I am sorry you lost your mother to Cancer, I too lost my mother from it , she had Ovarian Cancer , but she had her Ovaries removed in 1992 but still got it in 2001, but kept coming back to different areas of her body , she died in 2011 , so I understand it is difficult to watch a love one go thru that , my younger brother died of Colon cancer in 2010, his was more aggressive ,
