Intuition, Self-Advocacy, and Support: Key Lessons from Mark’s Experience with Stage 3B Colon Cancer
Mark found out he had stage 3B colon cancer at 35, a life-altering diagnosis. He began having cramping episodes of varying intensity in 2020. Doctors initially mistook these for appendicitis. However, his intuition pushed him to get more tests. His hunch proved correct after a colonoscopy revealed a tumor that was later confirmed as cancerous.

Mark had surgery to remove a section of his intestines and several lymph nodes. Although his stage 3B colon cancer was negative for a genetic component like Lynch syndrome, it had spread to his lymph nodes, making chemotherapy necessary. Mark had to choose between a prolonged or intense chemo regimen and opted for the latter, enduring side effects like neuropathy and fatigue.

The physical challenges Mark had to overcome and the psychological strain of accepting help reshaped his outlook on life. After his treatment for stage 3B colon cancer, he was declared to have no evidence of disease in 2021. Mark now shares his story to raise awareness of cancer and inspire others.
