Good morning, I’m so happy that positive stories are helping. My own update is that I’m now 16 weeks in and still no side effects from letrozole. The hot flushes are diminishing , I have found that drinking coffee will spark one but that was the same when I was going through the menopause 20 yrs ago, and that is a well known trigger factor. I do take my letrozole at exactly the same time every day , I don’t know if that helps but it means that the levels of it remain pretty constant, no troughs or spikes. Last time I posted I was a week or two post radiotherapy and feeling exhausted and with pain. I am pleased to report that I no longer feel like that so the effects have been transient. I now have more energy and feel more alert than I have felt for a very long time. So…. If you’re going through post radiotherapy fatigue or are wondering how it will affect you, it will get better. My breast is still healing inside, I had a 9.9 cm lump removed weighing a whopping 10.7 oz , so it will take a little time to be completely without soreness but it will happen. In the meantime I have full use of my arm with a full range of movement and no pain , back to normal really. I notice that there is sometimes a question about which drug to use, either tamoxifen or an aromatise inhibitor like letrozole so ……. Oestrogen + cancer means that the cancer is fuelled by oestrogen, it needs oestrogen to be able to grow and multiply, so if you can stop oestrogen from getting to the cancer cell it with starve to death. JaneRu you should be able to find your score on your report, if not then your breast care nurse should be able to tell you. The higher out of 8 the score is then the more responsive it is to oestrogen and the more treatable it will be by reducing its access to oestrogen. Tamoxifen and letrozole have different mechanisms for reducing that access. Tamoxifen acts directly on the cancer cells by blocking their receptors, a bit like stitching their mouths shut. Letrozole works by reducing the amount of oestrogen you have circulating in your body, thus starving the cancer cells that way. If you are pre menopausal you don’t really want to lower your oestrogen levels as oestrogen is useful for other things too, so tamoxifen is the drug of choice as it starves the cancer cells without reducing oestrogen levels. If you are post menopausal the letrozole is the drug of choice. Oestrogen levels are lower then in any case so lowering them further and starving the cancer cells that way is very effective. in my case I was initially very reluctant to take them but given my circumstances I felt I had no choice. I’m glad I did start them now. I had a multi focal breast cancer, two invasive tumours in the same quadrant of the same breast, originating from the same source. One was just behind my nipple, the other near my chest wall, they were both 8/8 oestrogen and progesterone positive , both had lymphovascular invasion , meaning that both had invaded nearby tissue, blood vessels and lymph vessels ( my sentinel nodes were clear). Both were just under 2cms. They were 6.5cms apart and that space in between was filled with in situ carcinoma, the total size being 9.9cms. I was very lucky that my surgeon was an oncoplastic surgeon so she was able to do a huge lumpectomy and still leave me with a decent breast that doesn’t need any further reconstruction. ( she’s fantastic). My breast cancer was scored ( as is the norm), on the Nottingham scale. At the moment if you have multi focal Breast cancer it only takes into account the size of the largest tumour and not the size of the sum of all the tumours. There is ongoing debate about this as some research indicates that the accumulated size should be considered. That would certainly have put me into a different category. Also there is research indicating that lymphovascular invasion should also be used as an independent predictor, which at the moment it isn’t. So my Nottingham score indicated that I shouldn’t be offered chemotherapy. On the one hand I was relieved on the other I was anxious that it wasn’t offered. I am an ex nurse and wanted it to be treated as aggressively as possible . So…. The reason I eventually decided to take letrozole was that I felt that if a stray cancer cell or two had moved out of my breast via my blood vessels , then I didn’t want it to set up shop anywhere else, so starving it of oestrogen with letrozole was my best option as I wasn’t offered chemo ( which I would have taken in a heartbeat). oh yes. About the bone thing. Reducing oestrogen will have an effect on your bone density which is why we have an initial density scan before taking letrozole to get a base level. If any bone density levels are a bit lower than they should be ( and they often are after the menopause), then you should be offered treatment, advice and further monitoring scans later during your treatment. I am scheduled for two years hence. Im sorry I seemed to have rambled a bit this morning, this is a long post but if it makes anything any clearer for any one then it’s been worth it. Please take care of yourselves and each other, big hugs to you all , ❤️ ❤️ ❤️ ❤️
