The risk of death from lung cancer is declining, but it must be detected early.

Lung cancer is a disease that occurs when you have an excess of malignant cells in this vital organ. In some cases, it also derives from other parts of the body when the disease is at an advanced stage and has spread to other organs (metastasis) until it affects the lung, even if the cancer is not directly involved.




Lung cancer is one of the most common today, according to the WHO (World Health Organization), in both men and women. It develops in the majority of the cases from the 50 years of age and is the cancer with more risk of death.

Symptoms of Lung Cancer

Symptoms that indicate the possibility of lung cancer are very similar to the symptoms of other more common and less dangerous diseases such as chronic bronchitis, influenza, respiratory problems, acute cough. The only difference is that these symptoms persist in time and are getting worse as the disease grows. Instead, symptoms similar to the disease cancer, do not last too much, they are cured in whole or appear intermittently rather persistently.

There is a high survival rate of lung cancer when detected earlier.

The most common symptoms of lung cancer are usually very general, here is the list:

• Cough or chest pain
• Respiratory Whistling
• Sputum with blood
• Acute hoarseness and/or lack of oxygen

Cough or chest pain. Cough is a clear symptom of lung cancer that reflects the discomfort of our throat, lungs or chest. In most cases it is the mildest symptom and least reflects the possibility of cancer, but it is a very obvious sign that something is happening in our body. The so-called "dog cough", aggressive and painful dog barking, is the one that best reflects the possibility of cancer.

Respiratory Whistling. When we breathe, cough or sleep and hear a spit of involuntary whistle denotes that in our lungs there is an excess of contaminated air or that the respiratory process is failing.

Sputum with blood. Spitting blood with mucus, saliva coming out of blood or making expectorations, is a clear example of that within your organism are appearing serious anomalies and/or ruptures or internal infections.

Acute hoarseness and/or lack of oxygen. Hoarseness or lack of oxygen when walking or practicing mild physical activity is a common problem, but if left untreated it can lead to lung cancer or another type of cancer.

If you feel any of these symptoms repeatedly or constantly or if you feel acute discomfort, go to your doctor to perform a specific check based on your ailments. These diseases, if detected early, have a high rate of cure and can lead to a completely normal life in the long run.

Causes of Lung Cancer

The causes that produce lung cancer are very diverse and disparate. There is a high percentage of cases in which, these causes derive in this disease, but do not necessarily result in cancer, but may be any other disease.

The most common causes of lung cancer are:

• Smoking
• Radon
• Genetic component

Smoking. Tobacco is one of the most common causes of lung cancer, although it affects all organs of the body very aggressively. It causes a high concentration of cancerous, harmful cells that accelerate in a remarkable way.

Smoking increases the chances of getting lung cancer

Radon. Radon is a highly radioactive gas that is released from things as common as soil or rocky materials. Being invisible and odorless, is a gas that is not perceived and therefore, it is very difficult to avoid its inhalation. More and more cases of lung cancer have been detected where molecules of this radioactive gas have been detected. A clear example of people exposed to radon are the miners, since the grit and dust that the rocks give off when they are chopped have a high content of this gas detrimental to health. Therefore, it is important that any person who is in constant contact with rocks is adequately protected to avoid an excess of toxic inhalations.

Genetic component. Any type of cancer can be a product of the genetics of the person, it may be that in your family there is a high percentage of people who have suffered and that passes from one generation to another, but like any other cause, has to occur necessarily, although there are other members of the family who have suffered. Even so, it is advisable that if in your direct family nearby (parents, siblings, grandparents) there are several cases of cancer, from the age of 30-35 will begin to perform annual tests to prevent or detect the lung cancer.

The main way to detect cancer, and especially to prevent it in time to act, is from a certain age (usually from 35 years) without distinction of sex, it is begun to make annual revisions to rule out any anomaly. With special interest those people who have had in their direct family cases of some type of cancer.

If you suffer from any of the symptoms mentioned above or in your day to day any of the causes that cause more lung cancer, you should see your doctor to keep track of these events that can be triggers of any cancer and in addition, may be the reason for other ailments derived from these routine habits. According to the WHO, cancer is the disease that most affects the entire world, but that the risk of death by lung cancer in science is decreasing.
