Does Picking at Moles Increase Skin Cancer Risk? Expert Insights

Does picking at a mole increase the risk of cancer?

Hello Doctor: I accidentally picked off a mole on my chest, and it came off as a small round black ball.
I would like to ask if this action increases the risk of melanoma in that area? When it grows back, will it definitely be larger than the original? I appreciate your time in answering my questions.
Thank you.

It does not increase the risk of cancer; if you remove it, it may grow back similarly.

More Info

Picking at moles or any skin lesions can indeed raise concerns about skin cancer risk, but the relationship is not as straightforward as one might think. When you pick at a mole, you may cause irritation or trauma to the skin, which can lead to inflammation. However, this does not necessarily mean that it will increase the risk of developing skin cancer, particularly melanoma, which is the most serious type of skin cancer.

The act of picking at a mole does not inherently cause cancer. Skin cancer, including melanoma, is primarily influenced by factors such as genetic predisposition, UV radiation exposure, and the presence of atypical moles or lesions. If a mole is already atypical or has characteristics that suggest it could be precancerous, trauma from picking could potentially exacerbate an underlying issue, but this is not a direct cause-and-effect relationship.

Regarding your specific situation, if you have picked at a mole and it has resulted in a small black ball or scab, it is essential to monitor the area closely. If the mole begins to change in size, shape, color, or if you notice any unusual symptoms such as bleeding, itching, or crusting, it is advisable to seek medical attention. A dermatologist can assess the mole and determine if a biopsy is necessary to rule out any malignancy.

As for the concern about whether the mole will grow back larger, it is possible for a mole to return after being removed or traumatized. However, the size of the regrowth can vary. Some moles may return to their original size, while others may appear larger or change in appearance. This variability can depend on several factors, including the individual’s skin type, the mole's characteristics, and how the skin heals after the trauma.

In summary, while picking at moles does not directly increase the risk of skin cancer, it is crucial to be vigilant about any changes in the mole or surrounding skin. Regular skin checks and awareness of your skin's condition are essential for early detection of potential skin cancers. If you have concerns about a specific mole or skin lesion, it is always best to consult with a healthcare professional who can provide personalized advice and care.
