According to the reports published by the World Health Organisation (WHO), colon cancer is the third most common type of cancer and the leading cause of death. Previously, colon cancer was primarily considered a disease of the elderly, with most diagnoses occurring after the age of 50. Though it remains prevalent in older adults, there is a recent increase in colon cancer cases among the younger generation.
Colon cancer surgery is one of the most effective when it comes to treating the disease, particularly in the early to mid stages. Moreover, there are other approaches like chemotherapy, radiation therapy and targeted drugs which are employed depending on the stage of the cancer.
In this blog, we will discuss what patients should know about the procedure, including what it involves, when it is recommended, types, recovery, possible risks and outcomes.
Take a look below at some of the critical facts related to colon cancer surgery.
Colon cancer surgery is a procedure aimed at killing or removing the cancerous cells or tumour from the affected colon. As stated, the method is either performed as a single treatment or in combination with other therapies. The main objective is to eliminate further growth of cancer cells and prevent their spread.
For most patients, surgical intervention is recommended for colon cancer under the following circumstances.
The type of colon cancer surgery which a surgeon recommends depends on factors such as the location of the tumour, its stage and the overall health of the patient. Some of the common approaches include.
Polypectomy and Local Excision: It is usually carried out in early-stage cases when the cancer is confined to a polyp.
Colectomy (Colon Resection): It is a procedure that involves removing part or all of the colon to kill the cancer cells along with some portion of healthy tissues.
Laparoscopic Surgery: It is a minimally invasive technique where small incisions are made to remove the cancerous part of the colon and lymph nodes.
Open Surgery: It is a conventional method that requires making a larger incision and is typically performed when the tumour is large or hard to reach.
Colostomy: When reconnecting the remaining parts of the colon is not possible, a colostomy may be performed. This diverts the bowel to an opening in the abdomen, where waste is collected in a bag.

When the cancer cells from the colon are not removed during the early or treatable stage, they multiply and spread to the lymph nodes and other parts of the body. As a result, the malignant tumour reaches the advanced phase where a cure becomes difficult. Unnecessary postponement of colon cancer surgery greatly impacts the outcomes and reduces the survival rates.
Recovery timeline after a colon cancer surgery depends upon its type and the patient’s individual health. If it’s an open procedure, the healing period might take around a few months. Moreover, patients might face some post-operative discomfort. However, in the case of minimally invasive techniques, the healing time is just a few weeks with no such complications.
Before colon cancer surgery, patients are required to undergo a series of diagnostic procedures, such as the following:
To ensure a successful procedure, patients are advised to follow these instructions.
Following the surgery, make sure to follow all the post-operative guidelines for a safe and quick recovery.
Just like any surgical intervention, colon cancer surgery also comes with certain risks. Though rare, complications happen when it is performed by an inexperienced surgeon.
The success rate after colon cancer surgery depends on its stage.
Stages I and II: It is often curable with a high survival rate.
Stage III: Requires surgery along with chemotherapy to increase the survival rate
Stage IV: Surgery is palliative with other treatment approaches.
The five-year survival rate usually decreases with each stage. Hence, make sure to opt for early screening and treatment for permanent relief.
With advancements in medical technology, the outcome of colon cancer surgery is improving. If you or someone you know is diagnosed with the disease, always consult a skilled surgeon like Dr. Purnendu Bhowmik for a thorough evaluation and personalised approach for the best results.
