Anastrozole has ruined my bones.

Hi There

I was diagnosed with stage 2 Oestrogen positive Breast cancer in 2016. After just 3 round of chemo, my ping pong ball sixzed tumour had disappeared and the cancer had left my lymph noed. After 8 rounds a mammogram had showed that though I was clear, calcium depositis on my breast might flare up into cancer and so I had a full mastectomy of the right breast and had 14 nodes removed. The nodes came back clear and the breast was cancer free though I did have dome precancerous tissue. I had had a complete pathological response which considerably increased my odd of not having a recurrence, After some months I had my healthy breast reduced from an f to a c cup to match my new implant and the removed tissue was completely cancer free. I then began anastrzole with zoladex injections to stop my periods. I also took part in the palbocciclib trial from 5 cycles until it caused my to reject 2 implants and developed sepsis.  

After a year on Anastrozole a dexa scan showed that I had gone from moderate osteopenia -1.7 to osteoporosis -2.6. I was horrified. I asked the oncologist what my chances of recurrence were. She said 5 to 10% if I take the anastrozole and 7 to 10% if I take nothing.  So I stopped taking it. I worry that I have gone against my oncologist but if I keep taking that drug I reduce my chanced of recurrence by 2% but will definitely ruin my bones. I haven't told my oncologist yet

  • has anyone got bone pain in the shoulders through anastrozole tia

  • When I was on Anastrozole every muscle and bone in my body hurt....

  • I'm sorry, impossible to advise. All I know is that my aches and pains are so much better now off the Anastrozole. I've no intention of going back on it. I was especially worried about it affecting my bones as I have arthritis and scolosis. All I can suggest is to speak to your consultant or cancer nurse. I'm very sympathetic as I really struggled on the medication. I'm so much better off it and I'll have annual mammograms. Good luck. 

  • Hi Suemary,

    so sorry to hear about your experience. I had a mastectomy 4 years ago, didn’t require anything other than being put on anastrozole. I wasn’t given a DEXA despite having scoring 9 on the FRAX test but told I would be well monitored. The side effects were very bad for me - anxiety, intense flushes and pain. I researched extensively - the Australian NHS website was very helpful. I then consulted my surgeon as to what coming off the drug would do to my likelihood of my cancer returning. I weighed this up with the likelihood of the drug causing osteoporosis to me and my quality of life. I decided to come off the anastrozole after having taken  it for year. My symptoms reduced dramatically when I came off them.I made some pretty radical lifestyle changes to rebalance the odds in my favour. It’s a very personal decision.

    A year later I had some pretty painful musculoskeletal problems - shoulders, neck,hips and lower back. I got a DEXA scan eventually when I fractured ribs doing simple stretching exercises to release chest tightness.These showed that I was osteopenic with one hip much worse than the other which an X-ray confirmed  will need a replacement at some point. I cannot say if my year on anastrozole caused this - it will not have helped. I did not have any help from my cancer specialists to get the DEXA. Perhaps because I had stopped taking anastrozole. 

    It is not an easy choice but is ultimately yours to make with the best advice you can obtain. Your consultant should be able to give you figures for what your risk of cancer recurrence would be. It is certainly worth finding out your own facts and figures as to the adverse side effects of anastrozole or any other of the drugs you may be offered. The anastrozole is certainly extremely effective at preventing cancer recurrence according to the statistics I found in my research.

    I have found diet, exercise - Pilates classes, swimming (when available!) and walking help to maintain what I have be as pain free as is possible. I also have a very good osteopath who had me diagnosed, spot on, before my DEXA and X-rays were taken. She helps me with hands on physio and the correct exercises to strengthen and maintain muscles - I am greatly missing her during the lockdown. I did try  NHS physio, they were as helpful as they could be but ultimately  but they weren’t   hands on or specialised enough to help me. Whatever your decision on the anastrozole I would recommend that you try to access some professional Physiotherapy . Pain medication can help initially but the right physio and exercise can keep you as pain free as possible with the minimum of painkillers. Physio seems to be online at the moment but hopefully that will change soon.

    I wish you the best of luck.

  • WOW KiWiWife such a great description

    I had a mastectomy 5 years ago and will begin reconstruction next week.  I stayed on Anastrozole a total of 2 1/2 years, a break after two years and then quit short of the recommended 5 years.

    i agree with excercise, healthy eating and I drink aloe and lots of great supplements.

