Hi! @timely :

I am so sorry for all you've been through, my comrade; surely fighting the disease of BC is no walking in the park:(

Could you please let us know the reason for avoiding taking calcium tablets, please? I know 3 doctors had avised you on this, but did they give you the reason why?

Prayer for you and all of us for better health with plenty of pleasure enjoying beloved family on journey ahead!

Hi. I take Toremifene which is a “serm” to tamoxifen. Fewer side effects for me than anastrozole. I am 72 years old. Way past menopause. Estrogen positive.

My gynecologist before BC surgery, My first cardiologist before and after surgery and my ongoing medical oncologist all said not to take calcium tablets.

I have arrhythmias.
The calcium tablets can cause obstruction in blood vessels and the heart as they can stay there and form calcium deposits.

I think that the cardiologist was concerned that tablets can put calcium deposits in blood vessels.

Gynecologist just said to not use when I saw her before my lumpectomy.
