Colon cancer develops in the large intestine. Family history can affect a person’s risk, and colonoscopy screening helps identify polyps or other abnormalities. Because cancer is able to develop without early symptoms, screening and individual risk factors can guide discussions with a colorectal specialist. Here is more information about the role of family history in colon cancer risk:
Understanding Family History’s Influence
Family history is one factor associated with colon cancer risk. Cancer often begins with polyps, and some polyps can develop into cancer over time. Because family history affects individual risk, doctors help review relatives’ histories of colon cancer or polyps during an evaluation. This information may also influence discussions about colonoscopy screening and other diagnostic evaluations.
Recognizing Inherited Risk Factors
Inherited genetic conditions are able to affect cancer risk. Lynch syndrome and familial adenomatous polyposis are hereditary conditions, and both are associated with an increased risk of colorectal cancer. When family history suggests an inherited condition, genetic testing may provide additional information about individual risk.
Genetic counseling can accompany testing for hereditary cancer syndromes. A genetic counselor reviews family history and discusses testing, while results will sometimes influence recommendations for future screening. Because inherited risk varies between individuals, patients are able to discuss appropriate screening plans with their healthcare provider.
Spotting Early Warning Signs
Cancer may not cause symptoms during its early stages. Symptoms are able to develop as the condition progresses, and several may also occur with other digestive conditions. When symptoms appear, they may include:
- Bowel changes
- Narrow stools
- Rectal bleeding
- Abdominal pain
- Abdominal bloating
- Nausea
- Persistent fatigue
These symptoms do not always indicate cancer. A colorectal specialist helps to evaluate persistent symptoms, and diagnostic testing may provide more information about their possible cause. Because blood in the stool or lasting bowel changes warrant evaluation, patients should discuss these symptoms with their healthcare provider.
Pursuing Screening and Testing
Colonoscopy is used to screen for cancer. The procedure allows a specialist to examine the colon, and polyps are able to be removed during the examination when found. Because family history are able to affect cancer risk, screening recommendations can vary according to individual medical circumstances.
Abnormal tissue may require additional evaluation. A biopsy can collect tissue for laboratory examination, while imaging tests are able to provide further information after a cancer diagnosis. When cancer is identified, these findings help determine its extent and guide discussions about available treatment options.
Treating Colon Cancer Effectively
Surgery is a common treatment for cancer. A colorectal surgeon is able to remove the affected section of the colon, and the remaining sections can then be reconnected. Depending on the cancer’s stage and individual findings, treatment may also include chemotherapy or radiation therapy. A colorectal specialist is able to explain the treatment plan and discuss follow-up care after surgery.
Schedule Your Colon Screening
Family history can provide information about colon cancer risk. A colorectal specialist is able to review personal and family medical history, and this information may influence screening recommendations. Because cancer may develop without early symptoms, screening discussions do not need to depend on noticeable changes. Schedule a colon cancer screening consultation today to discuss your family history and appropriate screening options.
