57, post menopause and I just noticed one breast has changed shape and now looks quite angular on the inner lower quadrant. Felt around and there's a fucking lump there. It feels hard and quite large to me - DH can feel it too and he's not the most observant of chaps. Will phone gp tomorrow but freaking out now, particularly since I've had two blood clots this year and with the second (diagnosed in July) they did a manual breast examination because of the link between blood clots and cancer. Please help me not catastrophise.
