Hello
I'm Kang Hyesun from the Department of Pulmonology at Bucheon St. Mary's Hospital
I'm going to talk about lung cancer and asthma today
Let me start with lung cancer
What is lung cancer?
Lung cancer is a malignant tumor in the lungs
It's divided into primary and metastatic lung cancer.
Primary lung cancer is lung cancer that occurs in the lungs or bronchial tubes
Cancer that has spread to the lungs in other organs
Especially the liver or large intestine
Is called metastatic lung cancer. Generally speaking, lung cancer
Means primary lung cancer
(Why Lung Cancer Is Dangerous) Question four. Is lung cancer dangerous?
Lung cancer, as you can see on this screen
Is the fifth most prevalent among men and women
At the 2015 data
If you look at the second screen, despite this high prevalence
It has a very low survival rate compared to other types of cancers such as stomach cancer and colon cancer
And if you look at the third slide, there's a distribution of stages at the time of lung cancer diagnosis
The graph on the upper left shows stage 1 of the light period
So that means early lung cancer, and the graph below
shows the distribution of stage 4 lung cancer
The diagnosis rate of early lung cancer at the time of diagnosis of lung cancer is only about 20%
And 40% of lung cancer cases have already progressed to the stage 4 at the time of diagnosis
As with other cancerous tumors
It is often diagnosed after a considerable progression, so the prognosis is worse
Is lung cancer contagious?
Lung cancer is not an infectious disease like pneumonia or tuberculosis
Is lung cancer hereditary?
It is known that family history is important for lung cancer
The risk of lung cancer is two or three times higher
Than that of those who have no family history
However, so far
No genetic test method has been proven to identify lung cancer in advance
So it is recommended to perform high-resolution tomography periodically
To detect it early if you are a high-risk lung cancer group or especially a smoker
What is the average age group for lung cancer?
The most common age group for lung cancer is in their 60s, accounting for 38%
Followed by in their 70s, and then in their 50s
Which is mainly cancer for the elderly
Can non-smokers get lung cancer, too?
While 70 percent of all lung cancer patients are smokers
The remaining 30 percent are non-smokers
In particular, in the case of female lung cancer patients, it was confirmed that more than 80% of all patients had no smoking experience
Why do these patients get lung cancer?
Some people ask
Why they get lung cancer even though they are non-smokers
Secondhand smoking, smoke
Indoor air pollution caused by raw materials, radon exposure, and chronic infectious diseases with existing lung diseases
Pneumonia, and tuberculosis are also known to date
It is known to cause a higher risk of lung cancer
What is the risk factors for lung cancer?
It overlaps a lot with the previous questions
the biggest factor of lung cancer is smoking
as I told you, the cause of non-smoking lung cancer is
indirect exposure, indoor air pollution quartz radiation radon
and existing inflammatory lung disease and genetic factors
this is the general information about lung cancer
as the highest risk factor of lung cancer is smoking
in case of smoking, making an early discovery
is important in treating lung cancer
So if you are in a high-risk group of lung cancer
a low-dose CT scanning is recommended for early detection
Thank you
