About Howard Brown
Howard Brown is a two-time Stage IV cancer patient, survivor, advocate, technology entrepreneur, husband, dad and avid basketball player. In 1989 at the age of 23, Howard was diagnosed with Stage IVe Non-Hodgkin's Lymphoma. After failing three chemotherapy regimens, he had an allogeneic (from a donor) bone marrow transplant from his twin sister who was an exact HLA match. That, along with massive chemotherapy and full body radiation saved his life. Twenty-six years after achieving remission, Howard was diagnosed with Stage III Colon Cancer at age fifty via a standard colonoscopy. After two colon resection surgeries, intense chemotherapy and a failed clinical trial he turned metastatic Stage IV and discovered the cancer had spread to his liver, peritoneum, omentum and small bowel. After salvage second line chemotherapy showed some regression (shrinkage), Howard underwent Cytoreduction Surgery (debulking / removal of live and dead cancer cells) with Heated intra-peritoneal chemotherapy (hot chemo wash to kill micro cancer cells– (CRS HIPEC). Howard is currently considered No Evidence of Disease (NED) at this time after 9 consecutive CT scans. He serves as the Board Chair and President of Colontown, an organization that serves over 11,000 patients and caregivers with colorectal cancer. Howard is a proud graduate and past trustee of Babson College, #1 for entrepreneurship, and lives with his family in Birmingham, Michigan.
