Recent research has suggested that a misplaced or tampered DNA can be detected by conducting a blood test, which further helps provide information on whether a prostate cancer patient is returning into former state.
The researchers from the US have proposed that abnormalities in genetic pattern called copy number variations (CNVs) can be directly linked to relapsing cancer. It has been further explained that CNVs are large chunks of genetic code, which either have duplicated DNA or gaps created due to the absence of DNA.
The researchers have reported that they have been able to discover the presence of CNVs in blood and tumors of patients diagnosed with cancer. Moreover, it has been emphasized that the researchers with the help of detection of these abnormalities were able to predict 81% of reoccurring cancers, which relapsed after an initial treatment.
Nevertheless, it has been subjected that they were even able to acknowledge the growth of relapsing cancer, which was stated to be aggressive or slow-growing. It has been reported that the researchers were able to predict that
69% of the relapsing cancers were aggressive ones.
It has been recalled apart from blood test, CNVs from tumor or healthy prostate gland, can even be analyzed to detect reoccurring cancer, however, the method is subjected to be less accurate than the previous one.
