Cancer and cancer screening
Oncology refers to the malignant tumor originating from epithelial tissue, which is a common type of malignant tumor. The initial clinical manifestations of cancer are almost asymptomatic, and even if there are symptoms, they are often nonspecific. When patients have symptoms, they are basically in the middle and late stages. Pre-cancer detection is basically found unintentionally through physical examination or other examinations.
Cancer screening is based on different organs, even if targeted cancer screening, the results are still relative, not absolute. Moreover, not all cancer examinations have effective screening methods. At present, only some cancer examinations have clear and effective screening methods. Therefore, the medical examination package should be increased or decreased according to your age, gender, occupation and physical condition.
Several "culprits" leading to cancer
Unhealthy diet leads to obesity: some people like a light diet, while others don't eat meat, but the British substances needed by the body are almost the same, which will lead to different constitutions in the long run. Our long-term dietary preferences are likely to affect our health, and many diseases are "eaten". The inducement of many cancers may be related to diet, not just the renal malignant tumor mentioned above, because obesity and hypertension are directly related to our diet. A large number of experiments show that long-term unreasonable eating habits are the direct cause of cancer.
Lack of exercise, physical deterioration: after my friend's father retired, he spent almost all his remaining time on iPad games except accompanying his wife to the market to buy food, taking a walk after a nap and cooking at home. Find a comfortable posture, lean on it most of the day, no more than 3000 steps a day, and rarely get up early. Doesn't mean that others run 5 kilometers every morning, I will do the same! The standard of exercise should be suitable for one's physical condition and meet the consumption of extra energy, instead of blindly copying other people's fitness plans. Reasonable and moderate exercise is the premise of good health.
Smoking seriously damages health: Smoking is the cause of many diseases, and its impact on human body is far beyond the respiratory system we are familiar with. Specifically, it may also endanger renal function, lead to a decline in bone mineral density, and be vulnerable to pathogens, which is very harmful to the lungs and brain. Besides being kind to yourself, you should also consider the passive inhalation of second-hand smoke by your family! Quit smoking and drinking, save yourself first, and you can better protect your family.
Irregular physical examination ignores his own health: a friend's father always thinks that physical examination is redundant and does not pay attention to his own health. I didn't know the importance of the matter until my body called the police. This is how many diseases missed the best treatment time. Adhere to regular physical examination and monitor physical changes in time. Even if you are sick, you should prescribe the right medicine. If early detection and early treatment, you will suffer a lot less. Don't care.
We don't always find canceration in the early stage of cancer, but most of them have reached the middle and late stage when they are detected.
Location and size: tumors that usually occur on or near the body surface are easy to find, such as thyroid cancer, and asymmetry on both sides of the neck is easy to see. But if the tumor is located in the internal organs of the body, it is difficult to find. On the one hand, the general physical examination is not targeted, and early cancer will not affect physiological indexes such as blood routine, liver function and renal function. Secondly, there are often no pain nerves in human organs, so small pieces like liver, brain and lung often don't feel anything unless they are big enough to cause physical discomfort.
Symptoms: People are actually very sensitive to pain. For example, patients with lung cancer will have a slight cough in the early stage, patients with liver cancer and gastric cancer will have a slight abdominal discomfort, and patients with brain cancer will have a slight headache. These are very common typical symptoms. For this mild symptom, most people will choose to be patient, which will lead to prolonged illness. Therefore, even if they go to see a doctor because of a little discomfort, they can't say that there is no tumor.
Growth mode: Tumor growth modes generally include expansive growth, exogenous growth and invasive growth. If it is a malignant tumor, the growth mode is often invasive, that is, the tumor will grow along the internal structure of the organ, with extremely rapid growth and easy metastasis, and sometimes it is difficult to find the tumor even in the primary site. So this kind of tumor is usually found in the middle and late stage.
Facts have proved that many times our bodies look healthy, only superficial. Wrong living habits, bad eating habits and lack of long-term accumulation of exercise may all be hidden bombs buried deep in our bodies and explosive. Most diseases are caused by our wrong operation.
Many diseases have no obvious symptoms at the initial stage, and self-testing is difficult to find. Therefore, physical health is not necessarily real health. Only by adhering to healthy eating habits, giving up bad habits that destroy physical function, regular physical examination and proper physical exercise are the correct ways to shape good health.
Everyone has some cancer cells in his body, but everyone's resistance is different. As long as he is in a good mood and optimistic, he will definitely drive cancer away. A good attitude, the sky is falling with one's head held high, as long as you are alive, everything is possible, and the most successful thing for a person is to defeat yourself!
