Final answer:
Malignant melanoma is a severe type of skin cancer typically treated with surgical removal and immunotherapy, emphasizing the importance of early detection and treatment to prevent metastasis.
Step-by-step explanation:
Malignant melanoma is an aggressive form of skin cancer that starts in the melanocytes, which are cells producing melanin in the epidermis. It is known for its ability to spread quickly to other parts of the body if not treated promptly. Given the seriousness of this condition, the most advised actions are surgical removal and immunotherapy. Surgical removal entails excising the tumor to eliminate the cancer cells, while immunotherapy helps to engage the body's immune system to fight off any remaining cancer cells. Early detection is crucial, hence the use of the ABCDE mnemonic to help diagnose early-stage melanoma which includes checking for Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, and Evolution of moles. Melanoma can be deadly if it metastasizes, highlighting the importance of early detection and treatment.
