Like a cavity, a melanoma may grow for years before producing any significant symptoms.

What is the life expectancy of someone with skin cancer?

Life expectancy for cancers is often expressed as a 5-year survival rate (the percent of patients who will be alive 5 years after diagnosis). The overall average 5-year survival rate for all patients with melanoma is 92%. This means 92 of every 100 people diagnosed with melanoma will be alive in 5 years.

What is worse squamous or basal?

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.
