when was radiation used in cancer treatment

Full Answer

How long does it take to recover from radiation treatment?

The general effects of radiation therapy like fatigue, nausea, and headaches resolve fairly quickly after treatment. Your body just needs time to process the radiation but can recover within a few weeks. Delayed side effects of radiation therapy, on the other hand, may require further treatment to alleviate.

How is radiation therapy used to treat cancer?

• Before surgery (to reduce the size of a tumor/usually combined with chemotherapy)
• After surgery (to clean up any cancer cells that may remain after surgery/usually combined with chemotherapy)
• As a primary treatment (with or without chemotherapy) to slow the growth of a tumor
• To treat metastases

The first attempted x-ray treatment was by Victor Despeignes, a French physician who used them on a patient with stomach cancer. In 1896, he published a paper with the results: a week-long treatment was followed by a diminution of pain and reduction in the size of the tumor, though the case was ultimately fatal.

Which is worse radiation or chemo?

The radiation beams change the DNA makeup of the tumor, causing it to shrink or die. This type of cancer treatment has fewer side effects than chemotherapy since it only targets one area of the body.

What's the difference between chemo and radiation?

Chemotherapy and radiation therapy are both treatments for cancer – the uncontrolled growth and spread of cells to surrounding tissues. Chemotherapy, or “chemo,” uses special drugs to shrink or kill cancer cells. Radiation therapy, or “radiation,” kills these cells with high-energy beams such as X-rays or protons.

But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.

How is radiation given?

Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.

This is done to help prevent cancer from spreading to the head even before it can.

How does cancer spread?

Cancer can spread from where it started to other body parts. Doctors often assume that a few cancer cells might already have spread even when they can’t be seen on imaging scans like CT scans or MRIs. In some cases, the area where the cancer most often spreads to may be treated with radiation to kill any cancer cells before they grow into tumors. For instance, people with certain kinds of lung cancer may get radiation to the head, even when there is no cancer known to be there, because their type of lung cancer often spreads to the brain. This is done to help prevent cancer from spreading to the head even before it can. Sometimes, radiation to prevent future cancer can be given at the same time that radiation is given to treat existing cancer, especially if the area the cancer might spread to is close to the tumor itself.

How is radiation delivered to cancer?

External beam radiation therapies are delivered through a specialized machine directly to the cancer site. These include the following types of radiation therapy: Proton therapy uses a beam of protons to deliver radiation directly to the tumor. A proton beam conforms to the shape and depth of a tumor while sparing healthy tissues and organs.

What are the different types of radiation therapy?

Three common types of internal radiation therapy include: 1 Brachytherapy involves radioactive material that is implanted in the body. Dozens of tiny “seeds” containing radioactive iodine are placed at the tumor site with a special needle or catheter. This is done as an outpatient procedure. Brachytherapy is used for treatment of prostate, cervical, endometrial, vaginal and breast cancers. 2 Intraoperative radiation therapy (IORT) is used to treat an exposed tumor during cancer surgery. IORT delivers a high dose of radiation to a surgically exposed treatment area. Surrounding healthy organs and tissues are protected by lead shields. This type of radiation can be used for certain gastrointestinal cancers and other cancers that are challenging to remove during surgery. 3 Stereotactic radiosurgery (SRS) is not actually surgery. Instead, it uses dozens of tiny radiation beams to treat tumors in the head and neck with a single radiation dose. MD Anderson uses the Gamma Knife® SRS system. Gamma Knife is used to treat cancer that has spread to the brain or head or neck area, as well as tumors in the base of the skull, malignant gliomas, acoustic neuromas, pituitary tumors and meningiomas.

What is the subspecialty of oncology concerned with radiation therapy?

The subspecialty of oncology concerned with radiotherapy is called radiation oncologist . Radiation therapy is commonly applied to the cancerous tumor because of its ability to control cell growth. Ionizing radiation works by damaging the DNA of cancerous tissue leading to cellular death.

What is radiation oncology?

Radiation oncology is the medical specialty concerned with prescribing radiation, and is distinct from radiology, the use of radiation in medical imaging and diagnosis. Radiation may be prescribed by a radiation oncologist with intent to cure ("curative") or for adjuvant therapy.

How does radiation therapy work?

Radiation therapy works by damaging the DNA of cancerous cells. This DNA damage is caused by one of two types of energy, photon or charged particle. This damage is either direct or indirect ionization of the atoms which make up the DNA chain. Indirect ionization happens as a result of the ionization of water, forming free radicals, notably hydroxyl radicals, which then damage the DNA.

How much radiation does hair loss occur?

Epilation (hair loss) may occur on any hair bearing skin with doses above 1 Gy. It only occurs within the radiation field/s. Hair loss may be permanent with a single dose of 10 Gy, but if the dose is fractionated permanent hair loss may not occur until dose exceeds 45 Gy.

When was radiation first used?

The history of radiation therapy or radiotherapy can be traced back to experiments made soon after the discovery of X-rays (1895) , when it was shown that exposure to radiation produced cutaneous burns. Influenced by electrotherapy and escharotics — the medical application of caustic substances — doctors began using radiation to treat growths and lesions produced by diseases such as lupus, basal cell carcinoma, and epithelioma. Radiation was generally believed to have bactericidal properties, so when radium was discovered, in addition to treatments similar to those used with x-rays, it was also used as an additive to medical treatments for diseases such as tuberculosis where there were resistant bacilli.

Why did doctors use radiation?

Influenced by electrotherapy and escharotics — the medical application of caustic substances — doctors began using radiation to treat growths and lesions produced by diseases such as lupus, basal cell carcinoma, and epithelioma.

What was the first treatment for tuberculosis?

After using radium in the surgical treatment of tuberculosis, researchers including Béla Augustin and A. de Szendeffy soon developed a treatment using radioactive methyholated iodine, which was patented under the name dioradin (formed from "iodine and radium") in 1911. Application of this treatment was referred to as iodo-radium therapy, and involved injecting dioradin intramuscularly. It seemed promising to the developers, because in several cases, fever and hemoptysis had disappeared. Inhalation of iodine alone had been an experimental treatment for tuberculosis in France between 1830 and 1870.

Why is radium used in bath salts?

The radium commonly used in bath salts, waters, and muds was in low-grade preparations, due to the expense, and their usefulness in curative solutions was questioned, since it had been agreed upon by physicians that radium could only be used successfully in high doses. It was believed that even radiation emanation at higher doses than were useful would cause no harm, because the radioactive deposits were found to have been absorbed and released in urine and waste within a period of three hours.

What are the advantages of radium xrays?

The most marked effects produced with radium therapy were with lupus, ulcerous growths, and keloid, particularly because they could be applied more specifically to tissues than with x-rays. Radium was generally to be preferred when a localized reaction was desired, while for x-rays when a large area needed to be treated. Radium was also believed to be bactericidal, while x-rays were not. Because they could not be applied locally, x-rays were also found to have worse cosmetic effects than radium when treating malignancies. In certain cases, a combination of x-ray and radium therapy was suggested. In many skin diseases, the ulcers would be treated with radium and the surrounding areas with x-rays so it would positively affect the lymphatic systems.

What is radium used for?

Radiation was generally believed to have bactericidal properties, so when radium was discovered, in addition to treatments similar to those used with x-rays, it was also used as an additive to medical treatments for diseases such as tuberculosis where there were resistant bacilli.
