Built-up in the body over a long period of time, smoking caused cancers have distinct stages that peak in smokers between the ages of 55 years and 65 years old. Smoking causes almost immediate changes within the lungs, shortly after they have come into contact with carcinogenic chemicals (chemicals that cause cancer). Soon after their first exposure, abnormal cells begin to appear within the main breathing tubes. These cells are accelerated in growth through the continued exposure to these dangerous chemical substances (caused through smoking). Some of these cells will become cancerous and others will form into small tumors.
There are two Main Types of Lung Cancer
The first is Non-Small Cell Cancer that consists of three different types: Squamous Cell Carcinoma, Ademocarcinoma and Large Cell Carcinoma.
The second is Small Cell Cancer, also referred to as (Oat Cell Cancer). This is a faster spreading cancer than the Non-Small Cell type and is usually contributed to over 20% of all lung cancer cases.
Key Facts about Lung Cancer
1. It is the most commonly diagnosed cancer in the world, with more than 1.8 million cases diagnosed every year.
2. The highest rate of detection for men is in Central and Eastern Europe, while for women the highest rate of detection is in North America. The lowest rate of detection can be found within the Middle African Countries.
3. It is the second most diagnosed cancer in men after prostate cancer, with around 215,000 new cases being diagnosed every year in the USA, and around 25,000 new cases being diagnosed every year in the United Kingdom.
4. Of the 215,000 new cases which are diagnosed every year in the USA, around 85% will die within the first five years of diagnoses.
5. Current or former cigarette smokers make up for over 80% of all lung cancer deaths in both men and women over the age of 55 years, and is on the rise.
6. Smoking is the cause of over 25% of all cancer deaths in the world, with over 32% of deaths occurring in men, and 25% in women.
7. Every year a higher percentage of men are diagnosed with lung cancer than women.
8. A man who smokes up to two packets of cigarettes a day, has more than 25 times higher risk of being diagnosed with cancer than a non-smoker.
9. Cancers mortality rate can be heavily reduced through its early detection and treatment.
10. It is never to late to stop smoking as within the first 30 minutes of smoking the last cigarette the bodies organs begin to benefit.
