Dragon boat team of Breast Cancer survivors:

My mom found her lump 'totally out of the blue' one day while she was getting her swim suit on. It wasn't high up though more along the side sort of close the to the nipple. She said it was the size of her thumb. By the time the did her mastectomy it was over 5cm in size. She said her self exam the month prior, it was not there nor was it in her mammogram six months prior.
