question: Hi. I had breast cancer 5 years ago . I now have a bruised feeling on the under edge of my bottom left rib quite near to the centre of chest. I sometimes think it feels like a mass or lump to touch. Last week I noticed a severe pain which made me cry out. It was very localised pain. It only lasted a second like I had pricked myself with something sharp. This happened 3 or 4 times in a space of a couple of days. Now it just feels bruised to touch under the rib just to left of sternum.
