@nooraalhamade, I'm sorry that you do not have trust in the doctors who are treating your father. That must be difficult. I know that you are afraid. You love your father and want the best for him.

However, do not let your fear of chemotherapy stand in your way. Keep asking questions until you are comfortable that the treatment options are the best for your father. It is unclear to me whether the symptoms your father is experiencing are related to metastatic prostate cancer or possibly a new cancer of the bladder. These are questions you can and should ask his care team.

- Is treatment for prostate cancer or bladder cancer?
- Is the malignant tumor in the bladder metastatic prostate cancer or a new cancer?
- What treatment options are available?
- What are the side effects, risks and benefits for each option?
- What other considerations, like my father's health status or preferences, should be considered?

Getting as much knowledge as you can may help reduce your fear. I'm sending you courage.
