Lung cancer is the leading reason for cancer fatality and is the main cause of cancer connected fatalities globally, accountable for 1.3 million deaths every year.  It's the largest cause of death in both males and females related to cancer in America today.

Worryingly it is the 2nd most frequent cancer among both ladies and men, 2nd to breast and cancer of the prostate respectively.  It is the most common cancer worldwide but surprisingly one of the easiest to prevent as it is usually caused by smoking.  The disease is caused by the uncontrolled growth of abnormal cancer cells in  either of the lungs that is characterized by the presence of malignant tumours.

It is the leading cancer killer among Caucasians, African Americans, Asians and Hispanic males and kills more than 160,000 people a year, and so it is no surprise to know that it is a serious health problem that affects many people and their families.  Lung cancer is the second most common cancer in the US and utilizes a vast proportion of health care resources.

The disease is the only known effect on human health from exposure to radon in air.  It can either arise in the lung itself or it may be a cancer in the airway, called the bronchus.  It can be noticed on a chest radio graph also called CT Scan and is usually first discovered  through such a scan.  It  is often known to be diagnosed from a chest x-ray done for another condition.

The disease is one of the largest causes of death due to cancer.  It is caused by abnormal cells multiplying and growing into a tumor which is difficult to manage, and prevent using current surgical and medical approaches.

Lung cancer has changed in type over the last 30 years.  It has very high morbidity and mortality with only a fraction of patients surviving after five years.  It is difficult to treat unless it is found at very early stages and has been known to spread into other organs of the body and speed the demise of the patient.

Treatment depends upon the stage of the cancer and on a number of factors, including the type of lung cancer (non-small or small cell lung cancer), the size, location and extent of the tumor, and the general health of the patient.  Treatment may include surgery, chemotherapy, and radiation.

Symptoms include acute dyspnoea, tachypnea, chest pain, fever, dizziness, sensory changes, and of course a lingering smokers cough.
