I've just been diagnosed with
'Bilateral invasive breast cancer. Left side multifocal Grade 2 ductal. One focus is oestrogen and progesterone positive and HER2 negative and the other is triple positive.
Right side Grade 1 invasive lobular cancer oestrogen and progesterone receptor positive HER2 negative'
My feeling this isn't very common?
I wonder if there is any research regarding the percentage of women diagnosed with three different primary breast cancers involving both breasts. Also regarding prognosis.
Thank you
