Nelson Mandela

Political figure Nelson Mandela was also diagnosed with prostate cancer in 2001 after being released from prison and ending the Apartheid regime in South Africa.
At this point he retired from the public eye and entered radiation for his cancer which was successful as he has now been in remission since 2004 [Radiation treatment].
Mandela is enjoying his peaceful life with family and can credit a Noble Peace Prize to the list of accolades he has received.
