Cancers are the growth of abnormal cells and tissues. No need to tense, no chance

Fissures in the anus and hemorrhoids (piles) are common conditions that affect the anal area. While they can cause discomfort and bleeding, they do not directly lead to colon or rectal cancer. Fissures and hemorrhoids are usually the result of straining during bowel movements, constipation, or other factors that cause pressure on the anal area. Colon and rectal cancer, on the other hand, develop from the growth of abnormal cells in the colon or rectum over a long period of time. The exact causes of colorectal cancer are not fully understood, but they can involve a combination of genetic, environmental, and lifestyle factors. It's important to note that having fissures or hemorrhoids does not increase your risk of developing colorectal cancer. However, it's always a good idea to pay attention to any changes in your bowel habits or symptoms that persist or worsen over time.
