What Are MIIPs? / Getting a tissue sample from the lung
Why do I need a lung biopsy?
A biopsy can help doctors figure out what is going on inside you.
Your doctor may send you for a lung biopsy if an x-ray or CT scan showed an abnormal spot on your lung. Not all abnormal spots are dangerous but some can be serious like cancer or an infection. A biopsy can help your doctor figure out what the spot is and how best to treat it. A biopsy can also help you avoid unnecessary treatments.
What is a biopsy?
A biopsy is when a doctor takes a small piece of your tissue in order to figure out what is going on inside you. Doctors do this by looking at the piece of tissue very closely under a microscope.
If they find cancer, they can tell what type of cancer it is and even what kinds of treatments may work best. Some spots are not cancer and there may be no need for treatment. Some spots are due to infection, so treatment would include antibiotics or other medicines.
How is the lung biopsy done?
Biopsies can be done in one of 2 ways:
MIIP biopsies can be done almost anywhere in the body with local numbing medicines alone or with medicines to make you drowsy.
MIIP biopsies usually take around an hour or less. Patients usually go home the same day, usually within a few hours after the biopsy.
What are the risks of a MIIP biopsy?
MIIP biopsies are low risk procedures. There is a small risk of deflating the lung and an even smaller risk of collapsing the lung. If the lung deflates a little bit, it usually does not cause symptoms and will heal naturally. If the lung collapses, your doctor can place a small tube to help your lung inflate again.
Uncommon complications include bleeding, infection, and damage to surrounding tissues.
Your doctor will discuss all of the risks and benefits with you before the biopsy.
What happens after the biopsy?
Your medical team will watch you for several hours after the biopsy to make sure you do not develop bleeding or other uncommon complications. After this rest, you will be allowed to go home. Your doctor will call you with the results of the biopsy, usually in 1-2 weeks.
