The majority of colorectal cancers begin with a tumour on the inner lining of the colon or rectum. These growths are known as polyps. Polyps are rather frequent, particularly as you get older. Most polyps are benign, which means they are not malignant. Some polyps can develop into cancer over time (often over many years). The likelihood of a polyp developing into cancer varies according to its type. There are several forms of polyps. Colon and rectal cancer are sometimes classified together since they share similar characteristics. If cancer develops in a polyp, it can eventually spread to the colon or rectal wall. The colon and rectal walls are made up of many layers. Colorectal cancer begins in the innermost layer (mucosa) and spreads to some or all of the other layers.
The primary treatment available for removing cancerous tumours in the colon or rectum is Colorectal Cancer Surgery. Colorectal cancer surgery in Bhubaneswar involves removing the tumour along with a margin of healthy tissue, often accompanied by the removal of nearby lymph nodes to check for cancer spread. There are various other surgical approaches available depending on the cancer's location and stage. These include open surgery, minimally invasive techniques like laparoscopic and robotic surgery, and others. Generally, for more advanced cancers, a Partial or Total Colectomy is suggested, which involves removing a section or the entirety of the colon. But, after the surgery, some patients also require additional treatments such as Chemotherapy or Radiation to reduce the risk of recurrence.

The specific causes of colorectal cancer are unknown; however, it appears to be caused by both genetic and lifestyle factors.
Lifestyle factors such as cigarette smoking, a lack of physical activity, and obesity may raise the risk of acquiring the condition. Genetic factors may define a person's vulnerability to the disease, whereas dietary and other lifestyle factors may influence which at-risk individuals develop the disease.
Most of the time, there is no clear cause for the development of colorectal cancer in any given individual, and it is just the result of random genetic alterations in the cells lining the colon or rectum.
In the most common procedures—Colectomy for colon cancer and Proctectomy for rectal cancer—the diseased piece of the colon or rectum is removed and the two healthy ends are rejoined. In some cases, rejoining the ends is not safe at the moment, so the surgeon links the colon to an incision created in the belly, a technique known as a colostomy, where a bag is attached. Stool travels from the colon to the abdomen before being collected in a plastic bag or pouch worn on the exterior of the body. This diversion may be temporary and then rectified at a later time.
Following are the Colorectal Cancer Surgery options:
Your recovery period following surgery will be determined by your age, whether you underwent open or keyhole surgery, whether you have a stoma, and your overall health. You will most likely spend 2–7 days in the hospital, although full recovery might take up to 2–3 months.
Patients can resume their normal diet. A Colectomy rarely has any long-term repercussions on bowel patterns. A frequent misunderstanding about colon cancer is that patients will need an ostomy bag following surgery. However, this only applies to people who have had a Colostomy.
Start by walking a little further than you did the day before. Gradually increase the amount you walk. Walking increases blood flow and helps avoid pneumonia and constipation.
Avoid intense activities like biking, jogging, weight lifting, or aerobic exercise until your doctor says it's safe.
Colon cancer is a highly treatable and frequently curable disease when it affects only the gut. Surgery is the major mode of treatment, and it cures around 50% of patients. However, recurrence after surgery is a big issue and is frequently the last cause of mortality.
Colorectal surgical procedures typically last two to three hours, although they may take longer depending on the circumstances, type of technique used, and your overall health. Your doctor can advise you on this during your appointment before the surgery.
One of the most common complications after surgery is that your bowels may shut down. It's termed an ileus. This indicates that food and gas have difficulty travelling through your intestines. If you get ileus, it typically lasts two to three days.
Possible complications from Bowel Cancer surgery include a leak where the surgeon has connected the ends of your colon together and your gut is not working properly. Infection, blood clots, and bleeding are also possible dangers. Many problems are minor, but some are life-threatening. Treating them as soon as possible is critical.
The waste material (poo) is then retained in the back tube (rectum) until it is passed out of the body via the anus. Your bowel movements may be looser and more frequent immediately following Colon surgery.
