[|AI|]  Hi, Thanks for writing in. Any patient who is recovering from surgery for prostate cancer and is taking treatment will have a lowered immune status. This means that he might get infections and prone to develop cold and nasal Chat Doctor.  These symptoms are related to sinus infection and are not directly from the prostate cancer. The PSA levels will not cause any cold and sinus infection. However, it is important to give him treatment with stronger antibiotics if the ones he is taking do not show response. Extreme temperatures and weather conditions will increase chances of severe infection, and he must keep distance from dust pollution and weather changes. Please do not worry.
