<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello i m worried about my dad... he went to see the doctor six months ago because of a problem with his Prostate- he s been finding it hard to go to the toilet even though he is desperate. The doc gave him some advice and said that it s normal for a man of his age 55 to have Prostate problems. However, he has also been complaining of a hardened tender lower jaw the area which should consist of tissue- where the bottom of the cranium is located and he explains that it feels like he has a bonehardened lump there. He also has been getting sore throats and feeling like he has lumps in his throat- a little like the feeling of constant Catar build up. Is it possible that this could be cancer of the jaw bone which was brought on by a possible un-diagnosed Prostate cancer?  <response>: Hi. Thanks for your query. Noted your history about your Father. HE has 3 distinct problems1. Related t prostate and the best way to have a proper diagnosis is:- Blood PSA level - Ultrasonography of the whole abdomen and per-rectal sonography of the prostate. - If there is a mass or so, ultrasonography guided biopsy. This will confirm whether there is a benign problem or cancer and to get treated under the guidance of a Urologist for further medical or surgical care as may be needed.2. Feeling of lump in throat-get a clinical evaluation and examination done by an ENT Surgeon to get a proper diagnosis and treatment.3. Hardened tender lower jaw:CT scan will confirm the cause, ENT Surgeon will help further for biopsy, treatment and so on. Hence, all the problems will have proper diagnosis and treatment.
