I don't really feel that you need a second opinion BUT if you are as concerned as I gather from your post then by all means get one. We are always entitled to a second opinion in any situation where we are left with questions or concerns. If you only had the Ultrasound, why not request a mammogram and then take both sets of films when and if you do see another surgeon.
I think you need a second opinion! I am 51 I have implants never a moments problem... I went for an mamagram a month ago and afterwards they send me a letter stating i need to get an ultrasound.... they found a suspicious spot.
i have to go this week. i am very scared but trying to be positive. it has been 2 weeks since this letter and just last week i noticed a dull achy pain in my breast around the 2:00 or 3:00 area and it it dull with a sometimes sharp pain.
we will pray for eachother..
God Bless
