【Case Studies】

Mr. Lin from Jinan, Shandong Province, 35 years old this year. He is a factory worker. He has been addicted to smoking for decades. He can be regarded as a very typical old smoker. He practiced as early as he was young.

But in May of last year, Mr. Lin felt back pain in his body, accompanied by inability to walk, numbness in legs and feet, varicose veins, and sometimes even hoarseness.

Why is lung cancer diagnosed at an advanced stage?

From the case of Mr. Lin above, we can see that it does not mean that lung cancer will inevitably have various discomforts in the advanced stage, but that most patients do not have many obvious symptoms when they are diagnosed, and they look no different from normal people. ,Why it is like this?

As the most important respiratory organ of the human body, the lungs are also the main location for gas exchange between the inside and the outside world. Although powerful, the lungs are also very fragile and delicate.

Affected by unhealthy eating habits and environmental pollution, regular smoking will lead to a decline in lung function and induce lung lesions. When there is a small lesion, the lungs do not feel it, and they are even less aware of it.

However, with the passage of time and the aggravation of the disease, various metastases will appear. The most common metastases are the brain, bones, liver, lymph nodes and pleura.

All cancers are the same, including lung cancer. Early treatment can only be achieved when symptoms are detected at an early stage. According to relevant data, after standardized treatment, the curability of in situ lung cancer patients may reach more than 90%. Lung cancer patients account for about 15%.

Therefore, the most unacceptable thing is that when most patients discover lung cancer, they are diagnosed at an advanced stage. The most fundamental cause is lung cancer, which itself is a type of cancer that is difficult to detect at an early stage. Discomfort, by the time there is a serious problem in the body, it may have developed to an advanced stage.

Therefore, I also hope that everyone can develop the good habit of regular physical examination in their daily life, so that they can understand the health status of the body in time, discover the potential causes in the body in time, and achieve early detection, early prevention and early treatment.

Doctor's reminder: Legs may have tips, just didn't pay attention

[Unusual swelling of the legs]

In daily life, if it is not because of heavy physical labor or sprain, suddenly found abnormal swelling of the leg. And it lasted for a very long time, which requires everyone to be highly vigilant.

This is most likely caused by the appearance of lung tumors. When you have lung cancer, it will affect the blood circulation, which will block the blood circulation in the lower extremities, and cause blood clots to cause swelling in the legs. There will also be abnormally raised lumps. It feels extremely hard.

[Obvious pain in the legs]

If you suddenly feel abnormal pain on one side of your leg in your life, it may also be a sign of lung cancer.

During the continuous growth of cancer cells in the lungs, it will cause compression to the surrounding nerve tissue, so it will also cause compression to the legs, and the legs will frequently experience pain. During the stage of bone metastasis, the pain will be significantly aggravated, and the patient will also bear enormous psychological and physical pressure.
