DCIS and endometriosis- HELP!!

Hi everyone,

totally new to this amazing network and this whole new world of cancer & DCIS!

I am looking for advice to to hear from ANYONE who may have been through something similar to what I am going through.

two months ago I found a lump in my right breast and the GP sent me off to the experts. Biopsy’s, ultrasounds, MRIs, mammograms later it’s DCIS. I am run through the options and go into for a wide local. 
During this surgery they find a 0.8m tumor and remove and take wider margins. However they do not come back clear, so the following week I go back in for some more “housekeeping” and wider margins. 

I was told yesterday that those margins are clear, hooray! 

The direction now is that they want to do 5 weeks of radiation and put me on Tamoxifen for 5-10 years. HOWEVER, I have endometriosis and have been told tamoxifen will heighten my endometriosis. Along with the standard early menopause (should say I am 39 years old with one kid, happy with one child, based in Newcastle NSW). 

As this has already been such a whirlwind, I am trying to find resources or people who have had to go into early menopause - did you get endo side effects? Or if you already had endo, did you opt to have your ovaries etc removed to stop any side effects/pain? 
Or did you opt for a mastectomy instead? Soooo many questions! 

I am discussing with all doctors and specialists but haven’t ever spoken to another person in my position. Please PM me or comment if you want to share your experience 

thanks for listening 😊
  • Hi @Newymum

    Have you read up on Hormone therapy - link to BCNA website

    Hormone therapy and breast cancer (bcna.org.au)

    I had bleeding issues when I started on Tamoxifen and ended up under a  Gynaecology Oncologist.  

    My Medical Oncologist put me on Tamoxifen and Zoladex - Zoladex injection, total of 24 to shut down ovaries.  My Zoladex was able to be administered by my local GP.

    It's a little daunting but certainly doable

    Best wishes as you read up and get a better understanding of your situation
  • No problem at all darl @Newymum.
    Tbh, in your position, I’d ask to be put on an Aromatase Inhibitor, such as Letrozole or Arimidex. That will put you in menopause, well the Zoladex that you’ll take with it will, and that’s more effective at preventing recurrence. You can also avoid more surgery that way, and I think your uterus etc will have a break. 
  • Sounds like May have had endo @FLClover ! And your poor friend! Have have had a few of those surgeries over time and some are worse than others as they always find more. 

    What people have told me about tamoxifen isn’t great, so hopefully there can be another way. Going back to the onocolgist today and asking for a few options to take to the gynecologist 

    It’s great you got to avoid chemo. I was lucky in that respect too. 

    Thanks for your reply 
  • Thanks for commenting @MicheleR 😊

    basically a hysterectomy would massively help my endo, and I was looking at that before I found the lump. But the gyno wanted to leave the ovaries in, but now - who knows. 

    The BC surgeon has mentioned several times that tamoxifen will force me into menopause. 

    I think they want radiation and the tamoxifen as they feel it’s a less brutal option for me as it’s DCIS and not invasive cancer, however I have a family history of BC and seeing they found it early they believe that taking tamoxifen longer term (5-10yrs) will stop anything in the future. But they all have said I will be back in 10 years more than likely with something else! 

    If I didn’t have the 20+ years of living with endometriosis I wouldn’t be questioning it. But the thought of the endo becoming worse while having other side effects is daunting. 

    Back off to the specialist I go!
  • Hi,

    Im not as young as you. 49. I wasnt in menopause though i was kindof praying for it due to 2 migraines a month and heavyish periods. No endo. By all accounts /family history i wouldnt have gone through menopause till i was 55.

    Im now in chemical menopause from chemo and maintained by monthly injection. I guess i could opt for my ovaries out although i havent been offered it and dont want it at the present time. I had a large hormone positive tumour so im on an AI called aromisin to remove the remaining oestrogen from my body. You can only have these if menopausal. Im not sure what the difference between tamoxifin and ais is. I think i read somewhere that tamoxifin increases bone density which is opposite of ais.  Is it because they dont want you to be in menopause due to your age and stage of your breast cancer? Is it less brutal? Oestrogen is something that protects your joints and ligaments.  Dcis i believe is noninvasive so early detected which is great.  If you dont have a cycle does it stop endo? 

    Sorry more questions than answers. 

    Maybe discuss with your team. Removing your ovaries might give you more options but there are side effects youd need to consider. 

    Great to hear surgery went well.

  • Hello 🙂. Sorry to see you here, in the bc forum. A lovely place nevertheless cos of all the ladies 😊.
    I was diagnosed last year, also 39, and also with one child. I had stage one multifocal and simultaneous bilateral, so I had a double mastectomy with the expanders inserted for further reconstruction. I did 5 weeks of radiation and skipped chemo. Cos of that, my oncologist put me on the strongest hormone suppresser, Letrozole, which is an aromatase inhibitor. To take that, you have to be post menopausal, and I wasn’t. So I also have to take monthly Zoladex injections to keep my ovaries suppressed as well, and am therefore in artificial menopause. I am happy with this, as I used to have very heavy periods and bad PMS. I also have adenomyosis  and possible endometriosis, so I definitely don’t want to go on Tamoxifen as it does cause heavy periods. The last thing I want is worse periods than what I used to have. A friend of mine has been on T for about 4 years, and has irregular and heavy periods. She now possibly needs a curettage to ease her symptoms. 
    In terms of side effects, they all have similar ones. And it really depends on you, how your body will respond to each treatment. My side effects on the AI are not too bad, and as I said I’m very happy not getting my period. Plus the AI are more effective than tamoxifen. 
    Hope this helps. Sorry if I’ve confused you.
