回複：Breast Ultrasound vs Mammogram

是的，我也想問是否可以先做Ultrasound.

我朋友是very dense 的情況，在個兩國家都做過檢查，國內follow 手檢ultrasound 發現的 nodule ,國外直接mammo沒發現。


我讀到的一些資料，例如:
How does a woman know if her breasts are dense or extremely dense?

“It’s a “Catch- 22”,” said co-author Diana L. Miglioretti, PhD, a senior investigator at Group Health Research Institute who is also at the University of California at Davis. “The only standard way to determine your level of breast density is to get a mammogram. But unless your breasts are extremely dense and you have other strong risk factors, the data don’t necessarily support your starting screening mammograms before age 50.”

但是這些文獻在提出這個問題的同時，並沒有提到先做ultrasound （screening）作為一個alternative。我知道這裏有篩選和診斷的區別。如果能有選擇就好了。
