According to a recent publication in journal Cancer increased intake of processed meat has been linked to increased risk of bladder cancer.
Potentially carcinogenic meat-related compounds related to cooking and processing which have been thought of increasing the risk include nitrate, nitrite, heterocyclic amines (HCAs), and polycyclic aromatic hydrocarbons (PAHs)
These findings provided modest support for an increased risk of bladder cancer with total dietary nitrite and nitrate plus nitrite from processed meat.
The Results also suggested a positive association between red meat bladder carcinogenesis.
