Colorectal cancer (CRC) develops in the colon or rectum, often from non-cancerous polyps that can grow and become malignant. It is among the five most deadly cancers, but it is also one of the most preventable through the early detection and removal of precancerous polyps.
Lifestyle and dietary habits significantly influence the risk of developing colorectal cancer.
Excess weight increases the risk of CRC, especially in men.
Sedentary lifestyles increase the risk due to poorer metabolic health.
Tobacco use contributes to inflammation and DNA damage in the colon.
Diets high in red and processed meats are linked to increased risk.
Excessive alcohol consumption is associated with a higher incidence of CRC.
Symptoms often appear at advanced stages, underlining the importance of regular screening.
Persistent diarrhea or constipation.
Presence of blood in the stool, which may appear bright red or blackish.
Cramps, bloating, or pain

The result of blood loss or the progression of advanced cancer.
Advanced screening methods allow for early detection and prevention.
Benchmark screening tool to identify and remove polyps.Frequency: Every 10 years for individuals at average risk; earlier and more frequently for cases at high risk.
Detect altered blood or DNA in stools
Emerging technology to detect cancer cell DNA in the bloodstream.
Provides a non-invasive visualization of the colon.
Treatment strategies depend on the stage of the cancer and the patient's overall health.
Removal of localized tumors and affected lymph nodes.
Used in advanced or metastatic cases of CRC to slow disease progression.
Often combined with chemotherapy for rectal cancers.
Drugs like bevacizumab target molecular pathways specific to CRC.
Emerging treatments such as checkpoint inhibitors.
