0 00:00:00.125 --> 00:00:00.725 Hello 1 00:00:00.725 --> 00:00:04.075 I'm Kang Hyesun from the Department of Pulmonology at Bucheon St. Mary's Hospital 2 00:00:04.325 --> 00:00:08.325 Today I'll be taking about information related to diagnosis of lung cancer 3 00:00:08.325 --> 00:00:13.826 Symptoms of Lung Cancer 4 00:00:13.826 --> 00:00:17.126 Symptoms of lung cancer vary depending on where lung cancer occurs 5 00:00:17.126 --> 00:00:21.426 So depending on the pattern of metastasis in the bronchial tubes or other body parts 6 00:00:21.426 --> 00:00:24.276 The symptoms may vary 7 00:00:24.676 --> 00:00:28.377 In general, some people are asymptomatic when diagnosed 8 00:00:28.377 --> 00:00:31.227 And it could be often diagnosed through examination 9 00:00:31.577 --> 00:00:35.977 If you have symptoms, the most common symptom is coughing 10 00:00:36.377 --> 00:00:40.777 It can be accompanied by non-specific symptoms such as hemoptysis, loss of appetite, weight loss, fatigue, chest pain 11 00:00:41.027 --> 00:00:44.828 Or weakness, etc 12 00:00:45.378 --> 00:00:49.878 Symptoms by Stage of Lung Cancer Progression 13 00:00:50.278 --> 00:00:52.778 Early lung cancer may have no symptoms 14 00:00:53.228 --> 00:00:57.928 Even advanced lung cancer may have different symptoms depending on the organ involved 15 00:00:57.928 --> 00:01:02.879 If it occurs in the airway, it may cause symptoms of wheezing due to airway obstruction 16 00:01:03.329 --> 00:01:06.629 The bronchus narrows and can cause pneumonia 17 00:01:07.029 --> 00:01:10.129 Patients may experience coughs, fevers, chest pains etc 18 00:01:10.529 --> 00:01:14.429 If the cancer has progressed to the chest wall, chest pain can occur 19 00:01:14.829 --> 00:01:18.330 In the case of pleura, pleural effusion 20 00:01:18.530 --> 00:01:19.980 May cause breathing difficulties 21 00:01:19.980 --> 00:01:23.130 Also, if it invades a particular nerve located in the neck 22 00:01:23.480 --> 00:01:27.830 It can also occur Horner syndrome, where your eyelids droop and your pupils get smaller 23 00:01:28.180 --> 00:01:34.681 However, the symptoms vary greatly depending on each stage of progress, so it's hard to say all together 24 00:01:34.931 --> 00:01:37.081 But if there's a metastasis in the brain 25 00:01:37.481 --> 00:01:40.831 It can make you clumsy with words or lose your ability to move your arms and legs 26 00:01:40.831 --> 00:01:45.381 It can also cause serious symptoms that can affect the quality of life 27 00:01:45.781 --> 00:01:50.032 Can lung cancer be detected early? 28 00:01:50.032 --> 00:01:54.232 So far, the most proven way to detect lung cancer early 29 00:01:54.782 --> 00:01:57.632 Is if you are a smoker and have a family history 30 00:01:58.282 --> 00:02:01.982 A low-dose chest CT scans are the only way 31 00:02:02.282 --> 00:02:06.683 As I said, lung cancer increases with age 32 00:02:07.283 --> 00:02:12.083 If you are 55 or older and have a smoking history of 30 years or more 33 00:02:12.483 --> 00:02:15.933 We have lung cancer screening in Korea 34 00:02:16.533 --> 00:02:20.983 Even if you're not subject to lung cancer screening, if you have a history of smoking 35 00:02:20.983 --> 00:02:24.484 Or have a family history, you're at risk for lung cancer 36 00:02:24.984 --> 00:02:28.234 Getting a low-dose CT scans at intervals of one to two years 37 00:02:28.384 --> 00:02:32.684 Helps detect early development of lung cancer 38 00:02:32.984 --> 00:02:36.434 The Harmfulness of Smoking 39 00:02:37.484 --> 00:02:39.885 More than 70% of lung cancer patients are smokers 40 00:02:40.135 --> 00:02:43.435 Smoking is the most potent risk factor for lung cancer 41 00:02:44.035 --> 00:02:47.085 Therefore, quitting smoking is the most important thing in preventing lung cancer 42 00:02:47.335 --> 00:02:52.685 Even if you have lung cancer, quitting smoking is a way to increase your response to treatment 43 00:02:53.135 --> 00:02:55.735 If you look at the risk of lung cancer during non smoking period for smokers 44 00:02:56.186 --> 00:02:59.436 If you quit smoking for 15 years, compared to current smokers 45 00:02:59.686 --> 00:03:04.186 It's known to reduce the incidence of lung cancer by 75% 46 00:03:04.736 --> 00:03:07.436 The longer you quit smoking, the more you can prevent lung cancer 47 00:03:07.436 --> 00:03:09.886 so please keep that in mind 48 00:03:10.786 --> 00:03:18.337 Lung Cancer Testing and Diagnosis Method at Bucheon St. Mary's Hospital 49 00:03:18.337 --> 00:03:20.837 In our hospital to diagnose lung cancer, a low-dose of chest CT scan 50 00:03:20.837 --> 00:03:24.837 And to assess malignant tumor metastasis, a whole-body PET scan 51 00:03:25.137 --> 00:03:27.837 And head MRI, and bone scan is performed 52 00:03:28.237 --> 00:03:34.288 For histological diagnosis, a Bronchoscopy and percutaneous CT-guided lung biopsy are performed 53 00:03:34.588 --> 00:03:39.388 In particular, lymph nodes are very important in determining how to treat it 54 00:03:39.638 --> 00:03:44.488 And through ultrasound bronchoscopy, if necessary, Staging of lymphoma is also performed 55 00:03:45.688 --> 00:03:47.939 So that was some information regarding lung cancer diagnosis 56 00:03:47.939 --> 00:03:52.239 Prevention is more important than diagnosis for lung cancer 57 00:03:52.239 --> 00:03:54.589 So I want to emphasize that you should quit smoking 58 00:03:54.789 --> 00:03:56.639 If you haven't quit smoking yet 59 00:03:56.639 --> 00:04:00.839 Or if you're a high-risk lung cancer patient with a long smoking period 60 00:04:01.089 --> 00:04:06.840 We recommend that you do a low-dose chest CT scan regularly 61 00:04:06.840 --> 00:04:07.540 Thank you
