Introduction
Lung cancer patients may experience itching because cancer cells release various vasoactive hormones that irritate the skin. When lung cancer metastasizes to the liver and forms metastatic lesions, it can cause abnormal bilirubin metabolism, leading to symptoms such as dark yellow or yellowish skin. Due to severe lung damage, insufficient oxygen is supplied to the body, impairing blood oxygen exchange and easily resulting in symptoms like cyanosis of the skin.
Lung cancer has a very complex etiology, and there is currently no definitive conclusion. However, patients with lung cancer may experience skin symptoms such as itching, yellowing, or cyanosis. The specific details are as follows:
1. Itching
Cancer cells can release various vasoactive hormones, such as bradykinin, serotonin, and catecholamines, which may irritate the skin and easily lead to itching.
2. Yellowing
When lung cancer metastasizes to the liver, metastatic lesions form. If these lesions grow large enough to impair normal liver function, bilirubin metabolism becomes abnormal, resulting in symptoms such as dark yellow or yellowish skin.
3. Cyanosis
Due to severe lung damage, the body cannot receive sufficient oxygen, impairing blood oxygen exchange. This often leads to purplish discoloration of the skin, known as cyanosis.
In addition, symptoms such as petechiae (small bleeding spots) and bruises (ecchymoses) may also occur. Patients experiencing these symptoms are advised to seek timely medical evaluation and appropriate treatment.
