Facing a colorectal cancer diagnosis at 35 after being denied screening due to his age, Zed Dhalla developed a do-it-yourself fecal immunochemical test (FIT) kit that is currently awaiting Health Canada approval, CTV News reported.
Early Onset Colorectal Cancer Rises in Younger Cohorts
- Epidemiological Shift: Medical literature confirms a rising incidence of early-onset colorectal cancer among birth cohorts born in 1980 or later, challenging traditional screening age cutoffs.
Medical Providers Deny Zed Dhalla Early Screening
Zed Dhalla’s journey toward developing an alternative screening tool began years before his own formal diagnosis. At 33, cognizant of a strong familial history of cancer that included his mother, Yasmin, battling ovarian cancer and his father, Shabbir, fighting colorectal cancer, Dhalla proactively requested a colonoscopy. According to CTV News, healthcare providers rejected his request on the basis of his youth, citing established clinical guidelines that set baseline screening protocols well above his age bracket.
That denial forced a two-year delay before symptoms became undeniable. By his first wedding anniversary in 2025, alongside his spouse Marlisa Madden, Dhalla experienced persistent fatigue, bowel habit alterations, and hematochezia, or blood in the stool. Subsequent clinical evaluations confirmed a diagnosis of colorectal cancer at age 35.
Canadian Provinces Differ on Screening Age Thresholds
The institutional reluctance to screen younger adults exists within a patchwork of provincial and territorial healthcare policies across Canada. While Ontario and Prince Edward Island lowered their publicly funded colorectal cancer screening thresholds to age 45, most other jurisdictions retained an age-50 cutoff. Following inquiries by media outlets, provincial health authorities have been slow to universally lower these thresholds, though British Columbia agreed to re-evaluate its clinical guidelines.
This policy friction occurs against a backdrop of worsening epidemiological data. Data published by the Canadian Cancer Society highlighted a stark generational increase in risk. Dr. Anu Ghuman, Dhalla’s treating surgeon, noted that individuals born in 1980 or later face double to two-and-a-half times the risk of developing colorectal cancer before age 50 compared to what their parents faced at the same age.
| Metric | Traditional Screening Guidelines | Early-Onset Patient Reality |
|---|---|---|
| Standard Screening Age | 50 to 45 years (province-dependent) | Often symptomatic before age 40 |
| Diagnostic Delay Factor | Routine denial based on chronological age | Requires self-advocacy or alternative testing |
| Generational Risk Multiplier | Baseline population risk (historical) | 2x to 2.5x higher for birth years 1980+ |
Driven by his clinical experience and the barriers he encountered within the healthcare system, Dhalla engineered a home-use fecal immunochemical test. The device is designed for accessibility, requiring the user to collect micro-samples from six distinct locations within a single stool specimen using a specialized applicator tool. The diagnostic readout mimics familiar consumer diagnostics; a single visible line denotes a negative result, while two lines indicate a positive finding requiring urgent clinical follow-up.
The commercialization and widespread distribution of the device remain contingent on formal regulatory authorization. The kit is currently undergoing review by Health Canada. Meanwhile, Dhalla has used digital platforms and social media channels to discuss his clinical trajectory, maintaining public visibility while awaiting regulatory clearance.
