In this blog post, we\u2019ll look at those rates, how doctors diagnose colorectal cancer, the important role that early detection has played in these promising trends, and what it all means for you.\u00a0<\/span><\/p>\n<h3>The Numbers Are Encouraging<\/h3>\n<p><span style=\"font-weight: 400;\">Based on data from the <\/span><a href=\"https:\/\/seer.cancer.gov\/statfacts\/html\/colorect.html\"><span style=\"font-weight: 400;\">National Cancer Institute<\/span><\/a><span style=\"font-weight: 400;\">, we can conclude that new colorectal cancer cases and deaths have plummeted over the last few decades. At the same, survival rates have improved.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">From 1976 to 2019, colorectal cancer deaths have gone down from 61.3 per 100,000 people to 12.8.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">New cases peaked in 1985 at 66.6 per 100,000 people.

Better diagnostic tests, regular screening, and early detection are partially responsible for these dramatic improvements.<\/span><\/p>\n<h3>Colorectal Cancer Diagnosis and Staging<\/h3>\n<p><span style=\"font-weight: 400;\">Doctors use a wide range of colorectal cancer diagnostic tools and methods. Some are more invasive than others, but all have a place in the arsenal used to fight the disease.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To determine which diagnostic tool or method to use, doctors consider the following factors:\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The patient\u2019s symptoms\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The type of cancer suspected<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Conclusions drawn from earlier tests<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The patient\u2019s general health and age<\/span><\/li>\n<\/ul>\n<h3>Physical Exam<\/h3>\n<p><a href=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/2.jpeg-6_11zon-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-32499\" title=\"Woman's hand holding a man's hand\" src=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/2.jpeg-6_11zon-1.jpg\" alt=\"Woman's hand holding a man's hand\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/2.jpeg-6_11zon-1.jpg 600w, https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/2.jpeg-6_11zon-1-300x200.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">A physical exam is the first step to establishing if something is wrong with your colon. During your exam, your doctor may insert a lubricated, gloved finger into your rectum to feel around for lumps that shouldn\u2019t be there. Your doctor will also feel your abdomen and may examine your prostate.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Discussing your medical history and family history of colorectal cancer is also essential for establishing your risk profile. During the initial stage of the examination, you can talk to your doctor about any <\/span><a href=\"https:\/\/www.edrugstore.com\/blog\/current-health-news\/colon-cancer-signs-and-symptoms\/\"><span style=\"font-weight: 400;\">symptoms<\/span><\/a><span style=\"font-weight: 400;\"> you may have.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Your doctor <\/span><a href=\"https:\/\/aacrjournals.org\/cebp\/article\/29\/3\/549\/72110\/A-New-Comprehensive-Colorectal-Cancer-Risk\"><span style=\"font-weight: 400;\">may also consider<\/span><\/a><span style=\"font-weight: 400;\"> environmental and lifestyle factors to help determine your risk.\u00a0<\/span><\/p>\n<h3>Colorectal Cancer Screening Tests<\/h3>\n<p><span style=\"font-weight: 400;\">The next step in the diagnostic process is screening. Non-invasive colorectal screening tests look for blood in your stool. Some blood may be visible, but if cancerous lesions cause bleeding deep inside your colon, you won\u2019t be able to see the blood with the naked eye. To detect this internal bleeding, your doctor will recommend stool testing.<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">Fecal Occult Blood Tests (FOBT)<\/span><\/i><span style=\"font-weight: 400;\">\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <\/span><\/h4>\n<p><span style=\"font-weight: 400;\">FOBT tests require a stool specimen you can collect in the privacy of your home. Collect samples from three different bowel movements to cast a wider net for possible problems. FOBT tests use a chemical that changes color when it comes in contact with blood from the stool sample.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">Fecal Immunochemical Tests (FIT)<\/span><\/i><span style=\"font-weight: 400;\">\u00a0<\/span><\/h4>\n<p><span style=\"font-weight: 400;\">FIT also requires stool samples from three bowel movements. Instead of a color-changing chemical agent, FIT-testing uses antibodies linked to hemoglobin to detect blood.\u00a0<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">FOBT vs. FIT<\/span><\/i><i><span style=\"font-weight: 400;\">\u00a0<\/span><\/i><\/h4>\n<p><span style=\"font-weight: 400;\">Of the two screening methods, FIT has <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC4972062\/\"><span style=\"font-weight: 400;\">better detection rates<\/span><\/a><span style=\"font-weight: 400;\"> and is more popular. Many home colorectal cancer tests use the FIT method, as it\u2019s more reliable.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can <\/span><a href=\"https:\/\/www.edrugstore.com\/colorectal-cancer-screening\/\"><span style=\"font-weight: 400;\">order a colorectal screening test kit<\/span><\/a><span style=\"font-weight: 400;\"> online, collect your stool samples, and mail them to a lab. In a few days, you\u2019ll get your results online. If your test is positive, your doctor may recommend further tests to confirm a colorectal cancer diagnosis.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Colorectal screening test kits are non-invasive, easy to use, and usually more affordable than an office visit. <\/span><b>\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<\/b><\/p>\n<h3>Blood Tests<\/h3>\n<p><span style=\"font-weight: 400;\">In addition to stool screening, doctors may order blood tests to help with diagnosis or to monitor the disease. Blood tests alone can\u2019t diagnose colon cancer. In many colon cancer patients, blood work turns out normal. In others, abnormal results appear for other reasons.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Blood work can, however, provide additional information that can help doctors make an accurate diagnosis. Doctors may use blood tests to screen for any of the following:\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Tumor markers. <\/b><span style=\"font-weight: 400;\">Cancer cells create tumor markers that may show up in blood tests.

