Colorectal cancer: prevention through screening

In the medical field, the term “screening”, which is translated in Spanish as “screening”, is the process that looks for a disease in a certain group of people, in order to make a diagnosis or rule out.

For some diseases we can use more than one screening test and its use depends on several factors, such as age, the relative risk of suffering from the disease and the cost that the test may have.

In the current case, we will describe the tests that can be done to screen patients for colorectal cancer.

Cancer is a disease that causes abnormal cell growth in some part of the body.

Colorectal cancer

Colorectal cancer is the second leading cause of cancer death after lung cancer in the United States of America, as reported by the Centers for Disease Control and Prevention (CDC).

Colorectal cancer is caused by the abnormal growth of cells that are located in the large intestine, colon or rectum.


Treatment for colorectal cancer has improved over the years. The use of laparoscopic resection, radiotherapy, and neoadjuvant or palliative chemotherapy are just a few examples of techniques currently used for disease management.

However, these techniques have not had a great long-term impact on patients.

According to trends, in the year 2030 the different types of cancer will increase as a cause of death for patients.

Therefore, to solve the problem – which we are likely to face – we must develop interventions that can improve the quality of life and the years of survival of patients with colorectal cancer.

Risk factor’s

Colorectal cancer has different risk factors: age is the main one and it is more common in men.

If you have a family member who suffered from this disease, you can have up to twice the risk of suffering from it and there are some genetic conditions that increase the risk of developing it.

However, most of them occur “sporadically”. For this and other characteristics of this neoplasm, it is necessary to promote colorectal cancer screening.

When to get screened for colorectal cancer

The recommendation you make US Preventive Services Task Force is to perform screening in patients older than 50 years and up to 75. The American Cancer Society recommends colorectal cancer screening tests from age 45.

The use of different screening methods, such as colonoscopy or fecal occult blood, depends on the individual patient. A series of preventive measures are recommended, including screening. Consult with your doctor if you have questions.
