For the last ten years, oncologists from different parts of the world have been observing a disturbing phenomenon—the diagnosis of cancers which were previously only seen in the elderly is now being made in persons below fifty and often at a later stage. The increase in the number of cases among the young has created a lot of questions, which need urgent answers, about the factors responsible for this change.
Environmental pollution is gradually becoming one of the most worrying and underestimated contributors among the many factors such as diet, lifestyle, and genetics.
Many significant research studies have verified that early-onset cancers are on the rise at a rate that cannot be allocated solely to genetic factors. Enhanced screening has a role in the early detection of certain cases; however, a lot of younger patients do not undergo any routine screening. Therefore, in a lot of situations, the increase in diagnoses reflects an actual rise in the incidence of the disease.
The situation is even more alarming; younger adults frequently have more aggressive tumors of advanced disease presentation partly due to the patients' age and symptoms of being mistaken for other conditions which leads to the delay in the diagnosis.
So, what has changed?
The presence of toxins has gradually become a part of life—it is here to stay—through the very air that all living beings, poison included, inhale, the water we, and even the household items we use, consume, and lastly through food. Scientists are interlinking these toxins with the occurrence of more frequent and vigorous cancerous cells.
Among the pollution-related factors mentioned below, some are already being investigated rigorously:
Researchers suggested those who were born after the 1980s have had a much bigger exposure to the chemicals of industries, plastics, poor air quality, and processed foods during their lifetime compared to the people of previous generations. This means that the environment, which is causing cancer, has changed faster than the human body can adapt.
There are some factors that made that increase vulnerability, including:
Scientists are warning that pollutants are not the only reasons for the occurrence of cancer in young people, but it may represent a significant part of a complex puzzle that includes factors like lifestyle, gut microbiome alterations, genetic predispositions, etc.
Nevertheless, the links between environmental pollutants and cancer risk are so strong that health authorities are demanding the implementation of urgent measures—ranging from cutting down on emissions through regulatory controls over the use of chemicals to personal protective measures.
Everybody has to accept the fact that complete avoidance of environmental exposure is not possible, but nonetheless, these actions can still help in the risk limitation:
The increase in cancer that starts earlier on is a worldwide public health problem that requires immediate and serious attention. Pollution will not be the only cause of this, but growing evidence tends to indicate that it is a more significant factor than earlier presumed. It is likely that dealing with environmental risks—besides early detection and healthier lifestyles—can help turn around these disturbing trends.
Enhanced diagnostics are a factor though; several studies point toward genuine growth in the incidence of cancer among the younger population with the greatest impact on gastrointestinal and hormone-related tumors.
Definitely. A genetic factor is not the only one that comes into play. What is more, environmental factors are justifiably leading to cancer in the absence of family history of the disease through DNA damage, hormone regulation, and immune system alterations.
At least some guidelines are adapting already. For instance, colon cancer screening has now dropped to 45.
Two of the most efficient and handy methods include changing from plastic food containers to glass and using a water filter of very good quality.
