Alternative Cancer Treatment - Diet and Cancer

By: Meng Y

No sector of oncology is more confusing and controversial than the relationship between cancer and an individual's diet. Most people would like that think that there exists a diet which can make a significant impact on either the likelihood of cancer, or better yet aid in curing it once it is contracted.

All reputable sources are in agreement that no diet can cure cancer. There also is no evidence strong enough to support the idea that any diet in particular can prevent an individual from contracting it. However, there have been many studies conduct that strongly suggest that the occurrence, recurrence, and even one's survivability rate might be affected by the foods that they consume.

Though far from certain, many studies examined by researchers at Cornell University were able to correlate lower death rates - an increased five or ten year survivability, with certain dietary choices.

The Nurses Health Study which examined 1,982 women who had already developed breast cancer. These women were followed for an average of 13 years. Of those women 1200 had breast cancers that had not yet metastasized (spreading of a primary tumor to other areas of the body thus producing a secondary tumor of the same type). If an individual's cancer has spread then typically their survival rates are known to be much lower.

Some in the first group ate larger amounts of poultry and fish, containing protein and omega-3 fatty acids. They had significantly lower risk of death than women in the group who did not consume as much. Further, women who ate large amounts of hydrogenated oils had a significantly higher death rate.

Additionally, another study which was conducted by the National Cancer Institute observed 2,400 individuals. Of those individuals 975 women who had contracted breast cancer were asked to consume a low fat diet (33.3g per day) for a period of five years. Another 1,462 women consumed 51.3 g of fat per day. The group consuming less fat experienced a 42% reduction in the recurrence rate.

The draw back to all of these studies is that they merely observe observations, not causation. It is unclear from the data what is actually relevant and what isn't. Do these dietary choices only show that women who focus on keeping a healthy diet also make healthier lifestyle choices overall? Or do the foods that these women consume actually help or harm them and to what degree?

As with many studies involving fruits and vegetables, the answer is unclear. Apart from those which contain antioxidants, any beneficial effect is simply not known with confidence. In this case, however, the evidence is strong that foods high in antioxidants do help reduce the chances of contracting breast cancer.

Free radicals within one's blood stream are ionized atoms that are capable of harming cells. Antioxidants assist in ridding the body of these atoms. They combine with the free radicals causing them to be rendered harmless.

The studies on fat, however, are less clear. The leading theory says that since high estrogen levels are widely known to correlate with a greater risk of breast cancer and fat acts as an efficient storage of estrogen, then lowering fat therefore lowers the risk.

The flawed conclusion that is sometimes drawn however is the belief that eating fat makes you fat. But it isn't the consumption of fat that causes higher body fat, per se. Eating more calories than are used causes the body to store the excess in fat, leading to a higher body fat percentage. And, fat contains more calories per unit weight than other foods. The route is indirect.

Aside from the difficult to interpret or incomplete evidence, there is one thing that all experts mutually agree on: maintaining a healthy lifestyle and diet are always smart decisions. Whether these decisions lower the risk of contracting breast cancer or not, for the 1 in 12 women who will contract breast cancer at some point in their life, being in the most optimal health aids in combating the disease before, during and after.
