Is constant farting an early symptom of rectal cancer?

Rectal cancer may occur in the early stages of the symptoms of non-stop farting, but non-stop farting is not necessarily a manifestation of rectal cancer. If you often eat some foods that are easy to produce gas, such as radish, onion, sweet potato, corn, etc., eating such foods will lead to an increase in gas in the intestinal tract, resulting in non-stop farting. In addition, if the eating habits are not good, such as overeating or talking while eating, it is easy to swallow a lot of gas, and then the above symptoms occur. However, if this symptom has not been improved after adjusting the diet structure or changing eating habits, it is necessary to be alert to rectal cancer, and should go to the hospital in time for relevant examinations to confirm diagnosis and treatment.
