The silent killer: Recognize the early signs of lung disease
Lung cancer is one of the deadliest cancers in the world. It is often diagnosed in the late stages when treatment is more difficult. Therefore, it is essential to recognize the early and late symptoms of lung cancer, so that it can be detected and treated early.
Early symptoms of lung cancer
Unfortunately, the early symptoms of lung cancer are often nonspecific and can be confused with those of other, less serious diseases. However, there are some symptoms to watch out for:
- Persistent cough: The cough may be dry or accompanied by phlegm.
- Hoarseness: It may be the result of the tumor spreading to the vocal cords.
- Chest pain: The pain may be mild or severe and may worsen when coughing or breathing deeply.
- Shortness of breath: It may gradually worsen as the disease progresses.
- Unexplained weight loss: Significant weight loss without any change in diet or exercise.
- Fatigue and exhaustion: feeling of constant fatigue and general weakness in the body.
- Loss of appetite: loss of desire to eat.
Important: Not all of these symptoms may appear in everyone with lung cancer, and other symptoms not listed here may appear.
Late symptoms of lung cancer
As the disease progresses, symptoms worsen and new symptoms appear, such as:
- Coughing up blood: The appearance of blood in the sputum is a serious warning sign.
- Swelling of the face and neck: may occur as a result of the tumor pressing on blood vessels or lymph nodes.
- Pain in the bones: Cancer may spread to the bones, causing severe pain.
- Persistent headache: may occur as a result of the spread of cancer to the brain.
- Yellowing of the skin and eyes: may indicate liver problems.
Why is early diagnosis important?
Early diagnosis of lung cancer significantly increases the chances of recovery. Treatment in the early stages is more effective and less invasive.
Causes of lung cancer
- Smoking: Smoking is the leading cause of lung cancer.
- Exposure to carcinogens: Exposure to certain chemicals in the workplace, such as asbestos and radon, can increase the risk of lung cancer.
- Family history: People with a family history of lung cancer are more likely to develop it.
- Aging: The risk of lung cancer increases with age.
How is lung cancer diagnosed?
Lung cancer is usually diagnosed by:
- Chest X-ray: This is the first examination usually performed.
- Computerized tomography (CT scan): provides more detailed images of the lungs.
- Endoscopy: A thin tube with a small camera is inserted into the lungs to take a tissue sample.
- Biopsy examination: A tissue sample is examined under a microscope to confirm the presence of cancer cells.
When should I see a doctor?
If you experience any of the above symptoms, especially if they persist or worsen, you should see a doctor immediately.
Conclusion
Lung cancer is a serious disease, but it can be cured if detected at an early stage. Therefore, everyone should pay attention to any changes that occur in their health, and turn to the doctor immediately when they feel any abnormal symptoms.
