Virgil Craig Jordan, CMG, OBE, FMedSci, (July 25, 1947 – June 9, 2024) was an American and British scientist specializing in drugs for breast cancer treatment and prevention.

Previously, he was Scientific Director and Vice Chairman of Oncology at the Lombardi Comprehensive Cancer Center of Georgetown University.

Jordan was the first to discover the breast cancer prevention properties of tamoxifen and the scientific principles for adjuvant therapy with antihormones.

[2] His later work branched out into the prevention of multiple diseases in women with the discovery of the drug group, selective estrogen receptor modulator (SERMs).

Jordan's research showed that post-menopausal women who took these drugs did not suffer from a lowering of bone density or an increase in blood cholesterol.

He was appointed Officer of the Order of the British Empire (OBE) in the 2002 Birthday Honours for services to international breast cancer research.

He has recently published work showing that estrogen, given at the right time, causes the destruction of cancer cells rather than feeding their growth.

[17] 2002 made an Officer of the Order of the British Empire by Queen Elizabeth II for services to international breast cancer research.
