My .mother was diagnosed with colon cancer with mets to the liver. (5 lesions) The Sirt spheres were done about 2 years ago via an angiogram
It had some complications because my mother was 85 atthe time, but it slowed down the liver cancer remarkably - the one consideration was the status of her being radioactive apparently this is for about 7 days - she was released from hospital after about 48 hours for us to cope with.
The complication she had was related to her heart, but she survived this.
It was an uncomforatble procedure but was found tocalcify the lesions, and restrict their growth.
A worthwhile procedure - there are things that relate to the quality of the person doing the insertion - that they go to the site that is intended etc, but that covered - go for it!
