Hi, I have hard thickening in my left breast at the top it’s felt hard for a year now it’s gone massive then smaller, then softer and now I just always feel dense tissue, I’m 20 years old. My left breast to me is obviously harder and thicker tissue than my right. I have had it checked three times where I have been told I don’t need a scan. I have ocd and anxiety and I’m genuinely worried. I have two young children and I’m terrified.
