I am Dr Arun Tank answering your concern.I advice you should do semen analysis. Which include microscopic examination and chemical examination.If you receive report stating that abnormal malignant cells are seen than its malignancy.I think color of your semen becomes normal after some times. Till that time you can take Doxycycline 100 mg two times a day. Please take it under your doctors guidance.Please drink plenty of water which clear the residual infection.Cancer van be associated with variety of symptoms like cachexia, loss of weight etc.I will be happy to answer your further concern on bit.ly/DrArun.Thank you,Dr Arun TankInfectious diseases specialist,HCM. </s>
