Please chime in--for those with low bmi(weight) are you ER+ or ER-

[Lani]

We have previously commented on increasing bmi(weight) being inversely proportional to development of her2 positive breast cancer (ie more skinny people get her2 breast cancer). Here looking at ALL breast cancers they feel it is the ER- breast cancers which are NOT associated with increased bmi (weight). Of those who posted regarding their weight (or lack of it)--could you pipe in again regarding whether you were ER- or ER+. Her2 seems to be a different type of breast cancer altogether, but as they are lumping her2+ER+ in with other "luminal" subtype breast cancers, it would be interesting to see if in our small group of selected (talented, passionate, communicative participants on this board) her2 positive patients low bmi is associated with her2 even in the face of ER positivity.

Just a thought!
