Everything Has A Rhythm In Life Including Hormones

The problem is one of “priming.”

The estrogen must create the internal environmental potential for the progesterone to wipe out the growth and start over again. One just doesn’t work properly without the other. They are for lack of a better term, “in tandem” rhythmically as long as a woman is young, healthy and fertile. It is impossible to be one out of that list of three without the other two.

That’s why the menstrual cycle has two peaks that cease to be when one goes missing.

Everything alive has a rhythm.

The world as we know it, from bacteria to blue whales, the whole universe, in fact, is all about timing, within each of us and in relation to everything outside us. The individual rhythms overlap into larger patterns that then weave in and out of each other. Human beings swim in and out of this sea of rhythms. The moon provides more lightwith its full face and sure enough as the new moon ends, every twenty-eight days females bleed.

The circadian clock in every cell of our body measures one spin of the planet, and the moon tracks the repeating 28 of those days 13 times in one revolution around the sun. In the female menstrual cycle, there’s a peak of estrogen and then a peak of progesterone. If one imagines that picture strung together over a year, one month connected to the next, there’s a rhythm of unending ups and downs. It’s a balancing act.

Estrogen’s solo in the first half of our cycle sets the stage for pregnancy all over our body. Estrogen grows, hence its reputation in cancer research. But estrogen, by way of creating progesterone receptors, has sealed its own fate. Progesterone generated by the popping of the egg, steps on stage to end that song of creation.The progesterone that we make naturally, in the second half of our cycle when we’re young, protects us from cancer on the molecular level. Natural progesterone is a genomic effecter for apoptosis. (In English: natural progesterone latches on to switches on the genes called promoter regions for “cell suicide.”) Cell suicide is the mechanism that causes the death of the one for the good of the many.

Natural progesterone in a normal menstrual cycle controls the destruction phase which kicks in about half way through your cycle when no conception has occurred. It’s only when we stop popping eggs and producing progesterone regularly as we head toward menopause -- that estrogen can continue to grow cells unchecked.

And this doesn’t just happen in the uterus, either.

These rapidly multiplying estrogen-driven cells exist in our breasts and brain, too, and they have progesterone receptors on them. The receptors are waiting for progesterone to signal the final act. The chemical listening for that signal from progesterone will go on indefinitely as long as estrogen continues to pour, unless we artificially replace from the outside the natural hormones we lack.

Does estrogen cause cancer? No or all young women would be dead.

Can estrogen cause cancer? Yes, but only in the absence of progesterone.
