When we lived in Georgia there was a news station that had a kit with reminder stickers that they would send you. It was to remind you to do breast self examines once a month. They also reminded you to call a sister or friend and remind them too. The earlier something is detected the better.
My grandmother and my husbands grandmother both died from cancer. My grandmother had breast cancer that spread throughout and my husband grandmother had colon cancer that spread rapidly. She ignored her symptoms until she couldn't any more. Your body gives you signals all the time, remember to listen to it.
