Cancer that starts in the rectum (the last few inches of the large intestine) is known as rectal cancer. It begins at the end of your colon’s final segment and ends when it enters the anus’s short, narrow passage. The cancers of the rectum (rectal cancer) and the colon (colon cancer) are often referred to as ‘colorectal cancer’, says Dr. Sanjoy Mandal, who is considered to be one of the best cancer surgeons in Kolkata.
In certain ways, rectal and colon cancers are identical, but their therapies are vastly different. This is due to the fact that the rectum occupies a small area, scarcely distinguishable from other organs and structures. Surgical removal of rectal cancer can be complex due to the limited space.
Symptoms and Warning Signs
The following are some of the warning signs and symptoms of rectal cancer, as listed by the cancer doctor in Kolkata:
- Diarrhoea, constipation, or change in bowel habits
- Blood in stool that is dark maroon or bright red
- Feeling as if your bowels aren’t emptying completely
- Narrow stool
- Pain in the abdomen
- Unexplained weight loss
- Weakness or exhaustion
Causes Of Rectal Cancer
Rectal cancer is caused by changes (mutations) in the DNA of healthy cells in the rectum. The instructions that tell a cell what to do are contained in the DNA of that cell.
The changes instruct the cells to expand uncontrollably and to live after healthy cells have died. A tumour may develop from the accumulating cells. Cancer cells may develop large enough to infiltrate and kill healthy tissue in the surrounding area over time.
It’s unclear what causes the mutations that cause rectal cancer to develop in most cases.
Rectal Cancer Treatment in Kolkata

With compassionate, personalised treatment from our experts, we want to help you reclaim control of your life.

A combination of different treatment modalities is also the most successful way to treat rectal cancer. Dr. Sanjoy Mandal will create a treatment plan that is exclusive to you. The size and location of the tumour, as well as whether the cancer has spread to the lymph nodes or other organs, will all influence how the oncology surgeon in Kolkata treats you.
For certain stages of rectal cancer, surgery is the most common treatment option. To shrink the tumour, Dr. Mandal can combine it with other treatments, including radiation and chemotherapy. He may use one of the several treatment options, including:
- Total neoadjuvant therapy, a precise combination of chemotherapy and radiation therapy, renders tumours as small as possible before surgery.
- Surgery might not be the best choice if the rectal cancer has spread. Chemotherapy, which is often combined with radiation therapy, allows the oncology specialist in Kolkata to start treatment immediately throughout your entire body.
