Results of a Prostate Cancer/Vitamin D Trial: Effectiveness Safety Recommendations
Radiation therapy uses Prostatatumor Tablette rays or particles to kill cancer cells. Depending on the stage of the prostate cancer and other factors, radiation therapy might be used:.
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. In EBRTbeams 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.
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. Each treatment lasts only a few minutes, although the setup time — getting Prostatatumor Tablette into place for treatment — takes longer.
Newer EBRT techniques focus the radiation more precisely on the tumor. This lets doctors give higher doses of radiation to the tumor while reducing Prostatatumor Tablette radiation exposure to nearby healthy tissues.
Radiation beams are then shaped and aimed at the prostate from several directions, which makes it less likely to damage surrounding normal tissues and organs. It uses a Prostatatumor Tablette 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 Prostatatumor Tablette the Prostatatumor Tablette can be adjusted to limit the doses of radiation reaching nearby normal tissues. This lets doctors deliver an even higher Prostatatumor Tablette dose to the cancer.
Some newer radiation machines have imaging scanners built into them. This appears to help deliver the radiation even more precisely and results in fewer side effects. It uses a machine that delivers radiation quickly as it rotates once around the body. This allows each Prostatatumor Tablette to be given over just a few minutes. This technique uses advanced image guided techniques Prostatatumor Tablette deliver large doses of radiation to a precise area, such as the prostate.
Because there are large doses of radiation in each dose, the entire course of treatment is given over just a few days. The side effects, though, are not better. Proton beam therapy focuses beams of Prostatatumor Tablette instead of x-rays on the cancer. Unlike x-rays, which release energy Prostatatumor Tablette 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 Prostatatumor Tablette prostate while doing less damage to nearby normal tissues. Prostatatumor Tablette in theory proton beam therapy might be more effective than using x-rays, so far studies have not shown if this is true. Right now, proton beam therapy is not widely available.
Proton beam radiation might not be covered by all insurance companies Prostatatumor Tablette this Prostatatumor Tablette. Some of the side effects from EBRT are the same as those from surgerywhile others are different. Bowel problems: Radiation can irritate the rectum and cause a condition called radiation proctitis. This can lead to diarrheasometimes with blood in the stool, and rectal leakage.
Most Prostatatumor Tablette these problems go away over time, but in rare cases normal bowel function does not return. To help lessen bowel problems, you may be told to follow a special diet during radiation therapy to help limit bowel movement during treatment. Sometimes a balloon-like device is put in the rectum during each treatment to keep the bowel as still as possible while treatment is given.
Urinary problems: Radiation can irritate the bladder and lead to a condition called radiation cystitis. Urinary problems usually improve over time, but Prostatatumor Tablette some Prostatatumor Tablette they never go away.
As described in Prostatatumor Tablette surgery section, there are different levels and types of incontinence. Overall, this side effect occurs less often with radiation therapy than after surgery.
The risk is low at first, but it goes up each year for several years after treatment. Rarely, the tube that carries urine from Prostatatumor Tablette bladder out of the body the urethra may Prostatatumor Tablette very narrow or even close off, which is known as a urethral stricture.
This might require further treatment to open it up again. Erection problems, including impotence: After a few years, the impotence rate after radiation is about the same as that after surgery. Problems with erections usually do Prostatatumor Tablette occur right after radiation therapy but slowly develop over time. This is different from surgery, where impotence occurs immediately and may get better over time. As with surgery, the older you are, the more likely it is you will have problems Prostatatumor Tablette erections.

Prostatatumor Tablette Lymph nodes normally provide a way for fluid to return to the heart from all areas of the body. If the lymph nodes around the prostate are damaged by radiation, fluid can collect in the legs or genital region over time, causing swelling and pain. Lymphedema can usually be treated with physical therapy, although it may not go away completely.
See lymphedema to learn more. These pellets are placed directly into your prostate. The use of brachytherapy is also limited by some other factors. For men who have had a transurethral resection of the prostate TURP or for those who already have urinary problems, the risk of urinary side effects may be higher. Brachytherapy might not work as well in men with large prostate glands because it might not be possible to place the seeds into all of the correct locations.
One way to get around this may be to get a few months of hormone therapy beforehand to shrink the prostate. Imaging tests such as transrectal ultrasoundCT scansor Prostatatumor Tablette are used to help guide the placement of the radioactive pellets.
Special computer programs calculate Prostatatumor Tablette exact dose of radiation needed. There are 2 types of prostate brachytherapy. Both are done in an operating room. You will get either spinal anesthesia where the lower half of your body is numbed or general anesthesia where you are asleepand you might Prostatatumor Tablette to stay in the hospital overnight. Either brachytherapy treatment can be used alone or combined with external beam radiation given at a lower dose than if used by itself.
In this type, pellets seeds of radioactive material such as iodine or palladium are placed inside thin needles, which are inserted through the skin in the area between the scrotum and anus and into the prostate.
The pellets are left in place as the needles are removed and give off low doses Prostatatumor Tablette radiation for weeks or months. Radiation from the seeds travels a very short distance, so the seeds can give off a Prostatatumor Tablette amount Prostatatumor Tablette radiation in a very small area.
This limits the amount of damage to nearby healthy tissues. Usually, around seeds are placed, but this depends on the size of the Prostatatumor Tablette. Because the seeds are so small, they seldom cause discomfort, and are simply left in place after their radioactive material is used up.
You may also get external beam Prostatatumor Tablette along with brachytherapy, especially if there is a higher risk that your cancer has spread outside the prostate for example, if you have a higher Gleason score. This Prostatatumor Tablette is done less often.
It leaves higher doses of radiation in place for a short time. Hollow needles are Prostatatumor Tablette through the skin between the scrotum and anus and into the prostate. Prostatatumor Tablette nylon tubes catheters are placed in these needles.
The needles are then removed but the catheters stay in place. Radioactive iridium or cesium is then placed in the catheters, usually for 5 to 15 minutes. Generally, about 1 to 4 brief treatments are given over 2 days, and the radioactive substance is removed each time. After the last treatment the catheters are removed. For about a week after treatment, you may have some pain or swelling in the area between your scrotum and rectum, and your urine may be reddish-brown.
Radiation precautions: If you get permanent LDR brachytherapy, the seeds will give off small amounts of radiation for several Prostatatumor Tablette or months. There's also a small Prostatatumor Tablette that some of the seeds might move migrate. You may be asked to strain your urine for the Prostatatumor Tablette week or so to catch any seeds that might come Prostatatumor Tablette.
You may be asked to take other precautions as well, such as wearing a condom during sex. Be Prostatatumor Tablette to follow any instructions your doctor gives you. There have also been reports of the seeds moving through the bloodstream to other parts of the body, such as the lungs. Bowel problems: Brachytherapy can sometimes irritate the rectum and cause Prostatatumor Tablette condition called radiation proctitis.
Urinary problems: Severe urinary incontinence trouble controlling urine is not a common side effect. But some Prostatatumor Tablette have problems with frequent urination or other symptoms due to irritation of the urethra, the tube that drains urine from the bladder. This tends to Prostatatumor Tablette worse in the weeks after treatment and gets better over time. Rarely, the urethra may actually close off known as a urethral stricture and need to be opened with a Prostatatumor Tablette or surgery.
Erection problems: Some studies have found rates of erection problems to Prostatatumor Tablette lower after brachytherapy, but other studies have found that the rates were no different than with external beam radiation or surgery. The younger you are and the better your sexual function before treatment, the more likely you will be to regain function after treatment.
