How Coffee Lowers Risk of Basal Cell Skin Cancer

When you’re sipping your morning coffee, you’re probably not thinking about skin cancer—but a major scientific study suggests you might want to. The research zeroes in on one of the most common yet least aggressive forms of skin cancer, and reveals how your daily cup could play a surprising protective role.

Yes—according to a major prospective study presented at the 10th International Conference on Frontiers in Cancer Prevention Research (sponsored by the American Association for Cancer Research), regularly drinking coffee lowers your risk of developing basal cell carcinoma (BCC), the most frequent type of skin cancer. Specifically, people who drank three or more cups per day saw significant reductions in risk.

What the Study Found on Coffee and Skin Cancer

Researchers investigated links between coffee consumption and three types of skin cancer: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. Their key finding? Coffee drinking specifically reduces the risk of BCC—but not SCC or melanoma.

How Much Coffee Makes a Difference?

The data showed a clear dose-response relationship. Compared to people who drank less than one cup of caffeinated coffee per month:

• Women who drank three or more cups daily had a 20% lower risk of BCC.
• Men who drank three or more cups daily had a 9% lower risk of BCC.

These reductions were observed only with regular, caffeinated coffee. Decaffeinated coffee showed no protective effect against BCC.

Why Caffeine Appears to Protect Against BCC

Lead researcher Dr. Fengju Song, a postdoctoral fellow in dermatology at Harvard Medical School, concluded that “drinking coffee is an important measure to prevent basal cell carcinoma.” The protective effect is believed to come from caffeine—the compound found only in regular coffee, not decaf.

Which Skin Cancers Were Studied?

The study focused on three main types of skin cancer:

• Basal Cell Carcinoma (BCC): The most common form, slow-growing, and rarely fatal.
• Squamous Cell Carcinoma (SCC): More aggressive than BCC but still non-melanoma.
• Melanoma: The most dangerous and deadly form of skin cancer.

Only BCC risk was reduced with increased coffee intake. SCC and melanoma risks remained unchanged regardless of coffee consumption.

Frequently Asked Questions

Does decaf coffee reduce the risk of basal cell carcinoma?

No. The study found that only caffeinated coffee was associated with a reduced risk of BCC. Decaffeinated coffee showed no significant protective effect against basal cell carcinoma.

How many cups of coffee reduce BCC risk?

People who drank three or more cups of caffeinated coffee per day saw risk reductions: 20% lower in women and 9% lower in men. Drinking less than one cup per month showed no such benefit.

Does coffee protect against melanoma or squamous cell carcinoma?

No. This study found that coffee consumption does not reduce the risk of melanoma or squamous cell carcinoma (SCC). The protective effect was specific to basal cell carcinoma (BCC) only.

What causes the protective effect in coffee?

Researchers believe the protection comes from caffeine, which is present in regular coffee but not in decaffeinated versions. No other compounds in coffee were identified as responsible for the BCC risk reduction.

Who was studied in this coffee and skin cancer research?

The study analyzed data from a large population sample examining the relationship between coffee intake and three types of skin cancer. Researchers looked at both men and women with varying levels of coffee consumption over time.
