It depends. The later you find out, the less time you have left. Rectal cancer is an intestinal disease. Because the intestine is the main organ to absorb and digest nutrients, patients will have abdominal pain after cancer. Therefore, for people in life, once abdominal pain occurs, it is time to go to the hospital for treatment. Rectal cancer is a serious threat to people's life and health, especially now that the diet is irregular, it is easy for more and more people to get cancer. After getting sick, some people can live for three months, some people can live for six months, and some people can live 1 year.

Patients with rectal cancer can be treated by routine standard medical care, and most patients will have a better response after surgery. However, it should be noted that intestinal diseases are relatively hidden, such as some symptoms, such as abdominal pain, diarrhea, constipation and so on. Most people don't care about this, but once it develops to the advanced stage, it is a very deadly cancer.

Moreover, if it is a patient with advanced intestinal cancer, the disease develops rapidly and can cause extensive metastasis, such as lung metastasis and bone metastasis. Even if you pass regular surgery, you need to check it regularly to ensure your health. Relatively speaking, the five-year survival rate of some patients is 60%-70%.

The high incidence of colorectal cancer is related to poor gastrointestinal digestion. The absolute number of people over 40 years old is more, and the number of people under 30 years old is less, accounting for only 15%. Nowadays, the incidence of colorectal cancer is second only to gastric cancer and esophageal cancer, and it also needs active prevention in the treatment of colorectal cancer. For people today, most rectal cancers are still related to a diet high in fat, calories and fiber.

Because there are huge intestinal flora in human intestine, high-fat diet will not only stimulate bile secretion, but also promote the growth of some anaerobic bacteria in intestine, which will make some anaerobic bacteria proliferate and grow continuously, thus causing the imbalance of intestinal flora.

Cancer patients also have a genetic factor. There is a susceptibility gene in the human body of cancer patients, which, together with some stimulating factors, promotes the rapid growth of tissue cells and eventually develops into cancer.
