Calluses are thick, hardened areas of skin that form as a result of pressure or friction. While calluses are generally considered a common, harmless foot condition, a recent study suggests that they could be linked to cancer.

What the study found

The study found that people with calluses on their feet had a significantly higher risk of developing cancer than those without calluses.

Specifically, the researchers observed that the risk of developing a malignant tumor in the foot was nearly three times higher in people with calluses on their feet.

It’s not yet clear why calluses might be linked to cancer, but the researchers have suggested several possible explanations, including:.

The thickened skin of calluses could provide a hospitable environment for cancer cells to grow and proliferate.
The pressure or friction that causes calluses could damage cells and increase the likelihood of mutations that lead to cancer.
People with calluses on their feet may be more likely to develop skin cancer due to increased exposure to sunlight.

What you can do to reduce your risk

If you have calluses on your feet, there are several steps you can take to reduce your risk of developing cancer:.

Wear proper footwear that fits well and provides adequate support.
Avoid wearing high heels or other shoes that don’t fit properly or put unnecessary pressure on your feet.
Moisturize your feet regularly to prevent dry, cracked skin.
Examine your feet regularly for any signs of unusual growths or discoloration.
Use sunscreen on your feet if you’re going to be exposed to sunlight for an extended period of time.

When to see a doctor

If you notice any unusual growths or changes in your feet, it’s important to see a doctor promptly. Your doctor can help determine whether the changes are benign or could be a sign of cancer.

In general, it’s always better to err on the side of caution and seek medical attention if you have any concerns about your foot health.

The bottom line

While calluses are generally considered a common, harmless foot condition, they may be linked to cancer.

If you have calluses on your feet, it’s important to be vigilant about your foot health and take steps to reduce your risk of developing cancer. Following proper foot care practices, wearing good-fitting shoes, and examining your feet regularly can all help protect your feet and reduce your risk.
