i need to know if i have breast cancer. about three to four weeks ago i got a huge painful cyst under my left armpit so i waited and it popped then as soon as it popped another grow back that was just as painful i then got a third one but it wasn't as bad as the other one's. i then got pimples between the top and bottom of my armpit where they touch. ( between triceps and biceps and along my ribs). i then got a small pimple right by my left nipple which i popped but now there is a lump that feels just like the cyst under my arm but its not painful but it is a little black and blue. im also starting to grow a cyst under my right armpit. what could this be
