My Mom had three sisters; two of them were stricken with breast cancer. One passed away a few years ago; the other has suffered with complications and side effects for more than 40 years. The up-side is she survived; the down side is her quality of life hasn't been that great.
When the breast cancer drug Tamoxifen was in clinical trials a few years ago, my Mom felt a responsibility to participate. She volunteered to be a part of the study for a couple of years. So, she's kind of my breast cancer hero, too. She took a chance ~ not knowing what the drug may do. Fortunately she didn't experience any side effects and is still healthy as can be.
Mom turns 92 on Friday. One of the gifts I'm giving her is this super soft (think angora/cashmere) pink hat I knit for her, with a special little note from me. ;-)
