What are three cancers caused by dioxin?

Respiratory cancers (lung, bronchus, trachea, larynx) Prostate cancer. Multiple myeloma. Bladder cancer.

Does dioxin cause colon cancer?

Dioxin subtly changes cell DNA. These changes lead to a wide array of serious health problems. These genetic changes can certainly cause colon cancer.

What foods are high in dioxin?

Fatty foods such as meat, poultry, seafood, milk, egg and their products are the major dietary sources of dioxins. Accidental exposure to large amount of dioxins could lead to the development of chloracne, a skin condition, excessive body hair and other skin lesions such as skin rashes and skin discolouration.
