Breast cancer can take decades to develop, so “early” detection via mammogram may be too late. The breast cancer you may feel one day as a lump in the shower, may have started 20 years ago.  We now suspect that all the epithelial cancers: breast, colon, lung, pancreas, prostate, ovarian-the ones that cause the vast majority of cancer deaths-take up to 20 years or more to manifest. By the time it’s picked up it may have already been growing, maturing, scheming for years, acquiring hundreds of new survival-of-the-fittest mutations to grow even quicker and better undermine our immune system. Early detection may in effect be really, really late detection.

People are considered “healthy” until they show symptoms, so if we’ve been harboring a malignancy for 20 years we may feel all right, but we haven’t been. Thus, many people who do the right thing and improve their diet in hopes of preventing cancer may, at that very moment, be treating it as well. In this way, cancer prevention and treatment may sometimes be the same thing.

What new developments are there are in the battle against breast cancer? Well, most breast tumors are estrogen receptor positive, meaning they respond to estrogen; estrogen makes them grow. The problem for tumors in postmenopausal women is that there isn’t much estrogen around-unless of course you take it in a drug like Premarin (so-named because it’s made from pregnant mare urine). Premarin appears to increase the risk of breast cancer (as well as strokes, heart attacks, and blood clots). Unfortunately, the plant-based bioidentical hormone replacement therapies don’t appear any safer (see my 4-min. video Plant-Based Bioidentical Hormones).
