Overview
Colon Cancer
Colon cancer is a malignant growth that develops in the lining of the colon, part of the large intestine. It often begins as a polyp or other abnormal growth that can gradually develop into cancer over time. Early colon cancer may cause few or no noticeable symptoms. Possible symptoms include changes in bowel habits, blood in the stool, abdominal discomfort, unexplained weight loss, weakness, or anemia caused by chronic blood loss. Screening can identify some precancerous polyps and cancers before symptoms appear, while diagnosis and staging help determine the appropriate treatment approach.
Polycythemia Vera
Polycythemia vera is a chronic blood disorder in which the bone marrow produces too many red blood cells. The increased number of blood cells can make the blood thicker and increase the risk of blood clots. Some people also have increased white blood cells or platelets. Symptoms may include headache, dizziness, itching after a warm bath, fatigue, or a feeling of fullness in the abdomen.

Colon Cancer
Colon cancer may be detected through screening tests such as stool-based testing or colonoscopy, depending on age, risk, and applicable screening recommendations. When cancer is suspected, colonoscopy allows direct examination of the colon and removal or biopsy of abnormal tissue. A biopsy is used to establish the diagnosis of cancer. Additional imaging and laboratory evaluation may be performed to determine the stage of disease and whether it has spread to lymph nodes or other organs.
Polycythemia Vera
Diagnosis involves a complete blood count showing an increased red blood cell level and may also show increased white blood cells or platelets. Healthcare professionals may measure erythropoietin levels and test blood cells for JAK2 mutations. Additional evaluation may include examination of the bone marrow and assessment for other causes of an elevated red blood cell count. The diagnosis is based on laboratory findings together with the clinical and medical history.
Prevention
Colon Cancer
The risk of colon cancer may be reduced through recommended colorectal cancer screening, avoiding tobacco, limiting excessive alcohol use, maintaining a healthy body weight, staying physically active, and following a balanced dietary pattern. Screening is particularly important because precancerous polyps can sometimes be detected and removed before they become cancer. People with a family history, inherited cancer syndrome, inflammatory bowel disease, or other increased-risk conditions may require a different screening approach based on medical advice.
Polycythemia Vera
There is no established way to prevent polycythemia vera because it usually results from acquired genetic changes that cannot be predicted or avoided. Early evaluation of persistent abnormal blood counts can help identify the disorder and reduce complications. People with the condition should follow medical treatment and recommendations aimed at reducing blood clot risk, avoid tobacco exposure, and seek urgent care for symptoms that may indicate a serious clotting complication.
Risk Factors
Colon Cancer
Risk factors for colon cancer include increasing age, a personal or family history of colorectal cancer or certain polyps, inherited cancer syndromes, inflammatory bowel disease, smoking, heavy alcohol use, physical inactivity, and certain dietary patterns. Excess body weight and metabolic health factors may also be associated with increased risk. Risk is influenced by multiple factors, and colon cancer can occur in people who do not have an obvious risk factor.
Polycythemia Vera
The risk of polycythemia vera increases with age and is uncommon in children and young adults. It occurs somewhat more often in men than women. Having certain blood disorders or related genetic changes may be associated with increased risk. Unlike secondary polycythemia, lifestyle factors such as smoking or living at high altitude are not the direct cause of polycythemia vera, although they can increase red blood cell counts for other reasons.
