graying hair and a salt-and-pepper beard. Along with Henderson, he is an eminent figure in cancer research, but no one would ever accuse him of being tentative in his pronouncements. “We understand breast cancer extraordinarily well. We understand it as well as we understand cigarettes and lung cancer.”
What Pike discovered in Japan led him to think about the Pill, because a tablet that suppressed ovulation — and the monthly tides of estrogen and progestin that come with it — obviously had the potential to be a powerful anti-breast-cancer drug. But the breast was a little different from the reproductive organs. Progestin prevented ovarian cancer because it suppressed ovulation. It was good for preventing endometrial cancer because it countered the stimulating effects of estrogen. But in breast cells, Pike believed, progestin wasn’t the solution; it was one of the hormones that caused cell division. This is one explanation for why, after years of studying the Pill, researchers have concluded that it has no effect one way or the other on breast cancer: whatever beneficial effect results from what the Pill does is canceled out by how it does it. John Rock touted the fact that the Pill used progestin, because progestin was the body’s own contraceptive. But Pike saw nothing “natural” about subjecting the breast to that heavy a dose of progestin. In his view, the amount of progestin and estrogen needed to make an effective contraceptive was much greater than the amount needed to keep the reproductive system healthy — and that excess was unnecessarily raising the risk of breast cancer. A truly natural Pill might be one that found a way to suppress ovulation without using progestin. Throughout the 1980s, Pike recalls, this was his obsession. “We were all trying to work out how the hell we could fix the Pill. We thought about it day and night.”

Pike’s proposed solution is a class of drugs known as GnRHAs, which has been around for many years. GnRHAs disrupt the signals that the pituitary gland sends when it is attempting to order the manufacture of sex hormones. It’s a circuit breaker. “We’ve got substantial experience with this drug,” Pike says. Men suffering from prostate cancer are sometimes given a GnRHA to temporarily halt the production of testosterone, which can exacerbate their tumors. Girls suffering from what’s called precocious puberty — puberty at seven or eight, or even younger — are sometimes given the drug to forestall sexual maturity. If you give GnRHA to women of childbearing age, it stops their ovaries from producing estrogen and progestin. If the conventional Pill works by convincing the body that it is, well, a little bit pregnant, Pike’s pill would work by convincing the body that it was menopausal.
In the form Pike wants to use it, GnRHA will come in a clear glass bottle the size of a saltshaker, with a white plastic mister on top. It will be inhaled nasally. It breaks down in the body very quickly. A morning dose simply makes a woman menopausal for a while. Menopause, of course, has its risks. Women need estrogen to keep their hearts and bones strong. They also need progestin to keep the uterus healthy. So Pike intends to add back just enough of each hormone to solve these problems, but much less than women now receive on the Pill. Ideally, Pike says, the estrogen dose would be adjustable: women would try various levels until they found one that suited them. The progestin would come in four twelve-day stretches a year. When someone on Pike’s regimen stopped the progestin, she would have one of four annual menses.
Pike and an oncologist named Darcy Spicer have joined forces with another oncologist, John Daniels, in a startup called Balance Pharmaceuticals. The firm operates out of a small white industrial strip mall next to the freeway in Santa Monica. One of the tenants is a paint store, another looks like some sort of export company. Balance’s offices are housed in an oversized garage with a big overhead door and concrete floors. There is a tiny reception area, a little coffee table and a couch, and a warren of desks, bookshelves, filing cabinets, and computers. Balance is testing its formulation on a small group of women at high risk for breast cancer, and if the results continue to be encouraging, it will one day file for FDA approval.
“When I met Darcy Spicer a couple of years ago,” Pike said recently, as he sat at a conference table deep in the
