As far as I know, cancer is generally found mostly because of the following situations:
1. Feeling unwell, go to the hospital for examination.
2. I went to the hospital for examination because of other diseases, and it turned out to be some kind of cancer.
3.？ Routine physical examination, found abnormal, further examination found cancer.
4. Targeted cancer examination, regular examination like routine physical examination, and find abnormalities.
For 4, there is no universal examination, only special examination for a specific cancer, which is the most common and widely used, including molybdenum target examination for breast cancer, Pap smear examination for cervical cancer, PSA antibody blood test for prostate cancer, blood test for colorectal cancer and colonoscopy.
From a medical point of view, of course, the problem of direct symptoms is the most serious; No abnormal cancer was found, and the situation was the lightest.
Therefore, there is generally no big objection to the cancer detected, because the direct symptoms have affected normal life, most of the time in the middle and late stages, and need immediate treatment. But for 2-4, that is, cancer with no abnormal sensation is the most controversial, and the controversy gradually increases from 2 to 4.
There are many kinds of cancer, and the examination methods are also varied:
0 1, intracranial tumor, head CT can be done.
02. Nasopharyngeal tumor can be treated with nasal endoscope and head CT.
