genetic testing?

I've been asked by one of my siblings if I'd had any genetic testing as a part of the whole diagnosis/treatment biz.  We have another sibling who has survived colon cancer.  My sister's gynecologist is interested in testing her because of the two of us having had colon and anal cancer.  I know that I reported my brother's cancer and my mother's melanoma as a part of family history when I was meeting with doctors but none of them suggested genetic testing.

My sister's doctor is interested in testing for Lynch Gene(HNPCC) and BrCa1&2.  I know that Lynch syndrome is associated with colon cancer and BrCa1 & 2 are associated with breast and ovarian cancers.  And that's about all I know

So I'm curious if anyone here has been tested and if anyone knows if squamous cell anal cancer is linked to Lynch syndrome.

I told my sis I'd check in with my oncologist about this but before I do I thought I'd gather any info I can from you all first

Thanks

I have not had such testing and know of no connection between anal cancer and Lynch syndrome, but I have not researched that.

I had this for my ataxia. At that time the geneticist decided she wanted to do for cancer also.   I wouldhave been 50 in a few months when they found the cancer in sept 2010.  They decided not to do the test because I was not 50 yet.  ItEven though the genetic testing was done when I was 51 .  It makes little sense to me.  I have had two prior skin cancers invasive and non.  I also had cervical dysplasia stage 5 in my 20's.  I think these are the things that prompted them to want to test for further cancer possibilities.  Sometimes I wonder if they did it and are just not telling me.  I am self employed and never plan on changing my ins carrier, so I was comfortable with having the tests performed.

I was never asked or have asked about genetic testing regarding my anal cancer. My mom died of ovarion cancer, and grandma of pelvic cancer of unknown origin??, so when I was diagnosed with breast cancer did have genetic tests done to see if I carry the mutated Brac gene, since there is a relationship between breast and ovarion cancer. I have five children and may have had an effect on early screening for them. I did/do not carry the mutated gene, so am more concerned now about environmental factors. I had to meet with a genetic counselor first to see if I had enough of a reason for insurance to cover it...they did.

Sorry, i don't know much about Lynch syndrome.

Let us know what you find out.

Strange.  When I opened the mailbox yesterday there was invitation from my provider to participate in a gene study on cancer and othernautoimmune diseases.  I have reservations but want to participate.

My oncologist told me that the Lynch gene (HNPCC) is associated with colon cancer and that anal cancer is not related to Lynch and is more related to HPV.  His office is going to check to see if my insurance would cover testing for this gene.  I'll get tested if it's covered.  If it's not covered I'll leave it to my sister to get tested.  So far in our family only my brother has had colon cancer and was 58 when diagnosed (one of the red flags for Lynch syndrome is having colon cancer before the age of 50)
