What Is Colorectal Cancer?

Because it is one of the most common cancers worldwide, knowing the signs and risks can help save lives. Early detection often leads to better outcomes. Therefore, learning about colorectal cancer can help you and your loved ones stay healthy.

Common Symptoms of Colorectal Cancer

Colorectal cancer symptoms can be mild at first. However, some signs may appear as the disease grows. Not everyone will have all symptoms. Still, it is important to watch for changes in your body. If you notice any of the following, talk to your doctor:

Blood in your stool or rectal bleeding

Ongoing stomach pain or cramps

Unexplained weight loss

Changes in bowel habits, such as diarrhea or constipation

Feeling tired or weak without a clear reason

Sometimes, these symptoms can be caused by other conditions. Even so, it is best to get checked if you have concerns.

Main Causes and Risk Factors

Colorectal cancer does not have a single cause. Instead, several risk factors can increase your chances. Some you can control, while others you cannot. Knowing these can help you make healthy choices.

Age: Most cases happen in people over 50

Family history: Having close relatives with colorectal cancer raises your risk

Diet: Eating lots of red or processed meat may increase risk

Low physical activity: Not moving enough can be a factor

Obesity: Being overweight is linked to higher risk

Smoking and heavy alcohol use: Both can raise your chances

Certain health conditions: Inflammatory bowel diseases, like Crohn’s or ulcerative colitis, can increase risk

Although you cannot change your age or family history, you can make lifestyle changes to lower your risk.

How Is Colorectal Cancer Diagnosed?

Colorectal cancer diagnosis often starts with a doctor’s visit. If you have symptoms or are at higher risk, your doctor may suggest tests. Early diagnosis can lead to better treatment results. Common diagnostic methods include:

Colonoscopy: A doctor looks inside your colon with a thin, flexible tube

Stool tests: These check for hidden blood or abnormal DNA in your stool

Imaging tests: CT scans or MRIs can help find tumors

Biopsy: A small tissue sample is taken and checked for cancer cells

Screening is key, especially for people over 45 or with a family history. In some areas, local health programs offer free or low-cost screening. Ask your healthcare provider about options in your city or region.

Treatment Options for Colorectal Cancer

Colorectal cancer treatment depends on the stage and location of the cancer. Your doctor will discuss the best plan for you. Common treatments include:

Surgery: Removing the cancerous part of the colon or rectum

Chemotherapy: Using drugs to kill cancer cells

Radiation therapy: Using high-energy rays to destroy cancer

Targeted therapy: Medicines that attack specific cancer cells

Sometimes, doctors use a mix of these treatments. Early-stage cancers may need less treatment, while advanced cases may require more. Your care team will guide you through each step.

Prevention Strategies and Healthy Lifestyle Tips

Although not all cases can be prevented, you can lower your risk with healthy habits. Here are some tips for colorectal cancer prevention:

Eat more fruits, vegetables, and whole grains

Limit red and processed meats

Stay active with regular exercise

Keep a healthy weight

Avoid smoking and limit alcohol

Get regular screening as recommended by your doctor

In addition, talk to your doctor about your personal risk. They can help you make a plan that fits your needs.
