Description of intervention(s) / exposure
Treatment: Drugs - [68Ga]GA-NeoB

Active comparator: Active Intervention - The intervention comprises vegetable burger containing high nitrate vegetables (100g of spinach, \~1000mg/kg FW nitrate) on white bread sandwich, provided at breakfast and lunch.

Experimental: 68Ga Bombesin PET/CT (NeoB) imaging for staging breast cancer - All patients will undergo a single time point imaging at Day 0 with PET CT to be conducted 120 (+/- 30) minutes after intravenous administration with 68Ga NeoB (3.0MBq/kg or up to a maximum of 250 Mbq).


Treatment: Drugs: [68Ga]GA-NeoB
Is a positron emission tomography (PET) imaging agent, intended as a selection tool for \[177Lu\]Lu-NeoB treatment in patients with tumors overexpressing gastrin releasing peptide receptor (GRPR).
