With hemangiosarcoma, the pericardium fills up with blood due to rupture of the tumor. When the tumor occurs in the skin, a mass or lump can usually be felt in or under the skin. The mass may become ulcerated and bleed. When the tumor occurs in a bone, it can cause pain and discomfort.
Coughing up blood (hemoptysis) occurs in a significant number of people who have lung cancer. Any amount of coughed-up blood should be evaluated by a health care provider. Pain in the chest area is a symptom in about one fourth of people with lung cancer. The pain is dull, aching, and persistent. Shortness of breath usually results from a blockage in part of the lung, collection of fluid around the lung (pleural effusion), or the spread of tumor through the lungs.
