65-year-old Lao Liu is an old smoker. Recently, two “smokers” around him for decades passed away due to lung cancer. Other smokers were so frightened that they quit smoking. , I have always been in good health, and I don’t have any serious illnesses at ordinary times, so I don’t listen to advice.
But in a recent physical examination, CT showed a lesion in Lao Liu’s right lung, which was diagnosed as early lung cancer after biopsy, which scared him.
Lao Liu said,It is true that his fingers have only gradually become thicker in the past year., but it didn’t hurt or itch, so I didn’t care about it, thinking it was just too much rough work. The doctor explained that this is a typical sign of finger clubbing, and it is also a common sign of lung cancer. If it can be detected early, the arrival of lung cancer may be avoided.
Fortunately, Lao Liu is now in the early stage of lung cancer, and he is actively treated, and the cure rate is relatively high.
So, what is this clubbing and why can it be a sign of lung cancer? Besides clubbing, what other signs and symptoms may suggest lung cancer?
Many people think that the only symptoms of lung cancer are cough and hemoptysis, but this is wrong. The etiology of lung cancer is complex, and the symptoms and signs of each person are different.
In general, the symptoms of lung cancer are diverse, the most common are respiratory and chest symptoms, such asCough, blood in sputum, hemoptysis (common in central lung cancer), chest pain, fever, dyspneawait.
But there are also many people who present with extrapulmonary or extrathoracic symptoms, such asHoarseness, shoulder pain, headacheCervical sympathetic syndrome or superior vena cava syndrome.
Among them, the most easily overlooked is the thickened and swollen ends of the fingers, which is the “clubbing” mentioned in the previous case.
Clubbing finger is also called mallet finger, as the name suggests,That is, the end of the finger or toe is thickened and swollen, becoming like a mallet。
It is not a disease itself, but a disease characteristic, so the pathogenesis is not yet clear, but it is generally believed to be related toChronic hypoxia at the extremities, arterial blood oxygen deficiency, metabolic disorders, toxic injury and increased blood flowand other factors.
In the early stage of lung cancer, the patient may experience clubbing due to the lack of oxygen in the lung lesions, resulting in the expansion of peripheral blood vessels and soft tissue hyperplasia.
Clinical statistics have found that clubbing has a certain relationship with diseases in various systems of the body.only75%~80% are related to respiratory diseasessuch as chronic bronchiectasis, pulmonary metastatic tumors, lung abscess, pulmonary cystic fibrosis, diffuse pulmonary interstitial fibrosis pneumoconiosis, pulmonary arteriovenous malformation, open pulmonary tuberculosis, etc.
In addition there are10%~15% may be cardiovascular diseaseIf clubbing occurs in children aged 2-3, it is mostly congenital heart disease; young and middle-aged people are mostly subacute infective endocarditis; elderly people are mostly considered to be chronic pulmonary heart disease.
besides5%~10% are related to digestive system diseasessuch as chronic inflammatory bowel disease, liver cirrhosis, Crohn’s disease, intestinal tuberculosis, etc.
also,Syphilis, chronic nephritis, hyperthyroidismIt may also be associated with clubbing.
In fact, it is very simple to distinguish clubbing fingers. Come on, everyone stretch out your hands with me.
Let’s take a look at the angle of our thumb base first: the normal thumb base angle is less than 180°,The thumb base angle of the clubbing finger is generally equal to or greater than 180°a significant deformation can be seen.
Secondly, you can also touch the end of the finger and gently press the nail. If the proximal nail base tissue feelsNails appear to rest on sponge pads and are easily depressedit may be clubbing.
Once you find that you have clubbing, it is recommended to go to the hospital as soon as possible to find out the cause. Screening items generally include:Routine biochemistry, chest X-ray examination, CT, electrocardiogram, arterial blood gas analysiswait.
If other causes are ruled out after examination, it is only natural familial clubbing, and generally no special treatment is required. If it affects the appearance, soft tissue excision at the end of the finger can be considered to correct the deformity.
If other incompatibility is found, symptomatic treatment is required.Especially for middle-aged and elderly patients who have been smoking for a long timeEven if the respiratory symptoms are not obvious, you should be highly vigilant when you find clubbing.
There is currently no preventive method for clubbing, but most are associated with heart and lung disease. Therefore, nourishing the heart and lungs daily can reduce the chance of clubbing.
When tobacco is burned, there are many carcinogens and harmful substances, which can cause direct damage to the lungs after inhalation, and even induce cancer.
A cohort study of 550,000 people in the JAMA sub-journal showed that,Continuous smokers have a 180% increased risk of all-cause mortalityand the earlier the smoking cessation, the smaller the risk increase, and the cessation of smoking before the age of 35 can offset a large number of death risks!
At the same time, smoking cessation can improve the ventilation function of the lungs, increase the amount of oxygen in cardiomyocytes, and reduce the risk of heart disease.
Therefore, smokers should quit smoking as soon as possible, and non-smokers should also avoid second-hand smoke, third-hand smoke, kitchen fumes, and air pollution.
Aerobic exercise can enhance lung capacity and myocardial ejection volume, thereby improving cardiopulmonary function.We can choose some aerobic exercises that suit us according to our own conditions, such asJogging, skipping rope, swimmingwait.
Nourishing the lungs and protecting the heart can be combined with diet,Tremella, Lily, Lotus Seed, SydneyIt has the effect of moistening the lungs and clearing away heat, so it is a good diet therapy for nourishing the lungs.andbroccoli, eggplant, black beans, onions, almondsAnd so on are famous “heart-protecting” foods, and cardiovascular patients can also eat more.
Long-term staying up late and irregular sleep will reduce the body’s immunity, leading to a decrease in lung resistance and susceptibility to external bacterial and viral infections. Once the body has respiratory inflammation, it is easy to develop into pneumonia. If you are a smoker, smoking at night has a greater impact on your lungs.
In Chinese medicine, going to bed early and getting up early is in line with the harmony of yin and yang, which can better stretch the lung qi,The best time of the day to nourish the lungs is 7:00~9:00 in the morningAt this time, aerobic exercise can also get twice the result with half the effort.
In addition, a study published in the “European Heart Journal-Digital Health” of the European Society of Cardiology by researchers from the University of Oxford and the University of Exeter in the United Kingdom showed that sleeping between 10 pm and 11 pm was associated with lower People who go to bed at midnight or later are at the highest risk, so going to bed early and waking up early is important for cardiorespiratory health.
Everyone remember to observe your fingers more. If you have clubbing signs, you must be vigilant. Don’t miss the early warning given by your body. Early detection and early treatment. At the end of the article, click to read and tell more people~
