Thoughts on multivitamins containing selenium and prostate cancer?

I think most multi vitamins will NOT hurt you..I think where you can get in trouble is high dosing of certain vitamins and minerals ( and foods) ...Key Vitamins and Minerals to Avoid or Limit:
Vitamin E (Alpha-tocopherol): Daily doses greater than 400 IU are strongly discouraged, as they are associated with an increased risk of cancer progression.
Selenium: Studies indicate that high-dose selenium (e.g., 140 micrograms/day) can potentially increase the risk of dying from prostate cancer and has been linked to a 91% increase in high-grade cancer.
High-Dose Zinc: Long-term use of high-dose zinc supplements (often found in multivitamins) is associated with a higher risk of developing prostate cancer.
High-Dose Multivitamins: While regular, low-dose multivitamins may not be harmful, high-dose supplements should be avoided unless specified by a doctor.
Calcium: Excessively high total calcium intake (largely from supplements) has been linked with an increased risk of advanced prostate cancer.

It is generally recommended that men with prostate cancer avoid high-dose supplements unless they have a validated deficiency, as they offer no clear benefit and pose significant risks. Always consult with your oncologist before starting any supplement.

Last year, I was eating ALOT of high fat cottage cheese and honey which I love...and guess what, high fat dairy products should be avoided by older men because they are linked to prostate cancer progression...yep..and I ate ALOT thinking the calcium and ppprotein were good for me.

Sources (eg, web links) for your statements are important. In particular, the link regarding dairy products has been confirmed in some studies but not others. I'm continuing to drink milk to keep up the calcium intake, & my oncologist has no problem with that.

@readandlearn Key Findings on High-Fat Dairy and Prostate Cancer:
Disease Progression: Whole milk intake is specifically associated with a higher risk of developing fatal or lethal prostate cancer.
Recurrence Risk: Men who consume high-fat dairy after a prostate cancer diagnosis face a higher risk of recurrence and mortality.
Mechanism: Dairy products can increase insulin-like growth factor-1 (IGF-1), a hormone linked to cancer growth.
Amount Matters: The link between dairy and cancer is often associated with high consumption levels.
Alternatives: Low-fat and non-fat dairy options do not show the same consistent association with negative outcomes compared to high-fat options, though some studies suggest all dairy might carry risk.

my point was dont over do- I think I was eating far too much cottage cheese with honey- about 2-3 containers a week..and then late last May, I was diagnosed with prostate cancer...now I dont believe it was soley from my indulgence in high fat cottage cheese ( dont drink milk at all) but I was totally unaware of any link to prostate cancer- secondly, over the yrs, I was told not to worry about PC that I probably wouldnt get it and even if I did, "they dont even treat older men cause it is slow growing"..

2 of my primary care doctors in Houston told me that ( both women).

Brazil nuts are a good source of selenium.

Also AFAIK man is the only member of the animal kingdom where adult members consume milk.

Everything in moderation is better and most multivitamins do not have mega doses. Even then many vitamins get just get flushed from the body, but A, D, E, and K get stored and can build to toxic levels if taken daily at several hundred percent of recommended amounts. Same goes for many minerals. Recommended selenium is 55mcg per day and Centrum only has 21 mcg. Age has a stronger association with prostate cancer than environmental factors.

I take a zinc picolinate supplement 23mg twice a day. I haven't had foot odor in years. my feet don't sweat or stink. Even when they feel sweaty they are dry to the touch.

@xahnegrey40 There is still a lot they don’t know about dairy and its relationship to PCa.
Fat is a carrier for a variety of compounds - pesticides/insecticides are used on cows and can be absorbed into their bodies.
rBST is a growth inducing hormone which has been proven to enhance the growth of many cancer cells as well.
And what about what we don’t know? It’s a little misleading for ‘full fat dairy’ PERIOD! To be the reason for fatal PCa.
I guess the best you can do is drink truly organic milk sourced from a small operation which states its farming practices on the label. Unfortunately, not too many of these places are left since they are family run and the younger generation would rather play with their phones than get up before sunrise and tend to their business.

The dairy connection to prostate cancer hasn't been proven, but it has been proven that ADT and low testosterone can weaken bones. My endocrinologist recommended eating yogurt, lower fat milk, ice cream (in moderation) and other calcium sources for bone health rather than taking supplements, though she did put me on a Vitamin D supplement because my levels were marginal (normal, but barely).

So, I guess cheese is out. I think it's almost 100% dairy fat. And butter can't be far behind.
