Pregnancy is filled with excitement, dreams, and careful planning. Along the way, you may come across unfamiliar medical terms during scans or consultations. One of these is CPAM—Congenital Pulmonary Airway Malformation.Hearing about it for the first time can be unsettling. But with the correct information, you can approach it calmly and confidently.

What is CPAM?

  • CPAM is a developmental condition of the lungs that appears before birth.
  • It happens when a part of the lung forms abnormally and develops small cysts or solid tissue.
  • These cysts are non-cancerous growths.
  • CPAM does not spread to other parts of the body.
You may also hear doctors refer to it as CCAM (Congenital Cystic Adenomatoid Malformation). Both terms refer to the same condition.

How is CPAM Detected?

Most often, CPAM is found during a routine ultrasound in pregnancy. Advanced scans in India, such as level-II ultrasound, can detect lung differences as early as the second trimester.
Detection usually involves:
  • Ultrasound scans: Identifying abnormal lung tissue or cysts.
  • MRI (in some cases): To get more precise imaging if needed.
  • Regular monitoring: It Involves Checking the size of the cysts and their impact on the baby.

Why Does CPAM Happen?

Medical science has not yet pinpointed a single cause for CPAM. Research suggests it is a result of abnormal lung development during foetal growth.
Important points:
  • CPAM is not linked to anything you did or did not do during pregnancy.
  • It is also not usually genetic, though rare family cases have been reported.
  • It occurs in about 1 in every 25,000 to 35,000 pregnancies, according to global data. https://pmc.ncbi.nlm.nih.gov/articles/PMC12224980/

Types of CPAM

Doctors usually classify CPAM into different types based on the size and nature of cysts:
  • Type 1: Large cysts are generally easier to manage.
  • Type 2: Smaller cysts, sometimes linked with other conditions.
  • Type 3: Solid-looking tissue rather than cysts.
Knowing the type helps doctors plan treatment. As a parent, what matters is understanding that these categories guide medical teams, not your daily care routine.

What Happens During Pregnancy?

Once CPAM is detected, your doctor will guide you through the following steps:
  • Regular monitoring: Scans every few weeks to check growth.
  • Measuring CPAM volume: To see if it is affecting heart or lung development.
  • Checking amniotic fluid levels: Imbalances may indicate complications.
In most cases, CPAM remains stable or even shrinks before birth. If it grows, doctors in India may suggest closer monitoring in a specialised centre.

What After Birth?

The approach depends on the baby’s condition after delivery:
  • If the baby is breathing comfortably, no immediate procedure may be needed.
  • If the baby experiences breathing difficulty, doctors may recommend oxygen support or surgical removal of the affected portion of the lung.
  • Surgery, if necessary, typically involves removing only the abnormal part, allowing the rest of the lung to grow normally.
Children often recover well and lead healthy lives after treatment.

Signs to Look Out for After Birth

Even if your baby looks fine initially, stay mindful of:
  • Repeated chest infections
  • Breathing difficulties
  • Wheezing or noisy breathing
  • Slow weight gain
These signs do not always indicate complications, but they should be checked promptly.

Can CPAM Disappear on Its Own?

Yes, in many cases, CPAM reduces in size or becomes almost invisible before birth. However, follow-ups remain important, as small remnants can sometimes cause infections later.

Emotional Preparedness

It is natural to feel anxious when you first hear of CPAM. Remember:
  • Most babies with CPAM do well with monitoring and treatment.
  • Advances in paediatric surgery and neonatal care in India have greatly improved outcomes.
  • You are not alone—support groups and counsellors can help you through the emotional aspects.

Caring for Yourself During Pregnancy

While CPAM is not preventable, your overall health supports your baby’s growth:
  • Eat balanced meals rich in protein, iron, and fresh fruits and vegetables.
  • Stay hydrated, especially in Indian summers.
  • Follow safe prenatal exercises after consulting with a medical professional.
  • Attend every scheduled scan or check-up.
Your care and calmness play an important role in navigating this journey.

Key Takeaways for Parents

  • CPAM is a non-cancerous lung condition detected before or after birth.
  • It is not caused by lifestyle or parental actions.
  • Many cases improve naturally or remain harmless.
  • Monitoring and timely medical decisions ensure good outcomes.
