What to expect when having radiation therapy?
treatment are radiation therapy, radiotherapy, irradiation, and x-ray therapy. What is radiation therapy? Radiation therapy uses high-energy particles or waves, such as x-rays, gamma rays, electron beams, or protons, to destroy or damage cancer cells. Your cells normally grow and divide to form new cells. But cancer cells grow and divide faster than most normal cells. …
What is the success rate of radiation therapy?
Radiation Therapy (irradiation or radiotherapy) is the use of high energy radiation, primarily x-rays, to kill cancer cells. In high doses, radiation causes damage to cells by interfering with the cell’s ability to grow and reproduce. Cells that are growing and multiplying are very sensitive to the effects of radiation. Because cancer cells reproduce more frequently than normal cells, they …
At what stage of cancer is radiotherapy used?
Radiotherapy may be used in the early stages of cancer or after it has started to spread. It can be used to: try to cure the cancer completely (curative radiotherapy) make other treatments more effective – for example, it can be combined with chemotherapy or used before surgery (neo-adjuvant radiotherapy)

How does radiation help cancer?
When radiation is combined with surgery, it can be given: 1 Before surgery, to shrink the size of the cancer so it can be removed by surgery and be less likely to return. 2 During surgery, so that it goes straight to the cancer without passing through the skin. Radiation therapy used this way is called intraoperative radiation. With this technique, doctors can more easily protect nearby normal tissues from radiation. 3 After surgery to kill any cancer cells that remain.

If a person's cancer has returned (recurred), radiation might be used to treat the canceror to treat symptoms caused by advanced cancer.W hether radiation will be used afterrecurrence depends on many factors.For instance, if the cancer has come back in apart of the body that has already been treated with radiation, it might not be possible togive more radiation in the same place. It depends on the amount of radiation that wasused before.In other instances, radiation might be used in the same area of the body or
How does cancer spread?
Cancer can spread from where it started to other body parts. Doctors often assume thata few cancer cells might already have spread even when they can’t be seen on imagingscans like CT scans or MRIs. In some cases, the area where the cancer most oftenspreads to may be treated with radiation to kill any cancer cells before they grow intotumors. For instance, people with certain kinds of lung cancer may get radiation to thehead, even when there is no cancer known to be there, because their type of lungcancer often spreads to the brain. This is done to help prevent cancer from spreading tothe head even before it can. Sometimes, radiation to prevent future cancer can be givenat the same time that radiation is given to treat existing cancer, especially if the area thecancer might spread to is close to the tumor itself.
Can cancer be cured?
Sometimes cancer has spread too much to be cured. But some of these tumors can stillbe treated to make them smaller so that the person can feel better. Radiation might helprelieve problems like pain, trouble swallowing or breathing, or bowel blockages that canbe caused by advanced cancer3. This is called palliative radiation.

Why is radiation treatment important?
When radiation treatments are given for cancer, special care is taken to spare as much normal tissue as possible from radiation exposure. The radiation dose is carefully measured and aimed at the tumor to kill as many cancer cells with as little damage to normal tissue as possible.
What is the purpose of radiation therapy?
Radiation Therapy (irradiation or radiotherapy) is the use of high energy radiation, primarily x-rays, to kill cancer cells. In high doses, radiation causes damage to cells by interfering with the cell’s ability to grow and reproduce. Cells that are growing and multiplying are very sensitive to the effects of radiation.
When is radiation given?
When radiation is combined with surgery, the radiation treatments may be given before or after surgery. When it is done before surgery it is used to shrink the size of a tumor to make removal easier. More commonly the radiation treatments are given after surgery to reduce the chance that the cancer will come back, among other reasons.
Can radiation therapy be used for cancer?
Radiation is also used to treat some benign (non-cancerous) conditions. For some patients, radiation therapy will be the only treatment necessary for their cancer, but very often it is done along with surgery and/or chemotherapy.
What is external beam radiation?
external beam: an external beam radiation therapy machine outside your body aims the radiation at your cancer cells. internal or brachytherapy: Sometimes this type of radiation therapy is also called liquid radiation, because the radiation is placed inside your body, near the cancer cells. Most patients receive external beam radiation.
Why is the cell cycle important?
The cell cycle phase is important because usually radiation first kills the cells that areactively dividing. It doesn’t work very quickly on cells that are in the resting stage (G0) or are dividing less often. The amount and type of radiation that reaches the cell and thespeed of cell growth affect whether and how quickly the cell will die or be damaged. Theterm radiosensitivity describes how likely the cell is to be damaged by radiation.
What is radiation used for cancer?
Radiation used for cancer treatment is called ionizing radiation because it forms ions(electrically charged particles) in the cells of the tissues it passes through. It createsions by removing electrons from atoms and molecules. This can kill cells or changegenes so the cells stop growing.
How does radiation work?
To understand how radiation works as a cancer treatment, it helps to know the normallife cycle of a cell. The cell cycle has 5 phases, one of which is the actual splitting of thecell. When a cell splits, or divides, into 2 cells, it’s called mitosis. This 5-phase processis controlled by proteins known as cyclin-dependent kinases (CDKs). Because CDKsare so important to normal cell division, they too have a number of control mechanisms.
Where do radiopharmaceuticals go?
Radiopharmaceuticals are drugs that contain radioactive materials called radioisotopes.They may be put into a vein, taken by mouth, or placed in a body cavity. Depending onthe drug and how it’s given, these materials travel to various parts of the body to treatcancer or relieve its symptoms. They put out radiation, mostly in the form of alpha andbeta particles that target the affected areas. They’re most often used in small amountsfor imaging tests, but larger doses can be used to deliver radiation.
Can radiation be used to shrink cancer?
Some cancers are very sensitive to radiation. Radiation may be used by itself in thesecases to make the cancer shrink or disappear completely. Sometimes, a few cycles ofchemotherapy are given first. For other cancers, radiation may be used before surgery(as pre-operative or neoadjuvant therapy) to shrink the tumor, or after surgery to helpprevent the cancer from coming back (this is called adjuvant therapy).
Why is radiation considered a local treatment?
Most types of radiation are considered local treatments because the radiation is aimedat a specific area of the body (where there’s a tumor). Only cells in that area areaffected. Most forms of radiation therapy can’t reach all parts of the body, which meansthey’re not helpful in treating cancer that has spread to many distant areas.
What is 3D CRT?
This is an advanced form of external radiation therapy. As with 3D-CRT, computerprograms are used to precisely map the tumor in 3 dimensions. But along with aimingphoton beams from several directions, the intensity (strength) of the beams can beadjusted. This gives even more control over the dose, decreasing the radiation reachingsensitive normal tissues while delivering higher doses to the tumor.
