There are two things about your post that concern me. The first, of course, is the drainage. I am glad your doctor is keeping an eye on that.
The second thing that concerns me are the calcifications. Are they macrocalcifications or microcalcifications? I had a lot of microcalcifications on my diagnostic mammogram and I ended up being diagnosed with: ductal carcinoma in situ (DCIS), invasive ductal carcinoma and a colloid (spelling?) carcinoma.
Another question - are you having any other symptoms? Are you feeling fatigued? Can't sleep even though you feel tired? Is your stomach constantly upset? These are all symptoms of breast cancer. I learned this from www.breastcancer.org. You might want to check out that site.
Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid. John 14:27
