Side effects of brachytherapy can include swelling, bruising, bleeding, or pain and discomfort at the spot where the radiation was delivered. Brachytherapy used for gynecologic cancers or prostate cancer can lead to short-term urinary symptoms, including incontinence or pain on urination.

How long are you radioactive after brachytherapy?

No radiation remains in your body after temporary brachytherapy, so there is no risk to others. Some LDR, PDR and HDR treatments require one or more days in the hospital and may cause discomfort. This may be due to the catheters or applicators and having to stay relatively still for a prolonged period.

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.”

Are you put to sleep for brachytherapy?

The implant procedure is usually done in a hospital operating room designed to keep the radiation inside the room. You’ll get anesthesia, which may be either general (where drugs are used to put you into a deep sleep so that you don’t feel pain) or local (where part of your body is numbed).

What is a Gleason score of 7?

A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer. Doctors look at the Gleason score in addition to stage to help plan treatment.

What is the success rate of HDR brachytherapy?

Has a minimized risk of side effects, due to the targeted and precise nature of delivering the radiotherapy from inside the body. Is a minimally invasive technique i.e. it doesn’t involve extensive surgery.

What are the disadvantages of brachytherapy?

You need a general or a spinal anaesthetic. With radioactive seeds, you need to avoid close contact with children or pregnant women for a couple of months after treatment. Bladder side effects may be more severe than with external beam radiotherapy.

How long has brachytherapy been around?

In the first demonstration of brachytherapy in 1911, French physician Octave Pasteau used a urethral catheter containing radium. The technique evolved, and by the 1980s, a version known as low-dose-rate (LDR) brachytherapy, which is still in use today, had emerged.

How safe are radiowaves?

Are there any safety limits on human exposure to radio waves? Yes. Most national authorities have adopted international science-based safety guidelines specifying radio wave exposure limits. The limits have been set with wide margins to provide protection from established adverse effects on health.

How long does it take to fully recover from radiation therapy?

Most side effects generally go away within a few weeks to 2 months of finishing treatment. But some side effects may continue after treatment is over because it takes time for healthy cells to recover from the effects of radiation therapy. Late side effects can happen months or years after treatment.
