What causes a mole to become cancerous?

Hello,

Welcome to icliniq.com.

Thank you for your query.

I understand your concern. The condition appears to be seborrheic keratosis. It appears due to multiple reasons, including genetic susceptibility, where it runs in the family and may be transmitted genetically, due to excess sun exposure, as part of normal skin aging. They are harmless and do not usually require any treatment unless they present symptoms, including itching, change in size, pain, irritation, redness, and color. They may present as a single or multiple raised or macular lesions on the skin and may appear anywhere on the body, including limbs, chest, back, and even scalp and private areas. They appear as macules or waxy light brown to dark to black colored skin lesions and may also vary in size.

I suggest you to follow a few instructions mentioned below.

1. The presence of symptoms may require having them examined by a dermatologist to rule out other causes. They may be usually examined by dermoscopy, wherein the lesions are examined under oil to check for changes in color, vascularisation, ulcers, etc.
2. A biopsy may also be advised in some situations wherein a sample of the lesion may be examined via punch biopsy or shave biopsy to check for cell histology under a microscope to rule out any severe condition.
3. The lesions may also be removed by cryotherapy, lasers, radiofrequency cauterization techniques, excision, or shave biopsy.
4. Avoid sun exposure as much as possible. Make sure to use sunscreens and physical protection like goggles, caps, and clothes to lessen exposure and reduce skin exposure to direct UV radiation.
5. Make sure to keep your skin moisturized daily.

I hope this has helped you. Thank you.
