Increased pulmonary markings are clinically associated with many inducing factors, but they are not directly related to liver cancer. It's important to understand that liver cancer involves the presence of cancer cells in the liver, while increased pulmonary markings are radiographic signs observed during lung imaging examinations. Clinically, there are many factors that can lead to increased pulmonary markings, but liver cancer does not cause this condition. Typically, increased pulmonary markings may be due to excessive obesity, long-term smoking, or the presence of inflammatory lesions in the lungs, all of which can cause varying degrees of increased pulmonary markings.
