Jimmy Carter says cancer has spread to brain

Jimmy Carter, the former US president turned Nobel peace laureate and global humanitarian, revealed Thursday he has cancer on his brain but said he feels at peace and grateful for having lived a full life. The 90-year-old Carter told a press conference that the finding of the four melanoma spots stemmed from a procedure in which a tumor was removed from his liver earlier this month. "They did an MRI and found that there were four spots of melanoma on my brain," Carter told reporters in Atlanta.
