Early findings from a randomised trial investigating the effectiveness of tamoxifen to prevent breast cancer are reported in this week’s issue of THE LANCET. Although tamoxifen reduced breast cancer incidence by a third compared with women given placebo, the authors of the study caution that it is still too early to fully assess the risk to benefit ratio of tamoxifen as a preventative strategy for breast cancer.

Tamoxifen is well known in its effect to decrease recurrence of (and death from

A review in this week’s issue of THE LANCET assesses the research which has investigated possible links between diet and cancer. A familiar conclusion is reached-cancer risk can be reduced by eating a balanced diet (including the regular consumption of fresh fruit and vegetables), combined with regular exercise and a restriction on alcohol intake.

Diet-related factors are thought to be second only to tobacco in accounting for cancer-accounting for about 30% of cancers in developed countries

Results of a new programme for treating young children with autism have shown that even the most disabled made outstanding progress. Ninety-four percent of those completing the programme so far are now able to attend a mainstream school.

The South West Autism Project (SWAP), directed by Professor Alec Webster of Bristol University and funded by Bristol City Council, was started in September 2000, following a marked rise in the number of children in Bristol being diagnosed with autism. Data f

Web sites selling the prescription-only medication ciprofloxacin (also known by its brand name Cipro®) sprang up quickly following an anthrax outbreak in October 2001, according to a new study by researchers from the Case Western Reserve University (CWRU) School of Medicine. The study, published today in the American Journal of Medicine, also found that these Web sites provided poor quality information, had inadequate consumer safeguards, and charged high prices.

On Oct. 4, 2001, the U.S. C

OHSU study suggests that HRT may act on cancer cells to produce less aggressive tumors

A study of nearly 300 breast cancer patients at Oregon Health & Science University found that women who use hormone replacement therapy (HRT) have less aggressive tumors and are more likely to be diagnosed through mammograms than other methods. Also, HRT users with breast cancer had significantly better survival rates than non-HRT users. The study is published in the September issue of the journal T

Analysis uncovers unusual earthquake-related deformation, paves the way for methods to identify new active faults

On Oct. 16, 1999, approximately 37 miles from Palm Springs, Calif., a magnitude 7.1 earthquake ripped through 28 miles of faults in the Mojave Desert. Because of the area’s sparse population and development, the massive quake caused virtually no major measurable injuries or destruction.

Yet the “Hector Mine” event, named after a long-abandoned mine in the area, ha
