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.
A blow to the kidneys, caused by a kick in the back for instance, can also lead to blood in the urine. Red urine may be a possible sign of cancer along the urinary tract-the growth of fragile blood vessels around the tumour can cause blood to seep into the urine. 'Seeing blood in the urine is associated with cancer in about one in five cases-most commonly bladder cancer,' explains Mr Laniado.
