oh ps DM,

methotrexate doesn't cause breast health issues.
however, being on low dose methotrexate for MS can possibly cause the growth of tumors (anywhere in the body). it depresses the immune system hopefully reducing sx's of MS.

my dr said it's a very low chance but there is a chance. so, i'll be watching this carefully. i may request a biopsy even if they think it's nothing. they may want to watch it for a few months and test again. who knows.

i'm trying not to jump to conclusions and live in the moment.
but, my nursing knowledge trumps that common sense sometimes.
