Tumor markers - a group of biologically active substances produced in the body during certain events (pregnancy, chronic and acute inflammatory processes, the growth of benign and malignant tumors). Unfortunately, the method for determining tumor markers in the blood is rather nonspecific and far from always sensitive. The values of tumor markers can significantly increase with bronchitis, colitis, etc., and can be normal with a common process at the 4th stage. Tumor markers are excellent for inter-interval monitoring after completion of the main treatment with an established diagnosis. A number of indicators are still used by oncologists in conjunction with instrumental diagnostic methods. But the diagnosis is never made on its basis. If you care about your health, it is best to undergo comprehensive examinations designed and selected based on your individual risks.
In general, doctors neglect such analyzes, because in the early stages, if an education is found, the tumor marker is useless, they believe it only shows a predisposition, and the education can be not only malignant, but also benign. And so to date, no research will give an exact answer whether there is cancer or not, only the predisposition can be outstripped. And if you have found an education, the doctor will not even say it is benign or cancer. The doctor will offer to do a histology with an operation, the only way you can find out cancer is not cancer. Well, if there is no education and you just want to get tested, tumor markers will show a predisposition to cancer, and heredity also affects, but each person is different.

I advise you to read the interview of the oncologist, director of the Cancer Prevention Foundation Ilya Fomintsev on echo.msk.ru that if you just get tested for tumor markers, they will not be indicative. I quote:
"- The analysis for tumor markers is a very highly specialized topic, for oncologists, a kind of trick. It was never intended to diagnose primary cancer. It never happened. Initially, it was just some practically applicable scientific research: it was already possible to track a tumor marker among patients in dynamics.
And from the late nineties, early two thousandths, it suddenly acquired an explosive character, tumor markers began to be used commercially, for diagnostics. But, sorry, citizens, there was no not a single study that could confirm their effectiveness. You see, each diagnostic method has two parameters: specificity and sensitivity. So tumor markers have very low sensitivity and specificity.
Simply put, translated into Russian language, this means that if you did an analysis for a tumor marker and it is elevated, this does not mean that there is cancer, and if the level is normal, this again does not mean that there is no cancer. "
In general, you need a serious comprehensive examination under the guidance of an experienced doctor.
If we talk about the early diagnosis of cancer, then there is no single analysis. Currently, scientists have found biochemical blood markers, with an increase in which we can talk about a high probability of detecting cancer in one or another organ. If we talk at the philistine - not a medical level, it is important to understand that there are various tissues that consist of their own, not similar to others, cells. So the heart is built from heart cells (cadiomyocytes), the liver from liver cells (hepatocytes), the brain from neurons, bones from osteocytes, etc. It is important to understand that cancer can develop from each individual tissue and it will have a different cellular structure, which means that different specific markers corresponding to one or another type of tissue are needed for its diagnosis. That is why there is no one laboratory analysis in the world, according to the results of which it is possible to diagnose cancer.
If a person has a predisposition to the onset of this or that oncological disease (for example, the father was ill with stomach cancer, that is, there is some kind of genetic connection), then it makes sense to purposefully observe the appropriate doctor who will prescribe himself the frequency of various tests that can reveal some kind of oncology.
It is impossible to answer how often these tests need to be taken. Let me give you an example. There is a type of cancer called cervical cancer. The peak of this disease in the population occurs at 32-35 years and 60-65 years. It is precisely the patients with the aforementioned age that should be kept under special control.
As you can see, there are a lot of nuances and today medicine has not reached such heights to unequivocally answer your question.
