melanomas are much more likely than basal cell or squamous cell carcinomas to undergo metastasis. true or false
The correct answer and explanation is:
Correct Answer: True
Melanomas are indeed much more likely than basal cell carcinomas (BCC) or squamous cell carcinomas (SCC) to undergo metastasis. Melanoma originates in melanocytes, the pigment-producing cells found in the basal layer of the epidermis. Though it is less common than BCC or SCC, it is the most dangerous type of skin cancer due to its high potential to spread to other parts of the body.
One of the key features of melanoma is its aggressive nature. Melanoma cells can grow rapidly and invade surrounding tissues. More importantly, they have a strong ability to enter the bloodstream or lymphatic system, allowing them to travel to distant organs such as the lungs, liver, brain, and bones. This process is known as metastasis, and it greatly increases the risk of serious health complications or death.
In contrast, basal cell carcinoma is the most common type of skin cancer, but it grows very slowly and rarely spreads beyond the original tumor site. Squamous cell carcinoma is more likely to spread than BCC, but its metastatic potential is still significantly lower than that of melanoma. Most SCCs remain localized and are treatable when detected early.
Because of melanoma’s high risk of metastasis, early detection and treatment are critical. Warning signs of melanoma include changes in the shape, size, or color of a mole or skin lesion. Health professionals often use the “ABCDE” rule to identify possible melanomas: Asymmetry, Border irregularity, Color variation, Diameter over 6 mm, and Evolution over time.
To conclude, the statement is true. Melanomas are far more likely to undergo metastasis than basal cell or squamous cell carcinomas, which is why they are considered a medical emergency when diagnosed.
