@hels Welcome to Mayo Clinic Connect! As you read through the posts here, you see a wide range of experiences. Like you experienced, MGUS is often diagnosed while our doctors are checking for something else. The very biggest percentage of time, people go many years without any progression of the condition. Most of us have quarterly labwork done to watch the numbers.

Have you gotten travel insurance in the past?Honestly, it's not something I had ever considered, but then again I am not much of a traveler.
