Hi I dont mean to bother you but I am worried sick, I had breast cancer 5 years ago & was on tamoxifen.I havnt had a period for over 2 years so my doctor changed my tablets  to Letrozole which I need to be on  for the next two years only I started bleeding yesterday is this normal or is this a bad sign, many thanks,.
You need to see your doctor immediately. Stop metronome immediately and see your doctor. Metronome is given if post menopausal status is achieved and if you are bleeding then it should be stopped and cause of bleeding needs to be investigated. If the bleeding is not menopausal bleed you will be restarted on metronome again. If it is menstrual bleed then you will be started on tamoxifen again.
