If you get 4 tests done, cancer will be detected much earlier, hope of survival will be guaranteed, doctor told their names.

4 Test for early detection: When someone gets cancer, it does not come from outside. The cells of the body itself turn into cancer cells. It takes years to change it. This means that cancer may take 5-7 or even 10 years to become a complete disease. During this period not a single symptom of cancer is visible. Symptoms like pain, bleeding or weight loss appear when the disease has progressed significantly. When such a time is reached, treatment becomes difficult and the chances of survival may also decrease. In such a situation, the question is whether cancer can be detected in advance. Because treatment of most cancers is possible only when it is detected early. Catching diseases like colorectal and lung cancer in their early stages can extend life by several months to years on average. If the tumor is caught locally then the chances of cure with treatment are very high. Since it takes years for a healthy cell to turn into a cancer cell, modern technologies check whether any changes are taking place in the cells or not. This has made it possible to detect early pre-cancerous changes in the tissue. That is, if there is a change in the cell and the DNA inside it, then whether it will turn into a cancer cell can be known by testing it. In such a situation, that particular tissue will be removed and hence cancer will not occur. For this, Dr. Vaas has advised 4 types of such tests.

Four tests to detect cancer early

1. Standard Screening Test-There are many tests involved which every adult should undergo after 25 years of age. These include mammogram for breast cancer, Pap and HPV test for cervical cancer, colonoscopy or stool test for colorectal cancer, low-dose CT scan for lungs in smokers and PSA test for prostate cancer. In fact, through these tests, early stage cancer or pre-cancerous changes can be detected. For example, if someone has colon cancer through the anus, he will start having colon polyps. Similarly, if there is cervical cancer in women then polyps will start forming in the cervix. This is a group of cells in which cancerous changes begin to occur. This test detects this. For example, colonoscopy is called the gold standard because it not only detects precancerous polyps but also removes them, directly reducing the risk of future colorectal cancer.

2. Gallery and Multi-Cancer Blood Test-The Gallery test is a multi-cancer early detection blood test that looks for abnormal patterns in the cell-free DNA released by cancer cells into the blood, rather than finding any one specific type of tumor. Large screening studies such as Pathfinder 2 found that adding the Galeri test to routine screening increased cancer detection by more than sevenfold within a year, and about three-quarters of these cancers were for those for which no standard screening is currently available. MCED tests cannot prevent cancer directly but they can catch those hidden and aggressive tumors years earlier. It catches cancer in ovaries, kidneys or throat first.

3. Genetic Testing-This test is for those people whose family has already had cancer. This test looks for gene mutations that increase the risk of cancer. Such as BRCA1/2, TP53 and other genes which significantly increase the risk of breast, ovarian, colorectal and many other cancers throughout life. Unlike imaging or blood tests, this test is usually done once in a lifetime and can detect risk long before any cells develop pre-cancerous changes. This allows screening and prevention to start sooner and be more intensive. This test is also necessary for people who have gene related syndrome. Such as hereditary breast–ovarian–pancreatic syndrome or hereditary colorectal–endometrial–gastric cancer syndrome.

4. Full-body MRI- Whole-body MRI is an imaging test that scans the entire body at once, from head to waist, often including the arms and legs. It does not involve radiation, and is intended to find tumors anywhere in the body. Current guidelines recommend full body MRI primarily for people at high genetic risk of cancer. Studies in high-risk populations have shown that WB-MRI can detect significant and often asymptomatic cancers that are not seen with other imaging. This test increases the chances of treatment in such patients. However, all these tests are not such that they should be done every year. These tests should be done on the advice of doctors.
