While much recent research has not been published in this area, there is actually a long history of studies that show: (1) there is a significant number of antigens shared between

tumor development significantly earlier than the non-stressed mice.16 Other mouse studies of ovarian cancer showed that chronic stress resulted in increased cancer growth as well as increased angiogenesis, the process
