Question

skin cancer is the most common cancer in the united states. one in five individuals will be diagnosed with skin cancer by age 70. melanoma is the most serious type of skin cancer and occurs when the cells that give your skin color become cancerous. this type of cancer occurs in ____ tissue, which is part of the ____ organ system. epithelial; integumentary nervous; endocrine connective; digestive muscle; circulatory

Explanation:

• Epithelial tissue: It covers the body's surfaces, including the skin. Melanoma starts in melanocytes (cells in the epithelial - like epidermis layer of the skin that give skin color).
• Integumentary system: Composed of the skin, hair, nails, and associated glands. The skin (where melanoma occurs) is the main organ of this system.
• Nervous tissue is for communication (neurons, glial cells), not related to skin cancer location. The endocrine system is about hormone - secreting glands.
• Connective tissue (e.g., bone, cartilage, blood) is not where skin cancer (from skin - surface related cells) occurs. The digestive system is for food processing.
• Muscle tissue (skeletal, smooth, cardiac) is for movement. The circulatory system is for blood transport.

Answer:

epithelial; integumentary
