Rumors said: pregnancy tests can detect testicular cancer.
A rumor Wikipedia:
Pregnancy test strip in the detection of - human chorionic gonadotropin, which indeed may be increased in the event of testicular cancer. However, the pregnancy test strip is not a good method of screening for testicular cancer, testicular cancer because not all, there will be a phenomenon of elevated -hCG. And the real test strip can detect positive patients with testicular cancer only a small part. Some of it is more sensitive to blood hCG testing to detection, but may also have a false positive situation.
Demonstration:
The reason for the phenomenon mentioned in rumors that the pregnancy tests used to test whether or not the index pregnancy is Beta-human chorionic gonadotropin (referred to as the -hCG, - human chorionic gonadotropin), this indicator is cancer testicular cancer one of the indicators.
Now take pregnancy tests test their urine, can test a tumor marker for -hCG, why not clinical pregnancy tests, this super simple way to do screening for testicular cancer? American Cancer Society (American Cancer Society) pointed out that -hCG blood test, for certain testicular cancer was found, staging, tracking is important, but some patients with testicular cancer elevated -hCG, may also have breast pain , the phenomenon becomes large, however, not all testicular cancer, will have the phenomenon of elevated -hCG.
In addition, some testicular cancers secrete male hormones and some will be the female hormone secretion, the former will make the patient's beard, increased body hair, which may make a man's breasts larger or lost libido. In most cases, testicular cancer, there may be a painless lump in the testicle, so testicular swelling or larger. Some patients may feel heavy or scrotum or lower abdomen pain. So, pay attention to their testicles change may be more important than the pregnancy test stick testicular cancer.
As to why the risk of testicular cancer would be a young man of eighteen? In fact, testicular cancer is one of the small number of patients younger cancer. US National Cancer Institute (The National Cancer Institute, called NCI), that is noted for twenty to thirty-five men, testicular cancer be more common cancers.
According to the Department of Health National Health Council, the latest annual report for 2008 of cancer registration, also showed that the median age of patients with testicular cancer in Taiwan is twenty-eight, the highest age-specific rate of occurrence is twenty years old, followed by twenty-five and thirty.
Clinically, the incidence of testicular cancer is very low, if the cancer has not spread to the outside before the testicles, was found early, the five-year survival rate can be as high as 99%, the cure rate is quite high. Now known incidence of testicular cancer, the relationship between cryptorchidism, testicular cancer family history more closely, the higher the risk of such men can be regular self-examination, to early detection of abnormalities.
But pregnancy test strip is not a good method of screening for testicular cancer, because although hcg can be used as an auxiliary testicular cancer markers, but the real test strips can detect testicular cancer patients positive for only a small part. Some of it is to be more sensitive to detect blood hcg detected, but may also have a false positive situation. There is also no evidence that the use of pregnancy test strip male population screening in the early detection of testicular cancer and help to reduce mortality (other tumor marker is also true). In addition the above article also said that not all of testicular cancer, will have elevated -hCG phenomenon.
