Hi, I am an American Board Certified Neurologist with experience in treating all neurological and other medical conditions and I am very glad to help you with your health concerns.
The findings in the liver does not automatically mean something serious.
There are many benign conditions too that can cause such lesions in the liver.
This needs to be investigated further to find out the precise cause for these multiple lesions.
If you are worried about radiation exposure then an MRI can be arranged instead of CAT scan
Your blood tests all being normal risk of bleeding or rupture is very low.
Pain can be treated with relatively safer pain meds like Tylenol
Chances or cancer can only be told after completing all the investigations, but please see that the type of lesions you are having in the liver can very well be benign non-cancerous lesions too, so please not to panic now. The lesions are small, the blood tests are all normal, all these increases the chances that this could be some non-cancerous condition.
Please let me know if you have any further questions; and if you feel you have received the answer to your question please rate me so that I can receive credit for the time and effort put by me in answering your question.
