How does prostate cancer radiation therapy work?
It uses a computer-driven machine that moves around the patient as it delivers radiation. Along with shaping the beams and aiming them at the prostate from several angles, the intensity (strength) of the beams can be adjusted to limit the doses of radiation reaching nearby normal tissues.
Why does radiation treatment for prostate cancer cause diarrhea?
Because the radiation beam passes through normal tissues, such as the rectum, bladder, and intestines on its way to the prostate, it kills some healthy cells. This is why diarrhea may result.
What are the late effects of radiation treatment for prostate cancer?
Some of the potential late effects of radiation to the prostate include: Most men will be sterile after radiation treatment for prostate cancer. Talk to your oncology team about sperm banking if you wish to have a child in the future. Erectile dysfunction or dry orgasm can occur after radiation therapy.
What is a radiation burn or rash?
A radiation"burn" or rash is a common side effect of radiation therapy for cancer. It’s also called radiation dermatitis. There’s no clear way to stop it from happening. But there’s a lot you can do to take care of your skinif you get one. Here’s what you need to know.
What is an APC of rectum?
Rectal bleeding caused by radiation proctitis is difficult to manage. Argon plasma coagulation (APC) is an electrocoagulation technique that appears to be an effective and low-cost alternative to the use of lasers in gastrointestinal endoscopy.
What is APC radiation proctitis?
APC is a safe, highly effective and long-lasting therapy in patients with rectal bleeding associated with radiation proctitis. It has been shown that several sessions of APC reduce the rate of bleeding and therefore the blood transfusion requirements. Moreover, the effect of treatment is long lasting.
What is the difference between proton therapy and radiation therapy for prostate cancer?
Traditional radiation delivers x-rays, or beams of photons, to the tumor and beyond it. This can damage nearby healthy tissues and can cause significant side effects. By contrast, proton therapy delivers a beam of proton particles that stops at the tumor, so it's less likely to damage nearby healthy tissues.
Does chronic radiation proctitis go away?
Radiation proctitis can begin during radiation treatment and last for a few months after treatment. Or it can occur years after treatment.
How is radiation proctitis diagnosed?
Radiation proctitis should be suspected in any patient who has had pelvic radiation exposure and presents with the symptoms mentioned above. The majority are diagnosed after colonoscopy or sigmoidoscopy with features demonstrating pallor, friability, and telangiectasias.
What is proctitis from radiation therapy?
Radiation proctitis is inflammation of the rectum that occurs as a result of acute damage to the rectum sustained from pelvic radiation.
Is Proton beam therapy better than radiotherapy?
It directs proton beams at cancer cells with precision. Proton therapy appears to be safer and more effective than conventional radiation therapy, because it can deliver a high dose to a very specific area, with minimal impact on surrounding tissues.

Patients with low to medium risk prostate cancer experienced a success rate of 99%, while those with high risk prostate cancer experienced a success rate of 76%.
Is proton therapy better than prostatectomy?
Protons are so precise that they were used successfully for decades at the Harvard cyclotron to treat skull base tumors, with excellent long-term outcomes. I've been told that the cure rate with proton therapy is less than one-half the cure rate with either radical prostatectomy (76%-80%) or ProstRcision® (83%).
Can you live with radiation proctitis?
One in five patients with acute radiation proctitis may require temporary cessation of therapy until the symptoms resolve. Fortunately, once the acute radiation proctitis has resolved, the majority of patients remain symptom-free and do not go on to develop chronic radiation proctitis.
Does radiation proctitis get better?
Can Radiation Proctitis be Treated or Healed? Yes, in most cases, we can provide some level of relief or treatment from radiation proctitis. The key is to come in as early as you notice symptoms.

These burns are common, but they tend to be mild and usually resolve within two months after radiation treatment ends.
How to protect skin from radiation?
Good skin care is one of the best defenses against radiation burns or other skin changes. Ask your doctor for recommendations on creams to keep the area as healthy as possible. Don’t rub or scratch the affected area, no matter how tempted. Scratching and rubbing only make the burn worse and slow the healing process.
How do you know if you have a radiation burn?
Radiation burn symptoms include: Other types of skin changes may occur as well. Your skin may become swollen and puffy, or have a “moist reaction” where it becomes wet, sore and prone to infection. Moist reactions usually occur around skinfolds, such as under the breasts.
What products can cause radiation burns?
Hair-removal products. Bubble bath products. Makeup. Some of these products may leave a coating on your skin that causes radiation burns or irritation, or makes them worse. Others may even affect the amount of radiation that enters your body, increasing your risk for side effects.
What to use on skin after radiation?
Run anything you want to use on your skin by your doctor, including shaving creams, gels and razors. Wear loose-fitting, soft clothes. You may further irritate burns if your clothing rubs against skin treated with radiation. Avoid tight-fitting clothes or items with elastic that may squeeze the treatment area.
How to get rid of burns on your face?
Scratching and rubbing only make the burn worse and slow the healing process. Shower or bathe with care. Use only mild soaps that your care team has approved. Shower or bathe with lukewarm water only. It’s OK to shower daily, but baths should be short and limited to every other day.
What type of radiation is used for prostate cancer?
The main types of radiation therapy used for prostate cancer are: External beam radiation. Brachytherapy (internal radiation) (Another type of radiation therapy, in which a medicine containing radiation is injected into the body, is described in Treating Prostate Cancer Spread to the Bone .)
What is the best treatment for prostate cancer?
Brachytherapy (internal radiation therapy) 1 Brachytherapy alone is generally used only in men with early-stage prostate cancer that is relatively slow growing (low-grade). 2 Brachytherapy combined with external radiation is sometimes an option for men who have a higher risk of the cancer growing outside the prostate.
How does proton beam therapy work?
Proton beam therapy focuses beams of protons instead of x-rays on the cancer. Unlike x-rays, which release energy both before and after they hit their target, protons cause little damage to tissues they pass through and release their energy only after traveling a certain distance. This means that proton beam radiation can, in theory, deliver more radiation to the prostate while doing less damage to nearby normal tissues. Proton beam radiation can be aimed with techniques similar to 3D-CRT and IMRT.
Why do you put a balloon between your prostate and your rectum?
Sometimes a balloon-like device or gel is put between the rectum and the prostate before treatment to act like a spacer to lessen the amount of radiation that reaches the rectum. Urinary problems: Radiation can irritate the bladder and lead to a condition called radiation cystitis.
What is EBRT radiation?
In EBRT, beams of radiation are focused on the prostate gland from a machine outside the body. This type of radiation can be used to try to cure earlier stage cancers, or to help relieve symptoms such as bone pain if the cancer has spread to a specific area of bone.

