The key ideas in The Emperor of All Maladies

Cutting wider and deeper

In the 1890s the surgeon William Halsted popularised the radical mastectomy, removing the breast with the chest muscles and nearby lymph nodes. He believed wider surgery meant more cures. It stayed standard for decades, until a trial led by Bernard Fisher in the 1970s found smaller operations did as well.

The war on cancer

Farber teamed up with Mary Lasker, a wealthy New York campaigner, to press Washington for money. Their push helped win the National Cancer Act, signed by President Nixon in 1971. Supporters hoped for a cure within a few years. Progress was far slower, because cancer is many diseases.

Stopping it before it starts

In 1775 the London surgeon Percivall Pott noticed that chimney sweeps, sent up chimneys as boys, often got a cancer rare in other men. He blamed the soot. In 1950 Richard Doll and Austin Bradford Hill tied lung cancer to smoking. Prevention became a second line of attack.

Aiming at the broken gene

From the 1970s, scientists showed cancer begins with damage to our own genes, often ones that tell a cell when to divide. In chronic myeloid leukaemia, a blood cancer, a single faulty gene drives the disease. A drug built to block its protein, imatinib (Gleevec), was approved in 2001.

Lines worth underlining

  1. Old enemy

    Cancer is ancient. Doctors in Egypt described it thousands of years ago.

  2. Our own cells

    Cancer is our own cells growing out of control, which is why it's so hard to kill.

  3. Radical surgery

    Halsted's surgeons cut away more and more, but that didn't save more lives.

  4. First drugs

    Sidney Farber's drugs pushed back childhood leukaemia for a while and started modern chemotherapy.

  5. Tobacco

    Proving that smoking causes lung cancer turned prevention into a real weapon.

A story from the book

Sidney Farber's gamble

In 1947 the Boston pathologist Sidney Farber tried a new drug, aminopterin, on children with leukaemia. It blocked folic acid, which the cancer cells needed to multiply. Some children improved for months before the disease returned. Those short remissions showed a drug could hold cancer back.

Hot take · true or myth?

The biggest possible dose of chemotherapy always works best.

Myth. In the 1990s thousands of women with breast cancer had huge doses of chemotherapy, then a bone marrow transplant. Careful trials found no benefit, and the one glowing study had been faked.
