Caufing more then 1 month. Is it cancer?

I am caufing from last 1month. Doctor suggest to do CT scan Thorax, Blood test and Cauf test. The CT scan report findings are: LUNGS: a large heterogeneously enhancing lesion measuring approx. 7.43cm×4.38cm×8.25cm in CS & CC dimensions is noted in the superior segment of left lower lobe. The lesion is causing attenuation and cut off the segmental branch of the bronchus.Two calcified nodules are seen in postero-basal segment of right lower lobe. Suggests possibility of mitotic etiology, However FNAC is advised to rule out other possibilities. PLEURA:There is mild pleural effusion. Mediastinum: Medialtinal structures are within normal limit. Prominent nodes are noted in the lower par-tracheal, sub-carinal, aorto-pulmonary window and pre-vascular stations. CHRST WALL: Chest wall is intact. No bone destruction in axial images. No supraclavicular or axillary lymphadenopathy. No focal lesion in imaged part of the liver or suprarenal areas. Is it cancer??
