When analyzing the characteristics of blood in sputum that may be related to lung cancer, it is usually necessary to judge based on the color of the sputum, symptoms, etc. It is also recommended to go to the hospital for diagnosis to determine what type of cancer it is.

Blood in sputum caused by lung cancer usually appears bright red or dark red. This is because lung cancer destroys lung tissue, causing bleeding, which makes the sputum appear bloody. Sometimes there may be brown or black blood clots, which may indicate that the bleeding is deep. In addition to blood in sputum, lung cancer patients often have symptoms such as coughing, difficulty breathing, chest pain, and weight loss. The presence of these symptoms can further indicate that the blood in sputum may be caused by lung cancer. Smoking is the main risk factor for lung cancer, and long-term smoking increases the risk of lung cancer.
