Hi .
You are worried that you are taking lot of medicine for fungal treatment and prostatitis as it seems from your text, that it may cause cancer in future.
Okay. It is good to stay alert but it is not good to worry. U see. Staying alert makes you take action at the right time but worrying can add on more problems.
So, prevention is better than cure. Eat healthy with a lot of antioxidants. Ur medicines can add toxins and free radicals in the body , so need to clear them with good diet and plenty of fluids .
In case of family history of cancer , we follow NCCN guidelines for screening particular carcinomas but if you don't have family history, it is good to modify lifestyle, maintain weight and have good rest .
Next Steps
So, Don't worry and stay alert. Visit nearest professional for a regular checkup and in case of any abnormalities, further workup can be done accordingly.
