I am currently on Femara for about a month now, after failure of both Abraxane and Xeloda. I had been on tamoxifen for 4 years after my initial stage III diagnosis but stopped it when it came back. After doing the chemo and rads, the dr. said, "You know, just because tamox failed you doesn't mean you can't try another hormonal. Since chemo hasn't really worked, let's try Femara."

Okay, fine. But for the first time these past few weeks I have been feeling pain in the spine where the tumors are. Before, I hadn't felt anything. Well, I know they progressed from the scan in April, but it's kind of scary to actually feel it.

So my question is, could it just be that it takes time? I really hate that I could be feeling bad and the cancer could be improving, OR I could be feeling great and the cancer is progressing, there is no way to know. Sigh...How long does Femara take to "kick in"?!? Or is this a wash, already?

I can only speak for myself.  I started Femara ( along with Zometa) in January after finding mets to spine and hip.  I think I really started to notice a difference ( meaning decreased pain, feeling stronger etc... in April). Interestingly my improvement coincided with some hair loss and  increased hot flashes.  My tumor markers went down by 100 which indicates something  is working.  I think the Zometa is helping more with the decreased pain in my back ( I have compression fractures in T8 and 9) and x-rays of my hip which fractured and required pinning in January, show increased calcium deposition.    I have PET scans Tuesday so I guess I will find out then if all of this is doing the trick.   I sure hope you are feeling better soon.

Femara worked GREAT for me when I first started taking it....I went into remission (but not NED) in about 3 months.  That must be the magic number for hormone treatment because that is how often we scan. When I asked him about my latest one, which I've been taking about a month, he said it was too early to tell.  Like you, I have been having pain in the areas where the mets are and I have not had this before. When I asked about that, he said any new treatment can cause a "flare", but said again that it's too early to make any conclusions on if it is working or not.  Hope this helps.

I don't have a scientific answer to your question, but I'll share my experience.  Since starting Femara I've had more twinges and random aches/pains, but after getting scan results today I feel like those twinges are because the treatment is working not because of progression.  I've been on Femara for about 2 months.

Also, my 75-year-old mom, who is also stage 4 has been on Femara for about 10 months and she is in complete remission.  She's never felt better.

I think I'm becoming a Femara evangelist.  :-)

I took Femara for almost 2 years and was doing pretty well.  I was better on the very first scan after starting it (3 months).  My doc says that's a pretty standard amount of time for the hormonals to start working.

As far as feeling pain in areas that you haven't felt before, I've had more pain sometimes when my scans are a little better.  My onc says that with bone mets, sometimes the mets are providing structural support and when they shrink, we have pain because new bone hasn't filled in that spot yet.  That kind of made sense to me.

I hope you feel good and that Femara kicks some cancer butt for you!

Peace and hugs,

Jennifer - thank you for sharing that about the bone mets! I had not heard that before, but it does make sense.

Hi raro,

I saw your post about pain meds so wanted to reply here. I also have mets to my bones in my back. Last year when I was on the super herceptin and zometa, I started having a lot of back pain and also had pain that ran from my lower spine down my leg...i self diagnosed as sciatica. At first I suspected it was the bone mets getting worse (as did my onc), but guess what...once I went off the chemo, the pain went away. So I told my doc that I think the drugs cause so much swelling that everything is pushing on each other in my back and causing pain and he agreed. So your pain might not be from the mets but from swelling due to the chemo etc. I took aleve for my pain and also got some hydrocodone which helped when things were real bad. Hope you are doing better:) nothing worse than frigging back pain!
