Fish Oil for Cancer Prevention and Nutrition

Cancer is one of the leading killers in the human population today. The most common forms of cancer are lung cancer, which takes the lives of hundreds of thousands of Americans per year, as well as breast cancer and colon cancer.    

What are the causes of cancer, and what happens to the body when it is afflicted with cancer?    

As it is already known, the body is composed of millions of cells. Each cell can divide and grow, to replace cells that are old or damaged. When cancer occurs, cells divide in an unregulated manner, causing an overgrowth called a tumor.    

A tumor serves no beneficial function in the body.    

In fact, tumors compete for the supply of oxygen and nutrients that healthy cells need. Cancer can happen because of agents in the environment, called carcinogens. Some of these are cigarette smoke, alcohol, illegal drugs, and other forms of pollution in the air, land, and water.     

Nutrition and prevention of cancer can be possible, as all it takes is a little change in diet and activity.    

Moderate regular exercise should be done. Nutritionists and medical professionals recommend going organic when it comes to diet. Organic in a sense means that the vegetables and meat products are farmed without the use of herbicides and pesticides.    

It is also recommended to eat fruits and vegetables that are rich in antioxidants such as tomatoes, cherries, squash, bell peppers, and blueberries. For protein sources, eating lean meat should be an option instead of red meat. Less fat is found on them.    

Nutritionists also recommend tofu and fish as sources of protein. Fish, especially halibut, mackerel, sardines, albacore tuna, and salmon are rich sources of omega-3 fatty acids.    

Omega-3 fatty acids are currently being examined by researchers as part of nutrition and prevention of cancer.    

As an example, the University of Maryland Medical Center (UMMC) advices taking 1 teaspoon of fish oil per day, as a means of preventing inflammation and the risk of breast cancer. This translates to about 1 to 2 capsules of fish oil supplements per day. For the prevention of colorectal cancer, the UMMC advices 1 to 3 tablespoonfuls of fish oil per day.    

According to a 2003 publication for the journal Indoor and Built Environment, the omega-3 fatty acids such as docosohexenoic acid (DHA) and eicosapentenoic acid (EPA), which are found in many food sources such as fish oil, can make cancer patients more receptive to the medications of chemotherapy.

In 2006, a team from the University of Texas published their work in the Proceedings of the American Association for Cancer Research. It has been established that the omega-3 fatty acid EPA, found in fish oil, can prevent tumor growth.    

Their aim was to determine if mice with lung cancer tumors will have positive health manifestations if fed with fish oil. Their results showed that fish oil alters the formation of prostaglandins, which in turn can suppress the growth of tumors. At present, more studies are being done to establish the link between fish oil with nutrition and prevention of cancer.
