red and processed meat and cancer

In 2015, the cancer agency of the World Health Organization, the International Agency for Research on Cancer (IARC), classified the consumption of red meat, which includes beef, lamb, and pork, as carcinogenic to humans if eaten in processed form, and as probably carcinogenic if eaten unprocessed[1].

Risk ratios for red and processed meat and cancer

Pulling extensively from Farvid et al., 2021 which details at the individual cancer level

Han et al., 2019 found small RRs

Wang et al., 2016 found across 3 studies, cancer mortality increase associated with 100g more unprocessed meat (RR = 1·12, 95 % CI 1·07, 1·17; P = 0·001). across 5 studies the risk ratios for cancer mortality associated with 50g per day of processed meat was 1.08 (95% CI 1.06-1.11)
