoke, radon gas, environmental pollution, asbestos, and air pollution. 

Lung cancer is the most common type of cancer in the world. More than 1.6 million new lung cancer cases are diagnosed each year, and nearly 1.5 million people die from it annually. It is not a rare disease, as many people think. But if you want to know about the causes of lung cancer, it’s not always easy to find the answer on the Internet. 

Lung Cancer Symptoms 

Coughing up blood, also known as hemoptysis, is the medical term for coughing up blood from the respiratory tract. This can occur from the lungs, the airways, or the throat. Coughing up blood is a symptom of lung cancer, especially if you are a smoker.  

People who smoke are more likely to develop lung cancer than those who do not. Smoking causes cancer by damaging the cells in your lungs that help to fight the disease. The higher your tobacco use, the higher your risk of developing lung cancer.  

Most lung cancer deaths occur in patients who smoke heavily over many years, but some lung cancers can develop in nonsmokers, especially in people exposed to secondhand smoke or asbestos. 

Shortness of breath is a symptom of lung cancer, especially with the appearance of a tumor in the lungs. If you live in a place where the air is polluted or you are a heavy smoker, you should be more aware of your health.  

With the development of lung cancer, there may be a terrible cough, weakness, nausea, and vomiting. At the same time, there may be a pain in the chest, shoulder, neck, and back. In addition, there may be a feeling of tightness in the throat, while a person may not be able to swallow.  

There may also be a sensation of a lump in the throat. Shortness of breath is a symptom that should not be ignored. If you have difficulty breathing, do not try to suppress your feelings, contact a doctor.
