What Can One Do to Reduce the Chances of Getting Cancer (6)

To reduce the chances of getting cancer, additional general actions are worthy of consideration: (1) Improve the diet and living environment, (2) Improve the physical status, (3) Improve the mental status, and (4) Follow nature’s rules.

Improve Your Diet and Living Environment

Although anything we eat needs to go through the gastrointestinal track and will be digested before being absorbed and utilized by the body, it is probably true that we are what we eat.  It is not surprising that eating too much fatty food tend to make people fat.  Many reports showed that people on high-fat and low-fiber diet tend to have a high probability of getting colon cancer.  It is well known that fruits and vegetables contain a lot of phytochemicals which are associated with antioxidant and anticancer activities.  It is also not surprising that air pollution and smoking tend to increase the chances for people to get lung cancer. 

Improve Your Physical Status

Do regular exercise to keep your body in good shape.  A physically healthy body means all body components are functioning in coordination according to nature’s rules.  If this is the case, there will be a lower probability for normal cells to be accidentally changed into cancer cells.

According to a scientific article published by British Journal of Sports Medicine in 2009, men with leisure-time physical activity of more than 5.2 METs (metabolic equivalents) had a lower risk of cancer death as compared with man whose mean intensity of physical activity was less than 3.7 METs (lowest quartile).

Improve Your Mental Status

Emotion and health are very closely related.  Mental status affects cytokines (down-regulation or up-regulation) which are related to many health issues.  In our daily lives, we are often under all kinds of emotion.  The bad news is that it has been reported that negative emotions are associated with poorer health.  However, the good news is that positive emotions are associated with good health.  One specific example is that positive emotions lower elevated levels of inflammatory cytokines, such as interleukin 6 (IL-6).

Although there is no solid evidence showing that stress is directly related to the occurrence of cancer, many studies did show that stress can produce a micro-environment that is more favorable to cancer growth.

Follow Nature’s Rules

What parameters are important in complying with the rules of nature?  These include circadian rhythm, nutrition, air, water, temperature, exercise, chemicals, viruses, bacteria, and other environmental factors.  Examples will be presented in the upcoming sections.

Lycopene

Lycopene belongs to the carotenoid family.  It is a red pigment and photochemical that blocks free radicals; it is found in tomato, papaya, watermelon, and some other fruits/vegetables.

It was reported that lycopene is a promising agent for prostate cancer chemoprevention based on the studies from animal and human clinical trials. Preclinical studies show that lycopene has potent in vitro and in vivo antitumor effects, suggesting potential preventive and therapeutic roles for the compound.  Some studies showed that dietary intake of lycopene is inversely associated with the risk of many cancers.  However, clinical trials with lycopene have only recently been started, and available clinical data have not shown a firm conclusion with regard to its use in cancer prevention and treatment.

Avocados

Avocados are native to Mexico and have been cultivated in tropical and Mediterranean climates throughout the world.  They are available in almost all grocery stores.

Avocado is a high fat food, but the majority of the fat comes from oleic acid; this is one of the reasons that avocados can lower blood levels of bad cholesterol and triglyceride. In addition to fat, vitamins, minerals, and fiber, avocados are rich in phytochemicals, which may reduce the risk of some chronic diseases, such as arthritis.  Some people believe eating avocados may have some cancer prevention effect.
