Skin tumor
Skin Tumor
A Skin Tumor (pronunciation: /skɪn ˈtjuːmər/) is a growth or lesion that appears on the skin. It can be either benign (non-cancerous) or malignant (cancerous).
Etymology
The term "tumor" originates from the Latin word 'tumere' which means 'to swell'. The term "skin" is derived from the Old Norse 'skinn', meaning 'animal hide'.
Types of Skin Tumors
There are several types of skin tumors, including:
- Basal cell carcinoma: This is the most common type of skin cancer. It often appears as a slightly transparent bump on the skin, though it can also take other forms.
- Squamous cell carcinoma: This type of skin cancer often appears as a firm, red nodule or a flat lesion with a scaly, crusted surface.
- Melanoma: This is the most serious type of skin cancer. It can develop anywhere on your body, in otherwise normal skin or in an existing mole that becomes cancerous.
- Dermatofibroma: This is a common benign skin tumor that appears as a firm bump under the skin, often with a bluish color.
Symptoms
Symptoms of skin tumors can vary greatly depending on the type of tumor and its location. Common symptoms can include a new growth or sore that doesn't heal, a change in the size or color of a mole, or a rough, scaly patch on your skin.
Causes
Skin tumors are caused by mutations in the DNA of skin cells. These mutations cause the cells to grow out of control and form a mass of cancer cells. Skin tumors can begin in any type of skin cell, but most form in skin cells that are in the outer layer of the skin (epidermis).
Treatment
Treatment for skin tumors depends on the type, size, location, and stage of the tumor, as well as the patient's overall health. Options may include surgery, radiation therapy, chemotherapy, or a combination of these treatments.
