Hello

1
00:00:01.072 --> 00:00:03.793
I'm Kang Hyesun from the Department of Pulmonology at Bucheon St. Mary's Hospital

2
00:00:04.507 --> 00:00:08.031
I'm going to talk about lung cancer and asthma today

3
00:00:08.381 --> 00:00:10.420
Let me start with lung cancer

4
00:00:11.093 --> 00:00:14.720
What is lung cancer?

5
00:00:14.720 --> 00:00:18.855
Lung cancer is a malignant tumor in the lungs

6
00:00:19.344 --> 00:00:22.606
It's divided into primary and metastatic lung cancer.

7
00:00:22.860 --> 00:00:27.574
Primary lung cancer is lung cancer that occurs in the lungs or bronchial tubes

8
00:00:28.087 --> 00:00:32.142
Cancer that has spread to the lungs in other organs

9
00:00:32.468 --> 00:00:35.214
Especially the liver or large intestine

10
00:00:35.239 --> 00:00:39.005
Is called metastatic lung cancer. Generally speaking, lung cancer 

11
00:00:39.355 --> 00:00:42.148
Means primary lung cancer

12
00:00:43.022 --> 00:00:45.995
(Why Lung Cancer Is Dangerous)
Question four. Is lung cancer dangerous?

13
00:00:46.496 --> 00:00:50.346
Lung cancer, as you can see on this screen

14
00:00:50.346 --> 00:00:55.033
Is the fifth most prevalent among men and women

15
00:00:55.470 --> 00:00:57.446
At the 2015 data

16
00:00:57.930 --> 00:01:02.523
If you look at the second screen, despite this high prevalence

17
00:01:02.873 --> 00:01:08.791
It has a very low survival rate compared to other types of cancers such as stomach cancer and colon cancer

18
00:01:09.252 --> 00:01:14.942
And if you look at the third slide, there's a distribution of stages at the time of lung cancer diagnosis

19
00:01:15.226 --> 00:01:19.352
The graph on the upper left shows stage 1 of the light period

20
00:01:19.377 --> 00:01:22.971
So that means early lung cancer, and the graph below

21
00:01:23.321 --> 00:01:27.557
shows the distribution of stage 4 lung cancer 

22
00:01:27.582 --> 00:01:32.348
The diagnosis rate of early lung cancer at the time of diagnosis of lung cancer is only about 20%

23
00:01:32.706 --> 00:01:37.023
And 40% of lung cancer cases have already progressed to the stage 4 at the time of diagnosis

24
00:01:37.291 --> 00:01:41.013
As with other cancerous tumors

25
00:01:41.038 --> 00:01:43.997
It is often diagnosed after a considerable progression, so the prognosis is worse

26
00:01:44.670 --> 00:01:47.011
Is lung cancer contagious?

27
00:01:47.036 --> 00:01:51.844
Lung cancer is not an infectious disease like pneumonia or tuberculosis

28
00:01:52.573 --> 00:01:55.993
Is lung cancer hereditary?

29
00:01:56.018 --> 00:02:00.324
It is known that family history is important for lung cancer

30
00:02:00.523 --> 00:02:03.999
The risk of lung cancer is two or three times higher

31
00:02:04.024 --> 00:02:07.917
Than that of those who have no family history

32
00:02:08.219 --> 00:02:10.600
However, so far

33
00:02:10.625 --> 00:02:15.661
No genetic test method has been proven to identify lung cancer in advance

34
00:02:16.051 --> 00:02:21.399
So it is recommended to perform high-resolution tomography periodically

35
00:02:21.424 --> 00:02:23.572
To detect it early if you are a high-risk lung cancer group or especially a smoker

36
00:02:24.596 --> 00:02:28.032
What is the average age group for lung cancer?

37
00:02:28.057 --> 00:02:32.705
The most common age group for lung cancer is in their 60s, accounting for 38%

38
00:02:33.070 --> 00:02:36.226
Followed by in their 70s, and then in their 50s

39
00:02:36.251 --> 00:02:39.211
Which is mainly cancer for the elderly

40
00:02:40.132 --> 00:02:44.181
Can non-smokers get lung cancer, too?

41
00:02:44.206 --> 00:02:47.641
While 70 percent of all lung cancer patients are smokers

42
00:02:47.728 --> 00:02:52.631
The remaining 30 percent are non-smokers

43
00:02:52.656 --> 00:02:58.655
In particular, in the case of female lung cancer patients, it was confirmed that more than 80% of all patients had no smoking experience

44
00:02:58.680 --> 00:03:01.915
Why do these patients get lung cancer?

45
00:03:01.940 --> 00:03:04.405
Some people ask

46
00:03:04.430 --> 00:03:05.920
Why they get lung cancer even though they are non-smokers

47
00:03:05.945 --> 00:03:10.397
Secondhand smoking, smoke

48
00:03:10.422 --> 00:03:16.710
Indoor air pollution caused by raw materials, radon exposure, and chronic infectious diseases with existing lung diseases

49
00:03:16.743 --> 00:03:20.653
Pneumonia, and tuberculosis are also known to date

50
00:03:21.010 --> 00:03:23.875
It is known to cause a higher risk of lung cancer

51
00:03:24.169 --> 00:03:28.923
What is the risk factors for lung cancer?

52
00:03:28.984 --> 00:03:32.198
It overlaps a lot with the previous questions

53
00:03:32.611 --> 00:03:34.926
the biggest factor of lung cancer is smoking

54
00:03:35.292 --> 00:03:38.117
as I told you, the cause of non-smoking lung cancer is

55
00:03:38.142 --> 00:03:43.543
indirect exposure, indoor air pollution quartz radiation radon 

56
00:03:43.901 --> 00:03:47.567
and existing inflammatory lung disease and genetic factors

57
00:03:48.375 --> 00:03:51.398
this is the general information about lung cancer

58
00:03:51.621 --> 00:03:55.557
as the highest risk factor of lung cancer is smoking

59
00:03:55.865 --> 00:03:59.055
in case of smoking, making an early discovery

60
00:03:59.080 --> 00:04:01.801
is important in treating lung cancer

61
00:04:02.325 --> 00:04:05.865
So if you are in a high-risk group of lung cancer

62
00:04:05.890 --> 00:04:09.682
a low-dose CT scanning is recommended for early detection

63
00:04:10.302 --> 00:04:11.032
Thank you
