Is zinc bad for breast cancer?
We observed that serum zinc level is associated with breast cancer risk in BRCA1 carriers and noncarriers. Analysis of serum zinc concentration revealed tendency to increased risk of breast cancer for unselected breast cancers and BRCA1 carriers with zinc level <750±50 μg/L.
What vitamins should you take if you have breast cancer?
A recent study found that breast cancer patients who took antioxidants during chemotherapy had a higher risk of breast cancer coming back. Antioxidants include vitamin A, vitamin C, vitamin E, carotenoids, and Coenzyme Q10.

What supplements should breast cancer patients avoid?
Patients who took antioxidants, including vitamins A, C, and E as well as carotenoids and coenzyme Q10, both before and during chemotherapy were more likely to have a recurrence.

How much vitamin D should a breast cancer patient take?
In general, for bone health, most clinicians recommend a level of 15 to 20 ng/ml or higher. Because one study did show a higher rate of cancer recurrence in breast cancer patients who had vitamin D levels below 29 ng/ml, a target level of 30 ng/ml might be a good idea for people who have had breast cancer.
What foods should breast cancer survivors avoid?

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.
Does zinc block radiation?
There is currently substantial clinical interest in zinc (Zn) as a protective agent against radiation-related normal tissue injury.
