It is. My friend has been battling with her cancer spreading for over 18 months and in the process suffered a heart attack and has had her lungs drained of fluid fortnightly for months. They recently operated on her lungs to help prevent the build up of fluid and thankfully this has helped. She is remarkably strong and went from being barely able to walk a few months ago to now driving occasionally again. I believe this drug has aided her substantially in her fight and am saddened that the financial aspect of treatment can't be eased a bit for her in what may be her last few months. ( hopefully years but unfortunately we don't think that's likely ):'(
