Tuberculosis

Hi! I have xray on january saying i have 2 non calcified nodules. I went for follow up ctscan. Done all the blood test and sputum test. And skin test. Turns out all normal. I almost under go lung biopsy but that didn't push tru because the doctor say the nodules are now getting smaller from the previous ctscan. Now my specialist wanted to repeat again the skin test. Always saying and concluding its tb even if i have all normal result. It is possible i have all normal result and still have tb? Or it is possible that a scar of a tb in the lungs will get smaller even if i dont take any meds coz i know that it's impossible to get rid of them. Or is this lung cancer? Please help me. Tweet
