Beat the Trend of Early-onset Colon Cancer through Timely Screening
Colorectal cancer cases rising in young adults is a concerning global trend. The best way to beat the trend is to prevent or detect the disease early through timely screenings.
On March 9, 2026, I underwent two diagnostic procedures under the care of Matthew Timothy Clark, M.D., and I am truly grateful for the care I received. Dr. Clark is the kind of physician every patient hopes to find. From the first consultation through the day of the procedure, he demonstrated professionalism, clarity, and experience. He took the time to explain the process, answer my questions, and make sure I felt informed and comfortable. Most importantly, he inspires confidence—you truly feel you are in capable and trustworthy hands from beginning to end. I would also like to express my special gratitude to Cameron, who made that day uniquely human. Just before the procedure, while preparing to go under anesthesia, I shared a personal concern with her. I told her that if, for any reason, I did not wake up, the person coming to pick me up should please make sure my dog, Emma, was rescued, because she was alone at home. For a brief moment, the room became very quiet, and Cameron understood. She looked at me with calm certainty and said: “Don’t worry. You will wake up.” That simple reassurance meant more than she probably realized. When patients close their eyes and place their trust completely in the hands of others, a few sincere words can make a profound difference. Thank you, Dr. Clark, Cameron, and the entire team for your professionalism, compassion, and dedication. I highly recommend them.
