Cancer Detection

Early detection of cancer significantly increases survival rates and makes treatment much more successful.

Higher survival: Finding cancer at stage one can raise the five-year survival rate up to 99% for many cancers.

Simpler care: Early-stage treatments are often less invasive, shorter, and less expensive.

Better recovery: Patients keep more organ function and enjoy a higher quality of life.

• Breast Cancer: Mammograms and clinical exams.
• Cervical Cancer: Pap smears and HPV tests.
• Colorectal Cancer: Colonoscopies and stool tests.
• Lung Cancer: Low-dose CT scans for high-risk individuals.
• Prostate Cancer: PSA blood tests.

The Galleri test is the exact test we discussed earlier-it is currently the best-known brand of a Multi-Cancer Early Detection (MCED) test.

The term MCED refers to a revolutionary category of medical technology designed to screen for many different types of cancer simultaneously with a single routine blood draw, rather than screening organ by organ.

Here is the technical breakdown of how an MCED test like Galleri actually functions:

• The "Liquid Biopsy" (cfDNA): As cells in your body naturally die and replace themselves, they release tiny fragments of their DNA into your bloodstream. This is called cell-free DNA (cfDNA). Tumors do this as well, shedding circulating tumor DNA (ctDNA). The Galleri test isolates these DNA fragments from your blood sample.
• Methylation Profiling: The test does not look for genetic mutations (like a BRCA test would). Instead, it looks for "methylation patterns." Methylation acts like a series of chemical switches on your DNA that turn specific genes on or off. Cancer cells have highly abnormal, distinct methylation patterns compared to healthy cells.
• The Biological "Zip Code": Because different tissue types (like lung tissue vs. ovarian tissue) have unique methylation patterns, the Galleri test's artificial intelligence can read these patterns like a biological zip code. If it detects a cancer signal, it can predict with high accuracy which organ the cancer originated in
• The Primary Goal: Traditional screenings (mammograms, colonoscopies) only look for one cancer at a time and only cover about 5 specific cancers. MCED tests are designed to catch the other 45+ types of cancer (like pancreatic, liver, or stomach cancer) early, before symptoms appear, when they are much easier to treat.

Because this exact Galleri test by GRAIL is not available in India, Indian companies offering alternatives (like EasyCheck360) are utilizing very similar MCED "liquid biopsy" technology to look for these circulating tumor markers.

The exact Galleri test (made by the company GRAIL) is not currently available in India. It is primarily accessible in the United States and the UK.
