Can happen: It can happen when the cancer-usually located on the central area- erroded/invaded major blood vessel-massive hemoptysis can happen. The bleeding can be even more if patient is also getting an anti vegf inhibitor- like avastin (bevacizumab).

Lung CA and Bleeding: I have to assume this is prior to diagnosis and treatment?Lung cancer is much like an open sore that won't heal.At times when you cough the scab loosens and the area bleeds resulting in hemoptysis.During treatment bleeding can be from tissues that are raw, and after treatment it can be related to spider veins that are more fragile. These can crack and bleed.

Can be: A symptom of lung cancer can be hemoptysis, or coughing up blood. This can be the result of a tumor in the bronchus or airway, causing irritation.

Ulceration: Blood tinges sputum is usually due to ulceration of the cancer affecting the airways. Lung cancer can invade large blood vessels and cause fatal hemoptysis.
