I feel that I need to revisit the whole letrozole thingie, just to be fair.
In my last post I expressed my frustration with the continued side effects of the estrogen-supressing aromatase inhibitors designed to reduce the risk of cancer recurrence. Cancer survivors face a considerable amount of pressure from our oncologists to stay on these medications, but everyone agrees that their use does not come without health risks or hits to one’s quality of life. The latter is a squishy concept that is not easily quantifiable.
Deciding whether to take medications for the length of time prescribed, or stop them early, comes down to an individual’s tolerance of both the side effects and risk.
So after all the complaining in my last post, the big question I have in front of me is that, given that I’m already postmenopausal — regardless of the fact that it was the medication that pushed me into menopause — if I were to stop letrozole, would I experience a significant improvement of my complaints? And if I could reverse the side effects how long would it take? None of that is clear.
Granted, there remains additional risk in taking an aromatase inhibitor, particularly long-term, as the cessation of estrogen production contributes to aging and age-related maladies, including heart issues, bone loss and broken bones. And certainly, there is gradual collagen and hair loss, not to mention suppression of the libido.
But if we ignore that for now, I have to admit that not all days are as bad as how I described them. I don’t lie in bed staring at the ceiling while every single side effect hits me all at once. I experience them here and there. And most of them are tolerable.
My fear is about the future. If I’m feeling this now, what will it be like in another six months or a year? What if things go downhill gradually and I don’t realize it until later when I’ve slid so far down that nothing is salvageable. That’s completely ignoring the realities of the “now” for the imagined troubles of tomorrow. That is not being mindful!
But unfortunately, with medications such as these, the future is a factor that must be taken into account, and with that comes anxiety. Of course, anxiety always makes things worse. For me, it’s one of the most difficult side effects of cancer, because it magnifies all the negatives, both real and imagined.
I realized after I submitted the last post, after I complained about all the things I was experiencing, that not everything was as horrible as I thought. Things are not “normal”, and the situation is still applying a frustrating pressure on my quality of life. But maybe, for now, can I hold on and get the most out of the benefits of letrozole, and then re-evaluate tomorrow?
WARNING: IF YOU ARE STARTING ON AN AROMATASE INHIBITOR, I highly recommend that you not read this and instead give yourself the chance to gauge the medication’s effects without being influenced by someone else’s experiences. Note that I started letrozole just out of menopause, so my side effects from this drug have been more dramatic than they might be for a women who’s been postmenopausal for longer.
When it was time to start letrozole, I took a different tack than when I began tamoxifen. For the latter drug, I did all the research I could, researching relevant studies, digging into possible side effects and visiting lots of forums to learn about what other women were experiencing.
I wish I hadn’t. I think all the negatives affected my perception and made me anxious about taking the medication.
So after two years of tamoxifen, when my hormone levels suggested that I was postmenopausal and it was time to switch to an aromatase inhibitor, I stayed away from clinical literature about letrozole. I decided to give it a chance, since my oncologist felt that I had confused the effects of anxiety about taking tamoxifen with the actual effects of tamoxifen.
Okay, then. As I was leaving my oncologist’s office, letrozole prescription in hand, he added that some women complain of “joint pain”. I think he felt it was his duty to warn me.
My experience? I’m finding it harder to recover from workouts. I train with free weights and am a rower (currently, indoor) and the change in my resilience and stamina is striking. In 2018, a year after finishing up chemo, I was able to power through tough workouts and felt like I’d gotten most of my pre-cancer strength back.
Fast-forward to now, just two years later, I feel old. My joints are creakier and I’m having increased muscle pain and overall stiffness. I’m experiencing bone pain in the leg that I broke skateboarding when I was 12. Yeah, I push through workouts, but they’re taking their toll on me.
I’m fortunate to have a full complement of gym equipment at home, so the COVID-19 lockdown didn’t hinder my workouts. To get some fresh air, I incorporated more hiking into my routine, in addition to my regular workouts.
It was too much and left me with hip pain that made it difficult to fall asleep. So I took a rare break from vigorous workouts and for two weeks incorporated more gentle movements and focused on yoga, which I had been doing intermittently.
