What are the symptoms of mid-term lung cancer

Lung cancer has some symptoms in the early stages, but because the symptoms are not obvious, they are easily overlooked. Therefore, we also need to understand the symptoms of mid-stage lung cancer. Some mid-stage symptoms are introduced below.

1. Hoarseness is the most common symptom of mid-stage lung cancer

The recurrent laryngeal nerve that controls the left side of the voice function goes down from the neck to the chest, bypasses the large blood vessels of the heart and goes back up to the larynx, thus controlling the left side of the voice organ. Therefore, if the tumor invades the left side of the mediastinum and compresses the recurrent laryngeal nerve, hoarseness will occur, but there will be no sore throat or other symptoms of upper respiratory tract infection.

2. Pain

The chest cavity is a very complex space. Three-quarters of the lung surface is surrounded by the chest wall, which is composed of a thin layer of lining (parietal pleura), fat, muscle, ribs and skin in different proportions. Tumor invasion of any of the above parts will cause pain. Therefore, most patients with lung cancer that have regional intrathoracic spread have symptoms of chest pain. Surrounding the top of the lung, that is, the apex of the lung, forms a special area of ​​the chest wall. The sensory and motor nerve fibers from the neck that control the upper limbs all enter the upper limbs through this area. Therefore, if the tumor invades this area, you will often feel pain and fatigue in the upper limb on the affected side. This is also one of the symptoms of mid-stage lung cancer.

3. Shortness of breath and pleural effusion.

Almost all patients with regionally spread lung cancer experience shortness of breath to varying degrees. Normal tissue fluid produced by the lungs and heart muscle is returned by the lymph nodes in the middle of the chest. If these lymph nodes are blocked by the tumor, this tissue fluid will accumulate in the pericardium to form a pericardial effusion or in the chest cavity to form a pleural effusion. Both of these situations can cause shortness of breath.

4. Edema of face and neck

On the right side of the mediastinum is the superior vena cava, which transports venous blood from the upper limbs and head and neck back to the heart. If the tumor invades the right side of the mediastinum and compresses the superior vena cava, it will initially cause the jugular vein to swell due to poor blood return, and eventually lead to edema of the face and neck, which needs to be diagnosed and treated in a timely manner.

The above are some of the symptoms of mid-stage lung cancer. Do you understand them? If you have any questions about the above, please consult online experts or call the hotline. Keeping abreast of your physical condition is the guarantee of your health. I hope the above content can help you.
