Cancer can significantly impact the digestive system, depending on the type of cancer and its location. For instance, cancers of the gastrointestinal tract, such as gastric or colorectal cancer, can directly interfere with digestion. These cancers may cause blockages, bleeding, or alter normal bowel movements. Even cancers that do not originate in the digestive system, like pancreatic cancer, can influence digestion by affecting enzyme production, which is essential for breaking down food.
