We can often go without recognizing the danger, just because we do not know anything about it. Provided that you learn some essential lung cancer facts, you will know more about the condition, its spread and severity. Hopefully, this helpful information will allow you to recognize and see the threat more clearly. In turn, you will have the confidence and willpower to take measures for prevention.
Lung cancer causes the largest number of cancer deaths. The statistics show that this disease causes the death of approximately 175,000 people every year in the US only. However, this is not due to the lack of prevention. In fact, according to the medical and scientific community, it is the most preventable of all types of cancer.
It has been estimated that 250,000 people are diagnosed with the condition each year in the United States alone. Statistical data shows that most sufferers are 40 to 70 years of age. The patients, who are younger than 30, are about 1% of all sufferers. The ones over the age of 70 are approximately 10% of all patients.
There are 20 types of tumors that can grow in the lungs. The most common types have been divided into 2 groups – non-small cell cancer and small cell cancer. There are three subtypes of the non-small cell cancer. The large-cell carcinomas affect between 10% and 15% of all patients. The squamous cell carcinoma affects around 30% of all patients. The adenocarcinoma is the most common type of lung cancer that accounts for 40% of all cases of the condition.
The small-cell cancer is the most aggressive type of all, even though it is not as common as the other types. The statistics show that around 75% of all patients with this condition have metastasizes, spread of the tumor, at the time of diagnosis.
85% to 90% of all cases of the condition are caused by smoking. This included second-hand smoking. People who smoke a pack of cigarettes per day are 20 times more likely to develop lung cancer than non-smokers. If you smoke two packs per day, the risk is over 30 times higher. If you are a second-hand smoker your risk increases 2 to 3 times.
The number of people who live for 5 years after being diagnosed with lung cancer is 15% of all diagnosed. It has been estimated that this percentage will increase by 1% every year.
