[|AI|]  Hi, Thanks for writing in. Lymphnodes in the vernacular region that is in front of the heart are seen in many conditions. It can be present in cancer, tuberculosis, autoimmune conditions or mild infections. Cancer lymph nodes are usually larger than 10 mm in size and can cause pressure effects. Cancer also causes unexplained weight loss and chronic cough and so does TB. However, if your doctor has done a detailed clinical examination then there is no need to worry. If it is due to an infection then it will resolve with treatment. Please take medicines as given and then after consulting your doctor on a follow-up you can get repeat CT scan chest done and that will show the lymph nodes getting smaller or disappear. Please do not worry.
