Cancer prevention and treatment need to be vigilant against three "killers"

According to data released by the National Cancer Center in 2022, among the 4.064 million new cancer patients in China, the number of lung cancer cases is 828,000, and among the 2.414 million people who died of cancer, 657,000 suffered from lung cancer. Whether it is new cases or deaths, lung cancer is at the forefront.

In recent years, with the continuous improvement of the health literacy level of the Chinese population and the popularization of lung cancer screening programs, patients with pulmonary nodules are more common. Many people are worried that lung nodules are a precursor to lung cancer?

According to the location of the lesion, lung cancer can be divided into central lung cancer and peripheral lung cancer. Lung nodules do not equal lung cancer. The first chest CT reveals small nodules in the lungs, most of which are benign. Therefore, patients do not need to panic excessively and should be reviewed regularly.

In general, the probability of malignancy of the two major types of nodules is relatively high, one is a solid nodule greater than 8mm, and there are burrs, lobes or pleural traction signs around the nodules; The other type is mixed-density nodules, which have both ground-glass components and solid components and are greater than 50%, and there are thickened blood vessels inside.

It is recommended that lung cancer screening be carried out once a year for high-risk groups over 40 years old, with a family history of lung cancer and smoking, or a history of environmental and high-risk occupational exposure, and chronic obstructive pulmonary disease.

The incidence of pancreatic cancer is rising, how can it be prevented?

Pancreatic cancer is one of the most malignant cancers, because it has no obvious symptoms in the early stage, and most of them are already advanced when detected. The incidence and mortality of pancreatic cancer have increased, and it is a malignant tumor with poor prognosis. Since there are no obvious clinical symptoms, early screening, early detection, early treatment, and timely identification of lesion "signals" are important means to improve the survival rate of pancreatic cancer. If you wait until the body has bad symptoms to go for examination, the cancer may be difficult to control.

Many symptoms of pancreatic cancer may appear at an early stage, and the most obvious characteristics of patients are emaciation and fatigue. In addition, jaundice throughout the body may also be associated with pancreatic cancer.

At present, the cause of pancreatic cancer is not clear, but it has been determined that pancreatic cancer is related to chronic pancreatitis, carcinogen nitrite, etc.

To prevent pancreatic cancer, we must first control the predisposing factors and adjust the dietary structure. Pickled foods, smoked foods, and leftovers all contain nitrite, try to avoid eating, increase the intake of fresh vegetables and fruits, adhere to physical exercise, and avoid excessive obesity.

How to pay attention to digestive system tumors that eat out?

At present, the pace of work and life is fast, stressful, and poor diet and living habits are very easy to cause digestive tract lesions. Gastrointestinal tumors such as gastric cancer, esophageal cancer, and colorectal cancer have become "killers" that threaten people's health, and are showing a younger trend. Many digestive tract tumors have no symptoms in the early stages. Signs such as pain, blood in the stool, and sudden weight loss indicate that the tumor may be at an advanced stage.

Early detection, early diagnosis and early treatment are the keys to improving the survival rate of patients with gastrointestinal cancer. "Currently, digestive endoscopy is the preferred method for screening for gastrointestinal cancer."

In recent years, China's high-definition endoscopy-based diagnosis and treatment technology has made continuous progress, and it has been at the forefront of the world in the early cancer screening and treatment of the digestive tract.

If you have an irregular long-term life, like to eat pickled, smoked, and grilled food, or have a family history of tumors, you should be classified as a high-risk group, and it is recommended to start gastric cancer screening at the age of 40.

The cure rate of early gastric cancer is very high, reaching more than 90%.

Studies have shown that unhealthy lifestyles and habits such as smoking and drinking can also increase the risk of gastrointestinal tumors. Experts suggest that a healthy lifestyle has a preventive effect on digestive tract tumors, high dietary fiber and the intake of vegetables and fruits can reduce the risk of digestive tract tumors, dairy product intake, exercise, etc., can also play a positive role in effectively preventing colorectal cancer.
