Vitamin D deficiency and effects on cancer

I had an appointment with my oncologist on Tuesday, and the one thing of note, besides the fact my numbers were essentially unchanged, was she made mention of the benefits discovered in cancer progression by increasing Vitamin D levels.

She researched other patients of hers, and discovered they were essentially all Vitamin D deficient, and recommended taking a Vitamin D supplement (1000 IU per day).

Considering the constant reinforcement [hype] by the dermatology lobby, and sun screen manufacturers, of the hazards of extended exposure to sunlight, the major source of Vitamin D, and me being the uber cynicist I am, I find that fact very believable.

She also knows I'm not much into taking supplements, plus I do get a lot of unprotected sun exposure when I ride my bike, but she put it out there for me to at least investigate.

So I did some research on the subject, and came across this very interesting article on the benefits of Vitamin D, performed at the Mayo Clinic, in newly diagnosed Diffuse Large B Cell Lymphoma (DLBCL) patients.

Of course it was only one study, a relatively small sample, and it wasn't even performed on Mantle Cell Lymphoma patients, so how much benefit it will be to me or others is still open to question. Heck, I'm not even sure I'm Vitamin D deficient (that will be checked next month), but none the less, the data is compelling, and IMO worth further consideration, if not for me, then at least others.

So even if you don't like taking supplements [like myself], at least have your Vitamin D levels checked, and consider spending more time outside exposed to the sun, without using any sun block. If nothing else, at least it will get you out of the house, and doing something a little more beneficial than simply sitting around the house reading some blog. :)

Who knows, they may even discover it's just one more benefit to exercising outside, beyond the obvious.

Getting your Vit D "checked" is easy if you have health insurance that will cover it (I don't). I think there are enough studies for various ailments (specifically coronary artery disease) that it's reasonable for everyone to take a Vit D supplement. (safer than sun exposure).

I take 2000 units/day. The only downside is possible hypercalcemia. A serum Calcium is a lot cheaper than a serum Vit D level.

Why is hypercalcimia a problem? Do you just absorb more of the natural calcium through the food we eat? That only seems like a problem if you were taking a calcium supplement as well.

And are you taking Vitamin D or D3, and is there a difference? I have only seen D3 available.

I just had blood work done and my doctor told me the same thing. He wants me to take 2000 units of Vitamin D a day. I have started yet.

My in-laws were told the same thing. Is there some new test or something?
Marc said…
No, I just think doctors and others are starting to realize, we're spending far too much time in the house [on computers], and not spending enough time outside [living] getting enough sunlight.

You'd be better off spending more time in the sun.
The skin produces approximately 10,000 IU vitamin D in response [to] 20–30 minutes [of] summer sun exposure—50 times more than the US government's recommendation of 200 IU per day!

And I am iron deficient, big time.

Folate and B12 levels were also within the normal range. The only problem now is determining what is causing the iron deficiency, which in the case of men, is [very] rare. My oncologist has given me a Globin Fecal test to perform, and has scheduled me for a consultation with a colorectal surgeon to discuss performing a colonoscopy, which could be problematic because of my large spleen. In the mean time, I've decided to start taking an iron supplement, it's only the quantity that is causing me some consternation. I've been told by a very knowledgeable person that to overcome an iron deficiency, I need to be taking 300 mg o...

This is just one of those days

It's one of those days you just want to sit around the house and do absolutely nothing, or watch some movies you have recorded. It might even be a good day to read a book, if you were so inclined, which I am not. As you should be able to see from the view out my bedroom window, it is raining outside. The rain started last night, and hasn't let up since. I can't complain too much though, as this is the rainy season, and we do need the rain. Plus Monday's are typically my day off from exercise, so I will surprise everyone, and not complain. I just feel sorry for anyone who might be visiting from, say Argentina, like a friend of mine (fellow MCLer), who happens to be in Cambria today. He might be a little disappointed. Fortunately the rest of the week, when he will be in LA, will be nice, and the real intent of his trip was to visit his son in Tahoe, who works at one of the ski resorts, and ski, so I know he's not complaining too much either. This weather will actually...

When is enough, enough?

Today I learned, Lance Armstrong, the most drug tested athlete in the history of sport, is being accused of doping, again . This time by the US Anti Doping Agency (USADA), who claim they have collected blood samples from him in 2009 and 2010 that were “fully consistent with blood manipulation including EPO use and/or blood transfusions.” Really! What took them so long? The French have been trying to make allegations of drug doping stick for years, ever since he won his first Tour d'France, but to no avail. And now the USADA claims to have evidence to support that claim, and they've waited almost 3 years before releasing this evidence. Needless to say, I am skeptical. Then there's this from the Congressional Budget Office (CBO): Increasing the federal excise tax on cigarettes by 50 cents per pack eventually would increase Medicare and Social Security spending, slightly. Eventually? What is the CBO suggesting here? That we should encourage smoking, because if we don't, in...
