    This study suggests that vitamin D is associated with a reduced risk of breast cancer regardless of ER/PR status of the tumor. Future studies with a larger number of receptor-negative and mixed tumors are required.

Whole Health Source: Cancer and the Immune System - 0 views

  •  
    They found some important trends. Granulocytes from people over 50 years old had a reduced ability to kill cancer cells, as did granulocytes from people with cancer. This raises the possibility that cancer is not simply the result of getting too old, but a very specific weakening of the immune system.

    The most important finding, however, was that the granulocytes' kung-fu grip declined dramatically during the winter months. Here's Dr. Cui:

    Nobody seems to have any cancer-killing ability during the
    winter months from November to April.

    The role of vitamin D in cancer prevention.
    Garland CF, Garland FC, Gorham ED, Lipkin M, Newmark H, Mohr SB, Holick MF.
    Am J Public Health. 2006 Feb;96(2):252-61. Epub 2005 Dec 27. Review.
    PMID: 16380576
    DOI: 10.2105/AJPH.2004.045260

    Vitamin D status differs by latitude and race, with residents of the northeastern United States and individuals with more skin pigmentation being at increased risk of deficiency. A PubMed database search yielded 63 observational studies of vitamin D status in relation to cancer risk, including 30 of colon, 13 of breast, 26 of prostate, and 7 of ovarian cancer, and several that assessed the association of vitamin D receptor genotype with cancer risk.

    The majority of studies found a protective relationship between sufficient vitamin D status and lower risk of cancer. The evidence suggests that efforts to improve vitamin D status, for example by vitamin D supplementation, could reduce cancer incidence and mortality at low cost, with few or no adverse effects.

    Serum 25-hydroxyvitamin D and colon cancer: eight-year prospective study.
    Garland CF, Comstock GW, Garland FC, Helsing KJ, Shaw EK, Gorham ED.
    Lancet. 1989 Nov 18;2(8673):1176-8.
    PMID: 2572900

    Blood samples taken in 1974 in Washington County, Maryland, from 25 620 volunteers were used to investigate the relation of serum 25-hydroxyvitamin D (25-OHD) with subsequent risk of getting colon cancer. 34 cases of colon cancer diagnosed between August, 1975, and January, 1983, were matched to 67 controls by age, race, sex, and month blood was taken. Risk of colon cancer was reduced by 75% in the third quintile (27-32 ng/ml) and by 80% in the fourth quintile (33-41 ng/ml) of serum 25-OHD. Risk of getting colon cancer decreased three-fold in people with a serum 25-OHD concentration of 20 ng/ml or more. The results are consistent with a protective effect of serum 25-OHD on colon cancer.

    Dietary vitamin D and cancers of the oral cavity and esophagus.

    Ann Oncol. 2009 Sep;20(9):1576-81. Epub 2009 Jun 1.
    PMID: 19487490

    Conclusion: We observed inverse associations between dietary vitamin D intake and risk of SCCE and, perhaps, oral/pharyngeal cancer, which were most pronounced among heavy current smokers and heavy consumers of alcohol.

    Prospective study of predictors of vitamin D status and cancer incidence and mortality in men.
    Giovannucci E, Liu Y, Rimm EB, Hollis BW, Fuchs CS, Stampfer MJ, Willett WC.
    J Natl Cancer Inst. 2006 Apr 5;98(7):451-9.
    PMID: 16595781
    doi:10.1093/jnci/djj101

    Conclusions: Low levels of vitamin D may be associated with increased cancer incidence and mortality in men, particularly for digestive-system cancers. The vitamin D supplementation necessary to achieve a 25(OH)D increment of 25 nmol/L may be at least 1500 IU/day.

    The association of solar ultraviolet B (UVB) with reducing risk of cancer: multifactorial ecologic analysis of geographic variation in age-adjusted cancer mortality rates.
    Grant WB, Garland CF.
    Anticancer Res. 2006 Jul-Aug;26(4A):2687-99.
    PMID: 16886679

    CONCLUSION: These results provide additional support for the hypothesis that solar UVB, through photosynthesis of vitamin D, is inversely-associated with cancer mortality rates, and that various other cancer risk-modifying factors do not detract from this link. It is thought that sun avoidance practices after 1980, along with improved cancer treatment, led to reduced associations in the latter period. The results regarding solar UVB should be studied further with additional observational and intervention studies of vitamin D indices and cancer incidence, mortality and survival rates.

    Are sunlight deprivation and influenza epidemics associated with the onset of acute leukemia?
    Timonen T, Näyhä S, Koskela T, Pukkala E.
    Haematologica. 2007 Nov;92(11):1553-6.
    PMID: 18024404
    doi:10.3324/haematol.10799

    Month of diagnosis of 7,423 cases of acute leukemia (AL) in Finland during 1964-2003 were linked with data on influenza and solar radiation. Acute myeloblastic leukemia (AML) showed the highest risk in the dark season. During the light season, the incidence decreased by 58% (95% confidence interval, 16-79%) per 1,000 kJ/m2/d increase of solar radiation. Independent of solar radiation, AML increased by 9% (95% confidence interval, 0-19%) during influenza epidemics. Reoccurring at the same time annually, darkness-related vitamin D deficiency and influenza could cause successive and co-operative mutations leading to AL with a short latency.

    Vitamin D status and the risk of lung cancer: a cohort study in Finland.
    Kilkkinen A, Knekt P, Heliövaara M, Rissanen H, Marniemi J, Hakulinen T, Aromaa A.
    Cancer Epidemiol Biomarkers Prev. 2008 Nov;17(11):3274-8.
    PMID: 18990771v

    In conclusion, although there was no overall association between vitamin D and lung cancer risk, women and young participants with a higher level of vitamin D were observed to have a lower lung cancer risk. Although experimental data support the suppressing effect of vitamin D on the development of lung cancer, large epidemiologic studies from different populations with repeated measurements of vitamin D are warranted to confirm this finding.

New Research by D*action Member Dr. Cedric Garland Suggests Role Low Levels of Vitamin ... - 0 views

  •  
    San Diego, CA (PRWEB) May 25, 2009 -- Coming on the heels of the publishing in the Annals of Epidemiology of a new study led by Dr. Cedric Garland, on the preventive measures of vitamin D, GrassrootsHealth D*action Project is calling on physicians, health clinics and groups throughout the country to recognize the need for determining vitamin D levels and to ensure the public have their blood levels of vitamin D tested.

    According to research from the newly published study by Cedric F. Garland, Dr. P.H., FACE, Department of Family and Preventive Medicine and Moores Cancer Center of the University of California, San Diego (UCSD), "It is projected that raising the minimum year-around serum 25(OH)D level to 40-60 ng/ml (100-150 nmol/L) would prevent approximately 58,000 new cases of breast cancer and 49,000 new cases of colorectal cancer each year, and three quarters of deaths from these diseases, in the US and Canada."

Vitamin D Levels Linked to Breast-Cancer Prognosis - GrassrootsHealth | Vitamin D Action - 0 views

  •  
    Women who are vitamin D deficient when they are diagnosed with breast cancer are more likely to have their disease spread and are more likely to die than women who have adequate vitamin D levels, new Canadian research says.

    The study found that women who were vitamin D deficient were 94 per cent more likely to have their cancer metastasize (spread) and 73 per cent more likely to die.

    The research was led by Dr. Pamela Goodwin, a breast cancer researcher at Mount Sinai Hospital in Toronto. The study analyzed blood samples and disease outcome from more than 500 women diagnosed with breast cancer between 1989 and 1995. Women were followed up for an average of 11 years.
