In addition, they lose contact inhibition and can start to grow on top of each other. This can result in formation of a tumor. It is important to make a distinction here: The term “cancer” is used to describe the diseases resulting from loss of cell-cycle regulation and subsequent cell proliferation.

It highlights immediate bodily damage, increased long-term disease risks, particularly cancers and cardiovascular problems, and nicotine's strong addiction potential. Cigarette designs enhance this addiction, making quitting challenging. However, quitting at any age can drastically reduce health risks, though many require several attempts.

Its health benefits were noted in the 1950s, finding a role in preventing diseases related to vitamin E deficiency. Research in the 1980s connected low Se levels to heart disease, underscoring its importance for human health.

Research shows that screening for cervical and colorectal cancers as recommended helps prevent these diseases by finding precancerous lesions so they can be treated before they become cancerous. Screening for cervical, colorectal, and breast cancers also helps find these diseases at an early stage, when treatment works best.

While between 0 and 500 MET minutes per week of vigorousphysical activity, the prevalence of the metabolic syndrome decreased by 37%. To accumulate 500 MET minutes, one would have to engage in about 150 minutes of moderate physical activity and only 75 minutes of vigorous physical activity.
