Colorectal Cancer

Colorectal cancer — also referred to as colon cancer — is cancer that develops in the large intestine (colon) or the rectum. It occurs when abnormal cells in the colon develop and grow out of control.

Colorectal cancer risk factors

Colorectal cancer typically affects older adults, especially men older than 50. It can develop in men and women at any age.

Other risk factors can increase the likelihood of developing it, including:

  • Being African American
  • Having a history of smoking or tobacco use
  • Having a family history of colorectal cancer
  • Having an inflammatory bowel disease, such as ulcerative colitis or Crohn’s disease
  • Having a diet that is high in fat and low in fiber 
  • Experiencing a change in bowel movements, blood in your stool or abdominal pain

While these factors can increase your risk for colorectal cancer, the disease can still affect people who have none of them.

Signs and symptoms of colorectal cancer

Symptoms of colorectal cancer can include:
  • A change in bowel habits that lasts for more than a few days, such as diarrhea, constipation or a feeling that your bowel is not empty after a bowel movement
  • Bright red or very dark blood in your stool
  • Constant fatigue
  • Stools that are thinner than usual
  • Stools that look slimy or have mucus on them
  • Ongoing gas pains, bloating, fullness or cramps
  • Unexplained weight loss
  • Vomiting

Generally, any change in your regular bowel habits should be discussed with your doctor.

Early detection is the best prevention

The No.1 way to help prevent colorectal cancer is through receiving regular screening exams, such as a colonoscopy.It’s recommended that regular screenings begin around age 50, or earlier depending on risk factors. Speak with your doctor to find out if it’s time to have a colonoscopy.

Members of the Caregiving Cycle: The Family Caregivers

Acting as a caregiver for a family member can be a rewarding experience, allowing you to spend time and care for someone you love. Caregiving covers a range of situations from those who just need a little extra help caring for themselves to those who are undergoing things such as surgery recovery, cancer treatment and terminal illness. No matter what your role is, one important factor that is often overlooked is who takes care of the caregiver.
