Generally speaking, it is possible to have a normal diet one month after having colon cancer surgery. However, light and easy-to-digest food should be the main focus, and balanced nutrition should be ensured at the same time. Generally speaking, after colon cancer surgery, it takes about 2~3 weeks to gradually transition from liquid diet to normal diet, so it is possible to have normal diet about one month after surgery. Due to the large consumption of cancer surgery, some patients may suffer from malnutrition, so they should pay attention to the matching of diet, and it is recommended to choose protein-rich and easy-to-digest food such as milk and egg custard for consumption. Meanwhile, fresh fruits and vegetables can be chosen for vitamin intake. However, it is not recommended to consume deep-fried, spicy and stimulating foods after colon cancer surgery, especially fried chicken, French fries, chili peppers and peppercorns, so as not to stimulate the gastrointestinal tract.
