That last sentence was crucial. Albeit crudely, Hunter had begun to classify tumors into “stages.” Movable tumors were typically early-stage, local cancers. Immovable tumors were advanced, invasive, and even metastatic. Hunter concluded that only movable cancers were worth removing surgically. For more advanced forms of cancer, he advised an honest, if chilling, remedy reminiscent of Imhotep’s: “remote sympathy.”*
Hunter was an immaculate anatomist, but his surgical mind was far ahead of his hand. A reckless and restless man with nearly maniacal energy who slept only four hours a night, Hunter had practiced his surgical skills endlessly on cadavers from every nook of the animal kingdom—on monkeys, sharks, walruses, pheasants, bears, and ducks. But with live human patients, he found himself at a standstill. Even if he worked at breakneck speed, having drugged his patient with alcohol and opium to near oblivion, the leap from cool, bloodless corpses to live patients was fraught with danger. As if the pain during surgery were not bad enough, the threat of infections after surgery loomed. Those who survived the terrifying crucible of the operating table often died even more miserable deaths in their own beds soon afterward.
In the brief span between 1846 and 1867, two discoveries swept away these two quandaries that had haunted surgery, thus allowing cancer surgeons to revisit the bold procedures that Hunter had tried to perfect in London.
The first of these discoveries, anesthesia, was publicly demonstrated in 1846 in a packed surgical amphitheater at Massachusetts General Hospital, less than ten miles from where Sidney Farber’s basement laboratory would be located a century later. At about ten o’clock on the morning of October 16, a group of doctors gathered in a pitlike room at the center of the hospital. A Boston dentist, William Morton, unveiled a small glass vaporizer, containing about a quart of ether, fitted with an inhaler. He opened the nozzle and asked the patient, Edward Abbott, a printer, to take a few whiffs of the vapor. As Abbott lolled into a deep sleep, a surgeon stepped into the center of the amphitheater and, with a few brisk strokes, deftly made a small incision in Abbott’s neck and closed a swollen, malformed blood vessel (referred to as a “tumor,” conflating malignant and benign swellings) with a quick stitch. When Abbott awoke a few minutes later, he said, “I did not experience pain139 at any time, though I knew that the operation was proceeding.”
Anesthesia—the dissociation of pain from surgery—allowed surgeons to perform prolonged operations, often lasting several hours. But the hurdle of postsurgical infection remained. Until the mid-nineteenth century, such infections were common and universally lethal, but their cause remained a mystery. “It must be some subtle principle140 contained [in the wound],” one surgeon concluded in 1819, “which eludes the sight.”
In 1865, a Scottish surgeon named Joseph Lister made an unusual conjecture on how to neutralize that “subtle principle” lurking elusively in the wound. Lister began with an old clinical observation: wounds left open to the air would quickly turn gangrenous, while closed wounds would often remain clean and uninfected. In the postsurgical wards of the Glasgow infirmary, Lister had again and again seen an angry red margin begin to spread out from the wound and then the skin seemed to rot from inside out, often followed by fever, pus, and a swift death (a bona fide “suppuration”).
Lister thought of a distant, seemingly unrelated experiment. In Paris, Louis Pasteur, the great French chemist, had shown that meat broth left exposed to the air would soon turn turbid and begin to ferment, while meat broth sealed in a sterilized vacuum jar would remain clear. Based on these observations, Pasteur had made a bold claim: the turbidity was caused by the growth of invisible microorganisms—bacteria—that had fallen out of the air into the broth. Lister took Pasteur’s reasoning further. An open wound—a mixture of clotted blood and denuded flesh—was, after all, a human variant of Pasteur’s meat broth, a natural petri dish for bacterial growth. Could the bacteria that had dropped into Pasteur’s cultures in France also be dropping out of the air into Lister’s patients’ wounds in Scotland?
Lister then made another inspired leap of logic. If postsurgical infections were being caused by bacteria, then perhaps an antibacterial process or chemical could curb these infections. It “occurred to me,”141 he wrote in his clinical notes, “that the decomposition in the injured part might be avoided without excluding the air, by applying as a dressing some material capable of destroying the life of the floating particles.”
In the neighboring town of Carlisle, Lister had observed sewage disposers cleanse their waste with a cheap, sweet-smelling liquid containing carbolic acid. Lister began to apply carbolic acid paste to wounds after surgery. (That he was applying a sewage cleanser to his patients appears not to have struck him as even the slightest bit unusual.)
In August 1867, a thirteen-year-old142 boy who had severely cut his arm while operating a machine at a fair in Glasgow was admitted to Lister’s infirmary. The boy’s wound was open and smeared with grime—a setup for gangrene. But rather than amputating the arm, Lister tried a salve of carbolic acid, hoping to keep the arm alive and uninfected. The wound teetered on the edge of a terrifying infection, threatening to become an abscess. But Lister persisted, intensifying his application of carbolic acid paste. For a few weeks, the whole effort seemed hopeless. But then, like a fire running to the end of a rope, the wound began to dry up. A month later, when the poultices were removed, the skin had completely healed underneath.
It was not long before Lister’s invention was joined to the advancing front of cancer surgery. In 1869, Lister removed a breast tumor143 from his sister, Isabella Pim, using a dining table as his operating table, ether for anesthesia, and carbolic acid as his antiseptic. She survived without an infection (although she would eventually die of liver metastasis three years later). A few months later, Lister performed an extensive amputation144 on another patient with cancer, likely a sarcoma in a thigh. By the mid-1870s, Lister was routinely operating on breast cancer and had extended his surgery to the cancer-afflicted lymph nodes under the breast.
Antisepsis and anesthesia were twin technological breakthroughs that released surgery from its constraining medieval chrysalis. Armed with ether and carbolic soap, a new generation of surgeons lunged toward the forbiddingly complex anatomical procedures that Hunter and his colleagues had once concocted on cadavers. An incandescent century of cancer surgery emerged; between 1850 to 1950, surgeons brazenly attacked cancer by cutting open the body and removing tumors.
Emblematic of this era was the prolific Viennese surgeon Theodor Billroth. Born in 1821, Billroth studied music and surgery with almost equal verve. (The professions still often go hand in hand. Both push manual skill to its limit; both mature
