What is black lung?

There are two types of black lung disease:

  • Simple black lung

  • Complicated black lung, also called progressive massive fibrosis

Simple black lung disease is caused by coal dust collecting in the small airways in your lungs. Most people with simple black lung disease do not have any symptoms.

Some people with simple black lung get worse and develop complicated black lung. This causes large scars in your lungs and makes it very hard to breathe.

Black lung is caused by breathing in coal dust over a long period of time (usually more than 10 years).

How do doctors treat black lung?

There's no treatment for the disease, but doctors can help lessen symptoms. To treat shortness of breath, doctors may prescribe:

  • Oxygen to make breathing easier

  • Pulmonary rehabilitation (a program to help you learn how to breathe with long-term lung disease)

  • Medicines to keep your airways open and free of mucus

Patients with complicated black lung may need a lung transplant. With a transplant, your failing lung is removed and replaced with a healthy one from a donor.
