If a person stops using anthranoid laxatives, the changes associated with melanosis coli lessen over time and may disappear.
Early studies suggested that anthranoid laxatives might have carcinogenic or tumor-promoting activities in humans and that the presence of melanosis coli might signal an increased risk for the development of colorectal cancer.
