While the data is inconclusive, people concerned about developing brain cancer may want to reduce their exposure to potential contributing factors, such as regular cell phone use and consumption of aspartame (a synthetic sweetener sold under the brand names NutraSweet and Equal, and is added to many sugar-free foods and beverages). Preliminary reports have indicated that pesticide exposure may increase the risk of brain tumors, but these reports are inconclusive. There have also been reports of higher incidences of brain tumors in children with high exposure to electromagnetic fields (EMFs), for example those who live near high-voltage power lines. However, more recent research rules out the link between electromagnetic fields and childhood brain cancer.
A whole food diet that minimizes processed foods and artificial ingredients is recommended. Eating organic foods will support overall health and can provide food-based nutrients that will support apoptosis of brain cancer cells. Aside from data showing a possible link between pesticides and brain tumors, as well as between aspartame and brain cancer, no conclusive associations have been found between diet and brain tumors. For now, avoiding pesticides and aspartame by maintaining an organic, whole food diet appears to be the best dietary advice.
Some herbs and nutrients show promise as potential complementary treatments for brain cancer, including:
- Curcumin: Several cell studies have found that curcumin significantly suppressed the invasion of glioma and other brain cancer cells in vitro
- Dong Quai: Early research on this herb commonly used in traditional Chinese medicine shows promise for the treatment of primary brain tumors. Research in Taiwan showed that Dong Quai had anticancer effects on glioblastoma cells.
- Ginseng: A recent report in the International Journal of Cancer indicates that a component in Panax ginseng (which researchers call Compound K) may help control the growth and invasiveness of brain tumors.
- Green tea: Canadian researchers discovered that epigallocatechin gallate (EGCG), an active ingredient in green tea, may help stop the progression of glioma cells in vitro.
- Phosphatidylserine and ginkgo biloba: Other supplements to consider for primary brain tumors include phosphatidylserine and ginkgo biloba, which are known to improve brain function. These nutrients can reduce treatment-related side effects such as cognitive dysfunction and memory loss. Additionally, they may exert some preventative effects by stimulating apoptosis and reducing genetic damage to brain cells.
