Colon

When cancercells develop at the lower end of the digestive tract, that is, the colon is known as colorectal cancer or more commonly as colon cancer or bowel cancer. When abnormal cells with uncontrollable growth rates and ability to invade others or spread to other parts, develop in these part of the large intestine, they are called colorectal cancer. It is a rare disease; detected only in one among a million. It is mostly caused due to old age and unhealthy lifestyles, but sometimes it is also caused by genetic disorders at the core. Obesity, smoking and deficiency of physical activity in the routine increase the risk of development too.

In general, tumoursare broadly classified into two categories, the cancerous or malignant type and the noncancerous or benign type. Colon cancer, typically, starts from a benign tumour usually in the form of a polyp and then, over time develops into malignant cancer.

It can be diagnosed by obtaining a sample of the colon via sigmoidoscopy or popularly known as Colonoscopy. Medical imaging is then used to detect places where it has spread and determine its location for further treatment. Screening has proved to be a very useful tool in thedetection and has already saved many lives by early detection of colorectal cancer. Non-steroidal anti-inflammatory drugs like Aspirin reduce the risk, but they are not recommended due to side effects.

But the best way to detect colon cancer is to watch out for the essential symptoms. Depending on the extent of the disease, that is, the location and the spread of it, the symptoms differ. But the most classic symptoms are blood in stool, loss of appetite, loss of weight, nausea, etc. Worsening constipation, adecrease in stool caliber (thickness) and change in bowel habit are also signs of colorectal cancer.
