What’s worse basal cell or squamous?
Though not as common as basal cell (about one million new cases a year), squamous cell is more serious because it is likely to spread (metastasize). Treated early, the cure rate is over 90%, but metastases occur in 1%–5% of cases. After it has metastasized, it’s very difficult to treat.
What type of skin cancer is characterized by light or pearly nodules?

Can you have melanoma for years and not know?
How long can you have melanoma and not know it? It depends on the type of melanoma. For example, nodular melanoma grows rapidly over a matter of weeks, while a radial melanoma can slowly spread over the span of a decade. Like a cavity, a melanoma may grow for years before producing any significant symptoms.
Can you live a long life with melanoma?
almost all people (almost 100%) will survive their melanoma for 1 year or more after they are diagnosed. around 90 out of every 100 people (around 90%) will survive their melanoma for 5 years or more after diagnosis.
What happens if basal cell goes untreated?
This type of skin cancer needs to be treated and has a high cure rate. If left untreated, basal cell carcinomas can become quite large, cause disfigurement, and in rare cases, spread to other parts of the body and cause death. Your skin covers your body and protects it from the environment.

Where does skin cancer spread to first?
Normally, the first place a melanoma tumor metastasizes to is the lymph nodes, by literally draining melanoma cells into the lymphatic fluid, which carries the melanoma cells through the lymphatic channels to the nearest lymph node basin.
