Is lung cancer contagious after physical examination? Lung cancer patients should pay attention to 5 things

Is it contagious to use the same bowls and chopsticks with lung cancer patients? There is no relevant evidence on the Internet, so it is better to consult a doctor. However, in daily life, many people are worried that eating with cancer patients will be contagious, so they use special bowls and chopsticks for cancer patients. In fact, some malignant tumors such as cancer are not contagious, and there is no problem with daily contact with cancer patients such as eating and shaking hands, so people don’t need to worry too much.

2. How is lung cancer detected?

2.1. Lung cancer examination: Sputum examination for cancer cells is a convenient, rapid, non-invasive examination that is easy to implement and apply. Once cancer cells are found in sputum, the diagnosis can be confirmed, so it has diagnostic value. Lung cancer examination is particularly suitable for the early diagnosis of lung cancer in the central part of the lung.

2.2. Fiberoptic bronchoscopy: Lung cancer examination is particularly suitable for sputum positive for cancer cells, while chest CT is negative. In addition, the diagnosis rate of lesions near the hilum of the lung is relatively high. Fiberoptic bronchoscopy can be combined with fine needle puncture, X-ray-guided lung biopsy, etc. to further improve the positive rate.

2.3 Low-dose spiral CT examination of the chest: Lung cancer examination can detect tiny lesions that cannot be found by conventional chest X-rays. Some foreign studies have shown that the use of low-dose spiral CT to screen lung cancer can significantly improve the detection rate of early lung cancer. After surgical treatment, most patients with lung cancer can be cured and live long-term. Special attention should be paid to ground-glass lesions and small nodular lesions on CT, which may be more significant than chest X-rays in the past.

3. What is the cause of lung cancer recurrence?

3.1. After some patients undergo lung cancer surgery, due to incomplete treatment, many residual cancer cells remain, which easily leads to recurrence. In order to reduce the recurrence of small lesions, it is recommended that when some cancer cells accumulate in the patient's body, other methods must be used in conjunction with surgical treatment, such as chemotherapy and radiotherapy, to reduce small lesions and residual cancer cells.

3.2. The second reason for the recurrence of lung cancer is that many patients become lax during the treatment process, resulting in failure to take medication on time, or give up treatment because they cannot tolerate the medication, which makes recurrence more likely.

3.3. The recurrence of lung cancer is related to bad living habits, especially eating habits. Therefore, to prevent the recurrence of lung cancer, you should avoid fried, pickled, and smoked foods and be careful about lung cancer caused by these foods.

1. Balanced diet: Eat small and frequent meals

One type of food alone cannot play an anti-cancer effect, but if they are reasonably combined, the effect will be completely different. For lung cancer patients, the medical community currently advocates a balanced diet, eating small meals frequently, and eating until 80% full at each meal.

2. Eat 5 servings of fruits and vegetables every day

Fresh vegetables and fruits contain a lot of vitamins and phytonutrients. Choose more red, orange, and dark green vegetables, and pair them with edible mushrooms that can increase immunity. Lung cancer patients can eat more tomatoes, citrus, loofah, strawberries, grapes, green peppers, asparagus, eggs, chicken liver, beans, spinach, lettuce, etc.

3. Eat less sugar

Patients with poor lung function should not eat purely sweet foods. They can choose a high-fat, low-carbohydrate diet to help reduce the respiratory burden.

4. Nutritional supplement

Oral supplementation of enteral nutrition preparations and products, such as enteral nutrition powder for lung disease, whole-vegetarian powder, yogurt, whey protein powder, and multivitamins, can help improve the nutritional status of lung cancer patients.

1. Quit smoking. Inhaling cigarette smoke irritates the respiratory tract and causes coughing, shortness of breath, and a variety of lung diseases, such as COPD and lung cancer. Smoking can make asthma more difficult to control. Quitting smoking can prevent further aggravation of COPD, improve asthma control, and reduce the risk of lung cancer.

2. Exercise. Regular exercise can also alleviate the condition to a certain extent and exercise the body. For example, 30 minutes of brisk walking every day can reduce the feeling of shortness of breath and relieve the symptoms of early lung disease.

3. Diet: Healthy diet should be a part of daily life. It is recommended to have 3-4 meals a day, including appropriate amounts of fruits and vegetables.

4. Vaccinations: Colds or other lung infections are more dangerous for people with respiratory diseases. If you have difficulty breathing and if you are over 65 years old, it is recommended that you get a flu shot and pneumonia vaccine every year.

5. Pulmonary function test: Pulmonary function test is an accurate way to tell you the status of your respiratory health. It can detect the symptoms of many important lung diseases in the early stages, giving you time to make lifestyle changes.
