Surgery allows me to focus on the ""moment"" that is almost a spiritual experience. | Community involvement | While I was practicing in Philadelphia, I started a community 10k and 5k run in Washington Crossing to beat lung cancer. Not only to raise for money for lung cancer research but also to educate the public about lung cancer screening. As a thoracic surgeon, my role extends beyond operating. I potentially can save more – even lives – through education. | Personal interests | I enjoy martial arts, meditation, hiking, camping and fishing. | Image | Lehigh Valley Hospital is ranked 42th for pulmonology and lung surgery on the 2025-2026 U.S. News & World Report Best Hospitals list. | ".

Philosophy of care | In my area we’re dealing with people who are frightened. I’m trying to help patients deal with all of the information they’ve been hearing, and I’m trying to dispel all of the myths. It’s a matter of education and mutual trust. I’m there to do whatever I can do for them, even if it’s just a matter of easing their pain. | Also, I am a member of the thoracic cancer multidisciplinary consultation team. Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | Medicine was not my first choice. I wanted to be first oboe in the New York Philharmonic. I have a love of biochemistry and science, and I like people. One day, I just decided I wanted to be a doctor. I wouldn’t change it for anything in the world. | Community involvement | I’m part of the National Cancer Institute’s community cancer program. Our goal is to be able to give the same care and treatment to everyone, whether they have health insurance or not. | Personal interests | I still play the oboe and will always have a love of music.

Philosophy of care | As a physician dedicated to the comprehensive care of cancer patients, my philosophy centers on empathy, communication and personalized treatment. I build a trusting and compassionate relationship with my patients, ensuring they are fully informed about their condition and treatment options. I am committed to understanding their unique goals and wishes and tailoring their treatment plans accordingly. I integrate leading-edge advancements by offering participation in clinical trials, contributing to the progress of oncology care. My goal is not only to provide exceptional medical expertise, but also to support and empower patients, fostering collaboration that prioritizes physical and emotional well-being. | Why I entered medicine | I chose a medical career with a specific focus on cancer care because it offered me the opportunity to seamlessly merge the dynamic advancements in cancer biology with the profound personal connections essential for understanding and supporting my patients. The ever-evolving science of cancer has fascinated me, driving my commitment to staying at the forefront of breakthroughs and innovations. However, it is the deeply personal nature of medicine that truly inspires me – the privilege of learning about my patients, understanding their unique stories and collaborating with them as they heal. This dual passion for scientific progress and compassionate patient care motivates me. | Community involvement | I contribute to public education with the presentation, detection and treatment of lung cancers. In doing so I empower individuals with knowledge, foster early detection and encourage proactive engagement in their lung health. | Personal interests | I have a deep love for exploring diverse cultures through culinary adventures, mastering the art of cooking international cuisine and indulging in the creativity of baking. I am also passionate about personal fitness, recognizing the importance of a healthy and balanced lifestyle.

His top areas of expertise are Lung Cancer, Pleuropulmonary Blastoma, Small Cell Lung Cancer (SCLC), Richter Syndrome, and Bone Marrow Aspiration.

Philosophy of care | Effective medical care begins with a deep understanding of each patient’s circumstances and needs. The physician-patient relationship is foundational and must be a two-way dialogue built on trust and respect. I prioritize learning what truly matters to you and your family. I offer treatment recommendations and options that align with your values, preferences and goals. While my clinical focus is on blood disorders and blood cancers, listening carefully and tailoring care to patients is the heart of everything I do. I provide guidance and recommendations, but the decisions ultimately belong to you, the patient. I strongly believe in a team-based approach, where collaboration and communication yield the best outcomes. | Why I entered medicine | When I started college, medicine was the farthest thing from my mind; I was an economics major and took the MCAT on a whim. To my surprise, I scored far better than expected for someone without a science background, and that led me to medical school. Looking back, I can’t imagine doing anything else. Medicine – and caring for patients – has become my true passion. My path into the field was unconventional but led me exactly where I was meant to be. Practicing hematology and oncology isn’t just a career for me – it’s the only thing I can see myself doing. | Community involvement | As a part of cancer center leadership, I participate in local events and charities for patients with cancer and blood diseases, including speaking to the leukemia/lymphoma society. I am particularly fond of events centered around running for cancer charities. | Personal interests | Running is a personal passion of mine – second only to medicine and my family.

