Cancer refers to malignant tumors originating from epithelial tissues and is the most common type of malignant tumor. Healthy cells age and die on their own, while cancer cells continue to proliferate and transfer to other organs. Cancer is not a single disease, but a combination of thousands of diseases. Symptoms usually include persistent headaches, weight loss or loss of appetite, long-term pain in the bones or certain areas of the body, nausea or vomiting, persistent low-grade fever, persistent or intermittent, and repeated infections.
What are the carcinogenic factors?
Internal reasons (genetic factors, mental factors, immune factors, nutritional factors, bad habits), external reasons(physical factors, chemical factors, biological factors).
Breast cancer, stomach cancer, bowel cancer, etc. are all hereditary. If there are such cancer patients in the family, the cancer rate of offspring will be higher.
Personal emotions can regulate the normal level of endocrine in the body to a certain extent. Therefore, we should keep our body and mind relaxed and in a good mood every day. If you are in bad moods such as depression, anger for a long time, this will cause endocrine disorders and virtually increase the risk of cancer. Thyroid cancer, ovarian cancer, breast cancer, and other cancers have a great relationship with endocrine disorders.
Every normal person will have a certain degree of resistance, the body’s immune system monitors and eliminates cancer cells and effectively prevents abnormal proliferation and deterioration. If some reasons lead to the weakening of immunity, the human body will not be able to be timely and effective and to remove cancer cells from the body, inhibition of cancer and weakened ability to fight cancer will lead to an increase in the incidence of cancer.
A balanced diet is one of the important conditions for human health and survival. If you have a long-term partial eclipse or diet, nutrition will be imbalanced. Lack of important nutrients such as vitamins, minerals, cellulose, and protein can cause disorders in the body and cause cancer.
The fast-paced life makes most people unable to take into account their dietary health problems, do not eat on time, eat too fast for a long time, eat very hot food, sit for a long time, and lack exercise. Pickled and barbecued foods increase the risk of stomach cancer. Long-term smoking will increase the incidence of lung cancer, esophageal cancer, and throat cancer.
Prolonged exposure to strong ultraviolet light can cause skin cancer or melanoma. Long-term exposure to ionizing radiation such as X-rays and gamma rays can cause chromosomal mutations, activate cancer factors, and increase the risk of cancer.
A large number of chemicals can be latent in the human body and increase the risk of cancer. The polycyclic aromatic hydrocarbon gases released during the burning process of smoked and roasted food, motor oil, and tobacco are carcinogenic. Workers who have long-term exposure to printing and dyeing materials and rubber products are also at risk of developing bladder cancer. Nitrosamines in pickled foods and Mycotoxins in moldy food can cause stomach cancer, liver cancer, etc.
DNA virus or RNA virus invades the body to cause cancer in the body, such as the occurrence of liver cancer and hepatitis B virus. T-lymphocytic leukemia virus is related to T-lymphocytic leukemia.
After some of the above-mentioned more detailed introductions about cancer, everyone should have a general understanding of this. Next, we popularize some prevention methods.
How to effectively reduce the risk of cancer?
Although cancer is terrible, the greatest risk of cancer can be avoided through treatment and prevention.
The International Union Against Cancer (UICC) proposed that 1/3 cancer can be prevented, 1/3 cancer can be cured through early diagnosis, and 1/3 of cancer patients can improve the quality of life and prolong survival through effective comprehensive treatment. In daily life, we can pay attention to these aspects:
1.Eat a comprehensive and balanced diet
Pay attention to balanced nutrition, eat fresh fruits and vegetables, quit smoking, limit alcohol consumption, and also eat no alcoholic beverages containing strong carcinogens, betel nuts, sauerkraut, and pickled smoked foods, and avoid overheated beverages that cause cancer (high At 65°C).An appropriate amount of exercise. People often say that “life lies in movement”. 33% of cancers occur in obese people. Esophageal cancer, pancreatic cancer, colorectal cancer, uterine cancer, kidney cancer, and breast cancer prefer obese people. The incidence of breast cancer in overweight women increases by 20%-40%. Therefore, reasonable exercise and proper weight loss are necessary.
2.Maintain a good attitude
The new model of cancer diagnosis and treatment is a multidisciplinary consultation composed of medical oncology experts, surgical experts, radiotherapy experts, pathologists, radiologists, and psychologists. A good mentality also has a place in comprehensive treatment. For ordinary people, maintaining a good mood helps fight disease.
3.Pay attention to cancer prevention physical examination
Regular physical examinations and strengthening awareness of body screening are important. Many cancer patients go to the hospital only after they develop symptoms, and then they are often found to be in an advanced stage.
Therefore, regular targeted physical examinations should be performed before symptoms appear to detect cancer traces early.
