Hi there,
This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.

These nodes can be enlarged from recent infection like bacterial pneumonia.

Viral infection is another common possibility.

Next possibility can be anterior mediastinal cancerous growth causing these lymph nodes.

Thymoma is one such example.

Also autoimmune disorders like sarcoidosis can cause these lymph nodes.

However infection is the likely cause.

Can be followed by a repeat CT scan after 3 months to ensure stability or resolution.
Best wishes,
It was my pleasure to help you today.

This is Dr. David

I am a cancer doctor.

those lymph nodes are quite enlarged.

how old are you? are you a smoker?

i am worried that these lymph nodes could contain cancer in them.

the most common cancer would be a lung cancer in these lymph nodes.

smoking would increase your risks for having lung cancer.

you need to see a pulmonologist lung specialist to see if you can get a biopsy of the subcarinal lymph node.

you might need a special procedure like an EBUS or endobronchial ultrasound guided biopsy of the subcarinal lymph node to sample cells from inside of the node to know what is causing the lymph node to be 5.6 cm in size. which is quite large.

is the lymph node 5.6cm or 5.6mm x 1.8cm? in size? that size makes a big difference.
