Symptoms & Causes Of Colorectal Cancer


Colorectal cancer, also referred to as colon cancer, is a combination of colon and rectal cancer. This means that cancer that develops in the colon is known as colon cancer, while cancer that occurs in the rectum is known as rectal cancer. However, cancer that affects either of these organs is known as colorectal cancer. It usually develops in the large intestine, where your body draws water and salt from solid wastes, then moves through the rectum to exit the body through the anus. It is one of the most common types of cancer and cause of death in India and worldwide among men and women.

Colorectal is the third most common cancer among men and is among the top 5 most frequent cases reported today. To know of its symptoms and how it occurs, continue reading.

What are the symptoms?

It can be difficult to identify symptoms of colorectal cancer, as there are chances it can develop without any sign or symptom. You will often not notice any symptoms in the early stages but only start observing symptoms as cancer progresses. However, if you do experience symptoms in the early stages of colorectal cancer, they might include:

  • Constipation
  • Change in stool color
  • Diarrhea
  • Blood in stool
  • Excessive gas
  • Abdominal pain & cramps
  • Bleeding from the rectum

If you experience any of these symptoms, consult a doctor immediately and don’t wait for the symptoms to get worse.

In the later stages, you will get more noticeable symptoms like:

  • Weakness
  • Excessive fatigue
  • Vomiting
  • Unexplained weight loss
  • A feeling of bowels not being empty

What are the causes?

There are no significant causes of colorectal cancer. Still, experts say colorectal cancer occurs when cells grow and divide uncontrollably and don’t die at the end of their usual life cycle. They are usually damaged and become cancerous. They continue to divide into new cells even when they are not needed. These cells get accumulated over a period and form a tumor. These cancerous cells may spread throughout the body and invade the healthy tissues known as Metastasis.

The exact cause of colorectal cancer is still unknown, but various risk factors might increase the chances of developing it. Some of which are:

  1. Old age
  2. Underlying conditions
  3. Regular alcohol intake
  4. Overweight
  5. Smoking
  6. Sedentary lifestyle
  7. A history of bowel disease
  8. A family history of colorectal cancer
