Medical Malpractice Lawyers Investigate Claims in Rockland County & Bergen County
Medical malpractice lawyer Barry S. Kantrowitz aggressively advocates for victims of medical negligence throughout New York and New Jersey. Our full-service law firm represents cancer patients who have unnecessarily suffered due to a health care provider’s failure to diagnose cancer. Barry leads a team of attorneys that can help ensure you receive the support and access to treatment to which you are entitled.
You have the right to expect the highest standard of medical care from your licensed physician. When a doctor or health care professional fails to act in accordance with the standards set by the medical profession, your health and your life is at stake.
Early Detection of Cancer is Crucial
The first step for successful cancer treatment is early detection. When your diagnosis of cancer is delayed or overlooked, your chance of defeating the disease is reduced significantly. Treatment becomes more complicated. Suddenly, you face extreme bodily and mental challenges. In addition to the emotional turmoil, you may not be able to work or bring in the same level of income as before, and the medical bills may be overwhelming.
When Does Failure to Diagnose Cancer Constitute Medical Malpractice?
You should speak with our medical malpractice lawyer if you or a loved one has one of these cancers that was misdiagnosed, delayed in diagnosis or completely overlooked:
- Lung cancer
- Breast cancer
- Pancreatic cancer
- Skin cancer
- Prostate cancer
- Colon cancer
- Bladder cancer
Your doctor may have misread or misinterpreted a PAP smear, MRI, CT scan, chest X-ray or mammogram. You may have had a specific complaint or concern over possible symptoms that were ignored by your healthcare provider. All the appropriate diagnostic testing measures may not have been pursued.
How Do I File Medical Malpractice Lawsuits?
At KGG, we have investigators who can uncover mistakes that were made in a doctor’s office, during a routine check-up or at lab testing facilities. Our medical malpractice attorneys get to the facts and use them to confront those whose negligence harmed you. Misdiagnosis or failure to diagnose cancer is one example of a medical malpractice case. Medical malpractice lawsuits are subject to a statute of limitations, so you should speak to a personal injury lawyer right away.
We work for our medical malpractice and personal injury clients on a contingency fee basis. Any attorney fees we receive will come from your settlement agreement or verdict from trial. If we do not win your case, you will not be charged attorney fees. Our law firm has the experience and dedication to excellence that gets our clients positive results.
If a Rockland County or Bergen County health care professional has betrayed your trust, Kantrowitz, Goldhamer, Graifman, Perlmutter & Carballo, P.C. can help – contact us today. Call toll free at (866) 971-0927 to schedule your free initial consultation at either one of our convenient law offices within our community to speak with a misdiagnosis attorney.

KGG Law, and Barry Kantrowitz in particular, set the bar high for what a thorough, practical, strategic, compassionate and smart lawyer can be. Everything about Barry's advice and representation was exemplary and the stress mitigation that resulted was invaluable. On top of that, the ultimate result Barry achieved was beyond what was reasonable to expect and we are forever grateful. Often, people say that you hire a lawyer to prevent a problem. Sometimes, unfortunately, you need an attorney to solve a problem and I could not recommend Barry and his firm any more highly in that regard.Posted on Google

They kept us informed throughout the entire process and made what could have been a very stressful situation much easier to handle. We truly appreciated their dedication, honesty, and hard work. Thanks to their support, my dad felt confident every step of the way.

Kate Carballo is a dedicated, passionate, and creative attorney whom I had the pleasure to lecture with at a state trial lawyer's conference. Kate's lecture demonstrated how she uses her innovative and "out-of-the-box thinking" to achieve outstanding results for her injured clients. That Kate is certified by the Supreme Court of New Jersey as a civil trial attorney is a testament to her skills, experience and commitment to excellence.Posted on Google

Was referred to KGG law by a friend and could not have asked for better legal representation. They walked me through every step of the process after my accident and began every call with “ how are you feeling” which was just one example of how much they care about their clients. They handled my case very efficiently, professionally and courteously. My attorney Kate Carballo was a rock star! So clearly experienced, she consistently made me feel at ease with the process. Highly recommendPosted on Google

We had a great experience with the team at KGG Law. While it was a traumatic time for our family, they made it very easy for us and explained all of our options. They even performed due diligence to make sure that after our settlement, there would be no further issues which I think is even more important than the settlement itself. Thank you!Posted on Google