Some newer radiation machines have imaging scanners built into them. This advance, known as image guided radiation therapy (IGRT), lets the doctor take pictures of the prostate just before giving the radiation to make minor adjustments in aiming.
How long does radiation treatment last?
You will usually go for treatment 5 days a week in an outpatient center for at least several weeks, depending on why the radiation is being given. Each treatment is much like getting an x-ray. The radiation is stronger than that used for an x-ray, but the procedure typically is painless.
What are the different types of radiation treatments for prostate cancer?
What are the different types of radiation therapy for prostate cancer? Radiation treatments for prostate cancer can be divided into two main types: brachytherapy, or internal radiation, and external beam radiation. Brachytherapy can be further subdivided into low dose rate and high dose rate.

When it comes to early stages of disease, patients very frequently do well with either brachytherapy or external beam radiation. Success rates of around 90% or higher can be achieved with either approach.
Is rectal spacer gel biodegradable?
This leads to fewer side effects for the patient. The rectal spacer gel is biodegradable and after a few months dissolves on its own within the body, causing no harm or long-term effects. Back to top.
Is brachytherapy right for everyone?
It is also convenient for the patient as it is done in an outpatient setting and most people are able to get back to work the next day. But brachytherapy is not right for everyone. For some patients with less-aggressive disease, a watch-and-wait approach would also be very reasonable.
What is the treatment for prostate cancer?

How long does it take for radiation side effects to go away?
Side effects from radiation treatment are related to the area of the body being treated. Patients start to have side effects a few weeks into their treatment. While side effects may be unpleasant, there are treatments to help deal with them. Most side effects are temporary and slowly start to go away once treatment is done.
Why do people get second cancers?
These are called secondary cancers, and they happen because of the exposure of healthy tissue to radiation. Modern radiation techniques are designed to limit this exposure.

Can radiation cause side effects?
Radiation exposure can cause delayed side effects due to its gradual damage to healthy tissues. I recently read two reports concerning rectal problems that can show up weeks, even months, after radiation.
How long does it take for the prostate to shrink after radiation?
The prostate gland will end up having a lot of scar tissue. It will shrink in size to about half its original weight within a couple years after finishing radiation. The urethra (urine passage) passes through the canter of the prostate gland like the hole of a doughnut.
Can you have erections after radiation?
You can still usually have erections because the nerves and blood vessels that go to the penis are not as damaged as the prostate gland.
Is the prostate radiated?
The entire prostate gland is radiated when we treat the cancer. The prostate normally produces some of the fluid in the ejaculation . Radiation therapy has the side effect of damaging the glands in the prostate, so a lot less fluid is produced. The ejaculation may be dry or nearly dry.
How does radiation kill prostate cancer?
Radiation therapy is an effective treatment that kills prostate cancer cells by using high energy rays or particles. The radiation can be delivered in several ways, including brachytherapy (using seeds that are implanted in the patient’s body) and external beam radiation that projects the energy through the skin.

Slow cancer growth, reduce fracture risk. Be used as a palliative treatment to address pain from advanced cancer.
What is IGRT in prostate cancer?
IGRT refers to the use of daily imaging to check the tumor target’s position. Most often, this may include a low dose X-ray (kV) or CT scan (cone beam CT). For some patients, gold or platinum fiducial markers may be placed in the prostate before treatment. These markers show up on imaging scans and help the radiation oncologist see the tumor’s position, which helps prepare the patient for treatment each day.
What imaging is used to map prostate cancer?
Before treatment, your radiation team will use computerized tomography (CT) scans and magnetic resonance imaging (MRI) scans to map out the location of the prostate and tumor cells. During each treatment session, X-ray beams are focused on the targeted cancer areas. Oncologists can change the intensity of doses and radiation beams ...
What is radiation therapy for prostate?
This is a sophisticated form of external beam radiation, which is delivered by linear accelerators (LINACS). Oncologists can change the intensity and shape of the radiation beams to better target radiation delivered to the prostate while limiting radiation to nearby bladder and rectal tissue. Because of the treatment planning involved with this type of radiation therapy, the doctor can deliver far more precise, intense and effective doses of radiation with less risk of damaging surrounding tissue.
What is the benefit of proton therapy?
The main benefit of proton therapy is that, because of the beam’s physical properties, the beam stops at the borders of the tumor, preventing an “exit dose” that could affect nearby, healthy tissues in areas outside of the prostate target, such as the bladder and rectum. Current evidence suggests that it is equally effective as other radiation ...
Can SBRT be used for prostate cancer?
SBRT can offer some patients with localized prostate cancer the convenience of fewer treatments while maintaining treatment effectiveness and safety. SBRT may also be used to treat metastases for some patients to reduce tumor mass and potentially enhance survival.
