Cancer is the third biggest cause of death in the world according to study. Death rate would increase faster because of cancers. Unless caught in the early stages, cancers are very difficult to treat. Usually people do not like to mention cancers. The main treatment approach we can get is just surgery . But in fact when you really have a cancer and cancer cells have spreaded in your body , surgery is not so effective as you expected.

Prevention is much wiser way than surgery. You know that there are a lot of cancer which can be preventable. A panel of experts collected the statistics after reviewing the available scientific evidence about cancer, diet and exercise. While they also work out some guidelines about how we can lower cancer rates.

Actually we do not know exactly the relationship of lifestyle and cancers. But very few cancers can be inherited. So by modifying our lifestyle will reduce the chances of cancer by at least a third.

First, obesity is the major cause of cancer. It is cause of cancers of the oesophagus, colon and rectum, pancreas, breast, endometrium, and kidneys. The mass index of our body is supposed to lie between 21 and 23. So we need a weight loss diet to shed those kilos with exercise and caloric restriction.

Secondly, do some exercise. Apart from losing weight, being fit has direct anti-cancer effect. Moderate physical exercise for 30 minutes like brisk walking a day is recommended by researchers. It is fit for most of us. The another important point of doing exercises is persistence. You would get nothing with exercises for only one or two days

Next, our dietary intake also has very close relationship with cancer. Mostly we have to care about is how much alcohol we need drink. Certain alcohol is beneficial to our health but excess will increases the risk for cancers of the mouth, pharynx, larynx, oesophagus, colon and rectum, and breast as well as cirrhosis and liver cancer. Men shouldn't drink more than two standard drinks of alcohol a day while women no more than one a day.

Else we need to eat less and eat mostly foods of plant origin instead of red meat and processed meat. To cut down meat intake is helpful to the environment and meat production has taken a large amounts of agricultural land and water.
