For many adolescent girls, the first visit to a gynecologist is surrounded by anxiety, embarrassment, and misinformation. Stories shared among peers, exaggerated portrayals online, and a general lack of education about reproductive health often lead young patients to expect invasive exams or uncomfortable procedures. In reality, the first gynecologic visit is rarely about procedures. Instead, it represents one of the earliest opportunities in medicine to build trust, introduce preventive care, …

Hashimoto's disease is the most common cause of hypothyroidism in children and adolescents, yet it remains frequently overlooked, particularly in adolescent girls. Fatigue, mood changes, weight gain, and cognitive slowing are often attributed to mental health conditions or dismissed as…
Hashimoto’s disease is the most common cause of hypothyroidism in children and adolescents, yet it remains frequently overlooked, particularly in adolescent girls. Fatigue, mood changes, weight gain, and cognitive slowing are often attributed to mental health conditions or dismissed as normal features of puberty, delaying diagnosis and treatment. This pattern reflects a broader failure to recognize how autoimmune thyroid disease presents during adolescence, and how gendered assumptions shape clinical interpretation …

When people think about breast cancer, they picture middle-aged or older women. The pink ribbons, awareness campaigns, and even clinical guidelines overwhelmingly focus on adults. What's almost never discussed is that, though rare, breast cancer can occur in teenagers. And…
When people think about breast cancer, they picture middle-aged or older women. The pink ribbons, awareness campaigns, and even clinical guidelines overwhelmingly focus on adults. What’s almost never discussed is that, though rare, breast cancer can occur in teenagers. And when it does, the diagnosis is often delayed, with consequences that change a young life forever.
Breast cancer in adolescents is extremely uncommon, accounting for less than 1 percent …

Teen girls are turning to chatbots, not for homework help, but for the questions they're too afraid to ask anyone else. Not their parents. Not their teachers. Sometimes not even their closest friends. Instead, they whisper their fears into an…
Teen girls are turning to chatbots, not for homework help, but for the questions they’re too afraid to ask anyone else. Not their parents. Not their teachers. Sometimes not even their closest friends. Instead, they whisper their fears into an empty chat box late at night, hoping the words land softly somewhere.

Menstrual health is one of the most neglected aspects of adolescent care—especially for teens living in poverty. For these adolescents, getting a period doesn’t just mean discomfort—it means missing school, hiding pain, and facing daily choices between basic needs and menstrual products.
