I am having blood in sputum in the mornings, dry throat and mouth. Can this be cancer?

Hello doctor,

For about a year I have been coughing up mucus with a small fleck or flecks of blood in it. It happens only in the morning and not every day. I have noticed that my throat and mouth are very dry on the days that it happens. I also have little flecks of blood in my snot when I blow my nose first thing in the morning. I have had a chest X-ray that was normal. I recently quit smoking (a few days ago). Should I be concerned that it may be cancer? I am 32. I have also seen an ENT that said everything was normal.

Thank you doctor,

Yes, I do often have dry eyes. My eye doctor says I have ocular rosacea, no foreign body sensation in my eyes though and yes, I do often need a drink while I eat to help swallow. The swallowing issue is what I went to the ENT for where they performed a pharyngogram swallow study and an esophogram which were also normal.

Thank you doctor,

Sometimes I get both. Not very often and I can usually figure out a cause like I get a rash after I cut the grass or weed the flower beds and joint pain if I lay on my side for too long and sit in one position for a long time. I have a desk job, I get caught up in work and forget to move around sometimes.
