Is long-term dull pain in the left abdomen a manifestation of cancer in its early stages?

Long-term dull pain in the left abdomen is an early manifestation of cancer, but it does not mean that it is caused by cancer.

Cancer is formed by mutations in the body's cell tissues caused by adverse factors. When kidney cancer, colorectal cancer and other diseases occur, cancer cells infiltrate local normal tissues, and symptoms of long-term dull pain will occur. However, benign diseases such as nephritis, pancreatitis and enteritis can also cause long-term dull pain in the left abdomen, so it does not necessarily mean that it is caused by cancer.

Patients can observe the borderless space-occupying lesions in the left abdomen through imaging examination, and if necessary, can be further diagnosed through pathological examination to determine whether it is cancer.
