I'm 24 years old and felt a lump in my breast, had my appointment at the breast clinic on Monday and they said its a 25mm solid mass on the US and took a core biopsy. I have heard other people my age being told they have a fibroadenoma just through the US alone, no need for biopsy. Is the fact that they took a biopsy at my age a bad sign? I'm freaking out. The doctors were also very elusive and did not give me much information.
