Hello Sir. My mother has problem of coughing from last 12 months. We have taken treatment from well known MD in our city but she never felt considerable relief from any treatment. She has been operated for Brest cancer 4 years ago and is taking antisteroidal medicine for same. Under the guidance of one Oncologist in Nagpur, we performed Pet CT scan for checking possibility of development of metastatic cancer for my mom. But fortunately reports are normal. Now she has been diagnosed for ACE test and the according to her report. Her ACE level is less than normal. Ie; less than 12. So based on this our doctor has given her medicines for TB and some calcium supplements tabs. Now I request you Sir to suggest me proper diagnosis and treatment for my mom.
