Prostate cancer is a slow growing cancerous tumor.
It puts forth symptoms at a fairly advanced stage. However if people undertake yearly medical checkups including
prostate cancer tests, (which they are supposed to do after 40) the chances of early stage detection of the same are bright. Researchers and Scientists of John Hopkins Oncology Center have proved that the measuring of the chemical process linked with genetic change initiated with the prostate cancer makes early stage detection of prostate cancer. Always detection of cancer at preliminary stage facilitates complete cure. U.S and U.K scientists are simultaneously developing a quick test for prostate cancer.
It will take only three minutes to perform.
They collect the sample of prostate fluid via a small needle inserted in the patient's body under local anesthetic. This will be a landmark in testing of prostate cancer.
Dr A Prasanna de Silva, chair of the organic chemistry at Queens University, Belfast, U.
K said that the new test was "A convenient and quick method which provides early warning of prostate cancer which will bring relief to many men".The most popular test for cancer throughout the world is the Prostate specific Antigen (PSA) prostate cancer test. Prostate gland secretes a protein called PSA and if the secretion value is high, it is indicative of the presence of cancer forming cells. This test along with Digital Rectal Examination helps Physician to accurately measure the size of the prostate gland. Maryland-based Pharmaceuticals Scientists have found that a protein-actually an enzyme called HAAH - might as well prove to be a biomarker.
This means that this biomarker test is much more sensitive and specific for cancer detection, compared to all the present day testing.
By means of this early detection, the prostate cancer recurrence can also be prevented.
By means of another simple test called DNA test, which pinpoints risk genes, the Scientists of the Swedish Medical University Karolinsk Institutet hope to predict occurrence of prostate cancer by identifying the risk genes in patients. If the risk genes are 4 to 5 times in excess, the onset of prostate cancer is a certainty. Even in the cases of partial cure setting in, the risk of prostate cancer recurrence is possible.Now let us look at the nanoparticle prostate cancer test.
Here the golden nanoparticles are first mixed in a solution. Then the patrient's blood is dropped in the nano solution.
Then the nano particles seek put the protein.
In case of protein particles being present, then the protein particles surrounded by the nanoparticles.
When there is cluster formation, cancer is present, is the inference. Otherwise in case of no cluster formation, obviously no cancer formation needs to be suspected.
The question whether obesity is an impediment for prostate cancer test has been studied deeply by the Texas University Health Science Center in San Antonio. They concluded that in obese men the sensitivity of PSA testing is blunted. What the Doctors conclude is that more estrogen is produced by obese men, affecting testosterone levels and could affect the cells that produce antigen in the test.
