Recently, relatives and friends have been asking me about a new technology called [urine test for cancer] for early diagnosis of cancer.
Is this test reliable?
Have regular hospitals been launched?
Could it be fake?
After reading the relevant contents sent by them, it turns out that the so-called [urine drop test for cancer] is only to detect the content of tryptophan and tyrosine in urine to screen and diagnose cancer.
According to the advertisement, as long as 3 milliliters of urine cost several hundred yuan, you can perform the operation at home, and the result can be obtained in 3 minutes. This can kill the gold standard for cancer diagnosis in hospitals now-pathological examination. Traditional pathological examination requires surgery, slices and waiting for several days, and the price is more than that.
Before, there were so-called [a drop of blood for cancer], [a little saliva for cancer], Now there is another [urine test for cancer]. The essence of this wave after wave of [rumors] is the same. It is nothing more than catching people’s fear of cancer. If there is really a technology that can detect cancer at an early stage, without harm to the body, with low cost and no need to go to a hospital, it can find out whether there is cancer. People will definitely be heartache and unable to resist [temptation].
Wait a minute! Have you ever thought that such a good technology has not been introduced into regular hospitals and has not been promoted by the state, but it depends on merchants to publicize and sell it through circles of friends and online shopping platforms. I think, as long as you are willing to think about it a little, you will not believe such things.
These drops of urine and blood were tested for cancer. What was tested?
In fact, the so-called cancer tests only detect tumor markers. Even some indicators, even tumor markers are not. Neither has it been recognized by most experts, nor does it have sufficient research evidence to support it. It is just an opportunity for businesses to publicize and hype, using the concept of Gao Dashang to fool people who do not know the truth.
Although there are indeed some simple and effective technologies under development, they have not been formally applied clinically.
So-called tumor markers, It refers to the production of tumor cells, Or a kind of substance released by body cells stimulated by tumor, It exists in blood, pleural effusion or urine. Although it may be related to the occurrence and development of tumors, However, it can neither be used to diagnose cancer nor to screen cancer. At present, except alpha-fetoprotein can be used as one of the optional screening items for liver cancer and prostate specific antigen can be used as one of the optional screening items for prostate cancer (still controversial), no tumor marker can effectively screen for early diagnosis of cancer.
However, in hospitals, the gold standard for diagnosing cancer is still to obtain human cell and tissue specimens through needle aspiration, puncture or surgery, and send them to the laboratory for pathological diagnosis to see if they are cancer.
Tumor markers are detected by blood drawing or urine retention, The diagnostic value for tumors is very limited, sometimes it can assist in tumor diagnosis, but it cannot be used as the basis for diagnosis of tumors. Because although tumor markers may be related to tumors, they are not unique to tumors. Not only exist in malignant tumors, but also some benign diseases will rise, even in normal human tissues.
In other words, the high tumor marker does not necessarily mean cancer, and the tumor marker of cancer patients may also be normal.
How do you screen for cancer?
So, is it impossible for us to detect and screen cancer early?
Of course not!
First of all, we should attach importance to it psychologically and have the awareness of preventing and checking cancer. Then we should master the basic knowledge of cancer detection. More importantly, it is necessary to take the initiative to carry out cancer screening. If you feel uncomfortable, you should see a doctor as soon as possible.
The so-called cancer screening is aimed at those who are healthy in appearance and do not feel uncomfortable with what. The aim is to screen out people who are likely to have cancer. Early detection, early diagnosis and early treatment are the ultimate goal to reduce the death rate of cancer.
1. Screening Not all cancers can be screened
Cancer screening is not currently applicable to all cancers; There are some cancers and there is no effective screening method. Screening is mainly aimed at common cancers such as lung cancer, colorectal cancer, breast cancer and cervical cancer.
2. Not everyone needs screening
Not everyone needs cancer screening either. Screening is mainly suitable for those people who are more likely to suffer from cancer, such as the middle-aged and elderly people who have increased cancer risk and are suitable for cancer screening. However, children and adolescents usually do not need cancer screening.
In addition, screening is usually aimed at certain cancer high-risk groups, that is, those who are likely to get certain cancers, such as long-term smokers, which are the high-risk groups for lung cancer.
Several Common Cancer Screening Methods
1. Lung cancer
Lung cancer is a malignant tumor that seriously affects human health and is the most harmful. Early detection, early diagnosis and early treatment are the key to improve survival and reduce mortality. Lung cancer screening can be basically done with one move: low dose spiral CT (LDCT).
If it is a long-term smoker or a person with a family history of lung cancer, we recommend to do this examination.
2. Breast cancer
Breast cancer screening methods, for the general risk population, usually use clinical physical examination, breast ultrasound, mammography and other means; For high-risk groups, besides the above methods, breast magnetic resonance is also an important optional examination method.
3. Colorectal cancer
Colorectal cancer is also one of the malignant tumors recognized internationally that can reduce mortality through population screening. Screening mainly adopts stool occult blood test, stool DNA examination, sigmoidoscopy, CT colonography (CT virtual colonoscopy), colonoscopy and other means.
Other cancer screening methods and how to be considered high-risk groups can be consulted by regular tumor prevention and treatment institutions and specialists.
Finally, I would like to remind you once again that you must go to regular medical institutions for cancer screening and do not listen to all kinds of commercial publicity and advertisements.
