Nearly 4 million new cancer patients appear on the mainland every year, and 2.3 million people die from cancer every year, that is, one person dies of cancer every 4 minutes.
Many cancer patients, in the early stage is not found or detected, the vast majority of patients found are already in the middle and advanced stages, the treatment effect and survival rate is far less than the early stage, why is this so?
Why are many cancers, as soon as they are discovered, intermediate and advanced?
Difficult to detect early
At present, the examination method used can only detect tumors of about 1 centimeter, and there are already almost 1 billion cancer cells in tumors as large as 1 centimeter.
When there are only one or two cancer cells in the body, the detection methods currently used cannot be found. So that's why many cancers can only be detected until they progress.
Early patients have no symptoms
Most cancer patients, in the early stages, do not experience much discomfort, because the development of cancer is also a slow process.
As the cancer continues to develop in the body, the cancer grows larger and larger, compressing into the surrounding tissues or blood vessels, and then the patient has obvious symptoms.
Moreover, the symptoms of some cancers at the beginning are very similar to other common diseases, so it is difficult to attract people's attention.
There is no targeted screening
Although people's awareness of physical examination has increased, the examinations done are also ordinary examinations, and there is no special screening for cancer.
Therefore, if you want to screen for cancer early, you still need to do a special targeted examination of cancer so that you can detect the presence of cancer cells early.
The degree of malignancy of cancer cells
The degree of malignancy of cancer cells of each cancer is different, and the cancer cells of some tumors are relatively high, so they develop rapidly, such as liver cancer, pancreatic cancer, leukemia and so on.
And some cancer cells develop much slower, and some don't even develop to more than 1 centimeter, and they don't develop, so it's hard to find.
What should I do if I want to detect cancer cells early?
Do targeted screening, which is the most important point, such as long-term smoking patients, then the probability of lung cancer will be higher, so should be targeted screening lung cancer test.
If it is a hepatitis B patient, then the probability of developing liver cancer is much higher, so the patient should regularly check alpha-fetoprotein and liver function.
Choose the appropriate anti-cancer screening for yourself, so that the tumor can be detected early, so that it can be treated early and achieve better treatment effect and survival cycle.
The most important thing is to live a healthy life, a regular schedule, a balanced diet, improve the immunity of your body, and prevent the emergence of diseases.
