Data from a large, population-based case-control study were analyzed to investigate the relationship between prenatal exposure to tobacco smoke and childhood brain tumors (CBTs). A total of 540 CBT patients, diagnosed between 1984 and 1991, were identified from population-based tumor registries in

The etiology of childhood brain tumors (CBTs) remains unknown. Tobacco smoke contains several known carcinogens and can induce DNA adducts in human placenta and hemoglobin adducts in fetuses. We present the results of an international case-control study to evaluate the association between CBTs and

Brain tumors are the second most common cancer in children after leukemia, yet the etiology of childhood brain tumors remains unknown. Tobacco smoke contains several dozen compounds that are known to be carcinogens. Among these are N-nitroso compound precursors, principally tobacco-specific

OBJECTIVE The California tobacco control program enacted in 1988 has been associated with declines in smoking and heart disease mortality. Since smoking also causes lung cancer, we investigated whether the program was associated with a decline in lung and other cancer incidence. METHODS Age-adjusted

The roles of diet and tobacco in the etiology of primary brain cancer are controversial. In this report, we compare dietary and cigarette smoking histories among 434 adults newly diagnosed with glioma in the San Francisco Bay Area (California, USA) between 1991 and 1994 with frequency age, gender,

Radiation therapy is a major cause of long-term complications observed in survivors of pediatric brain tumors. However, the effects of low-doses of ionizing radiation (IR) to the brain are less studied. On the other hand, tobacco is one of the most heavily abused drugs in the world. Tobacco is not

The aim of the paper was to evaluate the association between preconceptional and prenatal exposure to tobacco smoke and the risk of all cancers combined and separately, for brain tumors, leukemias, lymphomas and other childhood cancers. We conducted systematic search of the literature using PUBMED,

Childhood brain tumors (CBT) are the leading cause of cancer death in children, yet their etiology remains largely unknown. Tobacco smoke contains 61 known carcinogens and increases the risk of several adult cancers. This study investigated associations between parental smoking and risk of CBT in a

Experimental evidence suggests that parental exposure to polycyclic aromatic hydrocarbons (PAH), which occurs primarily through tobacco smoke, occupational exposure, and air pollution, could increase the risk of cancer during childhood. Population-based case-control studies carried out in seven

Numerous studies have increasingly suggested that medical history and lifestyle factors could be involved in the increase of cancer risk in adults. The issue whether psychological factors can influence the development of cancer has been discussed for many years. In the field of brain cancer,

BACKGROUND Tobacco metabolites and carcinogens can be found in placental and umbilical cord tissues of fetuses exposed to maternal smoking. However, studies regarding maternal smoking during pregnancy and childhood brain tumor (CBT) have shown inconsistent results. METHODS All children born in

Malignant brain tumors are the leading cause of cancer death among children and the second most common type of pediatric cancer. Despite several decades of epidemiologic investigation, the etiology of childhood brain tumors (CBT) is still largely unknown. A few genetic syndromes and ionizing

Associations between primary brain tumor mortality and dietary habits, certain serum biochemical markers, and life-style factors were evaluated in a county-based correlation study utilizing data collected from an ecological survey in 49 Chinese rural counties. Univariate correlation and multivariate

A population-based case-control study of incident primary malignant brain tumours diagnosed during 1985 to 1989 in children aged 0 to 14 years was carried out in the coastal conurbation of New South Wales comprising Sydney, Wollongong and Newcastle in the period 1988 to 1990. Personal interviews
