LAM Symptoms

People often begin to show symptoms of LAM between 20 and 40 years old. If left untreated, LAM can cause serious and life-threatening health problems.

If you have LAM, you may have one or more of these common symptoms:

  • Chest pain or aches that get worse when you breathe in
  • Extreme tiredness
  • Frequent coughing, which can produce bloody phlegm or mucus in your lungs
  • Severe pain or tightness in the chest and shortness of breath, which can be symptoms of a collapsed lung (pneumothorax)
  • Shortness of breath, which at first may happen only during high-energy activities but over time may start after simple activities, such as dressing and showering
  • Wheezing or a whistling sound when you breathe

You may feel the following symptoms in other parts of the body that are caused by LAM cells:

  • Abdominal pain: Many people who have LAM get benign (noncancerous) tumors in their kidneys. If these tumors grow large enough, they can lead to bleeding in the kidneys or fluid buildup, which can cause pain in the abdomen.
  • Lymph nodes that may be larger than normal: Usually, these larger-than-normal lymph nodes develop in body locations where they cannot be felt, such as the chest. Rarely, larger-than-normal lymph nodes may develop in places where they can be felt, such as in the neck or under the arms.
