Association of occupational heat exposure and colorectal cancer in the MCC-Spain study.

Objective: Heat exposure and heat stress/strain is a concern for many workers. There is increasing interest in potential chronic health effects of occupational heat exposure, including cancer risk. We examined potential associations of occupational heat exposure and colorectal cancer (CRC) risk in a large Spanish multi-case--control study.

Differences in breast cancer-risk factors between screen-detected and non-screen-detected cases (MCC-Spain study).

Purpose: The variation in breast cancer (BC)-risk factor associations between screen-detected (SD) and non-screen-detected (NSD) tumors has been poorly studied, despite the interest of this aspect in risk assessment and prevention. This study analyzes the differences in breast cancer-risk factor associations according to detection method and tumor phenotype in Spanish women aged between 50 and 69.

Methods: We examined 900 BC cases and 896 controls aged between 50 and 69, recruited in the multicase-control MCC-Spain study.

Impact of the COVID-19 pandemic during Spain's state of emergency on the diagnosis of colorectal cancer.

Introduction: We evaluate the impact of COVID-epidemic in colorectal cancer (CRC) diagnosis during Spain's state of emergency.

Methods: We compared newly diagnosed patients with patients diagnosed in the same period of 2019.

Results: A new diagnosis of CRC decreased 48% with a higher rate of patients diagnosed in the emergency setting (12.

Dietary Inflammatory Index, Dietary Non-Enzymatic Antioxidant Capacity, and Colorectal and Breast Cancer Risk (MCC-Spain Study).

Inflammation and antioxidant capacity have been associated with colorectal and breast cancer. We computed the dietary inflammatory index (DII), and the total dietary non-enzymatic antioxidant capacity (NEAC) and associated them with colorectal and breast cancer risk in the population-based multi case-control study in Spain (MCC-Spain). We included 1852 colorectal cancer and 1567 breast cancer cases, and 3447 and 1486 population controls, respectively.