"Philosophy of care | Every new patient I meet, along with their families and loved ones, is encouraged to be an active participant in the plan of care and subsequent recovery. While being diagnosed with cancer often leads one to feel as though they have ""lost control,"" people need to be empowered to regain that sense of control and a positive outlook going forward. Through open communication and education, that becomes more tangible. | Also, I am a member of the breast cancer multidisciplinary consultation team. Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | The practice of medicine is the perfect mix of art and science - my two favorite subjects throughout early education. That, coupled with a strong desire to positively impact the lives of others, stimulated my interest early on in pursuing a career in medicine. With ongoing research and technical advances in virtually all fields, it is also a career path that promises unending challenges, intellectual stimulation and opportunities for continual improvement in patient outcomes. | Community involvement | Through a generous contribution of time and materials from a relative, I was able to supply our Lehigh Valley Hospital-Muhlenberg gift shop with plush seat belt covers designed with my breast cancer patients in mind. One hundred percent of the proceeds are donated to the Pink Ribbon Fund helping our underserved community members get mammograms. We are on our second shipment and hope to continue providing comfort and financial assistance to customers and benefactors, respectively. | Personal interests | Along with busy and fulfilling careers, my husband and I try to keep involved with our two children's academic and extracurricular activities as much as possible. When our schedules permit, we enjoy brief getaways to the beach and all of the amenities there. Finally, if the opportunity presents itself, I enjoy experimenting with recipes (especially baking) and jewelry design.

Philosophy of care | Personalized care starts during my first meeting with a patient and family. That's when I get to know the patient as completely as possible.

Together we review your diagnostic information and give you a written opinion reflecting the scope of your condition and recommendations for your best course of care. | Why I entered medicine | When I was young, I didn't like seeing doctors.

My grandmother died of uterine cancer in the 1960s. During her battle, I felt helpless. That is what attracted me to cancer research. Now I see the amazing progress we are making through cancer research. | Community involvement | I served on the state board of the American Cancer Society.

Philosophy of care | Finding out you have cancer is life altering for both you and your loved ones. There is a lot of misinformation out there, especially in today’s social media environment, and that can cause more harm than the initial news of your diagnosis. My goal is to provide information to help you make the right decisions during these trying times. Medicine is indeed a shared decision process with the physician and the patient (along with the family). I hope to provide relevant information to help you navigate your diagnosis and treatment plans and provide optimal support for you and your family. | Why I entered medicine | Medicine was the only career choice for me. I can’t see myself doing anything else or practicing any other field of medicine. Before age 10, I was heavily involved in helping my mother design her clinical practice. In my teenage years, I spent a lot of time in several hospitals in the city volunteering in various departments to get more exposure. In my undergraduate training, I spent time in a cancer lab that focused on drug design. Naturally, the next step was medical school. | Community involvement | Health care is a basic human necessity. I helped to staff a volunteer clinic in medical school with fellow medical students and helped with fundraising for the clinic. We saw patients free of charge and had gift cards for those who needed help with the cost of their medications. We were also able to assist the patients with nutrition, since the clinic was part of a food bank. I hope to start or participate in a similar clinic here someday. | Personal interests | Outside of medicine my biggest interest is in cosmology – the origins of the universe. We live in such a vast universe that spans such a grand period of time; one can only imagine what lies outside our own solar system. I've had the privilege to travel to remote sites around the country and use large dome telescopes to gaze at distant stars. | My family and I love to travel. Each year we try a different area to soak up its beauty and culture, although we do have favorites. Dr. Nadeem is rated as an Advanced provider by MediFind in the treatment of Pleuropulmonary Blastoma.
