Hi-Ho, Hi-Ho, On Letrozole We Go

Starting up again…

After giving me a six-week respite from tamoxifen and then running bloodwork that revealed I was postmenopausal, my oncologist made good on his threat to put me on letrozole, an aromatase inhibitor. This breast cancer medication is supposed to block “the enzyme aromatase, which turns the hormone androgen into small amounts of estrogen in the body. This means that less estrogen is available to stimulate the growth of hormone-receptor-positive breast cancer cells” (breastcancer.org). It’s also better suited for postmenopausal women.

Not gonna lie, I really did not want to go on yet another medication, but for this appointment, I left all the journal articles at home and put away the boxing gloves. I promised my oncologist that I would stay off the forums, stay off PubMed, quit overthinking things and give letrozole a chance.

The reason? My oncologist thinks that my earlier frustration with tamoxifen was, to put it bluntly, in my head. And my clinical counselor suggested that what I complained of could be explained by anxiety. But I swore that my memory and focus issues started with tamoxifen.

You know what? I’m not so sure now.

The fact is, everything that I was experiencing could have been caused by anxiety (or menopause). And even more striking were the things that I didn’t experience. Not only did I not have significant hot flashes (maybe a “warm flush” here or there, easily countered by taking off a sweater), I never had night sweats. Heck, I had more night sweats before my cancer.

No weight gain, either, which had been another big concern of mine. I’ve been disciplined in maintaining healthy fitness habits throughout my adult life, probably to the point that most people wouldn’t tolerate. Tamoxifen didn’t manage to mess with that, which was extremely gratifying.

While I really want to peg the concentration problems, distractability, flagging libido and other negatives on estrogen-blockers, a retrospective look at my emotional history suggests that (1) I’m highly suggestible (I need to stay off the internet!), (2) there have been loads of anxiety-amplifying events in my life, even before cancer, that I haven’t handled well, and (3) I would be better off shutting up, taking the pill and working on getting my mental state in order.

I mean, I already knew most of this. But some things need to hit me between the eyes a number of times before they actually register.

So, while my oncologist warned me about “a little joint pain” (eek!), I’ve avoided anything but a cursory glance at what I might experience on letrozole, besides what reactions would necessitate calling the doctors.

We’ll see how bad these side effects really are.

A FINAL NOTE – According to what was written on the bottle, this stuff can cause dizziness and impair my ability to operate a vehicle. Seriously? I didn’t expect that, but here’s what I’m going to do with that tidbit of information: I’m going to view letrozole as a reason to get to bed earlier, since I’ll obviously have to take it in the evening. And I’m going to tell myself that this is going to help me sleep. Who knows, maybe it will?
