Many patients came from Assiut [30.1%] and Sohag [23.4%]; male: female ratio was 1.14: 1 and the mean age of all cancer patients was 45.5 +/- 20.3. The peaks occurred at 55 years old for men and 10 years earlier for women for Assiut patients. The cancer risk was unity at age of 32 years and the peaks of risk occurred at 55 years old for men and 10 years later for women. The common cancers were breast [14.9%], lymphoma [13.6%], followed by bladder [10.8%], lung [5.5%] colon and rectum [4.2%] and liver and bile ducts [3.4%]. In males, bladder cancer [17%], lymphoma [16.8%] and lung [8.2%] were the most common cancers; while breast cancer [29.5%] and lymphoma [10%] were the most common cancers in females
