Can using a scented ballpoint pen cause cancer?

Under normal circumstances, long-term use of scented ballpoint pens may pose a cancer risk. The specific analysis is as follows:

Ballpoint pens are typically composed of a plastic tube and a metal casing. The plastic tube may contain toxic components, some of which could be released and cause significant harm to human health. For example, the chemical substances used in manufacturing the plastic tube may have negative effects on the body. Toxic components can easily mix with food or water, thereby adversely affecting human health. Moreover, if a ballpoint pen is designed with added fragrance, it becomes more likely to produce harmful substances, as the fragrances, flavorings, and aromatic agents used in the pen may contain flammable and toxic materials. When the pen is exposed to heat, these toxic substances can easily volatilize. When combined with gases in the air, they may pose potential health risks. More alarmingly, research indicates that certain toxic substances may lead to cancer. For instance, studies have found that aromatic hydrocarbons present in some fragrances and flavorings may cause liver cancer, intestinal cancer, and gallbladder cancer.

In summary, using scented ballpoint pens may expose the body to toxic ingredients over prolonged periods, potentially leading to the development of cancer. Therefore, when using ballpoint pens, one should exercise caution and opt for unscented varieties whenever possible to minimize direct contact with harmful substances.
