The causes of childhood cancer have been systematically studied for decades, but apart from high-dose radiation and prior chemotherapy there are few strong external risk factors. However, inherent risk factors including birth weight, parental age, and congenital anomalies are consistently associated with most types of pediatric cancer. Recently the contribution of common genetic variation to et...

Brain tumors, which is one of the destructive forms of human being’s cancers, are the second most common children’s cancers. Brain tumors may have an inherited (small percent), acquired reasons due to environmental factors. Nowadays advances in cosmetic industry have increased our ability in the field of youth and beauty.

BACKGROUND One of the long-term effects in childhood cancer survivors (CCS) is the development of second cancers. In a cohort of CCS, this study describes how second cancers were presented, the way they were diagnosed, and the knowledge CCS had about their increased risk to develop a second cancer. PATIENTS AND METHODS Selected participants were all adult five-year CCS (n = 1275) who were tre...

OBJECTIVE This paper presents the incidence rates of childhood cancers using the data obtained from Golestan population based cancer registry (GPCR) between 2004 and 2006. METHODS GPCR registers only primary cancers based on standard protocols of the international association of cancer registries (IACR). We collect data on newly diagnosed (incident) cancer cases from all public and private di...

ABSTRACT Brain tumours are the commonest solid neoplasms in children, accounting for one quarter of all childhood cancers. Our growing knowledge basic developmental mechanisms has significantly contributed to understanding pathogenesis these and is beginning impact clinical decisions on how children with diseases treated.

Childhood cancers are a broad range of diseases. Research on the chemopreventive potential of non-steroidal anti-inflammatory drugs, such as aspirin (acetylsalicylate) has yet to be fully directed towards childhood cancers. A prima facie hypothesis on salicylate and childhood cancer would therefore be based on several factors. Firstly, salicylate inhibits the production of inflammatory prostagl...
