[|Human|] my father undergone TURP in 2006 and biopsy report was non malignent.but as psa level was more than 40 the sugeon prescribed cyptamed for 3 months.as psa level lowered to around 12, doctor reexamined the sample but the report was same..The surgeon then prescribed lupride(3.75),one each in next three months.afterwards psa level lowered down below 2.medine was stopped for next 2 years but when psa was again checked the level found to be plus 40.this time lupride(11.25) was adminstered,one each in next three months.medicine was stopped as the psa leve fall below 2.Last months psa test  showed psa level shoot up to 39.My father(90 yrs old) is reluctant to visit a doctor because he is not suffering from urination problem nor he is aware that he was being teated with cancer medicine.Would you kindly suggest what should be the best step forward.
[|AI|]  Hello. The treatment that has received his father is correct. A prostate cancer in a person of 50 years, the treatment is removed the prostate and radiotherapy. The treatment is aggressive, but the benefits outweigh the adverse effects. A prostate cancer in a person of 90 years, must be considered that life expectancy is short and cancer progress slowly. Surgery and radiotherapy cause more adverse effects than benefits and therapy is injected hormonal treatment. If PSA level is now in 39, the injected hormonal treatment would need again. Althought now he don't have pain, the cancer can spread to the bones and cause pain. I wish you good health.(In case the answer would have been useful please indicate this)
