What signals do your legs give before lung cancer comes?

Lung cancer is a common malignant tumor of the respiratory system. Its early symptoms are often not obvious, which leads to many cases being diagnosed in the middle or late stages. However, during the development of lung cancer, the legs may send out some signals in advance, reminding you to pay attention to abnormal changes in the body, including leg swelling, leg pain, leg weakness, limited movement, lower extremity vein thrombosis, etc. The details are as follows:

1. Leg swelling: Lung cancer may cause blood circulation in the legs to be impaired, which in turn may lead to blood clots and cause leg swelling. This swelling may be accompanied by prolonged hypoxia and ischemia of the muscles, causing abnormal bulges in the legs and a hard touch.

2. Leg pain: When lung cancer metastasizes to the bones, especially to the bones of the legs, it can cause severe pain. The growth of lung cancer tumors may also compress the blood vessels and nerves leading to the legs, causing pain or tenderness in the legs.

3. Weakness in both legs: In the late stage of lung cancer, neuromyopathy syndrome may lead to myasthenia-like syndrome, which is often manifested as proximal muscle weakness in both legs, affecting daily activities such as going upstairs, taking a bath, squatting and standing up, etc.

4. Limited movement: After the local expansion of lung cancer tumors, it may affect the movement function of the legs, resulting in limited movement and difficulty in walking.

5. Lower limb venous thrombosis: Lung cancer is prone to lower limb venous thrombosis due to long-term bed rest or tumor compression, which further aggravates leg swelling and pain.

The appearance of these signals should cause me to pay great attention and go to the relevant departments of regular hospitals for treatment in time. Through systematic examination and treatment, I can detect lung cancer earlier and take corresponding treatment measures, thereby improving the survival rate and quality of life. At the same time, maintaining a healthy lifestyle and regular physical examinations are also important measures to prevent lung cancer.
