Colon cancer treatmentStage 1 and 2 colon cancer only require surgery and basically do not require chemotherapy, except for patients with a high risk of recurrence who may undergo several chemotherapy treatments before surgery, which is medically called neoadjuvant chemotherapy.

In the third stage, surgery is also performed, followed by complete adjuvant chemotherapy to ensure that the tumors disappear. In the fourth stage, chemotherapy or targeted therapy will be recommended to shrink the primary tumor and reduce the difficulty of surgery, while also giving the opportunity to Distal metastases were reduced and then removed.

Because 95% of colon cancer is caused by adenomatous polyps, it usually takes more than 10 years for adenomatous polyps to turn into cancer, and it takes another 5 to 10 years to reach stage 4, so usually stage 4 The patients are all older, usually over 60 or 70 years old.

Corresponding genetic testing should be done before using targeted drugs. Only after Only the use of targeted drugs guided by genetic testing results can exert anti-tumor effects.

Some patients may also wonder, if chemotherapy is ineffective and targeted therapy is too expensive, can I use radiotherapy to kill cancer cells?

The healthy normal tissue will slowly recover on its own, but the cancer cells will not, thus eliminating the tumor.

However, there are also small intestine, bladder, and uterus near the colon, and the small intestine in particular is very sensitive to radiation.

If the location of the tumor is too low, it usually has to be removed together with the anus. In the future, stool can only come out from the artificial feces bag on the belly, which causes a lot of psychological pressure on the patient's postoperative life. Therefore, radiation therapy will be combined from the second stage. Let the tumor shrink first before performing surgery. After surgery, chemotherapy will be performed as appropriate to preserve the anus as much as possible.
