My Husband Just Had An Ultra Sound For An Anyurism

My husband just had an ultra sound for an anyurism check and was told that there are some markings on his liver and that he should have a CT scan to check things out. We are scheduled to leave for a 3 month holiday which does not give us time to have the scan. He is 75 years old and does not have any symptoms of liver disease. Should we cancel our plans or arrange to have the scan done in April when we return home. Thankyou for any suggestions.
