This descriptive, cross-sectional study aimed to determine the prevalence of diagnosed cancers, the distribution of cancer types, and the duration of cancer diagnoses among adults with type 2 diabetes mellitus (T2DM) managed in a primary care setting in Türkiye. The analysis also sought to examine clinical and demographic factors linked to cancer findings according to T2DM duration.
The authors frame the investigation within existing epidemiologic concerns that T2DM is associated with increased risk for several malignancies. Shared risk factors and pathophysiological mechanisms described in the abstract include obesity, hyperinsulinemia, chronic inflammation, and other metabolic disturbances that may contribute to cancer risk in people with diabetes.
The research was carried out at an education-family health centre (EFHC) affiliated with Marmara University Tuzla. The study used a descriptive cross-sectional design based on review of medical records complemented by patient interviews. The sample comprised 442 adult patients registered with T2DM at the Marmara University Tuzla EFHC.
Of these 442 patients, 152 had a recorded diagnosis of cancer. The abstract presents the overall cohort size and the number of patients with cancer; additional recruitment, exclusion criteria, and sampling procedures were not reported in the abstract.
Data collection combined medical record review and direct patient interviews. Collected variables reported in the abstract included cancer prevalence and type, sociodemographic characteristics, clinical features such as body mass index (BMI) and T2DM duration, presence of comorbidities, and cancer duration. The abstract does not report specific measurement instruments, questionnaires, or the exact definitions used for clinical variables.
In this primary care T2DM population, the overall prevalence of diagnosed cancer was 34.4% (152 of 442 patients). The most frequently observed cancers were prostate cancer in men and breast cancer in women. The abstract highlights this distribution but does not provide counts or proportions stratified by sex beyond naming the most common sites.
The authors emphasize that the observed cancer prevalence among Turkish patients with T2DM in this primary care setting is notably high, supporting the importance of integrated screening and management of shared risk factors in routine diabetes care.
The study examined associations between the duration of T2DM and the duration of diagnosed cancer. According to the abstract, no significant correlation was observed between T2DM duration and cancer duration across the cohort. The authors additionally reported that breast cancer was less frequent among women with longer T2DM duration compared with their cancer duration; the abstract does not provide numeric values, effect sizes, or statistical test results for these comparisons.
The cohort exhibited a high rate of obesity and multiple comorbid conditions. This elevated burden of obesity and comorbidity is consistent with the conceptual model linking metabolic risk factors to cancer risk among people with T2DM and supports the authors' call for risk-factor management in primary care. Precise proportions for obesity and individual comorbidities are not reported in the abstract.
The authors interpret the high cancer prevalence among T2DM patients in this primary care sample as evidence that routine diabetes management should incorporate cancer prevention and early-detection strategies. They recommend integrated screening and targeted preventive approaches and emphasize personalized care to reduce cancer-related morbidity and mortality among people with diabetes.
These implications rest on the observed predominance of prostate and breast cancers and the high background rates of obesity and comorbidity in the cohort.
The abstract provides core findings but omits several methodological and result details that would be needed for full critical appraisal. Specifically, the abstract does not report:

In a primary care population of 442 adults with type 2 diabetes mellitus registered at a Turkish EFHC, 34.4% had a diagnosed cancer; prostate and breast cancer were the most common cancers by sex. No overall correlation between diabetes duration and cancer duration was found, though the abstract reports a lower frequency of breast cancer among women with longer diabetes duration relative to cancer duration. The cohort had high rates of obesity and comorbidity. The authors conclude that integrated screening and risk-factor management in primary care are needed to address elevated cancer burden in people with T2DM.
