Skin Tags and Growths in the Armpit: What You Need to Know - Dermatology

More Info

---

Skin tags, also known as acrochordons, are benign growths that commonly appear in areas where skin rubs against skin, such as the armpits, neck, and groin. They are typically small, soft, and flesh-colored or slightly darker, and they can vary in size. The presence of a skin tag in your armpit, especially after shaving, is not uncommon. Shaving can irritate the skin and lead to the development of skin tags, particularly if there is frequent friction in that area.

The new red, thin growth you noticed next to the skin tag could be a variety of things. It might be another skin tag, a small blood vessel, or even a form of irritation or inflammation due to friction or shaving. If it is very small and not causing any pain or discomfort, it may not be a cause for concern. However, if it changes in appearance, becomes painful, or starts to bleed, it would be wise to consult a healthcare professional for a proper evaluation.

Regarding your concerns about malignancy, it is important to note that skin tags are generally harmless and do not turn into cancer. However, if you notice any growths that are changing in color, size, or shape, or if they become painful or bleed, these could be signs of a more serious condition, and you should seek medical advice. Malignant growths, such as melanoma or squamous cell carcinoma, often have irregular borders, multiple colors, and may be asymmetrical. If you have any doubts about the nature of your skin growths, a dermatologist can perform a thorough examination and, if necessary, a biopsy to rule out any serious conditions.

In terms of treatment, skin tags can be removed if they are bothersome or for cosmetic reasons. This can be done through various methods, including cryotherapy (freezing), cauterization (burning), or surgical excision. It is generally not recommended to attempt to remove skin tags at home, as this can lead to infection or scarring.

In conclusion, while the skin tag and the new growth you’ve observed are likely benign, it is essential to monitor them for any changes. Maintaining good hygiene and avoiding irritation in the area can help prevent further growths. If you have ongoing concerns or if the growths change, do not hesitate to consult a dermatologist for a professional assessment and guidance. Regular skin checks are also a good practice, especially if you have a history of skin issues or changes.
