Can prostate cancer be both focal and diffuse?

In prostate cancer, distribution of disease can vary. The gland is often multifocal, meaning multiple tumor foci can be present, and there can also be diffuse involvement where cancer cells spread more broadly throughout the tissue. Because of this, a patient can have a dominant focal lesion alongside areas of diffuse or widespread cancer infiltration. That makes the answer yes—the cancer can be both focal and diffuse. In imaging terms, you might see a discrete suspicious nodule (focal) within a background that shows heterogeneous or more diffuse changes from cancer spread. The options implying it can only be one pattern are too restrictive, since real-world cases frequently combine both focal and diffuse aspects.
