Squamous cell carcinoma (SCC) is a common type of skin cancer that grows from the outer layer of the skin and can invade deeper tissues. It usually appears as a scaly, crusted, or ulcerated spot that slowly enlarges and can destroy nearby skin if not treated in time.
This is general information. With a scan you'll receive a detailed, personalized analysis — including individual risk assessment, progression tracking and recommended actions.
There is no single cause of squamous cell carcinoma, but long‑term UV exposure, radiation, certain chemicals, chronic skin damage, and some rare skin diseases all increase the risk. In some cases, human papillomavirus (HPV) and a weakened immune system also play a role.
SCC can come back after treatment and, in some cases, spread to nearby lymph nodes or distant organs, especially when it is large, deep, or long‑standing. People with one SCC have a higher chance of developing new skin cancers in the future and need regular skin checks.
The main treatment for squamous cell carcinoma is complete surgical removal of the tumor with a margin of healthy skin. Depending on the size, depth, and location, doctors may also use radiotherapy, specialized surgery (like Mohs), or, in advanced cases, systemic treatments such as immunotherapy or chemotherapy.

Lentigo melanoma is a type of melanoma that usually develops on sun‑damaged skin of the face in older adults, often on top of a long‑standing flat brown patch called lentigo maligna (Dubreuilh melanosis). It tends to grow slowly on the surface for years, but once it starts growing deeper it becomes aggressive, can spread to lymph nodes and internal organs, and always needs prompt specialist treatment.
Melanoma is an aggressive skin cancer that develops from pigment-producing cells called melanocytes. It most often appears on the skin but can also occur on the eye, mucous membranes, or under the nails. Early detection and complete surgical removal greatly improve the chances of cure.
You can lower your risk of squamous cell carcinoma by protecting your skin from UV, avoiding tanning beds, preventing chronic skin injuries, and following safety rules when working with skin‑damaging chemicals or radiation. Regular self‑checks, our AI skin analysis, and timely visits to a dermatologist for changing spots are key.
If you notice a persistent scaly patch, a firm pink lump, or a sore that doesn’t heal and bleeds easily, you should see a dermatologist or oncologist as soon as possible. Early diagnosis with a skin exam, dermatoscopy, and biopsy is crucial to confirm or rule out squamous cell carcinoma.
Possible squamous cell carcinoma should be evaluated by a dermatologist or oncologist within days to a few weeks, not months. Go urgently (within days) if the lesion is rapidly growing, deeply ulcerated, very painful, or if nearby lymph nodes feel enlarged or hard.
Bowen disease is an early, non‑invasive form of squamous cell skin cancer where abnormal cells are limited to the top layer of the skin. It shows up as a slowly growing red, scaly patch or plaque that doesn’t heal and can eventually turn into invasive skin cancer if not treated.
