Genetic testing for breast cancer?

[satya]

My mum's oncologist told her that usually you need 3 female relatives (grandma, aunts, cousins, sisters) to look into genetic factors for breast cancer.

In my family we have 3 who've had it - my mum, my cousin & my aunt (deceased) but they don't consider it (yet) to be genetic as my mum's is imflammatory breast cancer which is completely different & not believed to be genetic.

I would think that you will be charged for the genetic testing. If you are in a high risk family (my family is classed as high risk, just not high risk for the genetic kind) you can get referred to a bulk billing clinic for ultrasounds & mammograms but as far as I know you will still pay for genetic testing.

I had genetic tests for miscarriages a while ago & I was out of pocket around several hundred dollars & no-one warned me of the cost at the time, just got the bill in the mail & medicare covered hardly anything.... so check very thoroughly on the costs if you do go ahead with it so you don't get any nasty surprises. My mother also was tested for a different genetic thing not long ago & was sent a bill for it despite being an aged pensioner & again medicare covered just a tiny portion of it. Lots of things aren't covered by medicare these days.... my mum has even had to pay for some of her chemo & scans.

Thanks Satya. I was pretty sure there'd be some kind of cost involved. Glad you warned me

Well all of Grandma's siblings have had some form of cancer. 1 had a brain tumour, 1 had abdominal cancer of some kind & the other we aren't too sure about. He has passed & mum is sure it was cancer of some kind, but not sure what.

So does that work at all? Would you be genetically inclined to get any type of cancer? Or was that just a fluke that all 4 have had cancer of some kind??

There are some genes that cause more than one type of cancer, but you would have to get the medical reports from the relatives to see the specific types of cancer, and see a geneticist or genetic counsellor for further info.

In Victoria, all reports are collected through the Cancer Council of Victoria so it is an easier process to get access to the reports. In NSW, I believe that you have to get access to each person's medical information individually from their doctor, which requires permission from the person or next of kin. (The Genetic Clinic can help with this if it sounds like the cancers may be genetic)

In relation to the breast cancer genes, the criteria for 'potentially high risk' and follow up with a genetics clinic for those women without breast or ovarian cancer are:

Two primary or secondary relatives on one side of the family with breast or ovarian cancers PLUS one or more of these features in same side of family
*another relative with breast or ovarian cancer
*breast cancer diagnosed before age 40
*bilateral breast cancer
*breast and ovarian cancer in the same woman
*Ashkenazi Jewish ancestry
*breast cancer in a male relative

OR

One primary or secondary relative diagnosed with breast cancer at age 45 or younger PLUS another primary or secondary relative on the same side of the family with sarcoma (bone/soft tissue) at age 45 or younger.

Genetic testing through a familial cancer centre does not cost the 'patient' anything. Only those families that meet the criteria, and where the chance of finding a gene mutation is high will have genetic testing.

Other genetic testing can have out of pocket expenses, but you should be informed of this prior to the testing being performed.

Thankyou

My mum's mum had breast cancer and my mum died of an ovarian cancer which was actually a type of breast cancer. Because of this I was allowed to be referred to westmead hospital to get this testing done and have counselling, because it is free its a long wait for an appointment- sadly for me my grandma died the week of the appt- before it and the genetic testing cannot be done without the blood sample of a relative who has survived the disease so although I was offered counselling there was no way to do the testing.
They were only interested in me for testing because I had direct female relatives with the disease- its more likely to be passed from mother to daughter, also grandma'smum had died in the 40s of cancer of the uterus which could easily have been the same sort of cancer so being in the direct line of all these cancers was pretty scary for me and still is.
I would be much less concerned BJ cause its your dad's side but I understand your fears.

Thanks Mrsmac. It never really occured to me TBH. Its mum's idea. She would rather us be prepared for what could be ahead IYKWIM. Especially since my sis already has similar problems.
I'm sorry your Grandma passed when she did

[mrsmac]

No worries BJ, yes it was sad but she was 92, my mum sadly had already died at just 61.
