Taking high amounts of zinc is LIKELY UNSAFE. High doses above the recommended amounts might cause fever, coughing, stomach pain, fatigue, and many other problems. Taking more than 100 mg of supplemental zinc daily or taking supplemental zinc for 10 or more years doubles the risk of developing prostate cancer.
How does zinc prevent cancer?
Zinc inhibits NF-kappa B via induction of A-20. Thus, zinc supplementation should have beneficial effects on cancer by decreasing angiogenesis and induction of inflammatory cytokines while increasing apoptosis in cancer cells.
Can you take zinc if you have breast cancer?
Some studies have shown that zinc can induce apoptosis in cancer cells and inhibit cell proliferation5. High levels of zinc supplementation had a positive effect on reducing oxidative stress and improving immune responses in cancer patients7.
Is it OK to take vitamin C and zinc together?
What drugs and food should I avoid while taking Vitamin C Plus Zinc (Multivitamins And Minerals)? Avoid taking more than one multivitamin product at the same time unless your doctor tells you to. Taking similar products together can result in an overdose or serious side effects.

Does zinc Fight Lung Cancer?
In general, zinc microenvironment may play a key role in oxidative stress, apoptosis, and/or cell signaling alterations which influence the behavior of malignant cancer cells , and this may play a role in preventing lung cancer.
Is zinc good for skin cancer?
There is evidence that zinc may favor the malignant transformation of normal cells: in tumor-bearing animals, supplemental Zn stimulated tumor growth and shortened life span; Zn is also a selenium (Se) antagonist and has been shown to abolish its anticarcinogenic effects (2,3).
Does zinc block radiation?
There is currently substantial clinical interest in zinc (Zn) as a protective agent against radiation-related normal tissue injury.
Can too much zinc cause breast cancer?
Zinc dyshomeostasis has been implicated in breast cancer as a modulator of oxidative stress, DNA damage response/repair pathways, and cell proliferation/apoptosis (52).
Can magnesium cause breast cancer?
We found that having a genetic tendency for higher blood levels of magnesium was linked to a higher risk of developing breast cancer. None of the other minerals and vitamins were associated with breast cancer risk.
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.
