Colorectal cancer, also referred to as colon or rectal cancer, affects millions globally, with alarming rates of new cases reported annually. Despite the increasing awareness of the disease, many people remain unsure about its symptoms, making early diagnosis difficult. Recognizing colorectal cancer symptoms and knowing when to seek medical advice can be life-saving, as early-stage detection greatly improves survival rates. Moreover, researchers are also conducting colorectal cancer trials to understand better the genetic factors that influence treatment responses.

What is Colorectal Cancer?

Colorectal cancer starts in the colon or rectum; key parts of the digestive system. The colon extracts water and nutrients from food, while the rectum stores waste before it exits the body. However, colorectal cancer often originates from abnormal growths known as polyps, which can develop into malignant tumors. Therefore, recognizing early symptoms is essential to prevent the disease from advancing.

Key Symptoms to Watch For

Colorectal cancer can present itself in various ways, but some symptoms are common and should never be ignored. It’s important to note that these symptoms do not always indicate cancer, but they require medical attention for further investigation:

  • Changes in Bowel Habits: Sudden or lasting changes like diarrhea, constipation, or narrower stools may indicate a disruption in normal colon function.
  • Blood in Stool: Blood can appear in stool as bright red or darker, tar-like material, having possible bleeding in the digestive tract.
  • Abdominal Pain: Persistent cramps, pain, or bloating can result from tumors obstructing the digestive process.
  • Unexplained Weight Loss: A drop in weight, without any changes in diet or activity levels, may signal digestive issues or an underlying health problem.
  • Fatigue: Persistent tiredness and a lack of energy, especially when combined with other symptoms, can be a sign of colorectal cancer. This may happen due to blood loss, malnutrition, or the body’s efforts to fight cancer.

Who is at Risk?

Colorectal cancer can affect anyone, though some people face higher risks.

  • Age: Those over 50 are more susceptible, though younger adults are being diagnosed more frequently.
  • Family History: A family history of colorectal cancer or polyps increases one’s likelihood of developing the disease.
  • Lifestyle Choices: Smoking, heavy alcohol use, a diet rich in red or processed meats, and lack of physical activity are linked to increased risk.
  • Existing Medical Conditions: Inflammatory bowel diseases like Crohn’s disease or ulcerative colitis also raise the risk of colorectal cancer.

When to Consult a Doctor?

The presence of any of the symptoms mentioned doesn’t necessarily mean you have colorectal cancer. However, it's essential to consult a healthcare professional to rule out any serious conditions. If you experience any of the following, it’s time to seek medical advice:

  • Any appearance of blood in your stool, even if it is occasional.
  • Ongoing abdominal pain or discomfort that lasts beyond a few days.
  • Unexplained weight loss.
  • Changes in bowel habits that persist for more than a few weeks.

Individuals over 50 or those with a family history of colorectal cancer are advised to have regular screenings, such as colonoscopies. Screening can identify polyps or early-stage cancer, even before symptoms arise, increasing the chances of successful treatment.

Current Facts and Advancements

According to the American Cancer Society, colorectal cancer is the third most common cancer diagnosed in both men and women in the United States, with approximately 153,000 new cases reported in 2023. The growing concern of colorectal cancer in younger individuals has prompted revised screening guidelines, now recommending screenings start at age 45.

While traditional treatments like surgery and chemotherapy remain essential components of colorectal cancer care, advancements in targeted therapies and immunotherapies have improved results for many patients. These latest approaches can be effectively combined with traditional methods to create effective care plans that treat cancer comprehensively.

Are You Aware of the Early Signs of Colorectal Cancer?

Colorectal cancer is a serious concern; however, catching it early can lead to better treatment options. By knowing the symptoms and seeking medical help promptly, you can improve your chances for a positive outcome. Moreover, regular screenings and being aware of changes in your body are important steps in managing your health. Therefore, taking these actions helps you stay in control and lower the risks related to colorectal cancer.