When I started ramping back up, I didn’t feel rested, I felt weak! Weights that had been easy to lift a couple of weeks before felt challenging. I had to restart the process of building my strength. You could pass it off as simply “age”, but I’m only 54, and the drop in strength and energy has felt precipitous, even demoralizing. While it’s true that I went through menopause during the last two years, it was a medication-induced menopause and I was literally shoved through the change.
Letrozole has been shown to be very effective in preventing cancer recurrence, presumably because it works to keep estrogen levels low. However, most women on letrozole are in their 60s and have been postmenopausal for a number of years. For a woman in her 50s, the aging effect of estrogen suppression has felt dramatic.
My libido dipped even lower than I’d experienced with tamoxifen, something I was warned about by my GP and gynocologist (both females). My male oncologist didn’t talk about it. I believe this is a seriously underreported side effect of aromatase inhibitors and one that many women suffer from in silence, because they don’t feel comfortable bringing it up.
Likewise, I feel my appearance changed. Now, this may simply be my perception of myself, as my post-chemo hair transitioned from super-cool and spikey to thin and limp (and, now, untrimmed!), and my eyebrows never recovered. But it’s not just in my head: A bus driver recently tried to offer me a senior citizen discount, whereas four years ago someone had told me they thought I was in my late 30s! That’s a big difference. The fact that the lack of estrogen is making me look like I’m older than I really am has become distressing:
And that difference is felt in my relationship with my family. There have been times that I’ve looked at my husband (four years my junior) and my high school-aged kids, and I feel like don’t belong with them. I feel like a stranger, an old lady that’s just hanging around. That hurts a lot.
And on my worst days, I feel dark clouds rolling in, bringing with them frustration and hopelessness. Is it letrozole or menopause? Does it even matter? Take a woman, throw her in a bag, tie it to a tree branch and then beat it with a stick. That is how I feel when I have to take a pill that does these things to me. No control, no future, lots of pain. The longer that I continue with medications like this, the more I feel that they are pointless, since I’m starting to not care whether or not the cancer comes back. And that’s the worst side effect of all.
So, this blog is about being honest about the cancer experience. But it’s also about mindfulness. I have to open the door and let the negative feelings into the room so that I can offer them compassion and a kind ear. I sit with them for a while, and eventually, I feel better.
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?
More than two years after finishing chemo, after being afraid my hair would not grow back, and after being delighted with the way it did…I’m experiencing follicular drama, once again.
Once chemo was over, my sleepy follicles took their time getting roused into action. To say that I worried would be an understatement. I was still caught up in the unfairness of being smacked down by breast cancer. Confronting the possibility that after enduring the nastiness of cancer treatment, I might not get my hair back? That was too much.
Well, if you’ve read my posts on hair, you’ll know that my hair finally did come back. And there was much rejoicing.
And that’s where my hair posts stopped. But as happens with these kinds of things, that wasn’t the end of the story.
While still bald, I had been fed reassuring anecdotes by well-meaning supporters about hair coming back even better than before, lush locks that served as well-deserved rewards for undergoing the anxiety and strain of cancer diagnosis and treatment.
But as much as cancer patients feel like they don’t know what’s going on, those around them have even less of an idea. They want you to “stay positive” at all costs, so they overload you with lots of good news.
By now you can probably guess where I’m going with this. Because in Spring 2019, things started changing. Within a few months, my uber-cool spikey rockstar hair lost fullness as my strands thinned. Then, I saw “bald spots”.
So, let me explain how I define “bald spots”: these areas have hair, but due to the color (um, WHITE) and thinness, the hair seems translucent, even transparent. And along the part? You can’t see the roots well at all.
My reward for enduring cancer is invisible hair.
My hairstylist confirmed that the hair that comes back in after chemo is different from the hair that eventually settles in. And mine had settled.
Tamoxifen also played a role, since choking off estradiol and moving into menopause will age both you and your hair, particularly if you are premenopausal going into treatment, as I was. So this should have been expected, but in the hustle and bustle of all the other little things, like, oh, wondering if you’re going to survive the ordeal, no one really talks about the fact that there will be other changes that take place.
