question: 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 bone/hardened 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?
