question: I am 30 years old female non smoker. They found spot on my liver, spleen and lung nodule. The lung nodule is about 2.3cm. two days after the CT i had very sharp chest pain and had to go to emergency. The doctor said it could be pneumonia so i took two kinds of antibiotic for 15days and did another CT after i finished the antibiotics the nodule is still there. I also did bronchoscopy and the result came out negative for bacteria, virus and fungus. I will have another CT two month after.  My life is very busy and stress full on top of that i am also worried about my medical condition. Could this be cancer? What is the possibility?
