Here are the 5 most common myths about colorectal cancer.
Colorectal cancer is a type of cancer that occurs in the colon or rectum, and is often referred to as bowel cancer.
Colorectal cancer which is gaining widespread importance these days globally, ranks third as the most common cancer in India. Social stigma and people’s ignorance towards the symptoms of the disease delays diagnosis. Here are the 5 most common myths about colorectal cancer. Dr. Rajeev Premnath, General Laparoscopic Surgeon and Endoscopist specializing in Minimally Invasive Proctology, Ramakrishna Super Speciality Hospital, Bengaluru dispels myths about colorectal cancer:
Myth 1: It’s an old age disease
Fact: Gone are the days when colon cancer was limited to old age. Its impact is felt across diverse age groups and demographics. Recent studies have made it more common among younger groups aged 20 to 49. Some reasons for the spike include: diet, obesity, habits and genetics.
Myth 2: Colorectal cancer is hereditary
Fact: Although familial/genetic/hereditary conditions increase the chances of getting colorectal cancer by 10-20% due to gene abnormality. But, 75% are sporadic.
Myth 3: Colorectal cancer is not preventable.
Fact: NO! Colorectal cancer can be prevented. Proper habits, avoiding alcohol and nicotine in all forms and regular exercise complemented by a rich vegetarian diet can prevent colorectal cancer. Maintaining a normal BMI range helps.
Regular screening is important in people who are predisposed. Since precancerous polyps on the lining of the colon and rectum, are often the precursors of colorectal cancer, proper screening can assist in identifying and removing these polyps before they become cancer.
A (FOBT) faecal occult blood test, looks for blood in the stool, a common potential indicator of pre-colorectal cancer, should be performed annually on predisposed individuals. It is also recommended to perform a colonoscopy, which involves inserting a scope into the anus to remove polyps that could develop into cancer if left untreated. Other tests are occasionally advised to diagnose colorectal cancer( including CT virtual colonoscopy).
Myth 4: The presence of colon polyps means cancer.
Fact: Well, colon polyps have the potential to transform into cancers, and hence, be removed through proper methods. However, not all polyps are cancerous. In 10 and 20 years, the likelihood of polyps turning into cancer varies from 8% to 24%. Approximately 80% of all colon polyps are adenomas and adenomatous polyps are the precursor of 75% of colorectal malignancies. However, only roughly 5% of adenomas are cancerous.
Myth 5: This is fatal
Fact: Yes! Colorectal cancer can be fatal if diagnosed at an advanced stage. It is, therefore, considered the third leading cause of death due to cancer. Data says 65% of colorectal cancer patients were alive up to 5 years after the diagnosis of advanced stage.
Hence, the crux is that recognising symptoms early and this can be lifesaving.
Common symptoms may include: changes in bowel habits (alternating diarrhoea/ constipation), blood in the stool, persistent abdominal discomfort, or unexplained weight loss. If you find any of these symptoms immediately consult a specialist.
