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.
Pheochromocytoma
Pheochromocytoma is a rare tumor that develops from specialized cells of the adrenal glands and can cause excessive release of epinephrine and norepinephrine. These hormones affect heart rate, metabolism and blood pressure. The tumor usually develops in the adrenal gland but can occasionally occur outside it. Episodes may cause severe or recurring headaches, sweating, rapid or pounding heartbeat and high blood pressure. Most pheochromocytomas are not cancerous, although a small number can be malignant.

Diagnosis

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.
Pheochromocytoma
Diagnosis begins with a medical history and physical examination, particularly when episodes of headache, sweating, palpitations or high blood pressure suggest excess catecholamine production. Blood or urine testing can measure catecholamines and related substances such as metanephrines. Imaging studies may then be used to locate the tumor, including CT or MRI of the abdomen and, in selected cases, specialized nuclear imaging such as an MIBG scan. Genetic evaluation may be considered when the history suggests an inherited condition.

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.
Pheochromocytoma
There is no established way to prevent most pheochromocytomas because many develop without a preventable cause. When a hereditary syndrome is present, genetic counseling and appropriate screening of affected families can help identify tumors earlier. Close relatives of people with inherited pheochromocytoma may benefit from evaluation and periodic testing. People who have previously been treated successfully should continue follow-up testing because the tumor can sometimes return.

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.
Pheochromocytoma
Risk factors include having a family history of pheochromocytoma or an inherited syndrome associated with adrenal or endocrine tumors. People with certain hereditary conditions may have a higher likelihood of developing one or more tumors. Pheochromocytoma can occur at any age but is most commonly diagnosed during early to middle adulthood. Close relatives of people with hereditary disease may also need evaluation because some cases are inherited.
