Is sun exposure dangerous when you have prostate cancer?

Posted by denis76 @denis76, Jan 15 2:18pm

Since my diagnosis, I've been trying to avoid sun exposure. My doctor said it's dangerous to travel to the southern regions.

Is it true that sun exposure can negatively impact the disease? Vitamin D is used to synthesize testosterone, is that the issue?

Who travels to the southern regions?

I know that -

I am saying that even though those man have natural protection from UV radiation they have heighten risk of getting PC which negates UV effect on possibly INITIATING formation of PC , which was what doctor possibly insinuated.

@surftohealth88 But we see this a lot, don’t we? Sickle cell anemia and thalassemia (mediterranean form) prevent malaria in most cases. One genetic defect can be a bonus when it comes to another disease - can’t win’em all, right?😉

Once I ended my course of ADT, I began having skin problems: acne, folliculitis, and much greater photosensitivity. I have olive skin, and the sun was never a problem. I’d tan lightly, and if I got a light burn, it turned to tan. Now I have to cover up completely or I get nasty blotches that turn to long-lasting skin damage. I don’t know if there’s correlation, much less causation here, but I have to wonder if this hasn’t been caused by the return of testosterone in my body, skin damage caused by two years of prednisone, or just plain aging. Whatever it is, it’s a bummer, because I enjoy being outside, and now I have to cover up for all my favorite activities.

@surftohealth88 They’re still looking into those “why’s.”
> Why a higher rate in blacks?
> Why a higher rate in Ashkenazi Jews?
> Why a lower rate in Asians?

It’s complicated.

Yes , mostly genetics and than we have influence of diet and lifestyle and environmental factors as is the case for other cancers and other diseases , but we digress from original question ; ). The original question was :

Does sunshine exposure cause PC ?

I think that it would be the best if @denis76 asks his doctor - it would be very interesting to hear doctor's reasoning .

I haven’t heard this either. My RO actually prescribed me vitamin D so I wouldn’t think that would be the issue

@shmo You have to remember that 4 nutrients ADEK are fat-soluble so they can build up in your system to toxic levels. The others are water-soluble so any excess passes through your kidneys out in your urine. Just check with your doctor or pharmacist to be safe. I personally have always been "solar-phobic" although I do sunbathe cautiously for health and a tan!

For what it’s worth. About 8 months after my PC, I was diagnosed with skin cancer on my thigh(she said it was a very unusual area). It was caught very early. I asked her if there was any correlation between the two, and she said most likely no, that my skin cancer was an accumulation of years in the sun(I was 72 at the time of removal). Heck, when we were young we’d put oil on our skin and bake in the sun! Of course, she recommended “covering up” whenever outside. I wear SPF 40 and 50 Nike long sleeve shirts and hats regularly. When we go to baseball games, we always get tickets in the shade. I’ve been given a clean bill of health but requested 6 month checkups for peace of mind. Hope this is helpful. Best wishes.

I live in Jacksonville Florida and grew up in south Florida.

I am dealing now with skin cancers from the constant sun burns I have every weekend.

I have heard nothing about PC and sun. I too have been taking Vitamin D as with all the sun screens I take now reading my need Vitamin D supplements. I have vitamin D on my supplement list at Mayo and no one has mentioned it being a problem just don't take too much.

Are you light skinned? Maybe trying to help you not have to deal with another type cancer associated with sun damage and UV rays. I am Italian and tan very dark but still have ongoing SCC and BCC skin cancers. But I did it to myself with probably hundreds of time being really badly sunburned 30-40 years ago.

I did not start using sun block until about 20 years ago but the damage to my skin was already done.
