How does vitamin D help cancer?
In studies of cancer cells and of tumors in mice, vitamin D has been found to have several activities that might slow or prevent the development of cancer, including promoting cellular differentiation, decreasing cancer cell growth, stimulating cell death (apoptosis), and reducing tumor blood vessel formation ( …
How much vitamin D should a cancer patient take?

Which vitamin D is best for cancer patients?
Vitamin D may decrease tumor invasiveness and propensity to metastasize, leading to reduced cancer mortality. Higher serum 25-hydroxyvitamin D (25[OH]D) levels at diagnosis have been linked to longer survival in cancer patients.
Is there a strong relationship between vitamin D deficiency and cancer?
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.
