I had rectal cancer that was removed 2 years ago, a year ago a CT scan showed two spots in the liver, doctors recommended MRI to the liver to confirm if it was cancer, first MRI didn t confirm, but second MRI performed three moths after did show a third spot and the bigger spot (1.8 cm) growing 3 mlimiters compare to previous MRI. Since I had bowel cancer previously doctors are almost certain this is a metastasis to the liver, but oncologist is recommending a liver biopsy. I don t want to do this as I understand there is a risk of cancer seeding and I am suggesting to get surgery without having the biopsy. Can I have your opinion please, is biopsy risky in this case?
