Why is cancer most common in epithelial tissue?
Since these tissues are often exposed to environmental insults such as chemicals and solar radiation and are often divide rapidly to replace lost cells, many cancers arise in epithelial tissues. cells, those cells that line the surface of our skin and organs.
Which is worse basal cell or melanoma?
While it is less common than basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), melanoma is more dangerous because of its ability to spread to other organs more rapidly if it is not treated at an early stage. Learn more about melanoma types, risk factors, causes, warning signs and treatment.
What is Merkel cell cancer?
Merkel cell carcinoma is a very rare disease in which malignant (cancer) cells form in the skin. Sun exposure and having a weak immune system can affect the risk of Merkel cell carcinoma. Merkel cell carcinoma usually appears as a single painless lump on sun-exposed skin.
