    Colon Cancer: Genetic testing

    Hi all! So far I am assumed to have hereditary colon cancer, so today I am off to see the genetic counselor for genetic testing. Do any of you have any recommendations on questions to ask while I am there? Thanks!!

      It will be the genetic counselor that will ask the question. Genetic testing often involves a questionnaire regarding your medical history as well as that of blood relatives. A blood sample is taken and processing the DNA and isolating specific genetic markers can take weeks or months. Other than if you have some general questions about the testing process there really isn't anything to ask at this point. It would sort of be like asking the lab tech that draws you blood what the results of the tests that haven't been run yet are.

      You might want to ask what specific types of testing they are doing, panels, one specific mutation etc. How long you will have to wait for the results. Cost (some insurance companies many not cover the cost of some testing) What types of results can you get, for example I am waiting for the result of a BreastNext Panel I am told that each gene tested will come back with one of three results -positive -a known mutation and what it is. Negative: At this point in time Gene does not have any known mutations. Variation - Gene has a variation but at this time it is unknown if it is a normal one or a mutation.

      You might want to ask if they can better target your treatment based on any mutations found. I was told some mutations don't respond to certain types of treatment, and some do better with specific meds.

      I recently had my tumor analyzed genetically. The result was negative for Lynch syndrome. That meant my children did not have to worry about it being genetic.

      A sample of my tumor was sent to the lab. I never saw the genetic facility...no blood draw, etc.

      Now that I recall I did have a lengthy discussion with a counselor via the phone to establish whether or not I was a candidate for genetic testing.
      Sorry this response is so fragmented.

      Colon cancer runs in my family. Early detection seems to be the key. I had colonoscopies done 2 times across ten year intervals. The last one was less than ten years and cancer was detected. I had no symptoms.
      I'd ask if there is more than one gene involved in inherited cancer and which gene is most likely to cause cancer. I've heard that we all have a form of cancer even if it is not detected. It is triggered by something.
