Background: Cancer is one of the most common causes of deaths in the world. Cancer incidence and prevalence is increasing in the world. There is no clear trend is available on incidence of these cancers in Iran, therefore, this study aimed to determine the incidence of 10 common cancers among Iranian women from 2003 to 2009.

Materials and Methods: A cross-sectional study was conducted by analyzing existing data. Data from a national registry of cancer cases were received. Data included the records from the cancer registry system in Iranian women during 2003 to 2009. The incidence rates were then standardized using direct method. We used Cochrane Armitage Test for linear trend by Winpepi software to determine the variation in the incidence of cancers.

Results: The results show that the proportion of all cancers is rising in women as compared to all population. Breast, skin, colorectal, gastric, esophageal, thyroid, leukemia, ovary, brain and uterus were the most common cancer among Iranian women. During the years of the survey, these cancers are significantly increased.

Conclusion: The results of this study showed that the incidence of cancer in women is increased. screening programs can be useful in reducing the cancers.

Background: Cancer in the elderly is rising increasingly. According to the population structure in Iran, it is necessary to conduct a study to examine the epidemiology and trends in cancer incidence in the elderly in Iran. So, the aim of this study was to investigate the epidemiology and trends in cancer incidence in Iranian elderly from 2003 to 2009.

Materials and Methods: This cross-sectional study was conducted by analyzing existing data obtained from the National Cancer Registry System in Iran. In this stucly, all records of elderly cancer cases in Iran during 2003 to 2009 were investigated. The age- specific incidence rates of reported cases were estimated by using direct standardization method and the world standard population. We used Cochrane Armitage Test for linear trend by Winpepi software to study the trends in cancer incidence.

Results: stuolying statistics of Cancer Registry center shows that the incidence of cancer increases with age and most cases of cancer occur commonly in elderly people (aged over 60), so that, the highest number of cancer cases diagnosed in people aged 80-84, but it decreases after the age of 85. The most common cancer among the elders, in this period (2003-2009), was the skin cancer. Also, according to the statistics, cancers are more prevalent among older men than older women.

Conclusion: with due attention to the results, the trend of incidence of cancer and its various types in the elders is increasing with age. The implementation of screening programs and necessary trainings in the field of early detection and the avoidance of exposure to risk factors to reduce the risk of cancer in Iranian elderly can be useful.
