Patient Guiding Handbook

“I had no personal or family history of cancer, but I decided to take the SPOT-MAS test. It detected ctDNA signals that pointed to possible tumors in my stomach and lung. I then underwent a gastroscopy and biopsy, which confirmed poorly differentiated signet ring cell adenocarcinoma in my stomach. I had a total gastrectomy with D2 lymph node dissection, and the post-surgery analysis showed that the cancer had already spread to my lymph nodes.

This experience made me realize how silent stomach cancer can be—and how critical early detection with SPOT-MAS truly is.”

“My mother passed away from stage IV ovarian cancer. Since there’s no regular screening available for this type of cancer, it was only discovered when it was already too late. After that, I lived with constant fear and anxiety — wondering if I might have cancer too. That’s why I decided to take the SPOT-MAS test.

When I received a negative result, I felt an overwhelming sense of relief and joy. I know I can’t control everything, but I can take action. From now on, I plan to do annual screenings. If anything ever appears, I want to catch it early — when it’s still treatable.”
