Liver masses or lesions are usually detected on CT scans, and their visibility on these scans depends on the weakening difference between the lesion and the normal liver. [29] They have been shown to inhibit melanoma cell growth,[30][31] increase anti-tumor lymphocytes, and drastically lower tumor mass and disease severity. By bright, I mean brighter then the liver.
