This year, more than 310,000 adults all over Europe will be diagnosed with lung cancer.
Lung cancer is literally the biggest cancer killer worldwide – causing more deaths than breast and prostate cancer put together all over the world. To sum it up every 30 seconds, someone, somewhere in the world dies of lung cancer.
The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Presently it’s approximated at 18 %; respectively 15 % for men, 21 % for women. Not surprisingly, lung cancer has the lowest 5-year survival rate of the other most common cancers: only 18 %, versus prostate at 99 %; breast at 89 %; and colorectal at 65 %.
Facts about lung cancer in Ireland
Lung cancer is one of the most common cancers affecting both men and women in Ireland.
- About 2,300 Irish people are diagnosed with lung cancer every year.
- Lung cancer is the fourth most common cancer in Ireland after prostate, breast and colorectal.
- The incidence of lung cancer is currently increasing in Ireland in both men and women due to advancing age, better detection and a reflection of historical smoking trends.

- With an average of 1800 deaths each year in Ireland, lung cancer is the leading cause in cancer death in both men and women in Ireland
- The majority of people who get lung cancer are over the age of 50. Approximately eight of every ten lung cancer cases are due to smoking.

About lung cancer
What are the lungs?
The lungs are two organs found in your chest and form part of your respiratory system. This system is responsible for your breathing. The right lung is slightly bigger than the left and contains three areas called lobes. The left lung contains two lobes.
When you breathe in, air passes through your nose or mouth into your trachea (windpipe) and separates into two further tubes (bronchi). Each of these bronchi connects to a lung.
The bronchi divide even further into much smaller tubes called bronchioles. Air passes through these bronchioles and into tiny air sacs called alveoli. In the alveoli, oxygen is absorbed from inhaled air into your bloodstream and is sent around your body.
Oxygen is needed in every cell of your body for various activities. During these activities, the waste gas, carbon dioxide, is made. It passes back through the alveoli and leaves your body when you breathe out.
What is lung cancer?
When cancer develops in the lungs, the cells change and grow in an abnormal way. Many lung cancers begin in the wall of the bronchi. As the cancer grows it forms a collection of cells (tumour). This tumour can then cause a blockage and result in symptoms, for example, difficulty in breathing.
How common is lung cancer?
Lung cancer can occur in men and in women. In Ireland it is the fourth most common cancer after prostate, breast and bowel cancers.
About 2,300 Irish people are diagnosed with lung cancer every year. Sadly, more Irish men and women die from lung cancer than any other type of cancer.
