When lung cancer comes, your legs may be the first to sound the alarm →

Lung cancer is a very common malignant tumor worldwide, and its morbidity and mortality rates remain high. What is even more worrying is that many patients are already in the middle or late stages when they are diagnosed, missing the best time for treatment. But today, I want to tell you that lung cancer is not without traces. Sometimes, our legs will give us some important "help signals."

Lung cancer is not far away from us

First, let's look at a true story. Aunt Liu, 58 years old, has been troubled by chronic bronchitis. Three months ago, she began to have an abnormal cough, and even coughed up blood in her sputum. After going to the hospital for examination, she was diagnosed with lung cancer, which had already developed to the middle and late stages. Aunt Liu was confused. She never smoked, so why did she get lung cancer?

In fact, the causes of lung cancer are very complex. Although smoking is the main risk factor, it is not the only one. Long-term exposure to secondhand smoke, staying up late, working overtime, and decreased immunity, as well as environmental, dietary, and genetic factors can all lead to the occurrence of lung cancer.

The legs’ distress signal

So, how can we detect the signs of lung cancer in the early stages? Here are three abnormal signs of the legs. If you find yourself with these conditions, it is recommended to go to the hospital for examination as soon as possible.

1. Leg pain

If you suddenly find yourself experiencing frequent calf pain, especially if the pain is not caused by obvious trauma or fatigue , you should be alert.

Lung cancer patients may produce substances in their bodies that promote blood coagulation. Once a blood clot is formed, it can lead to local blood circulation obstruction, thereby causing pain.

2. Skin color changes

If the lungs are diseased and the gas exchange process is affected, insufficient blood supply to the lower limbs will cause the skin to appear bluish purple (medically known as cyanosis). Therefore, once you notice that the skin color on your legs has become abnormal, it is best to seek medical attention in time.

3. Unknown lumps appear

Normally, the legs are smooth and free of lumps. However, if you find small lumps on your legs that are hard, difficult to move, and painful , you should highly suspect that they are caused by tumor metastasis.

In addition to the symptoms mentioned above, long-term coughing, bloody sputum, or chest discomfort are also common warning signs of lung cancer. When encountering these situations, do not take it lightly and seek help from a professional doctor for diagnosis in a timely manner.

Early diagnosis and treatment can improve survival rate

The time it takes for lung cancer to develop from early stage to late stage varies from person to person, but early detection and treatment are the key to improving patient survival rate.

Therefore, for the following high-risk groups, such as smokers over 55 years old, people with a family history of lung cancer, people who are exposed to oil fumes or secondhand smoke for a long time, people with a history of occupational exposure, and people who have suffered from chronic lung diseases , it is recommended to undergo a low-dose spiral CT examination at least once a year.

Stay away from lung cancer, do these 4 things

Stay away from tobacco : Smoking is the main risk factor for lung cancer. Quitting smoking and staying away from secondhand smoke are the first step in preventing lung cancer.

Reduce the inhalation of oil fumes : Use a range hood when cooking and open windows for ventilation to reduce the inhalation of oil fumes.

Pay attention to the home environment : reduce indoor pollution sources such as formaldehyde, benzene compounds and other harmful substances.

Strengthen exercise : enhance the body's immunity and reduce the risk of disease.
