It is distinct from colon cancer in terms of anatomical location, blood supply, metastatic pattern, and treatment approaches. <a href=\"https:\/\/www.venkateshwarhospitals.com\/oncology\/rectal-cancer.php\">Rectal cancer<\/a> often develops gradually, beginning as small, benign polyps that may become malignant over time.<\/p>\n<p>Recognising the early symptoms of rectal cancer is crucial because early-stage disease can often be treated effectively before it spreads. However, many symptoms overlap with common digestive issues, which can delay diagnosis.<\/p>\n<p>At Venkateshwar Hospitals, patients benefit from advanced diagnostic technologies, <a

It develops when cells in the rectal tissue grow uncontrollably, sometimes beginning as polyps. While often grouped with colon cancer under the term &#8216;<a href=\"https:\/\/www.venkateshwarhospitals.com\/oncology\/colorectal-cancer.php\">colorectal cancer<\/a>,&#8217; rectal cancer is considered a distinct condition due to its unique characteristics.<\/p>\n<p>In most cases, rectal cancer begins as polyps, small growths on the inner wall of the colon or rectum. While many polyps are harmless, certain types, called adenomatous polyps, can turn cancerous if left untreated.<\/p>\n<p>Early detection through screening tests, such as colonoscopy, can identify and remove these polyps before they become malignant. Detecting rectal cancer early often involves a combination of screening and risk assessment, which significantly improves survival and allows for minimally invasive treatments.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Early_Symptoms_of_Rectal_Cancer\"><\/span><b>Early Symptoms of Rectal Cancer<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The early signs of rectal cancer can be subtle and are often mistaken for common digestive issues like haemorrhoids or irritable bowel syndrome (IBS). Persistent or worsening symptoms should not be ignored.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Common_Early_Symptoms\"><\/span><b>Common Early Symptoms<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li><b>Blood in Stool:<\/b> Bright red or dark maroon blood, often mixed with stool.<\/li>\n<li><b>Changes in Bowel Habits:<\/b> Chronic constipation, diarrhoea, or narrow (\u201cpencil-thin\u201d) stools persisting for weeks.<\/li>\n<li><b>Persistent Abdominal or Rectal Pain:<\/b> Pain or discomfort during bowel movements or in the lower abdomen.<\/li>\n<li><b>Unexplained Weight Loss:<\/b> Rapid weight loss without dietary or lifestyle changes.<\/li>\n<li><b>Fatigue and Weakness:<\/b> Often due to blood loss and anaemia.<\/li>\n<li><b>Feeling of Incomplete Bowel Emptying:<\/b> Sensation of still needing to pass stool after a bowel movement.<\/li>\n<\/ul>\n<p><b>Note:<\/b> Rectal bleeding should never be ignored.
