Wearing sunscreen is a recognized method of cancer prevention, particularly for skin cancers such as melanoma and non-melanoma types. Sunscreen protects the skin from harmful ultraviolet (UV) radiation emitted by the sun and artificial sources like tanning beds. UV radiation can cause DNA damage in skin cells, increasing the risk of cancer. By applying a broad-spectrum sunscreen with an appropriate SPF before sun exposure and reapplying as necessary, individuals greatly reduce their chances of developing skin cancer.

Maintaining a healthy weight is also a critical cancer prevention strategy, as obesity has been linked to several types of cancer. Research indicates that excess body fat can impact hormone levels and lead to chronic inflammation, thereby increasing cancer risk.

Drinking alcohol three times per day would not align with cancer prevention guidelines. While moderate alcohol consumption may have some health benefits, excessive intake is associated with an increased risk of various cancers, including breast and liver cancer.
