72 Year Old Facing Giddiness and Weakness After Prostate Cancer Treatment: Seeking Advice?

I am 81 yrs, suffering from prostate cancer since last 6/7 months. I had earlier multiple health issues like Type 2 Diabetes (2yrs), Alzheimer's, Parkinsons plus, I have also heart issues with two stents inserted in 2014. I follow a very sedate lifestyle with walking for 45-55 mts + physical exercise 30 mts almost each day. I have been able to contain Alzheimer's and Parkinson's to almost 85-90% level and check Diabetes with food habits and walking to almost 70-75% level. . From 212 FPBS t has come down to 111 and PPBS currently is 78. I am focusing on prostate cancer. I wish to give some data for your reference: PSA- Total- from 4.14 it has come down to 1.89 Testosterone- from 585 it has come down to 0.660 reading of 20/05/24 I am strictly following my Urologists instructions so far. I am under his treatment for last 6/7 months. But he advices me to go in for MRI based Radiation therapy at HYD. I am extremely averse to any type of radiation therapy as the cells apparently are in sleeping mode with hormonal therapies but once I go in for radiation even if 85% cells die the balance surviving cells will attack my system vigorously and age will not be able to withstand their attack. Can I continue with hormonal therapies? Your advice please

Doctor I am 61 year male retired and my gall bladder was removed in 2016 and that time i was having slight fatty liver but no pain or discomfort any where other than severe constipation . However , since than I was taking Pan D daily morning . But suddenly 1 and half year back I had severe coughing which continued till last month and local physician prescribed antibiotics and cough syrups and foracourt 200 but coughing did not go . All my chest xray and sputum test came negative . Coughing was more severe when I lie down on bed and was not able to take turn to left side as it was worst coughing that time. i was not able to sleep and severe anxiety , palpitation , dry throat , excessive sweating , all of a sudden feeling cold or hot etc were there . Then I consulted the surgeon who operated the gall bladder he asked for LFT and sonography of upper abdoman . Everything came fine including fasting sugar and HB except SGPT and SGOT levels are high SGPT 200 and SGOT 85 . After this doctor prescribed Veloz IT cap in the morning empty stomach and Obetohep 5mg after lunch both for 2 months and Reflux fort syrup for 7 days along with Anxozap 15mg. Also asked to take no fat meal , fruits , and as I am vegetarian all leafy vegetables , very low sugar and salt . I have followed sincerely and I am walking at least 6000 steps daily. I left smoking for more than 2 months now . I am non alcoholic . Since then situation has improved a bit but not fully . In these conditions it is very difficult to travel to other place as I need to go what should I do will this ever be all right and I can resume my normal food . Please suggest best possible way out .
