Burden of Colorectal Cancer Mortality in Grenada: A Retrospective Observational Study from 2014 to 2023
This retrospective study of colorectal cancer mortality in Grenada from 2014 to 2023 found no significant temporal trends or sex-based disparities, but identified a strong association between increasing age (particularly 60–89 years) and higher death rates, highlighting the urgent need for targeted screening and early diagnosis in older populations.

Colorectal cancer, a disease that begins in the colon or rectum, stands as a leading cause of death from cancer around the world. It is a condition that does not strike randomly; it is deeply tied to the passage of time, becoming far more common as people grow older. While modern medicine has made great strides in finding and treating this disease in wealthier nations, the picture is often different in other parts of the world, where access to early detection can be limited. In these regions, the disease often goes unnoticed until it is advanced, making it harder to treat. Understanding how this disease affects specific communities is vital for public health officials who must decide where to direct resources and how to save lives. The question is not just about how many people are dying, but who is dying, when, and whether the situation is getting better or worse over time.
In the small island nation of Grenada, a team of researchers set out to answer these questions by looking back at a decade of records. They gathered data on every death caused by colorectal cancer in the country from 2014 through 2023. Their goal was to see if the number of deaths was rising or falling, and to understand if age or gender played a major role in who was most at risk. By examining these ten years of history, they hoped to provide a clear picture of the burden this disease places on the island, offering evidence that could help local health leaders plan for the future.
The researchers found that over the course of the study, 150 people in Grenada died from colorectal cancer. When they looked closely at the numbers, they discovered that the risk of dying from this disease was not evenly distributed across the population. Instead, age was the most powerful factor. Deaths were rare among people under the age of forty. However, once people passed the age of fifty, the risk began to climb sharply. The highest number of deaths occurred in people between the ages of sixty and sixty-nine, with the risk remaining very high for those in their seventies and eighties. In fact, nearly three-quarters of all the deaths recorded happened in people over the age of sixty. This pattern confirms what is seen in many other places: this disease is primarily a threat to older adults.
Surprisingly, the study found that being a man or a woman did not significantly change the likelihood of dying from colorectal cancer in Grenada. While global statistics often show higher death rates for men, the data from this island nation showed a nearly equal split between the sexes. The researchers noted that this might be because both men and women in Grenada face similar lifestyle risks, or perhaps because the lack of a national screening program means that people of both genders are often diagnosed too late to save them. Without a systematic way to catch the disease early, the outcome remains similar regardless of gender.
When the team looked at the trend over the ten-year period, they did not see a clear rise or fall in the number of deaths. The rate of mortality fluctuated from year to year, with some years seeing more deaths and others seeing fewer, but the overall direction was flat. The data did not support the idea that the situation was improving, nor did it show a dramatic worsening. This stability is notable because, in many high-income countries, death rates from this cancer have been going down thanks to better screening and treatment. In Grenada, the absence of a downward trend suggests that the island has not yet seen the same benefits from early detection programs that have helped other nations.
The researchers acknowledge that the small size of Grenada's population makes these numbers swing more wildly from year to year than they would in a larger country. A few extra deaths in a single year can change the statistics significantly. Despite this variability, the core message of the study is clear: the disease is a serious threat to older Grenadians, and the current system is not yet reducing the number of deaths. The study points to a critical need for better screening, particularly for those over fifty, to catch the disease before it becomes fatal. Without these interventions, the pattern of mortality is likely to remain unchanged, leaving the population vulnerable to a preventable tragedy.
