cancer tumour in the heart

two people have contacted me-one is amazingly similar to our circumstances-same age-same symptoms-we are both going into chemo at the same time frame-only-we are 1 week ahead-we start carboplatin and taxol on monday-is there anyone else out there who has a massive tumour behind the heart .in the heart or near the heart that is causing the heart to go into afib because the heart is being srtressed-please lets all work together to help each other-this tumour is running rampant-the growth and movement in 1 month is scary-is it because it has a blood suppy that is unlimited-meaning the heart    this tumour is a lung cancer tumour that is out of control-perhaps you have heard of something like this-or maybe the person passed away already -but-please please let us know-thanks so much
