How do I know if I have lung cancer? If you have these 4 abnormalities in your body, it may be lung cancer

When I was watching the news, I found a case of lung cancer. An old man went to the hospital for a detailed examination because of an irritating cough and was diagnosed with lung cancer. Because of his old age, the doctor recommended chemotherapy, but after two courses of treatment, the old man decided to give up because he couldn't bear the pain of chemotherapy. It was just 5 months from diagnosis to death.

For all cancers, early detection is crucial. The earlier the detection, the better the treatment effect. Once some minor symptoms are ignored, the disease will be in the middle or late stages by the time it is discovered. Therefore, in order to stay away from death, it is necessary to detect the early symptoms of lung cancer in time. No matter what kind of cancer it is, there will be some clues in the early stage, and you will find clues as long as you pay close attention.

What are the early symptoms of lung cancer?

1. Obstructive pneumonia

Lung cancer is often complicated by obstructive pneumonia. Once this type of pneumonia occurs, the cure rate is relatively low and it is easy to recur. When patients develop obstructive pneumonia, they will also have varying degrees of fever.

2. Chest pain

Diseases such as lung cancer are prone to local symptoms or distant metastasis after their onset, which can cause chest pain. When lung cancer metastasizes to a series of parts such as the chest wall, pleura, and thoracic vertebrae, varying degrees of chest pain will occur.

3. Difficulty breathing

Most lung cancer patients will experience difficulty breathing, which is mainly caused by lung cancer blocking the patient's trachea. It may also be caused by the gradual increase in the size of the tumor and squeezing the lungs, which can also be understood as difficulty breathing. If the disease has developed to the middle and late stages, it can be slightly relieved by oxygen inhalation. However, if lesions such as lung cancer threaten the large airways and cause blockage, then it can only be treated through surgery.

4. Irritating cough

Lung cancer often causes irritating coughs, which is a typical early symptom. When coughing symptoms occur, most people mistakenly think that it is caused by bronchitis, so such symptoms are easily ignored, which eventually causes the disease to deteriorate rapidly.

In addition to the above early signs of lung cancer, patients may also cough up sputum with blood in it. This is mainly because lung cancer is very densely distributed on the surface, and when an irritating cough occurs, it is easy to cause blood vessels to rupture, which in turn causes blood in the sputum.
