My oncologist and I had a detailed conversation about concerns with taking Anastrozole, 6 weeks before I started the drug. (I had to finish radiation treatments first). Fortunately for me I have already been taking Calcium and D3 for several years and have had 2 DEXA scans prior to be being diagnosed, so the baseline was there. (I have osteopenia). I also started taking Collagen 3 months prior to starting the drug to help strengthen my hair. I also have been taking a cholesterol drug for about 18 months prior to diagnosis (mine is high genetically); and one final note, I already have a low WBC and have had it for at least 15 years, so my oncologist told me that since I've been checked for abnormalities and leukemia in the past and all my tests were negative, that I am just one of those people for whom a low WBC is 'my normal'.
Having prefaced all these areas for which I had concerns, I had my first month blood review and all my bloodwork was normal. I also have had no side effects to speak of, and my hair stylists told me just this week that I have new hair growth in my part (Go Collagen!). Fingers crossed that all the supplements I already had built up in the my system beforehand, with the addition of Collagen only, have helped to prevent sore joints, hair thinning, a lower white count, high cholesterol - all things that concerned me initially. Of course I'm only one month in and I have 4 years and 11 months to go - lol - but so far, so good. I also hope that adding some weight bearing exercises to my routine will help to strengthen my bones even more.
That's my story so far - as always my thoughts and prayers for everyone on their respective journeys as well.
