The most common symptoms of lung cancer patients include coughing, followed by coughing up blood, difficulty breathing, and chest pain. When the tumor grows in larger bronchi, it often causes an irritable cough, which can easily be mistaken for a cold. As the tumor continues to grow and affects the drainage of the bronchi, secondary lung infections can occur, possibly producing purulent sputum and an increased amount of coughed-up sputum. At this time, coughing becomes quite severe. Another symptom that may appear is blood in the sputum, which could be blood-streaked sputum, or sporadic, small amounts of coughed-up blood.

How to detect early symptoms of lung cancer?

So, the early symptoms of lung cancer often include a cough, hemoptysis, difficulty breathing, and chest pain. However, these symptoms, particularly the irritating cough, typically appear after the tumor has grown in the larger bronchi; this is often mistaken for a cough following a cold, leading to misdiagnosis or delayed treatment. Therefore, if this type of irritating cough occurs, it is essential to seek medical attention promptly and to undergo chest X-ray or CT scan. Second, as the tumor continues to grow and affects the drainage of the bronchus, secondary lung infections may occur, often characterized by coughing up pus-like sputum, and an increase in the amount of sputum, which should also be noted. Third, a very common symptom is the presence of blood in the sputum, or streaks of blood, or intermittent minor hemoptysis, which must be taken seriously.

How to stop coughing and wheezing in the late stage of lung cancer

Lung cancer is a relatively common type of malignant lung tumor clinically. Due to the different specific types of lung cancer in different populations, the symptoms experienced by patients also vary. In the early stages of lung cancer, symptoms are generally characterized by irritative dry cough, hemoptysis, breathlessness, and chest tightness. As the tumor grows and metastasizes, patients in the later stages may experience varying degrees of coughing, wheezing, and expectoration. For such patients, the first step is to provide appropriate anti-infection treatment and oral administration of antispasmodic drugs. Inhalation of medications that relieve bronchospasm can also be chosen, both of which can achieve a certain effect in relieving cough and easing breathing.

Is coughing severe in the early stages of lung cancer?

Patients with lung cancer in the early stages may experience severe coughing, mild coughing, or no coughing symptoms at all. Many early-stage lung cancer patients have lesions located near the periphery of the lungs that do not involve the airways or other significant structures, typically resulting in no clinical symptoms. By the time clinical symptoms appear, the patient may already be in the middle or late stages of lung cancer. Additionally, it is important to note that some patients with early-stage lung cancer may also experience coughing, which can range from severe to mild, and may include coughing up blood. Such symptoms are often seen in early-stage central lung cancer, which frequently presents with cough and blood in the sputum. Therefore, older patients with a long history of smoking who suddenly develop a cough or start coughing up blood should be highly vigilant and likely need to undergo chest CT scans, bronchoscopy, and other related examinations for evaluation.

Is lung cancer contagious?

The occurrence of lung cancer is associated with smoking, air pollution, and working in environments such as coal mining. However, lung cancer is not contagious. Therefore, in clinical settings, family members of patients often ask doctors whether lung cancer can be transmitted through the respiratory tract. It can be assured that lung cancer is not contagious; only communicable diseases like tuberculosis can be spread this way.

How is lung cancer caused?

The specific causes of lung cancer are not completely clear, but there are some high-risk factors. Research has shown that lung cancer is influenced by a combination of genetic defects and internal and external environmental carcinogens. It is undeniable that long-term heavy smoking is the most important carcinogenic factor for lung cancer, with the amount and duration of smoking being positively correlated with the incidence of lung cancer. Secondly, environmental factors, such as working with asbestos or in mining areas, are also very relevant to the incidence of lung cancer. Thirdly, irregular eating habits, rest, alcohol consumption, indoor combustion, coal smoke, fumes from kitchen cooking, and carcinogenic substances released from indoor decorations and materials are also related. Fourthly, the body's internal immune status, metabolic abnormalities, genetic factors, and chronic lung infections also have a significant impact.
