What is chemotherapy used to treat?
Treat cancer Chemotherapy can be used to cure cancer, lessen the chance it will return, or stop or slow its growth. Ease cancer symptoms Chemotherapy can be used to shrink tumors that are causing pain and other problems.
How long does chemotherapy last for cancer treatment?
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.
What is the history of chemotherapy?
History of cancer chemotherapy. 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 had arrived, but many of the principles and limitations of chemotherapy discovered by the early researchers still apply.
How does chemotherapy kill cancer cells?
Chemotherapy not only kills fast-growing cancer cells, but also kills or slows the growth of healthy cells that grow and divide quickly. Examples are cells that line your mouth and intestines and those that cause your hair to grow.
When did we start using chemotherapy 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.
How long has the idea of chemotherapy been around?
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.
What is the oldest form of cancer treatment?
The first cancer to be cured was choriocarcinoma, a rare cancer of the placenta, using methotrexate which is still a useful drug 60 years later.
When was cancer treatment first used?
The first cancer case cured exclusively by radiation occurred in 1898.
What was chemo originally used for?
The era of chemotherapy had begun. Metastatic cancer was first cured in 1956 when methotrexate was used to treat a rare tumor called choriocarcinoma. Over the years, chemotherapy drugs (chemo) have successfully treated many people with cancer.
Why do we still use chemotherapy?
To be sure, chemotherapy is still used a lot for its ability to kill cancer cells, even in clinical trials that involve newer treatments like immunotherapy. Sometimes, fast-acting chemotherapy can help slow an aggressive cancer, for instance, and give the slower-acting immunotherapy treatments a chance to work.
How was cancer treated in the 1950s?
Prior to the 1950s, most cancers were treated with surgery and radiation. During the period 1949–1955, the only marketed drugs for the treatment of cancer were mechlorethamine (NSC 762), ethinyl estradiol (NSC 71423), triethylenemelamine (9706), mercaptopurine (NSC 755), methotrexate (NSC 740), and busulfan (NSC 750).
How was cancer treated in the 60s?
Damaging surgery and relatively unsophisticated radiotherapy were the main treatments, assuming the disease was detected in time for anything to be done. Today's diagnostic tests, keyhole surgery, highly targeted radiotherapy and arsenal of cancer drugs were far beyond the imagination of the doctors at that time.
What is the most used cancer treatment?
Any cancer treatment can be used as a primary treatment, but the most common primary cancer treatment for the most common types of cancer is surgery. If your cancer is particularly sensitive to radiation therapy or chemotherapy, you may receive one of those therapies as your primary treatment.
Why has cancer become more common?
The main reason cancer risk overall is rising is because of our increasing lifespan. And the researchers behind these new statistics reckon that about two-thirds of the increase is due to the fact we're living longer. The rest, they think, is caused by changes in cancer rates across different age groups.
Do we all have cancer?
No, we don't all have cancer cells in our bodies. Our bodies are constantly producing new cells, some of which have the potential to become cancerous. At any given moment, we may be producing cells that have damaged DNA, but that doesn't mean they're destined to become 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.
When was methotrexate first used?
In 1951 , Jane C. Wright demonstrated the use of methotrexate in solid tumors, showing remission in breast cancer. Wright's group were the first to demonstrate use of the drug in solid tumors, as opposed to leukemias, which are a cancer of the marrow. Several years later at the National Cancer Institute, Roy Hertz and Min Chiu Li then demonstrated complete remission in women with choriocarcinoma and chorioadenoma in 1956, discovering that methotrexate alone could cure choriocarcinoma (1958), a germ-cell malignancy that originates in trophoblastic cells of the placenta. In 1960 Wright et al. produced remissions in mycosis fungoides.

Abstract
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.
Introduction
In the early 1900s, the famous German chemist Paul Ehrlich set about developing drugs to treat infectious diseases. He was the one who coined the term “chemotherapy” and defined it as the use of chemicals to treat disease.
The Early Period of Cancer Drug Development
A selected history and timeline of events related to the development of cancer chemotherapy is shown in Fig. 1. The first four decades of the 20th century were primarily devoted to model development.
World War II and the Immediate Post-War Period
Although gases were not used on the battlefield in World War II (WWII), a great deal of research was done on vesicant war gases ( 5, 8 ).
The 1950s
The 1950s were a period of undue pessimism due to the disappointment over the failed promise of nitrogen mustard to produce durable remissions. This negative view was somewhat offset by the discovery of corticosteroids, which were to be used in cancer patients but were also quickly found to produce only brief responses when used alone ( 31, 32 ).
The 1970s: The Age of Adjuvant Chemotherapy
The concept of cure had a remarkably permissive effect on the use of chemotherapy in earlier stages of cancers. For example, about 90% of patients with breast cancer present with locoregional disease. Yet, the majority will develop recurrences if only the best locoregional treatment is used.
Passage of the Cancer Act of 1971 and Beyond
One unanticipated benefit of the report of the curability of choriocarcinoma, lymphomas, and acute leukemias with combination chemotherapy was the passage of the National Cancer Act in 1971.

