Colds May Trigger Childhood Cancers

Tiger4 writes "BBC News is reporting that the incidence of childhood cancers may be affected by the colds that child has had. From the Article: 'Scientists have found further compelling evidence infections such as colds may trigger childhood cancers. The University of Newcastle-led team looked at 3,000 childhood cancers in 0 to 14-year-olds from 1954 to 1998, the European Journal of Cancer reported. Researchers found unusual clusters of brain tumors and leukemia which were typical of infection-related disease.' As much as an 8 percent increase was observed. However, the article goes on to say that some risks go down with very early exposure to other children, 'In April, a Leukemia Research Fund study found that children introduced to nursery before the age of one were found to be at lower risk of leukemia.'"

Although I do agree with the observation of over-medication in our society (e.g. the abuse of antibiotics and the catalyzed evolution of resistant strains of bacteria), the most likely causation here is from the actual viral infection. The corona virus (i.e. "common cold") has been shown to utilize very unique and distinct replication strategies which may be causing the mutations that would lead to increased susceptibility of tumor develop. As is stated in a later comment in these topic, HPV viral expression patterns have been shown to be linked to almost all cervical cancers. There is most likely some such related mechanism of cellular disruption causing either altered expression patterns in the cells of these children or mutations affecting the proteins that are responsible for regulating cell growth (hence tumor development). What is interesting, however, is that such situations have been shown in adults many times with various viral infections which is logical when one considers the risks of cancer related to age progression.
