What are the signs of lung cancer? Understand these body’s help messages

Lung cancer, as a common malignant tumor, early detection and treatment is of great significance to improving patient survival rate. However, the early symptoms of lung cancer are not obvious and can easily be ignored. This article will reveal the early signs of lung cancer from a professional perspective and help you identify the hidden signals of lung cancer and the distress messages sent by the body.

1. Revealing the early signs of lung cancer

1. Persistent cough : Cough is one of the most common early symptoms of lung cancer. When tumors appear in the lungs, they can irritate the respiratory tract and cause persistent coughing. This cough is often difficult to relieve and may be accompanied by bloody phlegm.

2. Chest pain : Patients with lung cancer may experience dull or dull pain in the chest, especially when taking a deep breath, coughing, or changing posture. Chest pain may be related to tumor invasion of the pleura or chest wall.

3. Dyspnea : As the tumor grows, it may compress or block the airway, causing difficulty in breathing. People may feel short of breath, wheeze, or be unable to take deep breaths.

2. Identify hidden signs of lung cancer

1. Weight loss : Continuous weight loss without obvious reasons may be a hidden signal of lung cancer. Tumors consume a lot of energy, causing patients to lose appetite, malnutrition, and weight loss.

2. Hoarseness : When lung cancer invades the recurrent laryngeal nerve, it may cause hoarseness. Symptoms often persist and are not easily relieved.

3. Systemic symptoms : Lung cancer patients may also experience systemic symptoms, such as fatigue, fever, night sweats, etc. These symptoms may be related to metabolites produced by the tumor or to immune responses.

3. Lung cancer warning: the body’s message for help

1. Blood in sputum : Blood in sputum is an important early warning sign of lung cancer. When tumors invade blood vessels in the lungs, they may cause blood streaks or blood clots in the sputum. Once you find blood in your sputum, you should seek medical examination immediately.

2. Swelling of lymph nodes : Lung cancer may metastasize to lymph nodes through lymphatic channels, causing lymph nodes to swell. Patients may feel a painless lump in areas such as the neck, armpit, or groin.

3. Abnormal lung imaging : During regular physical examinations, lung imaging examinations (such as X-ray, CT, etc.) may reveal pulmonary nodules or masses. These abnormal images may be early manifestations of lung cancer and require further examination for diagnosis.

Solutions and daily precautions

For the prevention and early detection of lung cancer, the following suggestions are crucial:

* Quit smoking : Smoking is the main risk factor for lung cancer, and quitting smoking is the most effective way to prevent lung cancer.

* Avoid occupational exposure : Reduce exposure to asbestos, arsenic, chromium and other carcinogens to reduce occupational exposure risks.

* Regular physical examination : It is recommended that people over 40 years old have a lung imaging examination once a year to detect lung abnormalities in time.

* Healthy diet : Eat more foods rich in vitamins A, C, E and beta-carotene, such as carrots, spinach, citrus fruits, etc., to enhance lung health.

* Exercise : Maintain moderate exercise to enhance body immunity and reduce the risk of disease.

By understanding the early signs and hidden signs of lung cancer, we can better protect against this disease. Please cherish every distress message sent by your body and seek medical examination in time to protect your health.
