Is That Mole on Your Inner Thigh Normal? When to Seek Melanoma Screening - Oncology

Melanoma


I just saw a news article online about a woman with melanoma in the perineal area, and it reminded me that I have a black raised spot on the inner thigh, right in the crease between my thigh and private area, which has been there for several years.
Is this normal, or should I get it checked out?

There has been no change for many years, so it should just be a common mole.
Subsequent monitoring can be done to check for the following abnormalities: whether there is any elevation in the center, whether the edges have enlarged or become irregular...
If there are no changes, it is advisable to simply observe.

When it comes to moles or skin lesions, particularly in sensitive areas like the inner thigh or genital region, it's essential to be vigilant about any changes in their appearance. The mole you described, which has been present for several years and resembles a typical mole, may be benign, but there are specific characteristics that warrant further evaluation.

Moles, or nevi, can be classified into different types, with the compound melanocytic nevus being one of the common benign forms. However, any mole that changes in size, shape, color, or texture, or that becomes symptomatic (itchy, painful, or bleeding) should be examined by a dermatologist. The ABCDE rule is a helpful guideline for assessing moles:
- Asymmetry: If one half of the mole does not match the other half.

- Border: Irregular, scalloped, or poorly defined edges.

- Color: A variety of colors (brown, black, tan, red, white, or blue) within the same mole.

- Diameter: Moles larger than 6mm (about the size of a pencil eraser) should be evaluated.

- Evolving: Any change in size, shape, color, or elevation, or new symptoms such as bleeding, itching, or crusting.

If your mole does not exhibit any of these concerning features and has remained stable over the years, it may be considered normal. However, given the location and your concerns, it is advisable to consult a dermatologist for a professional evaluation. They may perform a dermatoscopic examination, which allows for a more detailed view of the mole, and if necessary, a biopsy to rule out melanoma or other skin cancers.

Melanoma is a serious form of skin cancer that can develop from existing moles or appear as new lesions. Early detection is crucial for successful treatment, so if you have any doubts or concerns about your mole, seeking a screening is a prudent step. Regular skin checks, especially if you have a family history of skin cancer or numerous moles, are recommended.

In summary, while your mole may be benign, it is essential to monitor it for any changes and consult a healthcare professional for peace of mind and to ensure your skin health. Regular screenings and awareness of skin changes can significantly impact early detection and treatment outcomes for skin cancers, including melanoma.
