The scalp is one of the highest-risk locations on the body for skin cancer, yet it is also one of the least examined. Clinicians frequently skip thorough scalp checks, and patients can't easily see what's growing under their hair. That combination of biological aggressiveness and delayed detection is what makes scalp skin cancers stand apart from the same tumors elsewhere on the body.
Despite being a relatively small area, the scalp accounts for a disproportionately high share of squamous cell carcinomas and other keratinocyte cancers. Cutaneous squamous cell carcinoma (cSCC) on the scalp carries local recurrence rates of roughly 6 to 10 percent and lymph node metastasis rates around 7 to 9 percent, numbers that earn it a "high-risk" classification. Basal cell carcinoma (BCC) is still the most common malignant scalp tumor overall, followed by cSCC, with melanomas and rarer tumors also occurring in this location.
Cancer RiskMar 19, 2026
A single high iron or ferritin reading on your blood work is not a cancer diagnosis. But it's not meaningless either. Large cohort studies and meta-analyses link very high serum iron with increased incidence and mortality from several cancers, especially liver and breast. At the same time, other equally large studies find no overall increased cancer risk with higher ferritin, and some even show lower risk or mortality at higher levels. The picture is messy, and the details matter far more than the headline number.
One large health-system study found that people with markedly elevated ferritin had about 1.9 times higher odds of a new cancer diagnosis, with the strongest associations in blood, liver, and lung cancers. That sounds alarming in isolation. But ferritin rises for a long list of reasons that have nothing to do with cancer, and the connection varies dramatically depending on the type of tumor.

Thyroid ultrasound is the first-line imaging test for thyroid problems, and its job extends well beyond spotting lumps. It evaluates cancer risk, characterizes diffuse diseases like Hashimoto's and Graves', guides biopsies, and increasingly uses AI to standardize what doctors see. The reason it holds this central role: it's non-invasive, fast, and highly sensitive for detecting structural abnormalities in both the gland itself and nearby lymph nodes.
What makes modern thyroid ultrasound particularly useful is that it doesn't just flag something as "there." It runs that finding through a structured scoring system to help your doctor decide whether you need a biopsy, treatment, or simply time.
