Konstantinidis<\/a>, MD, PhD, FACS, MAMSE, FASMBS, answers questions on this very topical subject, explaining colon cancer and self-tests.<\/p>\n<p>&nbsp;<\/p>\n<h2>What is colon cancer?<\/h2>\n<p>&nbsp;<\/p>\n<p>The <strong>large intestine<\/strong> (colon) plays an important role in our digestive system. It <strong>absorbs<\/strong> water and electrolytes, <strong>contributes<\/strong> to the digestion and absorption of <strong>nutrients<\/strong>, forms and <strong>stores<\/strong> stool, and hosts bacteria that ferment undigested food.<\/p>\n<p><a href=\"https:\/\/kkonstantinidis.com\/en\/karkinos-pacheos-enterou-orthou\/\">Colon cancer<\/a> forms in the wall of the intestine and is characterized by the multiplication of the cells of the intestinal wall. This type of cancer is the <strong>third<\/strong> most common in both men and women, and it is the <strong>fourth<\/strong> leading <strong>cause of cancer death<\/strong> worldwide. More specifically, it affects 1 in 20 people, with 90% of cases occurring in people over the age of 50.<\/p>\n<h2>Colon cancer symptoms<\/h2>\n<p>&nbsp;<\/p>\n<p>Symptoms of colon cancer may include:<\/p>\n<ul>\n<li><strong>Unusual changes in bowel habits<\/strong>: Persistent diarrhea or constipation, or changes in stool consistency.<\/li>\n<li><strong>Rectal bleeding<\/strong>: Blood in the stool or bleeding during a bowel movement.<\/li>\n<li><strong>Abdominal pain<\/strong>: Abdominal pain, cramps or bloating that does not go away.<\/li>\n<li><strong>A feeling of incomplete emptying<\/strong>: The feeling that the bowel does not empty completely after a bowel movement.<\/li>\n<li><strong>Unintentional weight loss<\/strong>: Weight loss for no obvious reason.<\/li>\n<li><strong>Fatigue and weakness<\/strong>: A constant feeling of tiredness or exhaustion.<\/li>\n<li><strong>Unexplained anemia<\/strong>: Anemia caused by blood loss in the intestine, which can lead to fatigue and weakness.<\/li>\n<\/ul>\n<p>It is important to note that the symptoms of colon cancer may be mild or may appear only in more advanced stages of the disease.<\/p>\n<p>&nbsp;<\/p>\n<h2>Causes of colon cancer<\/h2>\n<p>&nbsp;<\/p>\n<p><strong>Colon cancer<\/strong> is one of the most common forms of cancer and can be caused by a combination of genetic, environmental and dietary factors. The main causes and risk factors include:<\/p>\n<ul>\n<li><strong>Genetic factors<\/strong><\/li>\n<li><strong>Diet and lifestyle<\/strong><\/li>\n<li><a href=\"https:\/\/kkonstantinidis.com\/en\/pachysarkia-diavitis-typou-2\/\">Obesity<\/a><strong> and lack of physical activity<\/strong><\/li>\n<li><strong>Inflammatory bowel diseases<\/strong> (<a href=\"https:\/\/kkonstantinidis.com\/en\/elkwdis-kolitida\/\">ulcerative colitis<\/a> and <a href=\"https:\/\/kkonstantinidis.com\/en\/nosos-crohn\/\">Crohn&#8217;s disease<\/a> increase the risk of bowel cancer)<\/li>\n<li><strong>Age<\/strong><\/li>\n<li><strong>Environmental factors (<\/strong>exposure to certain chemicals)<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h2>Colon cancer: diagnosis<\/h2>\n<p>Colon cancer should be diagnosed by a doctor after a clinical examination of the patient. The doctor will guide the patient through every step toward a diagnosis of colon cancer, <strong>avoiding<\/strong> the possibility of a misdiagnosis. Endoscopy, CT, MRI, PET scan, endoscopy of the digestive tract and histological examination (biopsy) are some of the recommended diagnostic tests.<\/p>\n<p>&nbsp;<\/p>\n<h2>Colon cancer and self-tests<\/h2>\n<p>&nbsp;<\/p>\n<p>As part of the prevention and early diagnosis of colon cancer, the Greek government introduced free self-tests for citizens who meet specific criteria. The screening program, aimed at people aged 50-69, seeks to create a comprehensive national prevention plan, so that citizens do not need to visit a doctor first.<\/p>\n<p>However, a positive self-test result does not necessarily mean that cancer is present. Self-tests detect blood in the stool, a possible risk marker for colon cancer, but the <strong>bleeding<\/strong> may also be caused by other conditions of the gastrointestinal tract.