text: The only way to know for sure is to go to your doctor. I found a lump some months back and went to the doctor straight away, mainly as I was worrying and panicking like crazy!\nThey sent me to see a specialist and after an examination and what was just like having an ultra sound on my breast they told me it was just swollen glandular tissue.\nIts a painless procedure and it will put your mind at rest. Cysts do need treating too, they often need to be drained which is not a big deal and easily done. If it is something that needs treating its better to get it done sooner rather than later. Good luck!
