Small Growths on Neck Linked to Diabetes Risk, Doctor Warns

The sudden appearance or enlargement of small skin growths, often referred to as skin tags, on areas like the neck and armpits might signal underlying metabolic abnormalities, according to a dermatologist. While these growths are typically benign, their rapid proliferation could be associated with conditions such as obesity, insulin resistance, and type 2 diabetes.

Skin growths are mostly benign and will not turn into cancer, so there's no need to worry too much.

Dr. Lin Yun-hsuan from Kaohsiung Lin Cheng-hsien Dermatology Clinic explains that these skin tags are common, particularly in individuals over 40, and their numbers tend to increase with age. However, they are not exclusive to older adults and can appear in children as well. Studies suggest a correlation between skin tags in children and higher rates of obesity, type 2 diabetes, high blood pressure, and high cholesterol. In some cases, children with skin tags may also exhibit acanthosis nigricans, a condition causing darkened, thickened skin in folds like the neck and armpits.

If you notice skin growths rapidly increasing in number, or getting larger, it is recommended to also check indicators such as blood sugar and blood lipids.

Recent research further indicates that beyond chronic friction and hormonal changes during pregnancy, skin tags may be closely linked to metabolic health. Dr. Lin advises that if individuals notice a rapid increase in these growths or a significant change in their size, they should consider medical evaluation. This includes checking fasting blood sugar, HbA1c levels, blood lipids, waist circumference, and weight. It is also recommended to rule out endocrine disorders like polycystic ovary syndrome and thyroid issues.

Do not attempt to remove them yourself by tying them with thread or cutting them with nail clippers, as this can cause infection or even delay the diagnosis of the actual lesion.

Dr. Lin strongly cautions against self-removal of skin tags, whether by tying them off with thread or cutting them with nail clippers. Such methods can result in bleeding, infection, and potentially delay the diagnosis of more serious underlying conditions. She emphasizes that if a skin tag rapidly increases in size, appears abnormal, or bleeds repeatedly, immediate medical attention is necessary for professional assessment and appropriate treatment. These growths, therefore, should not be dismissed as purely cosmetic concerns but may serve as a metabolic warning sign from the body.

If skin growths rapidly enlarge, have an abnormal appearance, or bleed repeatedly, seek medical attention promptly for professional evaluation.
