Overview Cancer and vitamin D

---

Scores of studies show that Vitamin D prevents many cancers and treats a few cancers

• Prevention results from 2,000 to 5,000 IU of vitamin D
  Prevention really depends on the level of vitamin D in the blood, and some vitamin D-deficient groups need much more
• Treatment needs > 8,000 IU of vitamin D
  But must be careful, as vitamin D makes some Chemotherapy more potent

A high percentage of all cancer deaths are prevented by a high enough level of vitamin D in your bloodstream

Following graph from the CDC August 2010

CLICK HERE for Original study by Lappe - 2007
41 minutes good video of Lappe explaining the trial
in which she mentions the next 5-year trial underway with 2,000 IU of vitamin D
Breast Cancer details from the study
For years 2-4
Placebo: 8 Breast Cancers out of 266 women
1100 IU vitamin D + Calcium 4 Breast Cancers out of 403 women
That is 8/266 ==> 4/403 with vitamin D
So roughly 3% ==> 1% with 1100 IU of vitamin D
about a 3X reduction for Breast Cancer(vs 4X reduction for all Cancers)

Cancer Factoids from The Body, by Bill Bryson, 2019

• They (Cancers) have evolved to avoid detection,” says Vormoor. “They can hide from drugs. They can develop resistance. (VitaminDWiki also believes that many have also learned to hide.
• Something we have only recently realized is that before cancers metastasize, they are able to prepare the ground for an invasion in distant target organs, probably through some form of chemical signaling. “What this means,” Vormoor says, “is that when cancer cells spread to other organs, they don’t just turn up and hope for the best. They already have a base camp.
• Viruses and bacteria cause cancers, too. The World Health Organization 2011 estimated that 6 percent of cancers in the developed world but 22 percent in low- and middle-income countries are attributable to viruses alone.
• A significant fraction of childhood cancer deaths come not from the cancer itself but from the treatments for it.
