Can cancer be prevented?

There is no guaranteed way to prevent cancer from developing, but there are some things we can do to reduce the risk of it happening. The most obvious thing to do is to avoid all known carcinogens. For example, cigarette smoke is a known carcinogen, so it makes sense to avoid it as far as possible. Likewise, charred barbecued meat is another known carcinogen, so cutting down on it would be helpful.

But there are probably many carcinogens that we simply don't know about yet. It is also possible that cancer may develop when the body lacks certain nutrients (vitamins, minerals, phytochemicals etc), or simply because of chemical imbalances in the body. We simply don't know for sure. But scientists can make educated guesses as to what might reduce the risk of cancer by studying what a group of people eat and seeing how their health progresses as they get older. Such studies are known as epidemiological studies, and they rely on large groups of people to report on their activities, diets and health over many years.

For example, large scale studies have observed that a statistically significant number of people who eat lots of fruits and vegetables, and less red meat, have lower rates of colon cancer. This is why we hear recommendations to eat less red meat in order to prevent colon cancer. It is not because medical science knows how chemicals in red meat trigger colon cells to become cancerous. Naturally, the accuracy of these dietary recommendations rests heavily on how well these epidemiological studies were conducted in the first place. For example, did the participants accurately report what they ate? were there other factors that could have accounted for the difference in cancer rates which the study might have missed - e.g. perhaps the fruit eaters were mostly nurses who are generally more health conscious?

Cancer may also be more likely as we age, simply because our immune systems become weaker and because the cells in our body will have undergone much more duplication (mitosis) over the years. The combination of weaker immunity and the greater chance of errors in cellular division may make cancer an inevitable consequence of old age.

Cancer patients may wonder if there was something they could have done to prevent their cancer from happening, but it is usually difficult to pinpoint the cause of a patient's cancer. The only exceptions when the patient has come into contact with known carcinogens repeatedly, such as cigarette smoke, asbestos fibers, or excessive radiation.
