Calcium can bind secondary bile acids and ionized prevnetion acids, which can promote epithelial cell proliferation in the colon 6 — 8 ; calcium may also directly decrease epithelial cell proliferation 9. Results were similar when analysis was restricted to women without a change in milk intake over the past 10 years.

Calcium and cancer prevention -

In the D-Health trial, which included Australians 60 years and older, a monthly dose of 60, IU vitamin D for 5 years also did not reduce cancer mortality A meta-analysis of 21 randomized trials found no evidence that vitamin D supplementation was associated with reduced mortality from all causes combined or from cardiovascular disease Many participants in these trials had blood levels of vitamin D that are considered adequate for overall health.

This has led to speculation that any effects of vitamin D supplementation on cancer mortality might be more evident in people with low vitamin D levels 42 , and researchers are pursuing this question. Clinical trials are being conducted to examine the potential benefit of adding vitamin D supplements to other treatments for people with cancer.

For example, the phase 3 SOLARIS trial is testing whether adding high-dose vitamin D3 to chemotherapy and bevacizumab would extend the length of time patients with advanced or metastatic colorectal cancer live without their disease getting worse. Researchers are also studying vitamin D analogs —chemicals with structures similar to that of vitamin D—which may have the anticancer activity of vitamin D but not the toxic effects of high doses For example, ongoing clinical trials are testing both vitamin D and its analog paricalcitol alone or in combination with other treatments, including immunotherapy and chemotherapy, in patients with pancreatic cancer Black people are also less likely to use vitamin D supplements than White people Observational studies and investigations of biological mechanisms through which vitamin D status and supplementation influence cancer risk are ongoing.

Also under study is whether any beneficial effects of vitamin D on cancer outcomes may be restricted to people who have certain genetic variants in genes that metabolize or transport vitamin D 48 , For example, a recent analysis of a US population found improved cancer survival primarily among women and men with a specific form of a vitamin D binding protein called GC Home About Cancer Cancer Causes and Prevention Risk Factors Diet Vitamin D and Cancer.

Vitamin D and Cancer On This Page What is vitamin D? How much vitamin D do people need? Why are cancer researchers studying a possible connection between vitamin D and cancer?

Does vitamin D prevent cancer or lower the risk of dying from cancer? How is vitamin D being studied now in cancer research? What is vitamin D?

The Institute of Medicine IOM of the National Academies has developed the following recommended daily intakes of vitamin D, assuming minimal sun exposure 1 , 2 , which are the basis for the recommendations in the Dietary Guidelines for Americans, — : For those between 1 and 70 years of age, including women who are pregnant or lactating, the recommended dietary allowance RDA is 15 micrograms μg per day.

Because 1 μg is equivalent to 40 International Units IU , this RDA can also be expressed as IU per day. For those 71 years or older, the RDA is 20 μg per day IU per day.

For infants, the IOM could not determine an RDA due to a lack of data. Calcium has also demonstrated an inhibitory effect on experimental colon carcinogenesis. Mechanisms of calcium inhibition are still speculative, but the "calcium soaps" hypothesis, fatty acid destabilization of cellular membranes, modulation of protein kinase C and K-ras mutations are under investigation.

Additionally, numerous clinical studies of calcium modulation of human colonic hyperproliferation in high-risk groups as well as chemoprevention trials of calcium supplementation are currently ongoing.

Although the question of whether dietary calcium can prevent human colorectal cancer remains to be answered, the data presently available appear promising. Physical activity that is weight bearing is best, examples include walking, dancing, aerobics, skating and weight lifting.

Smoking is related to poor bone and general health. If you smoke, ask your doctor for assistance to stop smoking. Androgen Ablation, Osteoporosis and Prostate Cancer: GU Tumour Group Guidelines. Osteoporosis is a major health concern in men over 65 years of age and is currently underdiagnosed and undertreated.

Most men with prostate cancer are over 65 years of age. Androgen ablation therapy for prolonged periods is also a significant risk factor for inducing osteoporosis. Androgen ablation induced osteoporosis is a potential source of major morbidity, low QOL and mortality.

It is entirely treatable and can be stabilised or reversed. This group recommends that fracture incidence and BMD should be considered as part of any randomised trial involving prolonged androgen deprivation therapies.

This document does not address the possible relationship between high BMD in men and the risk of developing prostate cancer We do not attempt to address the potential use of bisphosphonates in the treatment and prevention of bone metastases 9 3 , as this is under review as a Priorities and Evaluation Committee proposal, submitted recently by Dr.

Many dietary factors Calicum been Cwlcium for their potential in the chemoprevention of ahd colorectal cancer.

Additionally, there have been Calciuum studies of calcium and cell proliferation in experimental animals. Supplemental calcium in the diet or drinking water has been reported to decrease the colonic epithelial hyperproliferation induced by bile and fatty acids, enteric resection, a nutritional stress diet, and to suppress induction of the tumor-promotion enzyme ornithine decarboxylase.

Calcium has also demonstrated an inhibitory effect on experimental colon carcinogenesis. Mechanisms of calcium inhibition are still speculative, but the "calcium soaps" hypothesis, fatty acid destabilization of cellular membranes, modulation of protein kinase C and K-ras mutations are under investigation.