And now, I’ve been off tamoxifen for almost six weeks, but can’t tell whether there’s been any regrowth, not that I expect any. I meet with my oncologist this Tuesday and you can bet your panties he’s going to prescribe an aromatase inhibitor for me, so the pharmaceutical depression of estrogen will continue.
I am dealing. Mostly. Am I happy about this? Of course not. The last few years have felt like running a gauntlet of misery, but one where I’m only hobbled and not completely taken out. Given that, I’m ashamed of complaining, as there are many others doing so much worse. But not ashamed enough to stop writing about it, as this is my reality and it affects me. If I’m going through this, there’s a good chance that many others are too.
I’m supposed to be moving on and leaving cancer behind me, right? But like an annoyingly nosy neighbor, it keeps waving at me through my kitchen window, reminding me that it’s living next door.
This weekend would have marked two years of taking tamoxifen, the estradiol-blocking medication that is supposed to keep my hormone-positive breast cancer from recurring.
As it turns out, there will be no such commemoration. Several weeks ago, I started noticing a funny cramping feeling in the general area of my uterus. It was light and under any other circumstances, I would have ignored it, but use of tamoxifen is associated with an increased risk of endometrial/uterine cancer, so it kept me on edge.
It’s worth noting that the increased risk is actually for postmenopausal women, and to the best of my knowledge, I was not yet postmenopausal. That’s why pre- and perimenopausal women are started on tamoxifen but taken off of it as soon as they go through menopause. Still the sensation, although intermittent, didn’t go away.
I finally called my oncologist. As it was, I was wary of tamoxifen – I already blamed it for a number of other negative things that I experienced: fatigue, hair thinning, low libido, cognitive issues, mood swings, general misery…all of those and more were listed as possible side effects.
I complained about the light cramping to an oncological nurse, who was surprised that I didn’t have a recent pap smear on record, because according to her, the oncologist wanted me to have one yearly. Mind you, pap smears are for cervical cancer, and I wasn’t at an increased risk for that. But whatever. The nurse gave me her blessing to stay off tamoxifen until I next saw the oncologist.
Conveniently, my oncologist appointment was in three days.
I was stressed, because if there’s one thing that being a cancer survivor made me good at, it was stressing. So much so, that my blood pressure hit 165/95 at my appointment. I couldn’t get over how ridiculous that was and how my thoughts had generated that sort of a reaction. I don’t think my pressure was even that high before my cancer surgery, at a time when my anxiety was raging and everything felt out of control.
I had a prolonged discussion (negotiation?) with my oncologist. In the end, we decided the following: I could take a month off tamoxifen and meet with him again in six weeks. In the meantime, I would go to my gynecologist to rule out endometrial cancer. (Incidentally, a week later at the gynecologist’s office my blood pressure was back down to a very reasonable 102/64.)
My oncologist and my clinical counselor (who I discovered had spoken to him about me) thought that some of the worst side effects that I was experiencing were not due to tamoxifen, but anxiety. My onc suggested that if nothing improved after a month off tamoxifen, I should consider anti-anxiety meds.
But he also checked my hormone levels to see where I was in my journey into menopause. A few days later, I got the news: I was officially postmenopausal and was told to not restart tamoxifen.
So, okay, no more tamoxifen. I was also quite happy that I managed to transition through menopause without any significant hot flashes. The downside of this was, however, that I would be put on an aromatase inhibitor, which came with its own set of side effects, not the least of which was significant bone pain and bone density loss.
Or at least those were some of the effects that I remembered from the last time that I read about them, which was a while ago. This time, I’ve decided, I won’t go back and research all the negatives of the medication. Anxiety does hit me hard, I have to admit, and I want to be sure that I’m really experiencing what I’m experiencing and not simply being influenced by what I’ve read.
So I’ll give the new medication a fair shake and give myself a break by not getting worked up by what *might* happen. As the gynecologist said, looking over my bloodwork, “Actually, you’re really healthy, except for having had breast cancer.” I’m going to go with that and see where it takes me.