If colon cancer spreads to the liver, it may disturb these enzymes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Anemia.<\/b><span style=\"font-weight: 400;\"> Anemia, a shortage of red blood cells, can be caused by excessive bleeding. Some colon cancers may cause significant blood loss.\u00a0<\/span><\/li>\n<\/ul>\n<h3>Colonoscopy and Biopsy<\/h3>\n<p><span style=\"font-weight: 400;\">If your doctor suspects cancer after diagnostic testing, they will likely order a colonoscopy and\/or biopsy.\u00a0<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">Colonoscopy<\/span><\/i><\/h4>\n<p><span style=\"font-weight: 400;\">Colonoscopy is one of the most effective colorectal cancer screening methods. It is also doctors\u2019 top choice for colon cancer diagnosis.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">During a colonoscopy, the doctor will insert a thin, flexible tube through your rectum and colon. The colonoscope has a light at the end, a camera, and an opening through which the doctors can use various tools to collect samples and remove polyps.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition to diagnosing colon cancer, doctors might be able to treat early-stage colon cancer through colonoscopy.<\/span><span style=\"font-weight: 400;\">\u00a0<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">Biopsy<\/span><\/i><i><span style=\"font-weight: 400;\"> and <\/span><\/i><i><span style=\"font-weight: 400;\">Biomarker Testing<\/span><\/i><i><span style=\"font-weight: 400;\">\u00a0<\/span><\/i><\/h4>\n<p><span style=\"font-weight: 400;\">The only way to diagnose colorectal cancer beyond doubt is to take a tissue sample and analyze it under a microscope. Doctors can take biopsies during a colonoscopy. In addition to diagnosis, biopsy and colonoscopy can help doctors determine the stage of colon cancer.<\/span><i><span style=\"font-weight: 400;\">\u00a0<\/span><\/i><\/p>\n<p><span style=\"font-weight: 400;\">By analyzing a biopsy at the <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC7432436\/\"><span style=\"font-weight: 400;\">molecular level<\/span><\/a><span style=\"font-weight: 400;\">, doctors can determine the best treatment options for a tumor. They can see, for instance, if <\/span><a href=\"https:\/\/www.edrugstore.com\/blog\/current-health-news\/colorectal-cancer-treatment-immune-checkpoint-therapy\/\"><span style=\"font-weight: 400;\">immunotherapy<\/span><\/a><span style=\"font-weight: 400;\"> is a viable treatment option.

Doctors use a smaller, rigid probe for proctoscopy.\u00a0<\/span><\/p>\n<h3>Imaging<\/h3>\n<p><a href=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/3.jpeg-5_11zon-1.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-32500\" title=\"Woman in a CT scan machine\" src=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/3.jpeg-5_11zon-1.jpg\" alt=\"Woman in a CT scan machine\" width=\"600\" height=\"400\" srcset=\"https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/3.jpeg-5_11zon-1.jpg 600w, https:\/\/www.edrugstore.com\/blog\/wp-content\/uploads\/2022\/04\/3.jpeg-5_11zon-1-300x200.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400;\">Doctors may use imaging to determine how far cancer has spread in the body, how well treatment is working, and whether cancer has returned in a previously treated patient.\u00a0<\/span><\/p>\n<h4><i><span style=\"font-weight: 400;\">Computed Tomography (CT)<\/span><\/i><\/h4>\n<p><span style=\"font-weight: 400;\">A CT scan creates high-resolution images of the patient\u2019s internal organs using X-rays.
