When my mother got surgery for breast cancer, she underwent chemo and radiation. Then begun complaining about very sharp pain in her right side ribs. The surgeon decided to remove the gallbladder. Then the pain got worse, she was sent to psychiatric evaluation, which was clean. The whole thing took a year. Finally, they did a scintigraphy: turns out she had a tumour on her dorsal vertebrae that had collapse and fused 2 vertebrae. She went on to live a couple more years until 2017 when she finally died from a mixture of cachexia and opioid poisoning (low kidney function coupled with a morphine injection at the hospital), cancer already had spread from the breast to the spine, and liver. Before all this, when the cancer was presumably only in the spine, she was offered a experimental treatment with radioactive strontium at the Champalimaud center. Unfortunately, we didn't had enough money at the time. I'm pretty sure things would have been very different now, but I would say to anyone with cancer: get a PET scan if you have strange "psychological" symptoms after having had cancer in the past
