Lung cancer is one of the most common and most dangerous types of cancer in humans, and many cases of cancer-related deaths are caused by this type of cancer, because the diagnosis of this disease in most patients is often at an advanced stage. Lung cancer is often fatal, especially if it is diagnosed at a later stage. The disease disrupts lung function, leading to the death of the patient, but there is still a cure. Therefore, we see that doctors always advise people to conduct regular regular checks until any malignant disease is detected early, eliminated before the condition worsens and worsens, and the recovery rate decreases.
Lung cancer is shared with other types of cancers in terms of the general nature of the disease and its causes. Almost all cancers share a common malignancy that is caused by the division and spread of a host of aggressive cells in some areas of the human body. Spreading to the penetration and gradual destruction of healthy cells and tissues in the human body.
Lung cancer may affect the right lung alone without the left, and may strike the left without the right, and may infect them together. Doctors all over the world are unanimous that the primary culprit and the main cause of lung cancer is smoking. Smoking is the cause of more than 80% of lung cancer cases diagnosed annually. Smoking is also the primary responsibility for many other cancers.
Lung cancer is associated with other cancers in many of the symptoms and signs that appear on the patient, including:
- Fatigue and tiredness.
- High temperature.
- Anorexia.
- Weight loss.
Common symptoms, which are most often related to lung cancer, are distinguished from many other types:
- Chronic cough. This cough is usually accompanied by a blood-soaked mug.
- Shortness of breath.
- Chest pain.
The symptoms mentioned above often appear on the patient at an advanced stage of the disease, the disease in its initial stages is silent, and does not feel the patient in these stages anything, and this is why the diagnosis of the disease comes late in many cases. Lung cancer is diagnosed in many ways. The most common are X-rays, CT scans that are more precise and detailed than X-rays, ultrasound, and biopsy of biopsies by biopsy.
