Skin cancer is often linked to UV exposure, but air pollution can also pose a serious risk. Young adults are especially vulnerable during winter, when the Air Quality Index (AQI) worsens, and pollutants from sources like firecracker smoke fill the air. Exposure to these environmental toxins can increase the chances of developing skin cancer.

Air quality and health

During winter, many urban areas see a rise in particulate matter (PM2.5 and PM10) and harmful gases like nitrogen dioxide and sulfur dioxide. Firecracker smoke adds heavy metals and polycyclic aromatic hydrocarbons (PAHs), which are known carcinogens. When these pollutants are inhaled or settle on the skin, they produce reactive oxygen species (ROS), leading to oxidative stress. This stress damages the DNA in skin cells. Continuous and intense smoke exposure damages the DNA by disrupting cell repair processes and increasing the probability of malignant changes, making these factors environmental cancer triggers.

Mutations of skin cancer

Exposure to ROS and PAHs from pollution can trigger mutations in the skin. These pollutants may damage tumor suppressor genes and oncogenes, causing abnormal cell growth and reducing the natural process of cell death (apoptosis). Long-term oxidative stress can cause non-melanoma skin cancer, but the impact on melanoma needs to be studied. Young adults must be aware of the early warning signs and detection. The signs can be new or changing moles, unhealing sores, or persistent rough patches of skin, especially in areas of frequent pollution exposure. 

Measures to prevent skin cancer risk

Reduce exposure in high-pollution seasons. Reduce outdoor activities on poor AQI days or events generating heavy smoke, like firecracker use. Wear protective clothing and use N95 masks when outdoors to reduce particulate matter inhalation. Add a protective skincare routine, like using antioxidants (vitamin C and E) and broad-spectrum sunscreen daily. Pollution can significantly increase the damaging effects of UV light. Also, young adults should do regular check-ups with a dermatologist, especially those with high historical exposure, to find any suspicious lesions early.

The connection between air pollution and skin cancer is tied to firecracker smoke, and it is worsening winter AQI. This poses a serious public health concern. The environmental impact on skin health and the vulnerability of young adults need awareness and attention. Proactive care on both levels of policy-level pollution control and individual protective measures can help reduce these environmental cancer triggers. With the help of these, we can safeguard the health of future generations.
