Create a 3D illustration of a transparent human torso, prominently displaying the lungs. The lungs should be depicted in a semi-transparent style, with a small amorphous red toxic mass inside one lung to symbolize lung cancer. This mass should have a yellow outline, making it stand out and appear menacing against the lung tissue. Ensure that the background is simple and unobtrusive to highlight the lungs and the amorphous representation of cancer. The overall image should convey a powerful message about lung health and the dangers of cancer.
