Although the accuracy of colonoscopy for colon cancer is very high, yet the cost is very expensive and has a high risk of side effects. The Annals study pointed out that, for the patients with low risks, it is unnecessary for them to receive repeated colonoscopies on condition that the result of the first colonoscopy is negative. Although some experts strongly suggest that men and women aged 50-75 should receive routine screening for colorectal cancer, yet it does not mean that they should receive screening one after one.

But the procedure is a little complex. The patients should clean the the bowels with a combination of a liquid diet and laxatives before the exam. During the process of examination, the patients have to suffer a lot form the test for that the doctors will insert a long tube into the rectum and into the large intestine. Certainly, there are some side effects and complications, such as perforated bowel or diverticultisis.

Generally speaking, the elder are still at a high risk of cancer. However, the benefits of screening do not outweigh the risks from the long term. And the researchers hope that newer, non-invasive screening procedures in coming years. Besides, tow studies published earlier this year indicates that patients are much more likely to get colorectal cancer screening when the tests involve only a stool sample rather than an invasive colonoscopy.

As we all know, most patients with cancer suffer a lot from serious side effects of chemotherapy, including nausea, vomiting, and poor appetite. In that case, they usually can not intake enough nutrients and their quality of life will decrease correspondingly. Therefore, it is necessary for us to get familiar with some nutrition tips during the chemotherapy, which can make a great different in helping you stay healthy and comfortable. Then, we will talk about it in detail in the following part.

Drinking more water

Diarrhea and vomiting can contribute to excessive loss of fluid and dehydration finally develops. Some common symptoms of dehydration may include dry mouth, sunken eyes and low urine dehydration. Therefore, in order to avoid dehydration, the patients with colon cancer should drink more water during the course of treatment.

Fight against constipation

On account of the patients’ special individual condition, some patients with colon cancer suffer from constipation during the chemotherapy. On one hand, the patients can drink more water so that the food can be easily digested. On other hand, they should keep a diet rich in fiber which can promote peristalsis of intestine and further alleviate the symptom of constipation. Further more, the patients can stimulate the digestion of the intestine through doing some physical exercise, such as take a 20-minute walk.

Make food tastier

Most patients are not willing to intake any food. However, for patients, diet plays an important role in the prognosis. Therefore, the consumption of food is absolutely substantial for them to better fight against colon cancer during the course of treatment. They can add some spices to the food or try drinking flavored mineral water instead of water.

Try to avoid alcohol

During chemotherapy, the patients should be kind to the liver for that the liver can metabolize the potential toxins of the chemical drugs in the bloodstream so that the patients suffer less from the side effects of chemotherapy. Apart from that, alcohol can also worsen the gastrointestinal symptoms. Consequently, the patients should try their best to get rid of alcohol as far as possible. The patients can also intake some traditional Chinese medicine which can protect the liver.

According the results of some studies, the development of colorectal cancer is closely related with dietary habits. Therefore, some researchers pointed out that changes in dietary habits can lower one’s risk of colorectal cancer to some extend. Then, we will discuss how to prevent the development of colorectal cancer through changing your eating habits in detail in the following part.

1.    Change from an animal-based diet to a plant-based diet

Previously, some investigators find that vegetarians and Seventh Day Adventists have a lower risk of colorectal cancer for that plants have less fat, more fiber and more phytonutrients. On account of the anticancer properties, the plants can reduce the growth of cancer cells. Therefore, we should intake more plant-based foods rather than animal-based foods.

2.    Maintain a diet low in total fat and saturated fat

On the basis of some studies about the association between fat and the development of colorectal cancer, low density lipoprotein can promote the growth of cancer cells. On the other hand, excessive consumption of fat can stimulate the excretion of bile, which may stagnate the large intestine for a long period of time. Then, it will be turned into apcholic acid that is a kind of carcinogenic substance. Therefore, in order to better prevent the development of colorectal cancer, we should eat less food rich in total fat and saturated fat.

3.    In crease the consumption of fiber

More and more studies confirm that a high fiber diet is associated with lower chances of colorectal cancer for that fiber can move the potential carcinogenic substances through the intestine faster and decrease the contact time between carcinogens and the intestinal wall. As a result, you had better try to keep a diet high in fiber, such as wheat bran, kidney beans, garbanzo beans, navy beans, whole wheat, whole grains, legumes, whole grain bread, prunes and so on.

4.    Drink less alcohol

Alcohol consumption can slightly increases the risk of colorectal cancer and beer is closely related with the development of colon cancer for that nitrosamines- a kind of carcinogen can be activated in the intestines. Therefore, we should try our best to get rid of heavy drinking in daily life.

As we all know, the incidence of cancer is on a rapid rise in recent years and millions of people die from cancer annually. Certainly, rectal cancer is also included. It is well known that the development of kidney cancer is attributed to many relevant factors, including dietary habits, genetic factor, and environmental factor and so on. Therefore, in order to better prevent the development of kidney cancer, people should get familiar with some key points in daily life. In the following part, we will illustrate them in detail as far as possible.

Eat more fruits and vegetables

With the improvement of living level, people ten to consume more fish and meat. As a result, they usually consume less fruit and vegetable that play an important role in improving people’s immunity. You should try to add more fruits and vegetables to your diet in daily life for that a variety of fruits and vegetables helps ensure that you're getting all the nutrients you need.
