This collaboration started in 1995 and this report is the fith published report. I would like to congratulate and thank everyone involved in this project - the doctors and nurses from MOHSS collecting data; the CAN staff doing data entry and follow-up; IARC doing data- analysis and the sponsors involved in producing the report. Without the hard work of each individual this very important research project would not be possible. This information is essential for the action that must be taken by the Namibian National Cancer Control Program – another collaborative program to start soon. In our collective battle against cancer our vision and mission is to: 1. Prevent cancers - create awareness, provide education about healthy lifestyle, promote HPV vaccination 2. Promote early detection - screening 3. Provide information about the most common cancers in Namibia 4. Provide adequate medical treatment for all Namibian cancer patients 5. Provide palliative and supportive care for all Namibians This battle can only be fought by a multidisciplinary team which include MOHSS, CAN, all healthcare professionals, the government of Namibia, the media, churches, NGOs and every Namibian citizen. With sincere gratitude Annelle Zietsman Dr. A.B. May Cancer Care Centre – Windhoek Central Hospital MOHSS A SPECIAL THANK YOU A special word of thanks to Morten Ervik of IARC for help answering many questions relating to CanReg5 software. The Cancer Association of Namibia would like to thank all medical practitioners, medical and treatment establishments and volunteers who have supported data collection. We would also like to thank the African Cancer Registry Network (AFCRN) for their continued support on cancer reporting in not only Namibia, but Africa as a whole. 2 CONTENTS Message from the Cancer Association of Namibia (CAN) and Namibia National Cancer Registry (NNCR) ......
