Liquid biopsy cancer test is normally used to look for signs of the deadly disease. It examines the bodily fluid of a person, in most cases this happens to be semen, saliva, urine or even other fluids. The most significant benefit of utilizing the liquids mentioned above is that their accessibility is easy and collection is quite fast. In addition, collection is non-invasive thus does not cause discomfort or a lot of pain. Liquid biopsy is an approach with great promise for cancers such as those of the pancreas and the lung. This means that it will save many lives.
In recent times, liquid biopsy is routinely used for the diagnosis of cancer but it also has other applications for people with cancer. The reasons for this include the following:
This cancer test can be used to monitor whether the disease is growing or not. An easy test is relatively quick to perform. Unlike tissue cancer, doctors do not require to directly access the tumor directly for them to gather information with regard to the cancer. This allows doctors to take many biopsies over a period, therefore monitoring if the tumor is growing. Ultimately, this enables them to determine if a treatment is effective and the approach to take.
Since the test detects signs of cancer directly from a tumor, this enables it to analyze the genetic material of the tumor. This allows doctors and researchers to utilize the analysis for learning genetic mutations in a tumor, comprehend its aggressiveness as well as its likelihood of spreading. Good treatments can therefore be recommended for specific genetic mutations.
The application for liquid biopsy is bound to expand because it is a powerful tool and technology keeps advancing.
Liquid biopsy cancer test has numerous benefits, the main ones include the following:
• It determines if a cancer is present and its location.
- It determines if the cancer has spread in the body.
- The genetic changes that the tumor has.
- The type of treatments that might work in fighting the cancer.
- If the treatments are working or not.
- If there is cancer left following treatment.
ChallengesThere are a few challenges that are associated with liquid biopsy cancer test, the notable ones are as follows:
Tumor markers regardless of the specific type have low concentrations in blood of a person diagnosed with cancer. Blood has exosomes, genetic material and cells regardless of whether a person is healthy or not. This makes it difficult for current technology to detect a cancer signal.
Different tumor cells and genetic mutations
Tumors have various cells that might have numerous different cells with an array of genetic mutations. The determining factor is the tumor’s location and how it has evolved.
Liquid biopsy has many uses and it has facilitated major steps in cancer treatment. It is a life-saving technique, particularly for cancers that were initially hard to diagnose during early stages like pancreatic cancer, brain cancer and lung cancer. Liquid biopsy will continue to flourish for many reasons, some of which have mentioned above. Here is a great resource on liquid biopsy.
