Cancer screening before 50 years of age? – Harvard Health Center


Bowel cancer (CRC) is the second cause of cancer deaths in the United States. There is a strong evidence that the CRC screening with colonoscopy, other visual examination, or stool tests may reduce CRC death. As a result, many experienced organizations have long been advised by regular CRC research for adults in the United States between the ages of 50 and 75.

In 2018, the Association of Cancer Society (ACS) became the first major advisory committee for the diagnosis of CRC from the age of 45.

Why ACS recommends CRC testing 45?

The symptoms of CRC and mortality decreased in the last decade of adults over 50, which may reflect the effectiveness of the diagnosis. Instead, since the beginning of the 1990s, there was a increase according to CRC cases and deaths of young people under 50.

The greatest risk of anyone under 50 years of age CRC is significantly lower than adults. However, in a natural disorder, young patients are often diagnosed in the next stage, when the disease is more serious than the treatment. It looks like they are experiencing high quality and productive losses due to the death of CRC at the time of death.

ACS advice is based, partly, the predictive system considered as a change of CRC for young people. They were "advised", which ACS suggests "There is clear evidence of the purpose of the investigation but does not make sense of the advantages and disadvantages of the patient and the value of the patient, which may go to & # 39; a variety of investigations. "

Why is the first CRC increase?

The bottom line is that we do not yet know why many people were identified as CRC before age 50. There are a number of critical CRCs, including anthropogenic disease that increases the risk of developing CRC. However, most of the early CRCs happen to people who do not have family history.

Therefore, the latest developments in the start of the CRC are likely to come up with a change in the local environment. Early diagnosis of epidemiologists refers to serious issues such as childhood obesity, eating habits, and early antibiotic use.

The early start of the investigation will reduce the initial CRC?

It is still too early to say. Modeling the model, as one of ACS's considerations, relies on ideas and is limited to non-verbal. For example, the ACS system assumes that the screening will have the same level for those under 50, including 50 to 75. But there is no clinical information to support this. Furthermore, the potential problems of screening for those who are less than 50, as a result of the fraudulent results that may lead to further investigations, is not very detailed.

Other organizations with expertise established in the risk assessment and utilities' CRC survey still have not changed their recommendations. Therefore, at that time, individuals between 45 and 50 should talk to their doctor if they begin 45 or wait until 50.

What else can people do to prevent looga CRC?

In addition to investigations, quitting smoking, high levels of physical activity, obesity and obesity, and the use of alcohol abuse are all known to reduce the risk of CRC. Limiting the use of cooked meat and red meat, especially those prepared for high temperatures (ie mixing and flowing) is also quite reasonable.

Finally, there is strong data supporting the use of aspirin to prevent looga CRC. The US Prevention Services Service recommended you use the continuum of aspirin to prevent CRC. However, the risks associated with aspirin, such as bleeding, anyone thinking of preventing anesthesia should consult with their doctor.
