I have a lump Inside my tongue on the right that is quite painful. Now I have one staying on the left side as well. I have heart and lung issues, I wear dentures, ischemic colitis along with many other medical issues. I would like to know if it is something I need to be concerned about our if I can try to ignore it until it goes away, if it s not harmful. I could possibly have metastatic lung cancer, waiting to get needed tests. If you could possibly let me know how serious this could be. Thank you
