Radiation

I had radiation for a different cancer and it was easy and painless which I hadn't understood ahead of treatment. I wore biofilm to avoid radiation burns on the skin, so I was able to run every day. With prostate cancer it can be important to have a space or placed so that you avoid radiation burns to the rectum, which can bleed for along time after. And usually this radiation effect is in the rectum and can cause sensitive digestion. Radiation can damage your bone marrow which negatively affects bone density. For these and other reasons I favor the 5 fraction MRI guided treatment. I keep posting this link which I think is the best on the subject of radiation treatment. I can also recommend the doctor in the video. https://www.youtube.com/watch?v=aWCqAQ2SEn0
Radiation, I forgot to mention can make you tired. Radiation damages healthy cells in addition to healthy ones. It can cause mild anemia, increased cortisol levels and drain metabolic energy. Bless your struggle with luck.

There are different types of radiation.

I’ve had 7+ weeks of IMRT savage radiation. Had no side effects at all. Had it in the morning first thing, went to work right after for a full day. About five years later, I started having incontinence problems, but that could be due to the prostatectomy. I had eight years prior.

I’ve also had three sessions of SBRT radiation to zap a metastasis on my spine. Again, no side effects at all.

Side effects from radiation can vary from
Fatigue
Radiation proctitis
Rectal issues
Rectal bleeding
Bladder infection
Breaks in bones radiation damage to bones
Fibroses in bladder reduce capacity

In general, toxicities after postprostatectomy radiation using photon-based techniques have been tolerable, although the rates of late grade 2 and gastrointestinal (GI) and genitourinary (GU) toxicities range from 10% to 20% with image-guided intensity-modulated radiation therapy (IMRT).

What this means. “ late grade 2 and gastrointestinal (GI) and genitourinary (GU) toxicities”
Above describes moderate symptoms of damage to the bowel and bladder, requiring minimal intervention but impacting daily activities, and occurring after salvage radiotherapy for a recurrence or persistent cancer after initial treatment. Gastrointestinal (GI) symptoms can include moderate diarrhea or bleeding, while genitourinary (GU) symptoms might involve increased urinary frequency, pain, or intermittent bleeding.
