15 Dec Lab Tests That Can Detect Cancer?
The Grail’s Multi-Cancer Early Detection (MCED) lab test and the genetic cancer test are the most effective and widely used cancer detection tests. They are thorough tests that can determine if you have cancer or whether you have a genetic propensity to developing cancer and tumor cells.

Laboratory tests play an important role in the ongoing pursuit of early cancer detection and effective treatment since they provide essential information on the presence and characteristics of malignant cells. These modern diagnostic devices have become crucial in the field of oncology, enabling medical practitioners to precisely diagnose and monitor many types of cancer. Remarkable advancements have been achieved in the realm of cancer detection, encompassing many techniques such as imaging investigations and blood tests.
Grail’s Multi-Cancer Early Detection Lab Test
Multi-cancer early detection (MCED) technology is a promising tool in the battle against cancer. Currently, many cancers are detected at a late stage, limiting treatment options and leading to poor outcomes.
Recent advancements in machine learning and next-generation sequencing have made MCED testing possible. In 2021, GRAIL introduced the Galleri® test, the first commercially available MCED test of its kind. This test uses a single blood sample to identify a common signal shared by multiple types of cancer, including those that are not typically screened for. MCED testing significantly increases the chances of detecting cancer at an early stage, allowing patients to be screened for over 50 different types of cancer based on this common signal.
How The Grail’s Multi-Cancer Early Detection Lab Test Work
The Galleri test involves sequencing DNA fragments present in the bloodstream. Subsequently, a machine learning algorithm is utilized to determine if these DNA fragments are from cancerous or healthy cells. In the case of healthy cells, the system further predicts the specific kind of organ tissue associated with the cancer signal.
DNA shedding
When cells in the body die, whether they are healthy or sick, they release small amounts of DNA into the bloodstream. This is called DNA shedding. If there are cancerous cells in the body, they also release DNA, so both healthy and cancerous cell fragments may be found in the blood. Methylation is involved in determining whether each DNA fragment in the blood came from a healthy cell or a cancerous one.
Methylation
Methylation is a natural process that involves the addition of methyl groups to the DNA molecule. This process may selectively activate or deactivate certain areas of DNA, so adjusting the function of a DNA segment without changing its sequence. Demethylation often turns genes “on,” while methylation turns them “off”.
Genetic Cancer Lab Test
Genetic testing is the process of using diagnostic procedures to search for specific gene alterations, or mutations. There are now many different genetic test types in use, and more are being created.
When a Genetic Cancer Lab Test Should Be Done?
Genetic testing involves employing diagnostic methods to identify specific gene changes or mutations. Currently, there is a wide array of genetic test types in circulation, with ongoing development of further ones.
- An individual with a significant familial predisposition to a certain type of cancer should undergo examination to see if they possess a genetic mutation that increases their susceptibility. If individuals have an inherited mutation, they have the option to undertake screening tests for early cancer detection or take measures to decrease their risk. An instance of this would be doing screenings on individuals who have several family members with a history of breast cancer, in order to identify any modifications in the BRCA1 and BRCA2 genes. These genes are recognized for increasing the likelihood of developing breast cancer and certain other types of cancer.
- An individual who has previously been diagnosed with cancer, especially if there are further signs that the disease may have been caused by an inherited mutation (such as a strong family history, early detection, or an uncommon condition, such as male breast cancer). Genetic testing can determine an individual’s predisposition to specific forms of cancer. Assessing the need for mutation testing might also be advantageous for other relatives.
- Family members of an individual who carries a genetic gene mutation that has been demonstrated to increase their risk of acquiring cancer. Testing can help individuals determine if they need screening tests to detect cancer early or if they should focus on reducing their risk.
Conclusion
In the realm of modern healthcare, the significance of cancer diagnostics cannot be overstated. Efficient and accurate diagnosis plays a crucial role in overcoming cancer, as seen by the intricate process of navigating through laboratory tests. The early identification of cancer enhances the probability of positive outcomes by facilitating prompt intervention and aiding in the development of personalized treatment approaches. Our commitment to enhancing our ability to detect cancer at an early stage, when intervention can be most effective, is seen in the continuous advancement of diagnostic instruments.
