Why does colorectal cancer metastasize

It is very common for colorectal cancer to metastasize in the late stage, and it is also a hot topic for many patients' families to consult. One of the important factors for colorectal cancer metastasis is that it is not treated in time or the original treatment plan is not thorough. At this time, you should find a regular tumor treatment hospital and regular experts to conduct systematic and comprehensive examinations, diagnosis and treatment.

Why does colorectal cancer metastasize in the late stage?

This is related to the characteristics of cancer cells. Not only rectal cancer, but other types of primary tumors may metastasize in the late stage because there are many ways for cancer to metastasize, especially lymphatic metastasis, blood metastasis and implantation metastasis.

The liver is the most common metastatic site of advanced colorectal cancer. About 50% of colorectal cancer patients have liver metastasis, which is an important factor leading to poor prognosis of colorectal cancer patients. However, when liver metastasis is found in the early stage of colorectal cancer patients, only 15% of patients have the opportunity for surgical resection, and the vast majority (about 10%) of patients cannot obtain radical resection, and the long-term survival rate is low. The median survival time of patients with unresectable liver metastasis is less than two years, while patients with complete resection of liver metastases can benefit in the long term, with 3-year and 5-year survival rates reaching 44% and 30% respectively.

What should I do if colorectal cancer metastasizes in the late stage?

In the late stage, colorectal cancer is very likely to metastasize, and may appear in different organs and cause corresponding symptoms, often causing great pain to patients, and even threatening their lives. For patients in the late stage, surgery is not very meaningful, and Western medicine can use radiotherapy and chemotherapy, but no matter which treatment is used, it will bring great side effects to patients.

Experts suggest that the metastasis of colorectal cancer in the late stage does not mean a death sentence. In fact, as long as the right treatment method and hospital are selected, overtreatment is avoided, and the patient's survival period is extended, it is entirely possible to live with the tumor for a long time.
