Colon cancer is the third most common cancer in India. It starts in the large intestine or rectum, the lower portions of your digestive tract.

We have discussed the symptoms, causes, and treatment for colon cancer on this page.
Let’s start with the overview of colon cancer
Colon cancer, which occurs in the large intestine, is more common in older people, although it can strike anyone at any age. It usually starts as polyps, which are tiny, noncancerous (benign) clusters of cells that grow inside the colon. Some of these polyps can turn into colon cancer over time.
Small polyps may create few, if any, symptoms. As a result, Dr. Sandeep Nayak, a cancer specialist in Bangalore, recommends routine screening tests to help prevent colon cancer by detecting and removing polyps before they turn cancerous.
If colon cancer develops, various treatments, including surgery, radiation therapy, and medication such as chemotherapy, immunotherapy, and targeted therapy, are available to help manage it.
What are the symptoms of colon cancer?
The following are some of the symptoms and signs of colon cancer:
- Blood in your feces or rectal bleeding
- A change in your bowel habits, like diarrhea, constipation, or a change in the consistency of your feces.
- Constant gastrointestinal discomfort, such as cramps, pain, or gas.
- Feel as if your bowels aren't totally empty
- Weakness or tiredness
- Sudden weight loss
Many patients show no signs or symptoms in the early stages of colon cancer. Symptoms will vary depending on the size and location of cancer in your large intestine.
Make an appointment with Dr. Sandeep Nayak, one of the best oncologist in Bangalore, India, if you detect any persistent symptoms that concern you.
What are the causes of colon cancer?
Doctors are still unsure regarding the cause of colon cancer. Generally, colon cancer develops when the DNA of healthy colon cells undergoes mutations.
When a cell's DNA is disrupted, it becomes malignant, and the cell continues to divide even though new cells aren't required. As the cells multiply, a tumor develops.
Cancer cells can grow large enough to penetrate and destroy normal tissue nearby over time. Furthermore, malignant cells can migrate to other places of the body and metastasis.
How is colon cancer diagnosed?
If you have signs and symptoms that point to colon cancer, Dr. Sandeep Nayak, one of the best oncologist in Bangalore, India, may suggest one or more tests, such as:
- Blood tests
- Fecal testing
- CT scan
Following diagnosis, Dr. Sandeep Nayak will assess the cancer stage based on the tumor's size, extent, and spread to neighboring lymph nodes and distant organs.
The stage of cancer will impact the treatment options and prognosis.
Colon cancer treatment in Bangalore, India
Colon cancer treatment is dependent on several factors. Based on your overall health and the stage of your colon cancer, Dr. Sandeep Nayak, a renowned cancer specialist in Bangalore, will decide the best treatment plan for you.
Colon cancer treatment in Bangalore, India, includes surgery, chemotherapy, and radiation.
The goal of treatment is to eliminate cancer, prevent it from spreading, and relieve any unpleasant symptoms.
Surgery for early-stage colon cancer
Polypectomy: Dr. Sandeep Nayak can remove your cancer during a colonoscopy if it is in an early stage, localized, small, and completely contained within a polyp.
Endoscopic mucosal resection: The surgical oncologist will remove larger polyps during a colonoscopy with special equipment that removes the polyp as well as a small portion of the colon's inner lining.
Laparoscopic surgery: Laparoscopic surgery can be used to remove polyps that can't be eliminated during a colonoscopy. Dr. Sandeep Nayak, one of the best oncologist in India, is considered a pioneer in laparoscopic surgery.
Surgery for advanced colon cancer
Total abdominal colectomy: In this procedure, the surgical oncologist will remove the entire large intestine from the lower region of the small intestine to the rectum. Then he will stitch the small intestine to the rectum. It can be done either through laparoscopy or as open surgery.
Proctosigmoidectomy: In this minimally invasive surgery, Dr. Sandeep Nayak, an experienced surgical oncologist in India, only removes the affected section of the rectum and the sigmoid colon.
Abdominoperineal resection: In this surgical treatment, the anus, rectum, and sigmoid colon are removed. As a result, a permanent colostomy (an artificial bag) is placed so that the patient can pass out their waste.
Right colectomy: Here, the surgeon will remove the right side of the colon. He will also remove the last portion of the small intestine attached to the colon on the right side.
Total proctocolectomy: This procedure involves the removal of the colon, anus, and rectum.
In chemotherapy, the oncologist will use medications to kill cancer cells. After surgery, it is generally provided for persons with colon cancer to remove any remaining malignant cells. Chemotherapy can help slow the progression of cancers.
Radiation delivers an intense beam of energy similar to that used in X-rays to target and destroy malignant cells. Radiation therapy is frequently used in conjunction with chemotherapy.
Apart from the above treatments, Dr. Sandeep Nayak, one of the best oncologist in Bangalore, India, may recommend immunotherapies and targeted therapies. They help treat late-stage or metastatic colon cancer that hasn't responded to earlier treatments.