<\/p>\n<p>For this reason, it is vital that colon cancer be diagnosed by a <strong>specialized doctor<\/strong>, to ensure a complete and valid screening.<\/p>\n<p>&nbsp;<\/p>\n<h2>Treatment options<\/h2>\n<p>The treatment of colon cancer depends on the stage of the disease, the patient&#8217;s health and other individual factors.<\/p>\n<p>The main treatment methods include:<\/p>\n<p>&nbsp;<\/p>\n<ul>\n<li><strong>Surgical removal of the tumor<\/strong> is the main treatment for colon cancer. The main operations include <a href=\"https:\/\/kkonstantinidis.com\/en\/elkwdis-kolitida\/#kolektomi\">colectomy<\/a> and low anterior resection, depending on the location and extent of the tumor. The most advanced method of surgical tumor removal is <a href=\"https:\/\/kkonstantinidis.com\/en\/robotiki-cheirourgiki\/\">robotic colectomy<\/a>, performed with the da Vinci Xi system. The da Vinci system offers greater precision and better surgical dexterity. It has an infrared camera and Firefly technology, which allow lymph node mapping and assessment of tissue blood supply, making operations safer and more effective.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li><strong>Chemotherapy, immunotherapy and radiation therapy<\/strong>: In some cases, before becoming a candidate for curative surgery, the patient may need chemotherapy or immunotherapy, as well as radiation therapy, from oncologists. In addition, after surgery, the removed tissues\/organs are sent for histopathological examination to determine the stage of the cancer with microscopic precision and to decide on the next steps (chemotherapy, radiation, etc.).<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>Colon cancer<\/strong> is the 4<sup>th<\/sup> deadliest type of cancer, which makes choosing a good surgeon to remove the tumors extremely important. If you have symptoms or have been diagnosed with colon cancer, <a href=\"https:\/\/kkonstantinidis.com\/en\/epikoinwnia\/\">contact<\/a> <a href=\"https:\/\/kkonstantinidis.com\/en\/biografiko\/\">Dr. Konstantinos M. Konstantinidis<\/a> to learn more and get guidance on the surgical procedure.<\/p>\n<h2>Frequently asked questions<\/h2>\n<h3>What are the symptoms of colon cancer?<\/h3>\n<p>They may include unusual changes in bowel habits (persistent diarrhea or constipation, changes in stool consistency), blood in the stool or during a bowel movement, abdominal pain, cramps or bloating that does not go away, a feeling of incomplete emptying, weight loss for no obvious reason, constant fatigue and unexplained anemia. Symptoms may be mild or may appear only in more advanced stages.<\/p>\n<h3>Is the feeling that the bowel does not empty a symptom of cancer?<\/h3>\n<p>A feeling of incomplete emptying, meaning the sensation that the bowel does not empty completely after a bowel movement, is one of the symptoms that colon cancer can cause. The diagnosis must be made by a doctor after a clinical examination.<\/p>\n<h3>What does a positive self-test result mean?<\/h3>\n<p>Self-tests detect blood in the stool, which is a possible risk marker. A positive result does not necessarily mean cancer, because the bleeding may also be caused by other conditions of the gastrointestinal tract. That is why the diagnosis must be made by a specialized doctor.<\/p>\n<h3>Which tests are used for diagnosis?<\/h3>\n<p>The diagnosis is made by a doctor after a clinical examination. The tests used include endoscopy, CT and MRI scans, PET scan and histological examination with a biopsy.<\/p>\n<h3>How is bowel cancer treated?<\/h3>\n<p>Treatment depends on the stage of the disease, the patient&#8217;s health and other individual factors. The main method is surgical removal of the tumor, with a colectomy or low anterior resection depending on the location and extent of the tumor, and the most advanced option is robotic colectomy with the da Vinci Xi system. In some cases, chemotherapy, immunotherapy or radiation therapy is needed before or after surgery.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>&nbsp; Colorectal cancer is one of the most common cancers and one of the leading causes of death.