How often is chemo given?
Chemotherapy is commonly given at regular intervals called cycles. A cycle may be a dose of one or more drugs on one or more days, followed by several days or weeks without treatment. This gives normal cells time to recover from drug side effects. Sometimes, doses may be given a certain number of days in a row, or every other day for several days, followed by a period of rest. Some drugs work best when given continuously over a set number of days.
What is the best way to treat cancer?
Chemotherapy refers to the use of any drug to treat any disease. But to most people, the word chemotherapy (or "chemo") means drugs used for cancer treatment. It's important to know that not all medicines and drugs to treat cancer work the same way. It used to be that the only kind of drug that could treat cancer was traditional or standard chemo, but now there are a lot of different kinds of drugs used to treat cancer. While traditional or standard chemotherapy is still the best way to treat many cancers, different kinds of drugs may work better for others.
What is the term for shrinking a tumor before surgery?
To shrink a tumor before surgery or radiation therapy. Chemo used in this way is called neoadjuvant therapy .
Why do people need chemo?
When the cancer is at an advanced stage, probably cannot be controlled, and has spread, the goal of giving chemo may be to improve the quality of life or help the person feel better. For instance, chemo may be used to help shrink a tumor that’s causing pain or pressure so the patient feels better and has less pain.
What is radiation therapy?
Surgery removes a tumor from a part of the body where cancer has been found, and radiation therapy is aimed at a certain area of the body to kill or damage cancer cells. Treatments like these are called local treatments because they affect one part of the body.
Does chemo cure cancer?

Overview
Targeted therapy
Molecular genetics has uncovered signalling networks that regulate cellular activities such as proliferation and survival. In a particular cancer, such a network may be radically altered, due to a chance somatic mutation. Targeted therapy inhibits the metabolic pathway that underlies that type of cancer's cell division.
Beginnings
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 trea…
Antifolates
Shortly after World War II, a second approach to drug therapy of cancer began. Sidney Farber, a pathologist at Harvard Medical School, studied the effects of folic acid on leukemia patients. 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 prolif…
6-MP
Joseph Burchenal, at Memorial Sloan-Kettering Cancer Center in New York, with Farber's help, started his own methotrexate study and found the same effects. He then decided to try to develop anti-metabolites in the same way as Farber, by making small changes in a metabolite needed by a cell to divide. With the help of George Hitchings and Gertrude Elion, two pharmaceutical chemists who were working at the Burroughs Wellcome Co. in Tuckahoe, many purine analogues were teste…
Vinca Alkaloids
The Eli Lilly natural products group found that alkaloids of the Madagascar periwinkle (Vinca rosea), originally discovered in a screen for anti-diabetic drugs, blocked proliferation of tumour cells. The antitumour effect of the vinca alkaloids (e.g. vincristine) was later shown to be due to their ability to inhibit microtubule polymerization alkaloys, and therefore cell division.
National Cancer Chemotherapy Service Center
The NCI, headed by Dr. John R. Heller Jr., lobbied the United States Congress for financial support for second-generation chemotherapy research. In response, Congress created a National Cancer Chemotherapy Service Center (NCCSC) at the NCI in 1955. This was the first federal programme to promote drug discovery for cancer – unlike now, most pharmaceutical companies were not yet interested in developing anticancer drugs. The NCCSC developed the methodologies and crucia…
Combination chemotherapy
In 1965, a major breakthrough in cancer therapy occurred. James F. Holland, Emil Freireich, and Emil Frei hypothesized that cancer chemotherapy should follow the strategy of antibiotic therapy for tuberculosis with combinations of drugs, each with a different mechanism of action. Cancer cells could conceivably mutate to become resistant to a single agent, but by using different drugs concurrently it would be more difficult for the tumor to develop resistance to the combination. H…
