return of periods after 5yrs of tamoxifen

Hi my name is Georgina I’m 42 I was diagnosed with breast cancer 4 years ago I had no chemo but I had a lumpectomy radio for three weeks and zoledex injections every three months over 2 years today I started having a period and I was just wondering if this is normal I haven’t had a period for at least 3 years and because my cancer was musicinious carcinoma is it dangerous

Hi ladies I’m a fourteen months after stopping tamoxifen, had a bleed had scan biopsys no cancer thicken lining small cyst on ovary, scan again in September, just finished a 13 day heavy bleed, it’s not nice after 6 years no periods going through the change and feel back to square one, will have an hysterectomy I think but the thought of another menopause fills me with despair but in a positive note no cancer again, just go with the motions again, worst bit waiting took three weeks for biosopy results xx

See gp get a scan and biopsy done hopefully just a reaction from the drugs xx
