There is no good or bad cure for colon cancer and rectal cancer. Colon cancer and rectal cancer are both malignant tumors, which can be categorized as colorectal cancer, and whether they can be cured or not mainly depends on factors such as how the cancers are treated, whether there are metastases, and whether they are treated early or not. If colon cancer or rectal cancer belongs to carcinoma in situ, it is recommended that patients undergo relevant surgical radical resection treatment, and the prognosis after surgery is better. If colon cancer or rectal cancer patients already have local metastasis or distant lymphatic or systemic metastasis, the efficacy of the treatment is poorer. The five-year survival rate of colon cancer and rectal cancer patients in early stage after treatment can reach 90%, and the five-year survival rate of locally progressed stage 2~3 colon cancer patients after treatment is 50%~78%, so the survival rate of patients with early treatment is also higher. Colon cancer and rectal cancer patients may have abdominal pain, blood in stool, etc. If these situations occur, it is recommended that patients should seek medical treatment as early as possible for relevant examinations and treatments, so as not to delay the condition.
