text: Hello! Yes it could be Breast Cancer, but it could also be a long list of many other things or Nothing at all, but a muscle ache.  I know breast pain can be a scary thing.  If you are concerned about your health then the best thing you can do for yourself is see your family Dr. and talk to him or her about your health.  I hope that it ends up being nothing.  Breast Cancer more time then not doesn't cause any pain.  check out the website http://www.plwc.org and click on Breast Cancer and then on symptoms.  You can will be able to find a lot of information on there. Best of luck to you! Take Care.
