Ethnic differences in cancer incidence and mortality exist and are probably the result of genetic and epidemiological risk factors. Genetic differences caused by founder mutations are reviewed, with special emphasis on mutations in BRCA1 and BRCA2. Germline mutations in cancer susceptibility genes h

β¦ Synopsis
provide little or no support of his concept. These include 1 ) the 1969 AFIP Fascicle on Tumors of the Peripheral Nervous System by Harkin and Reed,g wherein the term cellular schwannoma was used to denote a benign schwannoma, one cellular, exhibiting pleomorphism, both Antoni-A and B tissue, and only rare mitoses. An analogy to ancient schwannomatu was drawn, and the prognosis was stated to be that of ordinary schwannoma;
- the 1993 supplement to the AFIP Fascicle wherein Reed and Harkin do not mention cellular schwannoma but do state that it is not the intention of the term "malignant schwannoma" to imply a relationship to benign schwannoma;" 3) an article by Sordillo et a1.l' that comments upon low grade "malignant schwannoma" but does not mention cellular schwannoma; and finally 4) a 1986 article summarizing the Mayo Clinic experience with malignant schwannoma wherein caution was advised with regard to acceptance of cellular schwannoma as an entirely benign lesion until such time as more than the 11 cases were published.' '
In summary, no peer review article in the past 25 years supports the notion'that tumors conforming to the definition of cellular schwannoma are anything but benign tumors. Their importance lies in the fact that their lack of recognition by the unwary results in a malignant diagnosis and needlessly aggressive treatment.

## BACKGROUND. It seems unlikely that the large ethnic differences in prostate cancer risk can be explained completely by ethnic differences in diet or other lifestyle characteristics. Instead, the differences may be due to ethnic variation in endogenous factors, such as androgen metabolism or inh
Although female breast cancer rates are lower in China than in Western countries, rates have been rising rapidly in China. This increase may be due to changes in established breast cancer risk factors, but it is possible that exposure to occupational and environmental carcinogens in Shanghai also ha
The nation-wide Swedish Family-Cancer Database was used to analyze the risk of contralateral breast cancer among 72,092 women with unilateral breast cancer. Contralateral breast cancer, defined as being diagnosed 6 months or more after the first breast cancer, affected 2,529 women (3.5%). In a young
The aim of our study was to estimate the incidence of favorable mammographic patterns and to assess the incidence by risk factors of breast cancer. Data relate to 1,947 women aged 40-47 years who were screened by mammography every second year and whose mammographic parenchymal pattern at initial scr
