Battle Against Nerves

As doctors try to understand neurofibromatosis, patients cope with tumors and people's unpleasant reactions

As a teenager, Jeannine Lancaster started to see spots like mosquito bites on her arms and back. She didn't think much of them then. A decade later, the bumps started to multiply on her face.

The bumps are neurofibromas, or tumors, which have severely disfigured her appearance over the past 18 years. Now, at age 43, Lancaster can't escape the pointing and staring when she goes out of her home. In these situations, she smiles and hands strangers a card:

"If you're curious, I have neurofibromatosis."

Commonly known as NF, the genetic disorder produces benign tumors within and around nerves. The tumors, which can be throughout the body, squeeze the nerves and interrupt signaling in the nervous system. Some people may not show visible bumps but instead suffer from internal effects. Learning disabilities or bone deformities may result through mechanisms not yet understood.

Megan Leaf, a special-education aide in Baltimore's public schools, doesn't suffer any physical disfigurement. For most of her life, she has had learning disabilities and problems with her vision and coordination.

"I don't look like as if anything is different with me, but I might have trouble saying or seeing something," said Leaf, 27. In elementary school, she had trouble seeing the blackboard and needed the help of a paraprofessional to copy notes.

Doctors say the variability of symptoms makes NF difficult to diagnose.

"NF is a common genetic condition, which is underrecognized by both physicians and the public," said Dr. Jaishri Blakeley, director of the Comprehensive Neurofibromatosis Center at Johns Hopkins Hospital. "All those patients don't have a voice and often feel very self-conscious and misunderstood."

Lancaster and Leaf are among an estimated 100,000 Americans with NF, which occurs in one out of 3,000 individuals. According to the Children's Tumor Foundation, an advocacy group, this makes the condition more prevalent than cystic fibrosis, hereditary muscular dystrophy, Huntington's disease and Tay-Sachs disease combined.

There is no cure for any of the three subtypes of NF. But surgeons can remove tumors when they become painful or threaten normal bodily functions, such as vision and movement. In rare cases, tumors may become malignant and are treated as other cancers would be, with radiation or chemotherapy.

Lancaster underwent separate surgeries to remove tumors on her lung and neck, which were encroaching on her spine and becoming painful. But the operations have left her in more pain, she says.

"I sometimes feel electricity shooting down my body ... just completely unexpected," Lancaster said. "It lasts for seconds and then goes away."

Even so, Lancaster struggles more with the psychological and social aspects of NF.

"I can't deal with most people ... the rudeness people have; the outright pointing, staring, screwed up face while looking at me," said Lancaster, a retired State Department employee who lives in Suitland. "When I go out, I need to have my guard on. I'm ready for a comment or a look, and that's why I have my cards."

Most people are unfamiliar with NF, she says, and they often ask if the bumps are mosquito bites. But from time to time, she hears grossly offensive comments.

"On Halloween, a kid asked me if I had a mask on," Lancaster said. "And that really hurt my feelings."

To improve her appearance, dermatologists removed several tumors from her face in 2006. But they just grew back, Lancaster said.

Doctors usually discourage surgery for cosmetic reasons.

"It's not recommended procedure because there are just too many to remove," Blakeley said. "And it may not be worth the risk of sensory and nerve damage."

Doctors are trying to understand the symptoms and genetics of NF and the disorder's implications on a patient's life.

Patients may show a range of symptoms, including cafe-au-lait spots, which are flat, pigmented spots on the skin, named after the French term for coffee with milk because of their light tan color. Some adults may exhibit no symptoms and may be unaware they are carriers until their children are diagnosed.

"The researchers focus on the illness, but the patients focus on discrimination," Blakeley said. "They might not have a life-threatening form, but every day is like being a cancer survivor for them."

Leaf, like Lancaster, finds it difficult to deal with people's reactions. "When I bring up NF, people are not accepting of that," she said.

She underwent surgery 14 years ago to remove a tumor growing on her cerebellum, the region of the brain that controls motor function. The Charles Village resident is unable to drive or even walk in a straight line, so she depends on public transportation. Despite these challenges, Leaf recently received a master's degree in teaching at the College of Notre Dame.

"My mother has taught me that I am no different from everyone else and has always strived to make me independent," Leaf said.
