Hello,
As per my clinical experience, there are various reasons for dark phlegm as severe
respiratory tract infection,
pneumonia or others. The cancer is very less likely as there are no associated features of
weight loss,
chronic fever, loss of appetite and others. The pneumonia is striking possibility. However, in my clinic, I do recommend:
- Thorough clinical examination
- History of
smoking and family history of cancer if any,
- Relevant investigations of
@ Complete hemogram
@ Sputum microscopy
@ X-ray chest with or without CT scan thorax
If your any of the reports are available at present, kindly share with me during follow up chat for further discussion.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Bhagyesh V. Patel, General Surgeon