     

    I agree, a personal decision....

  • Hi Penelope1

    Good luck with your reconstruction, I hope that it all goes well and that you will be pleased with it. We take a lot of things for granted and only miss them when they’re gone! It’s not the same, but it is good that there are options for us - before and after surgery.

    Best wishes 

  • Dear KiWiWife, 

    You are so upbeat and informative, thank you for your thoughts.

    i really never missed my breast, I was almost 68, widowed.  Anastrozole was so exhausting and hurt so much, a breast was of no consequence, life was.

    when I quit Anastrozole, began walking, taking supplements and going back into business with old friends.  Once I felt well, I decided on reconstruction.  The epidemic was just hitting America and my scheduled surgery was canceled.  Now I am set to go, like my surgeon very much.

    a few months ago a fellow fell in love with me and I am glad I was decided on my surgery before we met, he did not want me to have it.

    There will be pain, a graft is being taken from my back, but I heal well and with the expander then implant, my right breast will be done by 12/2020 and the left breast will be done to match, 1/2021.

    i have 2 middle aged, lovely daughters, have had an adventurous life.  Being upbeat and fearless is a gift I am able to give them.

    many hugs

    I use my middle name, Paige

     

     

  • Hi sue mary and others,

     

    I had a mastectomy in February which went well with no further treatment needed but put on Anastrozole in March.  So have been on it for 4 months and joint pain/stiffness seem to be getting gradually worse, especially my hips.  i am now feeling aches and stiffness affecting me considerably, enough to consider stopping it.  Especially if there is only 1% in recurrence incidence. Interestingly to protect my bone density I was also put on a drug called Iasibon (Ibandronic acid) and was told I would not need a dexa  scan.  
     

    What does the Australian study reveal?  
     

    thank you all for you help and best of wishes to you all.
     


     

     

  • Hi annechristina,

     

    sorry to hear how the anastrozole is affecting you. If you google long term side effects and efficacy of anastrozole you will get a list of more recent studies which will inform you better of what is being found - it is still a relatively new drug for cancer treatment and not every thing is known. 

    It is a long trawl and there’s so much that you really need to look at it yourself to take what information you need to know from the studies and trials. I would look to find out what the findings/side effects are for building bone density before ascertaining the need for this and whether  a DEXA scan to determine your baseline bone density would be more beneficial before you were put on these prescriptions. The more information that you have the more that you will be able to ask your consultant the correct questions so that he/she can give you answers so you will to be able to judge for yourself what treatment is the best for you. For me it was a question of balancing one risk against another - there was nothing that gave me a perfect outcome - and asking myself how I would feel if the cancer did come back. 

    I hope this helps 

     

     

  • Hi 

    It's always reassuring to hear about other peoples experiences while taking this medication.

    I've been taking Anastrozole for just over 7 years.

    I have just found out I have high cholesterol and after a recent Dexa scan osteoporosis.

    I am coming off the medication immediately.

     

     

  • After reading these posts I have discussed with my husband and have made the decision to stop taking Anastrazole. I have done everything my consultants have advised- double mastectomy, chemotherapy and I'm still having Herceptin injections til April. Throughout, everyone around me have helped me keep a positive attitude.

    I thought I was over the worst. Then I started this treatment. After 6 months of taking my daily dose, I have gone from being a fit and healthy 59 year old, hiking for miles and regularly taking part in Body Combat, Dancersise and Aquafit classes, to feeling like an old lady with back and joint aches and pains- my back feels like it is starting to stoop. Not to mention hot flushes, bowel issues, pins and needles in my hands and dry skin. My body has been through enough and I'm not willing to forego 10 years of living a full life for minimal benefit and the risk of osteoporosis.

    Took my last one last night. Of course it's a personal decision and everyone must weigh up the pros and cons. I wish you all a happy and healthy 2021 and sending hugs to anyone who is suffering with nasty side effects. And thank you for sharing your own experiences. xx

     

     

  • Hi Sandra-Ann,

     I wish you luck. It is a personal choice - weighing up your own risks versus benefits. I managed 11 months of a 10 year course on anastrozole before coming off it because of very bad side effects. I have no regrets 4 years down the line - other than I wish I had stopped taking them earlier. If I am unlucky enough for my cancer to re emerge in the future, then so be it. I have a life I can live and appreciate now - which I lost when taking anastrozole. I wish you too, a happy and healthy 2021, getting back to the activities you enjoy.
