Diagnosis and treatment of colorectal cancer

Many patients with colorectal cancer are worried about how to treat colorectal cancer, whether it will be harmful to the body, and whether there will be sequelae. Many patients pay the hospital and let the hospital treat them, and they do not know the information about colorectal cancer treatment. So, according to the patient's wishes, let the experts tell us how colorectal cancer should be treated.

Surgical treatment is a very common method, which mainly achieves the purpose of cure by resection. This method is often accompanied by erosion, bleeding or secondary infection of the tumor. After resection, the general condition can be improved. For patients with extensive cancer metastasis, if the diseased intestinal segment can no longer be removed, palliative surgery such as fistula or shortcut should be performed.

Chemotherapy and surgery sometimes may not necessarily cure the patient, so chemotherapy comes into play at this time. Before surgical resection, systemic chemotherapy or intra-intestinal chemotherapy can be performed first to prevent the spread of cancer cells, kill and eliminate cancer cells. Continuing chemotherapy after surgery may increase the 5-year survival rate after radical surgery.

Radiotherapy. Radiotherapy is divided into multiple time periods, such as preoperative and postoperative. Preoperative radiotherapy can help shrink the tumor, improve the resection rate, reduce regional lymph node metastasis, intraoperative spread of cancer cells and local recurrence. Postoperative radiotherapy is suitable for cases that can be cured by surgery, such as the tumor has penetrated the intestinal wall, invaded local lymph nodes, lymphatic vessels and blood vessels, or there is residual tumor after surgery but there is no distant metastasis.

In summary, there are three main treatments for colorectal cancer: surgery, chemotherapy, and radiotherapy. These treatments will definitely have some impact on the body, but the hospital will definitely minimize this impact. After understanding the treatment of colorectal cancer, readers will feel more at ease about the treatment process, and this will give everyone confidence in the treatment of colorectal cancer.
