  • Insulin-producing tumors????? Has Anyone Heard of This?

    We jsut got back from the Oncologist follow-up appointment. Tim's ct scan was fine and so was his blood work except for the blood sugar part. I guess the norm is 65 & Tim's was in the high 50s. The doctor had him repeat the test & woudl not listen to me- when he had his bllod drawn he had not had anything to eat, & today we repeated the test for bllod sugar & he had not eaten, but I grabbed my daughter's juice & made him drink it.

    Here are my questions- the doctor said he has had tons of these tests run & no one has never had a tumor, but he still checks for it. Do I need to worry? Is this restated to his TC (he had stage 1A Seminoma & then did Carboplatin 2x.)

    If he does have this???? Gish I hope he does not, what will happen, will more tests be run?

    Normal glucose

    Normal glucose should be between 60-100. A glucose in the high 50's is fine especially if he had not ate aything. I have never heard of an insulin producing tumor and I am a nurse (this does not mean it does not exisit). Hope this information helps.

      They do exist, they are insulinomas, a tumor of the islet cells of the pancreas:

      Insulinomas are the most common cause of hypoglycemia resulting from endogenous hyperinsulinism. In a large single-center series of 125 patients with neuroendocrine tumors, insulinomas constituted the majority of cases (55%), followed by gastrinomas (36%), VIPomas (vasoactive intestinal polypeptide tumor) (5%), and glucagonomas (3%).

      Detected mass 10-6-06, Radical left I/O 10-10-06, Stage I seminoma, 1.5 cm primary, No LV invasion, No Rete Testis Invasion... Currently on Surveillance.

        I don't know anything about the type of tumor, but my husbands glucose is always 120-150, non fasting, which is high for non fasting and no one ever worries about it.

        Not my husband, not his oncologist.

        And my husband wont' NOT EAT before he gets his blood drawn, go figure.

        I guess they just don't like being told what to do!

        Hope you get some answers and all turns out well.

            It's great to have reassurance that all is well!
            right inguinal orchiectomy 6/5/2003 > nonseminoma, stage I > surveillance > L-RPLND 6/24/2005 for recurrence, suspected teratoma but found seminoma, stage II > chylous ascites until 9/2005 > surveillance and "all clear" since
