Will lung cancer occur? What is the cause?

People who know about lung cancer know that there are many causes of lung cancer. It is not just smoking as we think. An unreasonable diet can also lead to lung cancer, so we need to pay attention. So what is the cause of lung cancer? Let's find out together!

What is the cause of lung cancer?

1. High-fat diet

First of all, we need to pay attention to the fact that if our diet is high in fat, then we may develop lung cancer. The current consensus is that a high-fat diet can promote the occurrence of colon cancer and breast cancer. Howe et al.'s study first discovered that a high-fat diet is highly correlated with the occurrence of breast cancer. Case-control studies in recent years also believe that the intake of total dietary fat and saturated fatty acids can increase the relative risk of colon cancer and rectal cancer. The possible mechanism is that a large amount of fat intake can promote the secretion of bile acid into the intestine, thereby affecting the composition of intestinal microbial flora, stimulating the production of secondary bile acids and promoting the occurrence of colon cancer.

2. High cholesterol diet

Foods high in cholesterol can also increase the risk of lung cancer, so we should pay attention to our diet. Epidemiological studies have found that dietary cholesterol can increase the risk of lung cancer and bladder cancer. In addition, a case-control dietary survey conducted abroad also found that after adjusting for total calories, alcohol consumption and smoking, dietary cholesterol can significantly increase the risk of pancreatic cancer.

3. High energy and high carbohydrates

In addition, the occurrence of lung cancer may also be related to our high energy intake. We need to pay attention to the fact that it is generally believed that excessive calorie intake will increase body fat, and adipose tissue provides an endogenous site for estrogen synthesis, thereby increasing the risk of breast cancer and endometrial cancer. High-carbohydrate and low-protein foods are risk factors for gastric cancer. The explanation for this research result is that this kind of diet has a weak buffering capacity for gastric acid, which reduces the pH in the stomach and increases the synthesis of nitrosamines and nitrosamine amides in gastric juice.

4. Certain special eating habits

There is a large amount of epidemiological data and animal experimental evidence that shows that eating pickled, fermented and grilled foods is closely related to the occurrence of cancer, because these foods contain a large number of mutagens and carcinogens. The incidence of gastric cancer in people who like to eat high-salt foods is significantly increased, because sodium chloride has been proven to promote cancer.

What are the causes of lung cancer? In fact, there are many other reasons that can lead to the occurrence of lung cancer. Today, the editor only introduces the causes of lung cancer from the perspective of diet. If we want to better prevent lung cancer, we also need to actively understand other causes. I wish you a happy life.
