For Breast Cancer "I have been on this medication for 18 months now. I have experienced severe hot flushes, which has mostly subsided. I have bouts of severe bone pain in my thighs, shins to the point where it feels like I have been beat with a baseball bat. I have insomnia along with mental confusion & short term memory loss. I get mild nausea but have probably gained 30 lbs. My arthritis in my ankles has Worsened. Not sure how much longer I can stay on this medication."

For Breast Cancer "Taking Anastrozole for three years after lumpectomy and 6 weeks radiation for stage 1BC. Lately, joint pain has been intolerable. Sometimes NSAIDS help. Exercise helps but hard to do when joints hurt to begin with. Also, can't go a whole day without having to lay down from feeling so tired. Completely fell apart on vacation. Was simply incapable of walking up a hill. So short of breath, knees and lower back pain unbearable. I had to stop every few feet and hold onto something. So far no evidence of recurrence. Will report all this to oncologist, as not sure I can continue this daily struggle. 65 feel like 85."

For Breast Cancer "Had DCIS (ductal carcinoma in situ) with Lumpectomy and 3 weeks of radiation. I was not too concerned about aromatase medication since all treatment had been problem free. I took Anastrozole 1mg for 10 weeks. After 5 doses developed severe diarrhea- 10-15 times per day. After 4 weeks insomnia and bone pain started, then hair loss. Really wondering if I am over treating this condition. Discontinued Anastrozole about three weeks ago, and all symptoms subsided. Just started on Examestane-hope this is a better alternative."

For Breast Cancer "I have been on anastozole for a year and half, was on tamoxifen for a year before but now gone through menopause. I was a fit 41 year old before, I always have horrible taste in mouth, struggle to get up to walk especially from out of bed, my joints are so painful, I struggle to grip, lost the steering wheel the other week and nearly shot off road, fuzzy head, hot sweats, think I've made the decision to come off it and hope for the best."

I did not take the medicine this morning and do not intend to continue."

For Breast Cancer "Had my first mastectomy in 2002. Had my second in 2015. My oncologist put me on Anestrozole. The hot flashes were unbearable, but are residing after a year on the med. Unfortunately now my feet are so painful to walk on I'm thinking that I would rather take my chances than deal with the pain in my feet. Having trouble with knee pain and every time I sit for more than one hour, I feel like I am 90. Hands ache and am too tired to get up and exercise. Is it really worth it? How much difference in reoccurrence does this give me now that I have had a double mastectomy?"

Arimidex (anastrozole) for Breast Cancer "I have been taking Arimidex for 5.8 years for breast cancer. I was diagnosed at 75 years old. I try to ignore side effects by keeping very active. Muscle weakness is a problem. Walking 2-3 km per day to date has worked to date. I need more arm strength. As a carer, increasing pressure from a needy spouse prevents me from continuing this program. I intend to stop Arimidex now and hope to lift the brain fog and regain my life."

For Breast Cancer "This causeed side effects in that I had rare kidney infarcts ( shower of blood clots) hit my right kidney. 6 days in the hospital with everything else ruled out. Now on Aromasin. I had symptoms early on a few months after starting Arimidex. Veins in my hands would hurt very bad than turn red/ purple and than ruptured under the skin. I also had a very painful big toe weeks before the blood clots hit. Oncologist and NP ignored my concerns and kept me on the medicine. Needless to say I have a new oncologist. Aromasin still causes the usual hot flashes, joint muscle pain, fatigue and nausea. But better on all of those symptoms than I was with Arimidex. Good luck ladies!"

For Breast Cancer "I started anastrozole one year ago in June 2014 after a double mastectomy. I did not need chemo or radiation as I caught the cancer early and my Oncotype DX score was very low. The first 3 months I didn't notice any side effects. But then I gained(so far) 10 lbs. and I am very active and work out 5 days a week with weights and cardio(I am 60 yrs. old now) My hips, lower back especially left side and knees hurt allot and my knees feel weak. It makes it very difficult to get up off the floor. Also both thumb joints hurt all the time. No hair loss or nail issues but some hot flashes. I wonder if it will get worse-still have 4 years left."

For Breast Cancer "Diagnosed with breast cancer 5 years ago. Took 15 double radiation treatments and been on Anastrozole for 5 years. When I finish this prescription I will be through. I must be the lucky one. I had no side affects other than the normal aches and pains that happen to older people. I had a friend who would not take this and she lived 3 months after her surgery. If the doctor says you need it, please take it."

For Breast Cancer "Diagnosed in 1/2016: Estrogen receptive intraductal papillary carcinoma, left breast. Lucky to have a lumpectomy & clear margins. No lymph nodes. However, had a heart attack & quad bypass a week later. So--no radiation on orders of the Cardio Dr. No Tamoxofin since heart disease is a side effect. Began Arimidex in April. I am up 30 #, the hot flashe/night sweats are horrible, tired all the time, no sex drive, vaginal dryness (taking osphena for that which helps), depressed, short of breath. So far no joint pain but swelling in my feet if I sit too long. Everyone says "excercise!" but it's hard to do that when I just want to sleep! Wondering if it is worth it for the small % it can offer."

For Breast Cancer "I had Stage 1 Breast Cancer, lumpectomy followed by radiation. I was put on anastrozole after my radiation and stayed on it for 6 months. The side effects were miserable. I decided that quality of life is so worth it. What I didn't know at the time was the lingering effects. My joints in my thumbs still ache, I have osteopenia and now my feet are starting to have neuropathy. This all from only 6 months taking the anastrozole and only increasing my life span by 1 percent. If I had it to do all over again, I would just say NO!!!!"

