All uses except for pharmaceutical laboratories in Belgium - Stage IV bladder cancer, tumor invasion, metastases. This medical illustration represents stage IV bladder cancer (primary cancer). The bladder is shown in section in the pelvic cavity to show the extent of tumor invasion. The tumor invaded the entire wall of the bladder and spread inside and beyond outside into the pelvic cavity. The vessels are affected, as well as the lymphatic system. Metastases can then at this stage migrate via the arterial system to other organs. They will then become dormant metastases and may cause secondary cancers. - - Restriction : All uses except for pharmaceutical laboratories in Belgium from 03/28/2022
