When did chemotherapy become used to treat cancer?
The use of chemotherapy to treat cancer began at the start of the 20th century with attempts to narrow the universe of chemicals that might affect the disease by developing methods to screen chemicals using transplantable tumors in rodents.
How long does it take for chemotherapy to cure cancer?
When cure is the treatment goal. Adjuvant chemotherapy (therapy after surgery has removed all visible cancer) may last 4-6 months. Adjuvant chemotherapy is common in cancers of the breast and colon. In cancers of the testis, Hodgkin and non-Hodgkin lymphoma, and leukemias, length of chemotherapy treatment may be up to a year.

How is modern chemotherapy different from Old chemotherapy?
Modern chemotherapy no longer relies exclusively on drugs that are, in essence, poisons. Targeted therapies have been developed that substitute subtle intervention for brute force, aiming to disable or block processes that enable cancer cells to grow, divide and spread.
When did chemo start being used for cancer?
The era of cancer chemotherapy began in the 1940s with the first use of nitrogen mustards and folic acid antagonist drugs. The targeted therapy revolution has arrived, but many of the principles and limitations of chemotherapy discovered by the early researchers still apply.

This led to the introduction of vinca alkaloids as anticancer agents in the 1960s. Examples include vinblastine used to treat Hodgkin's disease and vincristine used to treat pediatric leukemia. Over the next two decades, combination chemotherapy regimens started to gain popularity.
Is mustard good for lymphoma?
The use of nitrogen mustard for lymphomas gained popularity in the United States after the publication of the article in 1946. Nitrogen mustard and other derivatives of mustard gas are called alkylating agent due to their ability to alkylate molecules including protein, DNA and RNA.
When was chemo first used?
Chemotherapy was first developed at the beginning of the 20th century, although it was not originally intended as a cancer treatment. During World War II, it was discovered that people exposed to nitrogen mustard developed significantly reduced white blood cell counts.
When did cytotoxic agents start being used for cancer?
The scientists found that the patients tumour masses were significantly reduced for a few weeks after treatment and although the patient had to return to receive more chemotherapy, this marked the beginning of the use of cytotoxic agents for the treatment of cancer. The initial study was done in 1943 and the results were published in 1946.
Who discovered mustard in the 1940s?
In the 1940s, two prominent Yale pharmacologists, Alfred Gilman and Louis Goodman examined the therapeutic effects of mustard agents in treating lymphoma. First, they established lymphomas in mice and showed that the tumors could be treated with mustard agents.
What is the role of folic acid in DNA?
Folic acid, a vitamin crucial for DNA metabolism (the significance of DNA was not known at that time), had been discovered by Lucy Wills, when she was working in India, in 1937. It seemed to stimulate the proliferation of acute lymphoblastic leukemia (ALL) cells when administered to children with this cancer.
What was the first chemical warfare agent?
The beginnings of the modern era of cancer chemotherapy can be traced directly to the German introduction of chemical warfare during World War I. Among the chemical agents used, mustard gas was particularly devastating. Although banned by the Geneva Protocol in 1925, the advent of World War II caused concerns over the possible re-introduction of chemical warfare. Such concerns led to the discovery of nitrogen mustard, a chemical warfare agent, as an effective treatment for cancer. Two pharmacologists from the Yale School of Medicine, Louis S. Goodman and Alfred Gilman, were recruited by the US Department of Defense to investigate potential therapeutic applications of chemical warfare agents. Goodman and Gilman observed that mustard gas was too volatile an agent to be suitable for laboratory experiments. They exchanged a nitrogen molecule for sulfur and had a more stable compound in nitrogen mustard. A year into the start of their research, a German air raid in Bari, Italy led to the exposure of more than 1000 people to the SS John Harvey 's secret cargo composed of mustard gas bombs. Dr. Stewart Francis Alexander, a lieutenant colonel who was an expert in chemical warfare, was subsequently deployed to investigate the aftermath. Autopsies of the victims suggested that profound lymphoid and myeloid suppression had occurred after exposure. In his report, Dr. Alexander theorized that since mustard gas all but ceased the division of certain types of somatic cells whose nature was to divide fast, it could also potentially be put to use in helping to suppress the division of certain types of cancerous cells.

What was the first surgical innovation?
The discovery of general anaesthesia in the middle of the 19th century set off a golden age of surgical innovation. The American surgeon William Halsted pioneered radical cancer operations, attempting to outpace tumour growth by more and more extreme removal of tissue, in the belief – only partly true – that recurrence meant that some of the tumour had been left behind. He proved that surgeons could remove cancers, but whether patients were thereby cured was less clear. Some were, most were not.
What was the first anti-cancer drug?
Anti-cancer drugs made their entrance in the 1940s. In a grim paradox, the first was nitrogen mustard , a poison gas used to slaughter soldiers in the trenches of the First World War. Soldiers who survived exposure to it suffered the destruction of their lymphocytes – white blood cells – and needed regular blood transfusions. This selective action against a particular type of cell suggested that nitrogen mustard might be used to treat lymphoma, a tumour of the lymph system. It worked and nitrogen mustard , rechristened mustine, became the first licensed chemotherapy agent.
What was the first chemo drug?
It worked and nitrogen mustard, rechristened mustine, became the first licensed chemotherapy agent. Other drugs appeared in rapid succession, some triggered by biological insight, others by pure guesswork. One of the most striking of the former was aminopterin.
How does radiation work?
They did not fully understand why, but we now know that the treatment worked by breaking the DNA that is found in every cell and controls the process of cell division. Radiation kills healthy cells as well as cancer cells, but cancer cells are easier to kill because they are dividing faster.
Why did the first cancer hospital in France move from the city of Reims?
1779 The first cancer hospital in France is forced to move from the city of Reims because people feared the disease would spread throughout the city. 1838 German pathologist Johannes Müller demonstrates that cancer is made up of cells and not lymph, but he believes cancer cells did not come from normal cells.
Where did cancer originate?
3000 BC The earliest known description of cancer is in an ancient Egyptian textbook on trauma. Known as the Edwin Smith Papyrus, it describes eight cases of tumours or ulcers of the breast that were removed by cauterisation with a tool called the fire drill. The document says of the disease: “There is no treatment”.
