Lifestyle risk factors for cervical glandular and squamous cell neoplasia: insights from a prospective cohort study of over 117,000 women

Abstract Background While cervical cancer screening has successfully reduced squamous cell carcinoma (SCC) rates, adenocarcinoma (AC) incidence is rising, particularly among younger women. Although SCC and AC differ in genomics and treatment responses, evidence regarding their di...

Does active surveillance prior to radical prostatectomy increase the risk of adverse pathological findings or postoperative prostate cancer treatment?

Active surveillance (AS) is an established management strategy for men with low- and favorable intermediate-risk prostate cancer (PCa). Nevertheless, a substantial proportion of patients ultimately undergo radical prostatectomy (RP), and the impact of prior AS on subsequent outco...

Gut microbiome signatures of colorectal cancer development are more pronounced in women compared to men in a population-based screening cohort

Abstract Background The gut microbiome has emerged as a promising source of biomarkers to enhance early detection of colorectal cancer (CRC). However, sex-specific differences in gut microbial profiles and their relationship to CRC risk remain underexplored. Our objective was to...

Trends in early-onset cancer incidence rates in the Nordic countries (2003–2022): a population-based study

Background Increasing incidence rates of early-onset cancer at ages 20–49 years have been reported in several countries, especially for colorectal, kidney and breast cancer. We examined recent incidence trends of early-onset cancer in Denmark, Finland, Iceland, Norway, Sweden, Gr...

High-grade serous ovarian cancer is associated with increased TP53 mutation burden in uterine lavage

High grade serous ovarian cancer (HGSC) has low survival partly due to the lack of methods for detection, diagnosis, and risk prediction. TP53 mutations, which drive HGSC, are found in gynecological tissues as the result of somatic evolution, but it is unknown whether an excess o...

Prospective analysis of pre-diagnostic untargeted plasma metabolomics and risk of triple-negative breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Triple-negative breast cancer (TNBC) accounts for 10–15% of newly diagnosed breast cancer, and its aetiology is poorly understood compared to other breast cancer subtypes. We applied untargeted metabolomics to identify novel biological pathways associated with TNBC risk and poten...

Nut consumption and the risk of hypertension: a systematic review and dose response meta-analysis of prospective studies

Abstract Previous studies have suggested that a high intake of nuts may reduce the risk of hypertension, however, the available data have been limited. Several additional studies have recently been published on the topic. We therefore conducted a systematic review and meta-analys...
