@Jackie My goodness sorry to hear of your story! I went through the same thing with my Mum she had BC at age 40 though had a Mastectomy and NO TREATMENT, she was 26 years Cancer Free. At Age 66 she developed Lung Cancer after back pain that landed her in Emergency. She was a smoker, however the Cancer was at the back of the Lung and metastasized to her back muscle. It was such a shock, she passed within 6 weeks. This also occured on the same side as her BC, but she did not have radiation, she was a smoker, and they say it was unrelated. Jackie, I honestly don't necessarily believe that will be you at all. Eventhough I got BC same side as my Mum, the Specialists were emphatic it was unrelated to the BC. Hugs day at a time Melinda xo
