What you need to know about colorectal cancer

Colorectal cancer. Those are two words no one wants to hear. According to the American Cancer Society, colorectal cancer is the third most common cancer in the United States with nearly 102,480 new cases of the disease diagnosed in 2013. Fortunately, the death rate from colorectal cancer has been dropping over for more than 20 years due to early screenings and improved treatments.

Undergoing testing to diagnose colorectal cancer may be necessary because of abnormal results from a screening exam or if there are symptoms of the disease, such as a change in bowel habits, abdominal pain, weakness, rectal bleeding or blood in the stool.

Diagnosis may begin with a complete medical history and physical examination. Endoscopic tests to check for colorectal polyps also may be necessary, including a sigmoidoscopy or colonoscopy (procedures used to see inside the colon and rectum), and imaging tests such as a barium enema, double contrast barium enema or virtual colonoscopy. A biopsy is done on any abnormal-looking tissues that are removed during a colonoscopy to confirm the diagnosis of colorectal cancer.

Other imaging tests may be required to determine if a suspicious area is cancerous, learn if the cancer has spread or find out if treatment has been effective. These tests include computed tomography, ultrasound, magnetic resonance imaging, positron emission tomography and angiography.

Once colorectal cancer had been diagnosed, treatment will be determined based on the stage and type of cancer, how far it has spread, overall health, side effects of treatment and long-term prognosis. Surgery usually is recommended for early stage colon cancer. The procedure calls for the removal of part of the colon and nearby lymph nodes. Some stage 0 or early stage 1 tumors can be taken out by removing the base of the polyp or the superficial cancer and a small margin of surrounding tissue.

Colorectal cancer also may be treated with three different types of radiation therapy, which use high-energy rays or particles to destroy cancer cells.

  • External-beam radiation therapy focuses radiation on the cancer from outside the body;
  • Endocavitary radiation therapy delivers radiation through a hand-held device placed into the anus; and
  • Internal radiation therapy (brachytherapy) involves placing small pellets of radioactive material next to or directly into the cancer.

Chemotherapy, which involves administering drugs either into a vein or orally, can be part of a colorectal cancer treatment plan as well. Neoadjuvant chemotherapy may be given along with radiation before surgery to try to shrink some rectal cancers. Adjuvant chemotherapy is given after surgery in case the cancer returns.

It is important to discuss potential side effects of treatment with your doctor. Most side effects should decrease after treatment, but steps can be taken to reduce or relieve them.

Colorectal Cancer Trending Younger

Cancer knows no age. In the past, the average age hit by colorectal cancer ranged from 68-72 years old. However, young-onset colorectal cancer is on the rise, according to the American Cancer Society. The third most common cancer in the United States is colorectal cancer, and it is also the second leading cause of cancer death. Also, cancer knows no gender. It affects men and women across all races and ethnic groups. People of color are more likely to have colorectal cancer at a young age than Whites, but the gap is closing.

Causes of Colorectal Cancer

The cause of the jump in colorectal cancer cases among young adults is still uncertain. However, rising incidence of colorectal cancer by generation suggests that the cause might be environmental rather than biological. Just like with other diseases and conditions, the following may increase a person’s risk for having colorectal cancer:

  1. Obesity
  2. Physical Inactivity
  3. Gut bacteria
  4. History of cancer
  5. Certain genetic conditions

Symptoms of Colorectal Cancer

The common symptoms of colorectal cancer include the following:

  • Diarrhea and/or constipation
  • Change in stool consistency or stools getting narrower
  • Cramps, gas, pain and/or feeling full or bloated
  • Nausea
  • Vomiting
  • Blood in stool
  • Feeling weak or fatigued that may be accompanied with anemia
  • Losing weight for no reason

When Should I See a Doctor?

Please schedule an appointment with a doctor as soon as you experience any of the symptoms above. But it’s good to note that the early signs of cancer often do not include pain. Colorectal cancer may be considered a silent killer because you may not see any symptoms at all. This is also why it’s recommended to make time for regular annual check-ups. Remember: early detection can save lives. Young-onset colorectal cancer is often misdiagnosed, so, if possible, seek a second opinion.

Take Action!

With the rising cases of colorectal cancer in younger individuals, spreading awareness can help decrease mortality rates and increase survival percentages. Some of the ways you can take a step to prevent colon cancer and spread awareness include:

  1. Educating You and Your Family
    Know that colorectal cancer is not an “old man’s disease.” It can affect everyone. Awareness is the first part of taking action. Educate yourself and your family about the symptoms and risks of colorectal cancer by signing up for health-related newsletters and/or reading more about this disease.
  2. Knowing your Risk
    On average, young-onset patients wait for 6.2 months before going to the doctor. If you know you have a family history of colorectal cancer or any similar condition, take the leap and get yourself screened.
  3. Being Your Own Health Advocate
    Be proactive. If you suspect there’s something wrong with your body, please have yourself checked, and get double checked also.

Please take care of yourself and stay aware. We’re here when you need us. As always, your safe care is our #1 priority.
