With earlier diagnosis and newer treatment, patients with LAM are living longer, with some living more than 20 years after diagnosis. Your doctor will monitor your condition to see if it is stable or getting worse and causing serious complications. Also, your doctor may recommend other medical care, including vaccines, lifestyle changes, and pregnancy and birth control planning.

LAM is diagnosed based on your medical history and the results from diagnostic lung function tests, imaging tests such as high-resolution CT scans, VEGF-D blood tests, or other procedures.

The signs and symptoms of pneumonia can be mild or severe and may include lung cysts, increased VEGF-D levels, reduced lung function, reduced, oxygen levels in the blood, chest pain or aches, fatigue, frequent cough, shortness of breath, and wheezing. Possible complications may include tumors in the kidneys, blood in the urine, enlarged lymph nodes, pleural effusions, pneumothorax or collapsed lung, and swelling.

Researchers do not know the exact cause of LAM or why it mainly affects women, but they believe genes and the female hormone estrogen play a role.

Pneumonia can be very serious and even life-threatening. Vaccines can help prevent some types of pneumonia. Good hygiene (washing your hands often), quitting smoking, and keeping your immune system strong by getting regular physical activity and eating healthy are other ways to lower your risk of getting pneumonia.
