What is radiation therapy?
Along with surgery and chemotherapy, radiation therapy has long been a mainstay of cancer treatment. It uses high-energy waves or particles such as x-rays, gamma rays, electrons, or protons to destroy or damage tumor cells.
How does radiation affect cancer cells?
Radiation creates small breaks within the DNA of cancer cells, preventing the cells from growing and dividing, and often causing them to die. Radiation therapy uses high-enegery waves or particles to destroy or damage tumor cells. Because cancer cells divide rapidly, they’re more likely to succumb to DNA damage, ...
How is cancer treated?
Some cancers are treated with internal radiation therapy, in which radioactive material, sealed in a container, is implanted next to or inside a tumor. High doses of internal radiation therapy are given by placing a powerful source of radioactivity in the body for a few minutes at a time.
Can you stay in the hospital after a temporary implant?
Patients who receive temporary implants often stay in the hospital while the implant is in place and may have limitations on visitors. Their bodily fluids are not radioactive. Once the implant is removed, their body is radiation-free.
Does radiation damage DNA?
Because cancer cells divide rapidly, they’re more likely to succumb to DNA damage, but radiation can damage DNA in normal cells as well. The damage that radiation therapy does to normal cells may lead to a variety of side effects, which generally improve over time.

Can radiation therapy cause side effects?
They may occur with radiation therapy because the high doses of radiation that are used to kill cancer cells can also damage healthy cells in the treatment area. Side effects are different for each person. Some people have many side effects. Others have hardly any. Side effects may be more severe if you also receive chemotherapy before, during, or after your radiation therapy.
How long does it take for prostate cancer to shrink?
The median time for a prostate cancer to shrink is about 18 months (some quicker, some slower).
What is the term for the death of cancer cells?
The first point to be made here is that, with the exception of spermatozoa and lymphocytes (among the two most rapidly dividing cells in the body), cancer cells die what is called a mitotic death. This means that the cell dies when it attempts to divide.
What happens after radiation treatment?
What happens after treatment finishes? After radiation therapy has finished, your treatment team will give you general information about your recovery. They will tell you how to look after the treatment area and recommend ways to manage side effects. They will also suggest who to call if you have any concerns.
How long does it take for cancer to go away after radiation?
Radiation therapy usually does not have an immediate effect, and it could take days, weeks or months to see any change in the cancer. The cancer cells may then keep dying for weeks or months after the end of treatment.
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.
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.
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.
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.
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.
What is internal radiation therapy?
With this method, sources of radiation are put into or near the area that needstreatment. The radiation only travels a short distance, so there’s less risk of damagingnearby normal tissues. Brachytherapy can be used to deliver a high dose of radiation to
How long does radiation side effects last?

What is the best treatment for radiation?
One way to reduce side effects is by using radioprotective drugs, but these are only used for certain types of radiation given to certain parts of the body. These drugs are given before radiation treatment to protect certain normal tissues in the treatment area. The one most commonly used today is amifostine. This drug may be used in people with head and neck cancer to reduce the mouth problems caused by radiation therapy.
What are the side effects of brachytherapy?
If your treatment includes brachytherapy (internal radiation implants), you might notice breast tenderness, tightness, redness, and bruising. You may also have some of the same side effects that happen with external radiation treatment.
How long does it take for radiation to cause side effects?
Late side effects can take months or even years to develop. They can occur in any normal tissue in the body that has received radiation. The risk of late side effects depends on the area treated as well as the radiation dose that was used. Careful treatment planning can help avoid serious long-term side effects.
Can radiation therapy cause low blood count?
Rarely, radiation therapy can cause changes in your blood count levels. These blood cells help your body fight infection and prevent bleeding. If your blood tests show low blood counts, your treatment might be stopped for a week or so to allow your blood counts to return to normal. This side effect is more likely if you’re also getting chemotherapy.
