Understanding Colon Cancer and its Symptoms

Let’s face it, cancer is frightening. Most people know someone who has or had cancer, and the results are understandably scary. According to the National Cancer Institute, 38.5 percent of Americans will be diagnosed with cancer at some point during their lifetime. However, thanks to advancements in medical technology and screening techniques, our ability to treat and survive cancer is greater than ever!

Colon and rectum cancer is the fourth most common cancer in the United States, accounting for 8 percent of total new cancer cases in America. Thankfully, when detected early, the disease is highly curable.

Demographics

Colorectal cancer is slightly more common in men than in women. Also, those of African descent are more likely than other ethnicities to develop colon and rectal cancer. Most colon and rectal cancer diagnoses are made in people between the ages of 65 and 74.

Symptoms

In the early stages, colon cancer does not have symptoms. As a result, screening is incredibly important, since it is unlikely for patients to notice their growing health risk until a major problem has developed.


When symptoms present themselves, the most common ones are:

Stages

It may be tempting to write the above symptoms off as hemorrhoids. Don’t! Early detection is incredibly important to treat any cancer. The survival rate of colorectal cancer changes dramatically based on the stage of the cancer.

The following numbers are according to the National Cancer Institute’s SEER database.

Treatments

In all but the latest stage, surgery is very effective at treating colorectal cancer. Depending on how much tissue is effected, doctors may need to remove a portion of your colon to ensure all cancerous cells are removed. Once the disease spreads into other organs, surgically removing the tumor(s) from your colon will not cure you. However, in some situations, it can offer relief from some symptoms.

After the cancer has spread into lymph nodes, chemotherapy and radiation therapy is an option in some cases. These treatments may not cure a patient after the cancer has moved into organs, but can lessen symptoms and prolong a patient’s lifespan.

Screening

Colon cancer is deadly in far fewer cases today than it was in the past, due to advancements in technology and improvements in screening methods. The American Cancer Society, US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology jointly agreed that screening for colorectal cancer and adenomatous polyps should begin in asymptomatic adults at the age of 50. For those at an average risk of colon cancer, the following procedures are recommended:

Some individuals will need colonoscopies at a younger age and/or with more frequency. If any of the following apply to you, you will most likely need a different schedule than the one listed above:

Updated Screening Guidelines

The US Multi-Society Task Force on Colorectal Cancer updated their guidelines last month. Now, its screening recommendations are divided into three tiers. The tiers are determined by their effectiveness.

These new guidelines suggest that African Americans begin tier 1 at age 45, and patients with a family history of colorectal cancer get colonoscopies starting at age 40. Additionally, it suggests that colonoscopies should be discontinued for patients over 75 with no prior negative screening tests or whose life expectancy is less than 10 years.

The US Preventive Services Task Force (USPSTF) recommends adults ages 76 to 85 should decide with their doctors on an individual basis whether or not to have a colonoscopy.
