I currently have a tickly dry cough, some chest tightness and also a feeling of pressure in the chest when having flatulence.

Is this likely to be lung cancer?

I have had the following done.

Echo (3 months ago)
Heart Ultrasound (3 months ago)
Chest X Ray (3 months ago)

MRI Brain and Spine (1 Month ago)
Full Blood Count, Inflammatory Markers, ESR, Lupus, Kidney and Liver Function Tests (1 Month ago)

Endoscopy (Esophagus, Stomach and Duodenum) (2 months ago)

Kidney, Liver, Pancreas, Gallbladder and Bilary Ducts Ultrasound (2 weeks ago)

Neck Ultrasound for Thyroid, Cervical Lymph Nodes, Supraclavicular Lymph Nodes and Virchows Node (2 weeks ago)

Axillary Lymph Node assessment (yesterday)

All of the above tests have come back normal.

I am super anxious for the past 4 months with all these exams. Feels like it's never ending but I have had them all conducted at my own expense as doctors did not believe anything needed done.
