Methods for treating a tumor, a treatment catheter for treating a tumor and a kit for treating a tumor are described. In one aspect of the invention, a method for treating a tumor includes placing a radioactive material at a first predetermined site within an intact internal thoracic vessel for a time period sufficient to provide a therapeutically effective amount of radiation. Placing a radioactive material at a first predetermined site may include positioning a first catheter in the lumen of an intact internal thoracic vessel and placing a radiation source at a predetermined site within the lumen of the first catheter. The methods are advantageous for treating breast cancer, including breast cancer that has spread to the parasternal lymph nodes.
