Calluses, also known as corns, are thick patches of skin that form on areas of the body that experience repetitive friction or pressure.

While calluses are typically harmless and can even provide a protective layer for the skin, a new study has found a potential link between calluses on the feet and the development of skin cancer.

The Study

The study, conducted by researchers at the University of Sao Paulo in Brazil, analyzed medical records and tumor samples from 105 patients who had been diagnosed with skin cancer on their feet.

The researchers found that 61% of the patients had calluses on their feet, while only 36% of the control group (patients without skin cancer) had calluses.

The researchers also analyzed the tumor samples to determine if there was a connection between the location of the tumor and the location of the callus. They found that 55% of the tumors were located on or near calluses on the feet.

The Connection

The researchers believe that the connection between calluses and skin cancer on the feet is due to the fact that calluses can hide early signs of skin cancer, such as a mole or a growth.

When a callus forms, it can cover up a small lesion or abnormal growth, making it difficult to detect. Over time, the lesion or growth can turn into a tumor.

In addition, calluses can be caused by repeated exposure to UV radiation from the sun. This exposure can also increase the risk of developing skin cancer.

Prevention and Treatment

While this study sheds light on the potential link between calluses and skin cancer on the feet, it is important to note that calluses themselves do not cause cancer.

However, if you have calluses on your feet, it is important to be vigilant and regularly check for any signs of skin cancer.

Here are some steps you can take to prevent and treat calluses:.

Wear proper footwear

Wearing shoes that fit properly and provide adequate support can help prevent calluses from forming in the first place. Avoid shoes that are too tight or too loose, as they can cause friction on the skin.

Moisturize your feet

Dry skin can contribute to the formation of calluses. Use a moisturizer regularly to keep your feet soft and supple.

Use a pumice stone

If you already have calluses on your feet, gently use a pumice stone to reduce their size and thickness. Be careful not to overdo it, as excessive rubbing can cause the skin to become irritated.

See a doctor

If you notice any unusual growths or changes in the skin on your feet, see a doctor right away. Early detection is key in treating skin cancer.

Conclusion

While this study highlights a potential link between calluses and skin cancer on the feet, it is important to keep in mind that calluses themselves do not cause cancer.

By practicing good foot care and regularly checking for signs of skin cancer, you can help reduce your risk of developing this condition.
