In rectal cancer, the cells in the rectum’s lining become malignant and grow out of control. The rectum is located at the end of the large intestine and right before the anus. It’s estimated that about 1 in 23 men and 1 in 25 women are at risk of rectal cancer.
Adenocarcinoma is the most common type of rectal cancer. It begins in the epithelium lining that makes the mucus in either the colon or the rectum. Both rectal cancer and colon cancer can be referred to as colorectal cancer.
Most colorectal cancers originate from precancerous polys, which gradually become large and cancerous. However, it allows for early detection and treatment before the cells become malignant.
In the early stages, rectal cancers don’t cause any symptoms. When symptoms do appear, they may include:
If anyone has these symptoms for more than a week, they should consult with an oncologist for rectal cancer screening.
Rectal cancer is caused when healthy cells in the rectum start mutating and forming polyps. Over time, these malignant cells begin to destroy the healthy cells and spread to other parts of the body.
While the exact causes of rectal cancer are unknown, various factors can increase the risk. These factors are:
Our doctors will evaluate the patient’s symptoms and medical history for the signs of rectal cancer. If rectal cancer is suspected, they will perform a physical examination and screening tests for further diagnosis, which may include:
Based on the test results and how far cancer has spread, our doctor may categorize cancer from stage 0 to 4:
Treatment for rectal cancer often requires a combination of therapies. Based on the cancer stage, possible complications and the patient’s preference, our doctors will recommend the most-effective treatment option for rectal cancer, which include:
It’s the most common treatment option in which our surgeon will surgically remove the tumour and the surrounding tissues through various approaches, which are:
In chemotherapy, our doctors will use a group of drugs to stop cancer from spreading. Cancer cells absorb the drugs faster than normal cells, thus slowing their growth. These drugs can be delivered through a vein or a catheter, depending on the stage of cancer.
Our surgeon will use controlled radiation to damage or destroy the DNA of cancer cells. Our radiation oncologist will use a machine to direct the energy beams on the cancer cells. It can be used in combination with chemotherapy if surgery isn’t an option.
