Question 52

Long-term sun exposure is the primary factor that causes basal cell carcinoma.

Basal cell carcinoma is primarily caused by long-term exposure to the sun's ultraviolet (UV) radiation, which leads to skin damage and increases the risk of this type of skin cancer.

A) Wounds with open sores

While wounds and open sores can lead to various skin conditions, they are not a primary cause of basal cell carcinoma. This type of skin cancer is more closely associated with UV exposure rather than injury or infection.

B) Exposure to artificial radiation

Although artificial radiation can contribute to skin cancer risk, it is not the primary factor for basal cell carcinoma. Natural sunlight, especially UV rays, plays a far more significant role in the development of this cancer.

C) Long-term sun exposure

This option is correct as long-term sun exposure is the most significant risk factor for basal cell carcinoma. Chronic exposure to UV radiation from the sun leads to mutations in skin cells, which can result in cancer.

D) Arsenic poisoning

Arsenic poisoning has been linked to various health issues, including skin cancers, but it is not the primary factor for basal cell carcinoma. The predominant cause remains related to UV exposure from sunlight.

Conclusion

Long-term sun exposure is definitively the primary cause of basal cell carcinoma, as it leads to cumulative damage in skin cells over time. Other options such as wounds, artificial radiation, and arsenic poisoning do not have the same level of impact on the development of this particular skin cancer. Therefore, understanding the role of UV exposure is crucial for prevention and awareness.
