Hi I've discovered a funny knobbly long shaped lump in my right breast. Been referred to the beast clinic for a mammogram on Friday. I'm a bit worried. I had a look on my nhs app and the dr has clicked the over 30 suspected cancer box. Is it the norm to click that box when they don't know what it is? I would feel a bit better if it was a smooth round lump but the thick long gristley feeling thing is now making me worry if it's something sinister. (I'm 30 and not been for a mammogram before)
