Do you ever recover from radiation?
Radiation not only kills or slows the growth of cancer cells, it can also affect nearby healthy cells. The healthy cells almost always recover after treatment is over. But sometimes people may have side effects that are severe or do not get better.
Does radiation shorten your life?
"Rapidly dividing cells, such as cancer cells, are more affected by radiation therapy than normal cells. The body may respond to this damage with fibrosis or scarring, though this is generally a mild process and typically does not cause any long-term problems that substantially affect quality of life."
What can I expect after my first radiation treatment?
The most common early side effects are fatigue (feeling tired) and skin changes. Other early side effects usually are related to the area being treated, such as hair loss and mouth problems when radiation treatment is given to this area.

What type of radiation is used to treat cancer?
Another factor that affects the radiation dose to the heart is what type of radiation is used. There are several radiation types you may have heard about including the most common form, known as "photon" radiation, which uses X-rays to treat your cancer. Additional forms of radiation treatment for cancer may include "proton" or "electron" radiation These forms of radiation have different properties that can be used in an attempt to limit the dose of radiation to your heart.
How to reduce radiation dose?
Another way of reducing the radiation dose to normal tissue is the use of tools to decrease motion of organs when breathing in and out. For example, if a person has lung cancer, the tumor in the lung will move up and down when the person inhales and exhales. A belt can be applied over the patient's midsection to help the patient decrease big breaths that result in greater motion. A special type of CT scan is done that can watch the tumor's movement and account for this breathing in treatment planning. Another technique includes a process called "gating." This treats only the tumor during certain times in the patient's breathing cycle. All of these efforts attempt to decrease the amount of radiation to normal tissue.
What is the radiation field?
Radiation oncologists attempt to limit the area of tissue treated with radiation (called the radiation field) without decreasing needed treatment of the cancer. The risk of developing heart toxicities after radiation is associated with the amount and areas of the heart within the radiation field. Even if the heart is not targeted in your treatment, there may be some overlap of radiation to the heart depending on where your cancer is located.
What is the name of the medicine that affects the heart?
Certain types of chemotherapy affect the heart, including the class of medicines called "anthracyclines" (i.e. daunorubicin, doxorubicin, epirubicin, and idarubicin) and anthracycline-like medicines (i.e. mitoxantrone). When combined with radiation that may involve the heart, there is an increased potential for heart damage, heart failure and side effects.
What is restenosis?
Patients who have a blocked artery in the heart have a stent placed to open the blockage. These stents (called drug-coated stents) have a medication on the stent to limit scar tissue that grows inside the stent.
Treatment of restenosis
The most common treatment of restenosis is placement of another drug-coated stent inside the old stent, since this usually works better than balloon alone. If a patient develops restenosis after two or more layers of stents, radiation treatment (brachytherapy) is an excellent option for preventing another recurrence of blockage due to scar tissue.
How does brachytherapy work?
Unlike the way radiation is used to destroy cancer cells, brachytherapy inside the artery does not destroy cells in the scar tissue that narrows the artery.
How is coronary brachytherapy given?
First, the interventional cardiologist opens the scar tissue as much as possible with a balloon (angioplasty). Next a thin ribbon is advanced inside the artery to deliver radiation to the vessel wall. After three to five minutes, the radiation is withdrawn and the procedure is completed. Adding another stent is possible, but usually not necessary.
What to expect after coronary brachytherapy?
There is no pain associated with brachytherapy. The recovery after brachytherapy is like a heart catheterization. You will need a few days to rest and limit physical activity.
How effective is coronary brachytherapy?
Brachytherapy greatly reduces the chance of recurrent blockages and need for repeat heart catheterization procedures.
Is coronary brachytherapy right for you?
The decision to perform coronary brachytherapy will be made by your primary cardiologist and must be customized to each patient. For patients with multiple episodes of restenosis we believe this is an excellent treatment option.
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 happens if you get radiation treatment?
After a few weeks, your skin might become dry, flaky, or itchy, or it may peel. This is sometimes called radiation dermatitis.
How long does radiation side effects last?
Remember that the type of radiation side effects you might have depends on the prescribed dose and schedule. Most side effects go away within a few months of ending treatment. Some side effects may continue after treatment ends because it takes time for the healthy cells to recover from radiation. Side effects might limit your ability ...
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.
How long does it take for brain tumors to show up?
Side effects depend on where the radiation is aimed. Some side effects might show up quickly, but others might not show up until 1 to 2 years after treatment.
