What Are the Signs of Skin Cancer? The Short Answer

Skin cancer typically appears as a new growth, a sore that won’t heal, or a change in an existing mole. The earliest signs vary by type. Basal cell carcinoma often looks like a pearly or waxy bump. Squamous cell carcinoma may present as a firm red nodule or a flat sore with a scaly crust. Melanoma — the most dangerous form — usually shows up as an asymmetrical mole with irregular borders, uneven color, a diameter larger than 6 millimeters, or any mole that evolves over time.

That’s the textbook version. The reality is messier. Some melanomas are colorless. Some basal cell carcinomas look like ordinary eczema. And skin cancer in people with darker skin tones often appears in less sun-exposed areas — palms, soles, under nails — which means it gets missed more frequently. So the signs matter, but so does context: your skin type, your sun exposure history, and whether a lesion is changing.

Who Should Get Checked — and Who Can Wait

A dermatologist’s time is best spent on lesions that show specific warning features. You should prioritize a skin check if you fall into any of these categories:

• You have a personal or family history of melanoma or atypical moles
• You’ve had blistering sunburns, especially in childhood
• You have more than 50 moles, or several that look unusual
• You’ve used tanning beds — even once, risk rises measurably
• You have fair skin, light eyes, or red or blonde hair
• You take immunosuppressive medication
• You notice any lesion that itches, bleeds, crusts, or fails to heal within three weeks

Who can reasonably wait? A stable, symmetric mole you’ve had for years with no changes. A freckle that looks like every other freckle. But “waiting” only works if you actually monitor. Take photos monthly. Compare them. Set a calendar reminder. If you can’t commit to that, get a baseline exam.

What you should not do is self-diagnose based on internet images. A 2021 study in the Journal of the American Academy of Dermatology found that even primary care physicians misclassify skin lesions up to 40% of the time without dermoscopy. If something concerns you, see a specialist.

Diagnostic Options, Compared

Before discussing treatment, you need a diagnosis. Here’s how the main pathways compare — in any country, including China.

For most patients, the right path is dermoscopy first, then biopsy if anything looks suspicious. AI tools are improving fast, but they don’t replace a pathologist reading tissue. If you’re traveling to China for evaluation, a dermatologist at a top hospital can typically perform dermoscopy and biopsy in a single visit.

What Are Early Signs of Melanoma? The ABCDE Rule, Updated

You’ve probably seen the ABCDE mnemonic — Asymmetry, Border irregularity, Color variation, Diameter over 6mm, Evolution. It’s useful but incomplete. Dermatologists now also look for the “ugly duckling” sign: a mole that simply looks different from every other mole on your body, even if it doesn’t meet ABCDE criteria.

And there’s the EFG rule for nodular melanoma — the most aggressive subtype. EFG stands for Elevated, Firm, Growing. Nodular melanoma often lacks the classic color variation. It presents as a raised, uniform bump that grows over weeks or months. It accounts for roughly 15% of melanomas but a disproportionate share of melanoma deaths because it’s caught later.

So the question “what are early signs of melanoma” has two answers. The classic answer: a changing, irregular mole. The overlooked answer: any new raised bump that grows quickly. Both deserve a dermatologist’s eyes.

If you’re considering evaluation in China, several dermatology departments in Beijing and Shanghai use dermoscopy and reflectance confocal microscopy — a non-invasive imaging technique that can reduce unnecessary biopsies. For patients wondering “is skin cancer treatment in China advanced,” the short answer is yes at top-tier centers. Major hospitals in Shanghai and Beijing perform sentinel lymph node biopsy for melanoma, Mohs micrographic surgery for certain basal and squamous cell carcinomas, and offer targeted therapy and immunotherapy for advanced disease.

Skin Cancer Treatment Cost China: What to Expect

Now to the question many international patients ask: what does skin cancer treatment cost China actually look like? Prices vary significantly by hospital tier, city, and case complexity. Here’s a realistic range based on published hospital price lists and patient-reported data from 2023–2025.

Melanoma surgery price Shanghai typically lands in the $1,500–4,000 range for a wide local excision at a top public hospital’s international department. Add sentinel node biopsy and the total climbs. The private international hospitals — United Family, Jiahui, Parkway — charge more but offer English-speaking staff and direct insurance billing.

What’s not included in these figures: pre-operative imaging, pathology fees (often billed separately), hospital stay if needed, and post-operative medications. Always request an itemized quote before committing. And remember — any remote consultation fee you pay through a coordination service can be credited toward on-the-ground care if you proceed within 90 days.

For context on hospital quality, the top-ranked hospitals in China include dermatology departments with substantial melanoma case volumes. The best dermatology hospital Beijing skin cancer patients often consider is Peking Union Medical College Hospital, which consistently ranks among China’s top dermatology programs. In Shanghai, Fudan University’s Huashan Hospital is another strong choice.

Practical Considerations: Records, Visas, and Follow-Up

If you’re planning to book skin cancer screening China, there are logistics worth sorting before you fly.

Medical records. Bring any prior pathology reports, photographs of the lesion over time, and a list of medications. If you’ve had a biopsy done at home, bring the slides if possible. Chinese pathologists will often want to review the original tissue, not just the written report.

Visa. Medical treatment in China falls under the S2 visa category for short stays, with S1 for stays exceeding 180 days. You’ll need an invitation letter or supporting documents from the hospital. Family members accompanying you apply for S2 as well. Processing times vary by consulate, so start at least 4–6 weeks before your intended travel date.

Payment. Public hospitals in China generally require prepayment for services. International departments may accept foreign credit cards; standard outpatient departments often do not. Private international hospitals frequently handle direct insurance billing. If you’re using insurance, confirm coverage for out-of-network international care before you book anything.

Language. Top public hospitals have international departments with English-speaking coordinators. But outside those departments, English is rare. A bilingual medical companion — typically from $300 per day — handles registration, queueing, payment, and translation. You can manage without one, but expect friction.

Follow-up after returning home. Skin cancer follow-up is long-term. Melanoma patients need skin checks every 3–6 months for the first two years, then annually. Before you leave China, ask your surgeon for a written follow-up protocol and digital copies of all pathology and imaging. Your home dermatologist will need them.