For Breast Cancer "I started on tamoxifen, 2- 3/4 years ago. I was a mess. Some of it could have been just the dealing with the actual "cancer", working as usual and going to radiation daily for 7 wks. However, I was also going through menopause and teaching about 100 kids/day, in elem. art. I was very emotional and had a lot of high anxiety. My oncologist was thinking about taking me off it, because my quality of life wasn't so good. I finally reached the post-menopausal stage and he switched me to anastrozole. I've been on it for about a year, maybe a little longer. I do have some memory problems. I took up tai chi 4 months ago and feel much better, mentally. My last visit to the oncologist, all my vitals had improved immensely! I credit tai chi for it!"

For Breast Cancer "I have been taking this medication for the last 2 months I am 52 years old. I already had some joint pain from slight arthritis in my lower back hips and hands I now have joint pain and soreness almost everywhere. I cannot seem to lose any weight which my doctor has advised and my word loss and short-term memory is not good. I kind of thought this was all in my head but I see from reading these blogs that this is what can happen. I hope it passes"

For Breast Cancer "Began taking this med about a month ago. So far, have NO sweating, but the arthritic pain is pretty high. Arms fall asleep when sleeping in most positions other than sleeping on my back. Have also noticed "tingling" on the left forward part of my brain. Comes and goes. Hair loss, but not extensive. Finding it difficult to tie shoe laces - middle finger, left hand--knuckle keeps popping (painful). Lots of soreness and stiffness in the upper part of my spine. Yesterday (8/4) thought I had a chunk of donut stuck in my esophagus but I can still feel something there today. Will need to contact oncologist for guidance on that."

For Breast Cancer "I wish I would've been told quality of life would be so severe. Been on Anastrozole for 3 years-severe hot flashes, mood swings-the medication doesn't work-but oncologist insist I take it-I do incase they test for it. Fond natural rhubarb helped me 100% get rid of my hot flashes-Not covered under insurance $35.00. My bones ache now when it's cold, different aches & pains daily. They deny osteoporosis due to the pill-But never had this kind of pain-my hips actually hurt when cold they can't move. I have 7 more years- I do not think I can stay that long-with these bone issues & mood swings-Hot flashes make me smell like a man who has not showered & just played sports -his underarm smell-This is due to the radiation treatment."

For Breast Cancer "I was on Tamoxifen for 3 years until I had to have a hysterectomy and then my doctor switched me to Anastrozole. I only have 3 more months to go and I am marking the days off on my calendar. I have gained 30 pounds, my grip strength is gone. My hands and feet tingle often during the day. My joints hurt all the time. I can't begin to tell you how my lower back feels. If I sit for too long my joints get stiff and it's hard for me to get going. I will stick it out."

For Breast Cancer "Small breast cancer ductal, non invasive, no node involvement. Had lumpectomy surgery and radiation 10/2019. Arimidex for 7 months daily. Slight stiff neck 2 months into taking drug but very brief. Biggest problem was confused brain and terrible memory, some fatigue. Brain and memory back to normal now for 73 yr old. Began exercising at YMCA daily when I felt stronger and go almost every day. Fatigue disappearing, no other side effects from the Arimidex. Plan to take it for the 5 years ."

For Breast Cancer "Am on brand name anastrazole/ Arimidex almost a year now for early stage invasive breast cancer. I developed unabating severe hot flashes, several times per hour, which are mostly controlled now with low dose venlafaxine 12.5 mg twice a day. I have lost weight, which is good. The most disturbing side effects are neurocognitive, i.e., thinking slower, forgetting little things, misreading, having to write more things down. I feel like my previously very high IQ has dropped at least 30 points."

For Breast Cancer "I have ductal carcinoma in situ (DCIS) at 70 yrs old. Was told the anastrozole would affect legs and possibly cause osteoporosis. I am one year into it and have 4 more to go. My leg pain (especially lower - like shin splints) keep me up at night. Better when standing. Lying down in supine position seems to trigger it. Hands are weak, but until after reading these comments I had no idea this may be the cause for that as well. Having hard time holding onto things. I seem to be a little forgetful, but that could just be my age. I'm sharing all unusual feelings as it may help someone else relate as it did me after reading some of these. I'm afraid to take tamoxifen as it is known to cause vaginal bleeding. Don't need that! Now Dr. says to try letrozole if I really can't deal with the pain. Being 70, I need my legs to be in good working order - the grass isn't always greener, but I think I'll give it a try."

For Breast Cancer "Diagnosed with ER+, PR+ but negative on other indicators for bilateral breast tumors. Left side, 2.4 cm one + lymph node, right side, 6 mm, lymph negative. Had lumpectomies Sept. 2019, radiation for 6 weeks to breasts and left shoulder. Oncotype DX shows low scores if I do radiation and anastrozole. I have osteoporosis already, probably due to celiac disease, so have auto-immune issues. Had my first injection of Prolia and started the anastrozole today. I am willing to give it a try, but may stop it if the side effects are intolerable. Pretty nervous about side effects, mainly bone pain and dizziness so far. I am going to try some supplementation with magnesium, and of course calcium and Vit. D, but they tend to flare up bladder pain--going to try mindfulness meditation, my physical therapist says there's lots of research that it helps with healing. Glad to find this site so I don't feel like I'm all on my own in this. Thanks to everyone!!"
